Check the seal to make sure it fits securely. 3. Click the fixing elements back into place and tighten the clamping screws by hand. Then use a screwdriver to tighten them another half a turn. CAUTION! The torque should not exceed 0.1 Nm! 1. Brief description The panel instrument M1-1C6 is a 4-digit device for temperature metering via Pt1000- sensors and a visual limit value monitoring via the display. The configuration happens via three front keys or via the optional PC-software PM-TOOL. An integrated programming interlock prevents unrequested changes of the parameter and can be unlocked again via an individual code. The electrical connection happens on the rear side via plug-in terminals. Selectable functions like e.g. the recall of the min/max-value, an impedance matching and a direct change of the limit value in operating mode complete the modern device concept.

Devices with a supply of 230 VAC need to connect terminal 3 to signal ground. 1 2 3 4 5 Pt1000 2-wire N L 230 VAC 3 VA <_ 1 2 3 4 5 Pt1000 2-wire _ + 24 VDC <_ 1 VA

3 4. Function description and operation 4.1. Programming via configuration software PM-TOOL-MUSB4: You receive the software on CD incl. an USB-cable with a device adapter. The connection happens via a 4-pole micromatch connector plug on the back and the PC is connected via an USB connector plug. System requirements: PC with USB interface Software: Windows XP, Windows Vista With this tool the device configuration can be created, skipped and saved on the PC. Via the easy to handle program surface the parameter can be changed, whereat the mode of operation and the possible selection options can be preset via the program. CAUTION! During parameterisation with connected measuring signal, make sure that the measuring signal has no mass supply to the programming plug. The programming adapter is galvanic not isolated and directly connected with the PC. Via polarity of the input signal, a current can discharge via the adapter and destroy the device as well as other connected components! Level Button Description Menu level Change to parameterisation level with the relevant parameters. For navigation at the menu level. Parameterisation level To confirm the changes made at the parameterisation level. To change the value or setting. Operation The operation is divided into two different levels. Menu Level Here it is possible to navigate between the individual menu items. Parameterization level: The parameters stored in the menu item can be parameterized here. Functions that can be adjusted or changed, are always indicated with a flashing of the display. Adjustments made at the parameterisation level should always be confirmed by pressing the [P]-key to save them. However, the display automatically saves all adjustments and then switches into operation mode if no further keys are pressed within 10 seconds.

Once the installation is complete, start the device by applying the current loop. Check beforehand once again that all the electrical connections are correct. Starting sequence For 1 second during the switching-on process, the segment test ( ) is displayed, followed by an indication of the software type and, after that, also for 1 second, the software version. After the start-up sequence, the device switches to operation/display mode. 5.2. Standard parameterization: To be able to parameterize the display, press the [P] key in operating mode for 1 second. The display then changes to the menu level with the first menu item . 5. Setting up the device 5. Setting up the device Menu level Parameterization level Type of the temperature measurement, Default: For representing of temperature choose between °C and °F and confirm with [P]. The display then switches back to the menu level again. Setting the decimal place / sign of physical unit, : Default: The decimal place and the physical unit are set with [▼] [▲]. If e.g. the temperature measurement is chosen in °C, 0°C or 0.0°C can be selected on the parameterization level. Confirm with [P], the display then switches back to the menu level again. Impedance matching, : Default: The value for the sensor alignment is adjusted from the smallest to the highest place with [▼] [▲] and confirmed digit per digit with [P]. After the last place the display switches back to the menu level. The value alignment for a temperature measurement in °C can be set between -20.0 and +20.0 and for a measurement in °F between -36.0 and +36.0. If the measurement is redirected later, the value is rounded.

Menu level Parameterization level Setting the display time, : Default: The display time is set with [▲] [▼]. The display moves up in increments of 0.1 sec up to 1 second and in increments of 1.0 to 10.0 seconds. Confirm the selection by pressing the [P] button. The display then switches back to the menu level again. 5.3. Programming interlock Activation / deactivation of the programming lock and completion of the standard parameterization, Default: Choose between the deactivated key lock (works setting) and the activated key lock with the navigation keys [▲] [▼].

Menu level Parameterization level Min/max-value inquiry - assignment of key functions, Default: Here, you can enter for the operating mode either a min/max-value inquiry or a threshold value correction on the arrow keys. If the min/max-memory is activated with , the measured min/max-values will be saved during operation and can be called up via the arrow keys [▲] [▼]. When the device is restarted or the buttons are pressed simultaneously, the values are lost or deleted. If the threshold value correction is selected, the limit values can be changed during operation without hindering the operating procedure. If is parameterized, the navigation keys [▼] [▲] have no function in operating mode. Flashing of display, Default: Here, flashing of the display can be added as an extra alarm function, either to the first limit value (select: ), the second limit value (select: ) or to both limit values (select: ). With (works setting), no flashing is assigned at all. Limit values / limits, Default: For both limit values, two different values can be parameterized. With this, the parameters for each limit value are called up one after the other. Hysteresis for limit values, Default: For both limit values, a hysteresis function exists that reacts according to the functional principle (operating current / quiescent current). 5.4. Extended parameterization By pressing the [▲] & [▼] keys during standard parameterization for one second, the display switches to the extended parameterization mode. Operation is the same as in standard parameterization.

Menu level Parameterization level Function if display falls below / exceeds limit value, Default: To indicate if the value falls below the lower limit value, can be selected (LOW = lower limit value) and if it goes above the upper limit value, can be selected (HIGH = upper limit value). LOW corresponds to the quiescent current principle and HIGH to the operating current principle. Limit value / limits, Default: For both limit values, two different values can be parameterized. With this, the parameters for each limit value are called up one after the other. Hysteresis for limit values, Default: For both limit values, a hysteresis function exists that reacts according to the functional principle (operating current / quiescent current). Function if display falls below / exceeds limit value, Default: To indicate if the value falls below the lower limit value, can be selected (LOW = lower limit value) and if it goes above the upper limit value, can be selected (HIGH = upper limit value). LOW corresponds to the quiescent current principle and HIGH to the operating current principle. Setting the code, Default: Here, it is possible to select an individual code (works setting ) for locking the keyboard. To lock/release the key, proceed according to menu item .

keep it for future reference. Proper use The M1-1C6-device is designed for the evaluation and display of Pt1000 signals. Danger! Careless use or improper operation can result in personal injury and/or damage to the equipment. Control of the device The panel meters are checked before dispatch and sent out in perfect condition. Should there be any visible damage, we recommend close examination of the packaging. Please inform the supplier immediately of any damage. Installation The M1-1C6-device must be installed by a suitably qualified specialist (e.g. with a qualification in industrial electronics). 9. Safety advices Notes on installation • There must be no magnetic or electric fields in the vicinity of the device, e.g. due to transformers, mobile phones or electrostatic discharge. • The fuse rating of the supply voltage should not exceed a value of 0.5A N.B. fuse! • Do not install inductive consumers (relays, solenoid valves etc.) near the device and suppress any interference with the aid of RC spark extinguishing combinations or free- wheeling diodes. • Keep input, output and supply lines separate from each other and do not lay them parallel with each other. Position “go” and “return lines” next to one another. Where possible use twisted pair. So, the best measuring results can be received. • Screen off and twist sensor lines. Do not lay current-carrying lines in the vicinity. Connect the screening on one side on a suitable potential equaliser (normally signal ground). • The device is not suitable for installation in areas where there is a risk of explosion. • Any electrical connection deviating from the connection diagram can endanger human life and/or can destroy the equipment. • The terminal area of the devices is part of the service. Here electrostatic discharge needs to be avoided. Attention! High voltages can cause dangerous body currents. • Galvanic insulated potentials within one complex need to be placed on an appropriate point (normally earth or machines ground). So, a lower disturbance sensibility against impacted energy can be reached and dangerous potentials, that can occur on long lines or due to faulty wiring, can be avoided. 12 9. Safety advices
