3 IT security
Observe the following recommendations to operate the product safely.
General
▪ Ensure that only authorized personnel have access to the device.
▪ Only use the device within an ESP (electronic security perimeter). Do not
connect the device to the Internet in an unprotected state. Use mecha-
nisms for vertical and horizontal network segmenting and security gate-
ways (firewalls) at the transition points.
▪ Ensure that the device is only operated by trained personnel who are fa-
miliar with IT security.
Commissioning
Observe the following recommendations for device commissioning:
▪ User IDs must be unique and assignable. Do not use a "Group account"
function or the "Auto login" function.
▪ Activate the "Auto logout [►Section 9.2.2, Page 109]" function.
▪ Restrict the rights of the individual user groups as much as is feasible; this
helps avoid errors during operations. A user with the "Operator" role, for
example, should only perform operations and should not be able to
change any device settings.
▪ Delete or disable the default "admin" user ID. This requires first creating a
new user account with the "Administrator" role. You can then use it to
delete or disable the default "admin" account.
▪ Deactivate service user access [►Section 9.2.3, Page 110].
▪ Enable SSL/TLS encryption [►Section 9.2, Page 107]; access to the de-
vice is then only possible using the SSL/TLS protocol. In addition to en-
crypting communication, this protocol also checks the authenticity of the
server.
▪ Use TLS version 1.2 or higher wherever possible.
▪ Integrate the device into a public key infrastructure. Create your own SSL
certificates for this if necessary and then import them.
▪ Connect the device to a central log server by using the syslog interface
[►Section 9.6, Page 118].
▪ Only use the SNMP function if you can ensure that the communication is
protected by external security equipment.
Operation
Observe the following recommendations during device operation:
▪ Change the password at regular intervals.
▪ Export the security log [►Section 9.36.1, Page 325] at regular intervals.
▪ Check the log files regularly for unauthorized system access and other se-
curity-related events.

4.1 Scope of delivery
The motor-drive unit is packaged with protection against moisture and is de-
livered as follows:
▪ Motor-drive unit
▪ Product documentation
Please note the following:
1. Check the shipment for completeness on the basis of the shipping docu-
ments.
2. Store the parts in a dry place until installation.
3. The product must remain in its airtight, protective wrapping and may only
be removed immediately before installation.
4.2 Function description
The motor-drive unit adjusts the operating position of on-load tap-changers
in regulating transformers to the individual operating requirements.
The tap-change operation is initiated by activating the motor-drive unit (a sin-
gle control impulse is triggered, for example via the optional "Automatic volt-
age regulation AVR basic/pro" function package). This adjustment operation
is always completed regardless of any other control impulses issued during
the tap-change operation. In the standard design, the next tap-change oper-
ation can only proceed once all control devices have reached their resting
positions.
Behavior in the event of a voltage interruption
Should the voltage be interrupted during an on-load tap-change operation,
once the voltage supply returns, the motor-drive unit completes the started
on-load tap-change operation.

4.5.1 Indication field
A clear indication field is fitted in the motor-drive unit. The pointer and opera-
tions counter are mechanically driven and indicate the tap-change operation
sequence and operating position of the motor-drive unit. The reset wheel on
the operations counter is sealed at the factory.

regulating range currently used
2 Tap position indicator
3 Tap-change indicator: Shows the
current position of the control cam
(33 tap-change indicator sections
per operating position)
4 The mechanical operations
counter shows the overall number
of tap-change operations
4.5.2 Anti-condensation heater
The anti-condensation heater is designed as a panel heater which also acts
as the front cover of the swing frame.
The design of the motor-drive unit and panel heater ensures that air circu-
lates inside the motor-drive unit and therefore that there is a constant interior
temperature which is always higher than the outside temperature.
4.5.3 Swing frame/terminal rail
The swing frame protects all electrical and mechanical parts of the motor-
drive unit behind the swing frame against accidental contact.
The terminal rail behind the swing frame enables easy electrical connection
of the motor-drive unit. Vertically arranged cap rails with the correspondingly
mounted terminal bars ensure that the connection wiring is easy to install.

4.5.4 Position transmitter equipment
NOTICE
Damage to the on-load tap-changer and motor-drive unit!
Damage to on-load tap-changer and motor-drive unit due to incorrect use of
position transmitter equipment.
►Only circuits stated in the chapter Technical data for position transmitter
equipment [►Section 14.3, Page 380] may be connected to the position
transmitter module connections.
►The switchover point of the position transmitter equipment in the motor-
drive unit is not the same as the switchover point of the diverter switch
operation. This depends on the type of diverter switch. This fact should
be noted when project planning the locking circuits between the motor-
drive unit and external equipment (e.g. transformer circuit breaker).
►Therefore, the "Tap changer in operation" position transit contact shown
in the connection diagram should be used for external monitoring, locking
and control purposes instead of the position transmitter equipment.
The position transmitter equipment is used to indicate the operating position
of the on-load tap-changer/de-energized tap-changer when idle.
The remote displays are available in various versions.
The position transmitter module for connection by the customer is located on
the terminal rail [►Section 4.5.3, Page 32].
For more information about the position transmitter equipment, see Techni-
cal data for position transmitter equipment [►Section 14.3, Page 380].
4.5.5 Transmission gear cover plate
WARNING
Danger of death and severe injury from electrical voltage!
Danger of death and severe injury from electrical voltage if the transmission
gear cover plate is not fitted.
►Never start up motor-drive unit without transmission gear cover plate.

4.9 Emergency operation during switching blocking (X100
bridge)
The monitoring function of the on-load tap-changer is only active when the
device is ready for operation and issues a signal at the digital output Status
OK.
If your device is equipped with the OLTC monitoring expert function pack-
age, the monitoring system can block further tap-change operations where
necessary. In this case, the monitoring system will report the event Blocking
active. If operation needs to be resumed despite the cause of the event not
being eliminated, you can activate emergency operation by inserting the
X100 bridge.
If the X100 bridge is inserted, drive blocking by the monitoring system is
switched to inactive. All operating values continue to be recorded and stored
by the monitoring system.

NOTICE
Damage to the transformer and/or on-load tap-changer
If the Blocking active event is present in the monitoring system, then the
cause of the event has to be analyzed before activating emergency opera-
tion. Performing additional tap-change operations on the motor-drive unit
without analyzing the cause may lead to on-load tap-changer and/or trans-
former damage.
►Check what caused the Blocking active event and decide whether to con-
tinue operating the on-load tap-changer based on the cause.
►Export the service data and contact Maschinenfabrik Reinhausen GmbH.

5 Packaging, transport and storage
5.1 Packaging
The products are sometimes supplied with sealed packaging and sometimes
in a dry state, depending on requirements.
Sealed packaging surrounds the packaged goods with plastic foil on all
sides.
Products that have also been dried are identified by a yellow label on the
sealed packaging. In the dry state, delivery is also possible in a transport
container.
The information in the following sections should be applied as appropriate.
5.1.1 Suitability
NOTICE
Property damage due to incorrectly stacked crates!
Stacking the crates incorrectly can lead to damage to the packaged goods.
►The outer marking on the packaging states if, for example, the on-load
tap-changer or selector has been packed upright. Never stack these
crates.
►General rule: Do not stack crates above a height of 1.5 m.
►For other crates: Only stack up to 2 equally sized crates on top of one an-
other.
The packaging is suitable to ensure undamaged and fully functional means
of transportation in compliance with local transportation laws and regula-
tions.
The packaged goods are packed in a sturdy crate. This crate ensures that,
when in the intended transportation position, the packaged goods are stabi-
lized to prevent impermissible changes in position, and that none of the parts
touch the loading surface of the means of transport or touch the ground after
unloading.
Sealed packaging surrounds the packaged goods with plastic foil on all
sides. The packaged goods are protected from humidity using a desiccant.
The plastic foil was bonded after the desiccant is added.

5.2 Transportation, receipt and handling of shipments
WARNING
Danger of death or severe injury!
Danger of death or serious injuries due to tipping or falling load.
►Only transport the crate when closed.
►Do not remove the securing material used in the crate during transport.
►If the product is delivered on a pallet, secure it sufficiently.
►Only trained and authorized persons may select the sling gear and se-
cure the load.
►Do not walk under the suspended load.
►Use means of transport and lifting gear with a sufficient carrying capacity
in accordance with the weight stated on the delivery slip.
In addition to oscillation stress, jolts must also be expected during trans-
portation. In order to prevent possible damage, avoid dropping, tipping,
knocking over and colliding with the product.
If a crate tips over, falls from a certain height (e.g. when slings tear) or is
subject to an unbroken fall, damage must be expected regardless of the
weight.
Every delivered shipment must be checked for the following by the recipient
before acceptance (acknowledgment of receipt):
▪ Completeness based on the delivery slip
▪ External damage of any type
The checks must take place after unloading when the crate or transport con-
tainer can be accessed from all sides.

Visible damage
If external transport damage is found upon receipt of the shipment, proceed
as follows:
▪ Immediately record the identified transport damage in the shipping docu-
ments and have this countersigned by the carrier.
▪ In the event of severe damage, total loss or high damage costs, immedi-
ately notify the manufacturer and the relevant insurance company.
▪ After identifying damage, do not modify the condition of the shipment fur-
ther and retain the packaging material until an inspection decision has
been made by the transport company or the insurance company.
▪ Record the details of the damage immediately on site together with the
carrier involved. This is essential for any claim for damages.
▪ Photograph damage to packaging and packaged goods. This also applies
to signs of corrosion on the packaged goods due to moisture inside the
packaging (rain, snow, condensation).
▪
NOTICE! Damage to packaged goods due to damaged sealed packag-
ing. If the product is delivered in sealed packaging, check the sealed
packaging immediately. If the sealed packaging is damaged, do not under
any circumstances install or commission the packaged goods. Either re-
dry the dried packaged goods as per the operating instructions, or contact
the manufacturer to agree on how to proceed.
▪ Identify the damaged parts.
Hidden damage
When damages are not determined until unpacking after receipt of the ship-
ment (hidden damage), proceed as follows:
▪ Make the party responsible for the damage liable as soon as possible by
telephone and in writing, and prepare a damage report.
▪ Observe the time periods applicable to such actions in the respective
country. Inquire about these in good time.
With hidden damage, it is very hard to make the transportation company (or
other responsible party) liable. Any insurance claims for such damages can
only be successful if relevant provisions are expressly included in the insur-
ance terms and conditions.
5.3 Storage of shipments
Packaged goods dried by Maschinenfabrik Reinhausen
Upon receipt of the shipment, immediately remove the packaged goods
dried by Maschinenfabrik Reinhausen from the sealed packaging and store
air-tight in dry insulating fluid until used if the packaged goods were not sup-
plied in insulating fluid.
Non-dried packaged goods
Non-dried packaged goods but with a functional sealed packaging can be
stored outdoors when the following conditions are complied with.

When selecting and setting up the storage location, ensure the following:
▪ Protect stored goods against moisture (flooding, water from melting snow
and ice), dirt, pests such as rats, mice, termites and so on, and against
unauthorized access.
▪ Store the crates on timber beams and planks as a protection against ris-
ing damp and for better ventilation.
▪ Ensure sufficient carrying capacity of the ground.
▪ Keep entrance paths free.
▪ Check stored goods at regular intervals. Also take appropriate action after
storms, heavy rain or snow and so on.
Protect the packaging foil from direct sunlight so that it does not disintegrate
under the influence of UV rays, which would cause the packaging to lose its
sealing function.
If the product is installed more than 6 months after delivery, suitable mea-
sures must be taken without delay. The following measures can be used:
▪ Correctly regenerate the drying agent and restore the sealed packaging.
▪ Unpack the packed goods and store in a suitable storage space (well ven-
tilated, as dust-free as possible, humidity < 50% where possible).
5.4 Unpacking shipments and checking for transportation
damages
▪
NOTICE! Transport the packaged crate to the place where the packaged
goods are to be installed. Do not open the sealed packaging until just be-
fore installation. Otherwise, damage to the packaged goods may occur
due to ineffectively sealed packaging.
▪
WARNING! When unpacking, check the condition of the packaged
goods. Place the packaged goods in an upright crate and protect it from
tipping out. Otherwise, the packaged goods may become damaged and
serious injuries may result.
▪ Check the completeness of the accessories kit using the delivery slip.

6.2 Mounting drive shafts and bevel gear
The process of mounting the drive shafts and bevel gear is described in the
installation and commissioning instructions for the on-load tap-changer / de-
energized tap-changer.
6.3 Centering on-load tap-changer and motor-drive unit
WARNING
Danger of death or severe injury!
Danger of death or severe injury due to motor-drive unit starting up by acci-
dent and due to electric voltage!
►Before starting any coupling work make sure that the motor protective
switch is tripped.
►Carry out any adjustment work in manual mode only.
►When manually operating the motor-drive unit only use the hand crank
provided for this purpose.
►Note that the hand crank safety switch causes a 2-pole disconnection of
the motor circuit but that the control circuit is not interrupted.
NOTICE
Damage to property!
The on-load tap-changer will be damaged by incorrectly centering the mo-
tor-drive unit.
►Do not perform more than 250 tap-change operations on the on-load tap-
changer. If more than 250 tap-change operations are performed, com-
pletely fill oil compartment with insulating oil and lubricate sliding surfaces
of contacts on selector and selector gear with insulating oil.
The following steps for centering the on-load tap-changer and motor-drive
unit do not apply to the DEETAP® DU or COMTAP® ARS devices. The
process for centering the motor-drive unit and DEETAP® DU or COMTAP®
ARS devices is described in the relevant operating instructions.
One on-load tap-change operation is represented by one rotation of the tap-
change indicator. This indicator is divided into 33 tap-change indicator sec-
tions, each of which corresponds to one hand crank revolution in the stan-
dard motor-drive unit design. The time of the switchover depends on the on-
load tap-changer / de-energized tap-changer type, but is always 2 tap-
change indicator sections upstream of the area marked in gray on the tap-
change indicator at the latest.
To center the on-load tap-changer and motor-drive unit, proceed as follows.
1. NOTICE! Move the on-load tap-changer / de-energized tap-changer and
the motor-drive unit into the adjustment position before commencing any
adjustment work. Ensure that the tap position indicators for the motor-

drive unit and the on-load tap-changer / de-energized tap-changer match.
Otherwise damage to the on-load tap-changer and transformer may re-
sult.
Figure 42: Adjustment position
2. Attach the hand crank in the motor-drive unit to the shaft end located in
the upper cover plate. This activates a hand crank interlock switch, which
disconnects the motor circuit at 2 poles.

3. Turn the hand crank clockwise until the diverter switch operation begins.
When turning the hand crank, observe the tap-change indicator, which
mechanically reflects the progress of the tap-change operation.
Figure 44: Turning the hand crank
4. Once the diverter switch operation begins, continue to turn in the same di-
rection while counting the tap-change indicator sections required for the
pointer to reach the mid-position of the area marked in gray on the tap-
change indicator. Note the number counted (value A) and the direction of
rotation (example: A=2).
Figure 45: Counting the tap changes needed to reach the mid-position
5. If value A is greater than 8 tap-change indicator sections, the tap-change
operation has been completed correctly. If value A is less than 8 tap-
change indicator sections, turn another 8-A tap-change indicator sections

rection while counting the tap-change indicator sections required for the
pointer to reach the mid-position of the area marked in gray on the tap-
change indicator. Note the number counted (value B) and the direction of
rotation (example: B=5).
Figure 48: Counting the tap-change indicator sections needed to reach the mid-position
8. If value B is greater than 8 tap-change indicator sections, the tap-change
operation has been completed correctly. If value B is less than 8 tap-
change indicator sections, turn another 8 B tap-change indicator sections
in the same direction (example: 8-5=3) to complete the tap-change opera-
tion. Then turn in the opposite direction until the pointer is in the mid-posi-
tion of the area marked in gray on the tap-change indicator.
Figure 49: Completing the diverter switch operation
9. If the values obtained for A and B are identical, the on-load tap-changer
and the motor-drive unit are correctly coupled (a slight imbalance of maxi-
mum 1 tap-change indicator section is permitted). If the values obtained
for A and B are different, establish correction value C by halving the differ-
ence between A and B: C=|(A-B) x 0.5|
Example: C=|(2-5) x 0.5|=|-1.5|=1.5
Maschinenfabrik Reinhausen GmbH 2020
68
6385142/08 EN
ETOS® ED
Also take numbers after the decimal point into account.
10. If the correction value |C| is less than 0.5 tap-change indicator sections,
no further action is required. Refer to item 18 for how to proceed next.
11. Use the hand crank to crank in the direction in which the determined
value A or B was higher (example: counter-clockwise, because B > A)
until the diverter switch operation begins.
12. Once the diverter switch operation begins, continue turning another 8
hand crank revolutions in the same direction to correctly complete the di-
verter switch operation.

13. Uncouple the motor-drive unit and vertical drive shaft by removing the
coupling brackets. After uncoupling, do not turn the drive shaft any fur-
ther.
Figure 50: Uncoupling the motor-drive unit and drive shaft
14. Operate the motor-drive unit using the hand crank in the same direction,
continuing by C tap-change indicator sections on the tap-change indica-
tor (example: 1.5 tap-change indicator sections).
15. Couple the motor-drive unit and on-load tap-changer by refitting the verti-
cal drive shaft (tightening torque 9 Nm). Do not turn the drive shaft or
output shaft of the bevel gear or motor-drive unit any further.
16. Continue to turn in the same direction while counting the tap-change in-
dicator sections required for the pointer to reach the mid-position of the
area marked in gray on the tap-change indicator. Note the number
counted (value A) and the direction of rotation. If value A is greater than
8 tap-change indicator sections, the tap-change operation has been
completed correctly. If value A is less than 8 tap-change indicator sec-

tions, turn another 8 A tap-change indicator sections in the same direc-
tion (example: 8-4=4) to complete the tap-change operation. Then turn in
the opposite direction until the indicator is in the mid-position of the area
marked in gray on the tap-change indicator. Check the coupling again as
described previously.
17. The pointer of the tap-change indicator must be in the mid-position of the
area marked in gray once the on-load tap-change operation with the
hand crank is complete.
Figure 51: Pointer in the mid-position
18. Once coupling is complete in both directions, check by carrying out sev-
eral on-load tap-change operations and check that the on-load tap-
changer and motor-drive unit are in the same tap position.
6.4 Connecting the ISM® assemblies
WARNING

Risk of fatal injury due to connection errors.
►Ground the device using the grounding screw on the housing.
6.4.1 Cable recommendation (ISM® assemblies)
Please note the following Maschinenfabrik Reinhausen GmbH recommenda-
tion when wiring the device.
▪ Excessive line capacitance can prevent the relay contacts from interrupt-
ing the contact current. In control circuits operated with alternating current,
take into account the effect of the line capacitance of long control cables
on the function of the relay contacts.
▪ If you want to route Ethernet connections from a control cabinet or build-
ing, we recommend using fiber-optic cables (in accordance with the
IEC 61850-90-4 recommendation).
▪ Ensure that the copper cables used have a temperature resistance of
70°C.

6.4.3 Notes on connecting to the MR sensor bus
The optionally available MR sensor bus function lets you connect digital and
analog sensors to the device over Modbus RTU. The MR sensor bus sup-
ports the connection of up to 31 sensors (Modbus slaves). The ISM® device
operates as the Modbus master.
Ensure that no other Modbus master is connected over the MR sensor bus.
Assign a unique Modbus address to each sensor you are connecting over
MR sensor bus. The MR sensor bus may experience errors if multiple sen-
sors are using the same Modbus address.
Observe the following notes for connecting the sensors:
▪
NOTICE! Damage to the device or sensor. Connect all of the sensors to
the potential equalization rail to avoid circulating currents over the MR
sensor bus.
▪ The MR sensor bus uses Modbus in a 2-wire configuration (2W). The 4-
wire configuration (4W) is not supported.
▪ You must connect the sensors via a shielded line with 3 conductors (D0,
D1, Common). The data lines (D0, D1) must be in twisted pairs. Note the
cable recommendation.
▪ Stub lines from the bus node to the respective device must be shorter
than 20 m.

Information about shielding the CAN bus
In order for the CAN bus to operate faultlessly, you have to connect the
shielding using one of the following variants. If you are not able to use any of
the variants detailed below, we recommend using fiber-optic cables. Fiber-
optic cables decouple the devices and are not sensitive to electromagnetic
interference (surge and burst).
NOTICE
Damage to the device!
If you connect the CAN bus cable to devices with different potentials, cur-
rent may flow across the shielding. This current may damage the device.
►Connect the devices to a potential equalization rail to equalize the poten-
tial.
►If both devices have different potentials, only connect the CAN bus cable
shielding to one device.
Variant 1: The connected devices share the same potential
If the devices to be connected share the same potential, proceed as follows:
1. Connect all devices to a potential equalization rail to equalize the poten-
tial.
2. Connect the CAN bus cable shielding to all connected devices.
Variant 2: The connected devices have different potential levels
Note that the shielding is less effective with this variant.
If the devices to be connected have different potential levels, proceed as fol-
lows:
►Connect the CAN bus cable shielding to just one device.

screening in the motor-drive unit on the grounding bar. The cable shielding
should only be removed just prior to connecting, to ensure that the section
with unshielded cables is kept as short as possible. The shielding must be
connected with shielding clips.

6.5 Connecting the motor-drive unit
WARNING
Danger of death or severe injury!
An energized transformer and energized on-load tap-changer components
could cause death or serious injuries when installing the electrics!
►Adherence to the following safety precautions is mandatory.
The drive may only be connected to circuits that are equipped with an exter-
nal and all-pole isolating device as close to the drive as possible to ensure
that the unit can be fully de-energized if required (service, maintenance etc.).
Furthermore, a drive without its own overcurrent protective device for the
control circuit and the heater circuit may only be connected to circuits that
are equipped with an external overcurrent protective device. The protective
device must ensure protection against indirect touching. The protection rec-
ommended by Maschinenfabrik Reinhausen GmbH close to the drive is 1.6
A C (3.0 A C is to be used in a heater circuit with additional heating and sup-
ply voltage <127 V AC/DC). This is to be verified after installation by carrying
out a measurement.
Maschinenfabrik Reinhausen GmbH 2020

6385142/08 EN
ETOS® ED
Suitable equipment includes isolating devices in accordance with IEC
60947-1 and IEC60947-3 (e.g. circuit breaker). When selecting the circuit
breaker type, the properties of the relevant circuits (voltage, maximum cur-
rents) must be observed. The following should also be noted during installa-
tion:
▪ It must be easy for the operator to access the isolating device
▪ The isolating device must be labeled for the device and circuits to be iso-
lated
▪ The isolating device may not be a part of the power line
▪ The isolating device may not interrupt the main protective conductor
Unless specified otherwise, the connections for the supply circuits must have
a conductor cross-section of at least 2.5 mm2 (16 AWG). Check applicable
standards and directives to ensure that the specified minimum cross-section
of the supply line is sufficient.
6.5.1 Cable recommendation
NOTICE
Damage to the device.
Current flow through the shielding of signal lines can cause the device to
become damaged.
►For signal lines between the motor-drive unit and transformer, connect
the shielding of the signal line to the motor-drive unit only.
►For all other signal lines, connect the shielding on both sides as long as
there is no potential difference between the two devices. If there is a po-
tential difference, then connect the shielding on one side only even when
using these signal lines.
Please note the following Maschinenfabrik Reinhausen GmbH recommenda-
tion when wiring.
▪ Electromagnetic interference on signal lines, which can be expected due
to the transformer's surroundings, can disrupt the proper operation of the
motor-drive unit.
▪ Where possible, route signal lines with shielding.
▪ Ensure that the copper cables used have a temperature resistance of
70°C.

components fitted in the motor-drive unit.
7.4 Transporting transformer to the operating site
If the drive must be removed in order to transport the transformer, proceed
as follows:
1. Ensure that the drive and the on-load tap-changer are in the adjustment
position.
2. Remove the drive.
3. Do not actuate the drive while the on-load tap-changer is uncoupled and
do not turn the output shaft.
4. Do not actuate an on-load tap-changer which is uncoupled and do not turn
its drive shaft.
5. Transport the drive to the installation site in the MR delivery packaging.
6. Fit drive and drive shaft to transformer at the installation site.
7.5 Commissioning the transformer at the operating site

NOTICE
Damage to the on-load tap-changer and motor-drive unit!
Damage to on-load tap-changer and motor-drive unit due to incorrect use of
position transmitter equipment.
►Only circuits stated in the chapter Technical data for position transmitter
equipment [►Section 14.3, Page 380] may be connected to the position
transmitter module connections.
►The switchover point of the position transmitter equipment in the motor-
drive unit is not the same as the switchover point of the diverter switch
operation. This depends on the type of diverter switch. This fact should
be noted when project planning the locking circuits between the motor-
drive unit and external equipment (e.g. transformer circuit breaker).
►Therefore, the "Tap changer in operation" position transit contact shown
in the connection diagram should be used for external monitoring, locking
and control purposes instead of the position transmitter equipment.
1. Commission motor-drive unit [►Section 7.1, Page 89].
2. Ensure correct function of motor-drive unit [►Section 7.2, Page 90].
3. Commission the transformer.

7.6.5 Checking measured values and status of digital inputs and
outputs
Upon commissioning the device, check whether the measured values and
status of digital inputs and outputs are plausible. To do so, use an additional
measuring device if necessary in order to check the individual measured val-
ues.
To display the status of the digital inputs and outputs, proceed as follows:
1. Go to Information > Hardware.
2. Select the individual assemblies one after another and check the individ-
ual measured values or the status of digital inputs and outputs.
3. If errors arise, check the measurement path and the wiring.
7.6.6 Checking the temperature measurement
To commission the device, check whether the measured temperatures are
plausible, the temperature sensors are correctly wired and are assigned to
the desired functions. To do so, proceed as follows:
1. Display the temperature curve [►Section 9.24.4, Page 253].
2. Use a suitable measuring instrument to measure the temperatures at the
measurement points and compare these values to the displayed tempera-
tures.
ð The temperatures must match, though small deviations are permitted
due to the measurement tolerances.
