Model Description:
The Horizon Models 642VES, 642VFD, and 642VFD-Plus are continuous-duty, electronically
controlled, variable-speed, laboratory centrifuges equipped with a lid safety interlock system.
They offer the user control over many parameters, including variable runtime, speed control, and
deceleration. The exclusive horizontal rotor allows for quick and easy sample loading and complete
horizontal separation. Samples can be viewed safely through the transparent lid. Entry into the
centrifuge is restricted during operation by the safety interlock system.
The centrifuge is controlled in the following manner depending on the model:
642VES:
Controlled by five electronic push buttons and a backlit display, for easily controlling
centrifugation parameters. Up to nine commonly used settings can be saved and recalled at
the touch of a button.
642VFD-Plus:Controlled by two electronic push-button timers that have been preset for ten (10)
minutes at 3,800 RPM and five (5) minutes at 1,800 RPM, for precise spin times and
ease of use.
642VFD:
Controlled by one electronic push-button timer that has been preset for ten (10)
minutes at 3,800 RPM, for precise spin times and ease of use.

Safety:
Lid Safety Switch:
The lid is secured to the top of the cabinet by a latching knob and pawl system. When the knob is
rotated clockwise, the pawl grips the underside of the cabinet opening and prevents the lid from
opening. A mechanical stop positions the pawl and prevents it from rotating completely. When
rotated to the stop position, the pawl makes contact with a micro–switch mounted underneath the
cabinet top. The lid safety switch prevents the centrifuge from operating while the lid is open. An
indicator light on the front of the machine will light up when the lid has been latched properly.
Lid Safety Interlock System:
In addition to the Lid Safety Switch, the 642VFD, 642VFD-Plus, and 642VES has a true “0 RPM”
lid locking system. The lid safety interlock system keeps the lid locked at all times, (even during
power failure), and requires that the rotor be at rest in order to unlock the lid. The centrifuge will
not allow entry into the rotor chamber unless the centrifuge has power and the rotor is stopped.
To open the lid, make sure that the centrifuge is plugged in and, with the rotor stopped, press the
OPEN/STOP button.
Note: After the centrifuge has started spinning, it may be possible to rotate the lid
knob enough to cause the pawl to lose contact with the lid safety switch. If this
happens, the centrifuge motor may lose power, but the lid will still remain locked. If
the knob is accidentally moved and this situation should occur, rotate the knob fully
clockwise to its stop position and the centrifuge will resume operation.
4A Resettable Circuit Breaker
The 642VFD, 642VFD-Plus, and 642VES is protected with two in-line 4A resettable circuit
breakers on the underside of the device. Any electrical overcurrent will trip the breakers, cutting
power to the machine and protecting the internal electronics
Emergency Rotor Chamber Entry:
In the event of power failure, it may be impossible to unlock the lid by conventional means. In this
case, entry into the rotor chamber may be made by removing the latch label and using a pen to
manually disengage the locking mechanism (see photo). Pull the mechanism towards the control
panel and then unlatch and open the lid. If the unit is damaged, contact your authorized dealer or
Drucker Diagnostics.
Transportation
During transportation accessories can become dislodged from the rotor and fall into the
rotor chamber where they can remain unnoticed. In the event that the centrifuge needs to be
transported to another site, make certain that there are no tube holders or accessories in the rotor
or rotor chamber.
Repaired Units
For verification of the safe state of the centrifuge following factory service or repair, refer to the
date on the Factory Calibration located on the back of the centrifuge. This is the date that the
repaired centrifuge was last factory tested and calibrated. For additional servicing information and
technical support, contact Drucker Diagnostics or your authorized retailer.
Calibration and Earth Ground Testing:
It is recommended that the top speed, ground continuity and line leakage be tested every two
years for continued safe operation. Contact Drucker Diagnostics for further information or testing
availability.

Setup Location:
1. Unpack the centrifuge and verify that all of the supplied equipment is present.
2. Choose a setup location which meets the following criteria:
a) A bench top clearance height of 20” is required in order to open the lid.
b) The clearance envelope is the space around the centrifuge which is required for safety.
Choose a setup location which will allow for a clearance envelope of at least 24” x 24”,
(with the centrifuge at the center). Do not position the centrifuge in such a way
that it would be difficult to disconnect the power in the case of emergency. No person
or hazardous material shall be permitted in the clearance envelope during operation. The
operator time within the envelope shall be limited to the time necessary for loading,
unloading and centrifuge operation only.
c) Proper ventilation is necessary to prevent the overheating of samples as well as
premature failure of the centrifuge. Choose an area which will allow unencumbered air
flow.
d) The centrifuge is designed to secure to the operating surface by four suction feet. No
adjustment is necessary for leveling the centrifuge, however, the surface should be flat
and level.
e) Be sure the outlet is always within reach as the line cord is the means of
emergency disconnection!
Initial Setup Procedure:
If any problems are found during the initial setup procedure, refer to the troubleshooting
section on page 9.
1. Plug the female end of the supplied line cord into the power input module located on the
rear of the centrifuge. Plug the male end into an approved
electrical outlet. For electrical safety, the unit must always be
properly grounded.
2. Flip the switch on the power input module located on the rear of
the centrifuge to the ON ( | ) position.
3. For safety purposes, the locking system is always activated.
To deactivate the system, (in order to insert or retrieve
samples), press the OPEN/STOP button on the
control panel. The UNLOCKED indicator light should illuminate. If it does not,
refer to page 9 on troubleshooting. The lid will be unlocked for 15 seconds after pushing
the OPEN/STOP button.
4. Turn the latch counterclockwise and open the lid.
5. Spin the rotor by hand; check for free and level rotation. If the rotor does not spin freely,
refer to page 9 on troubleshooting.
6. Place the six test tube holders inside the rotor (as shown to the right), and verify that
they are seated properly.
7. Close the lid. Rotate the lid knob clockwise to its complete stop position. The ’LATCHED’
indicator light should be illuminated. If it is not, make sure that the lid is latched properly.
The centrifuge will not run unless the lid is latched and the ‘LATCHED’ light is
illuminated.
8. Start a centrifugation cycle by pushing the START (BLOOD) button.
9. The ‘RUNNING’ indicator light will illuminate.
10.The test tube holders will slide up into the horizontal position and the unit will accelerate
to full speed.
11.Listen to the sound of the centrifuge. A smooth whirring sound should be heard. If
there are any loud or unusual sounds, stop the centrifuge by pushing the OPEN/STOP
button immediately and refer to page 9 on troubleshooting.
12.Push the OPEN/STOP button. The ‘RUNNING’ indicator light should go out and the
motor should slow to a stop.
12.The lid should remain locked until the rotor has nearly stopped. If the machine unlocks
prematurely, contact Drucker Diagnostics for assistance. Once the rotor has stopped, the
interlock system will become disengaged for sixty (60) seconds. The ‘UNLOCKED’
indicator light will illuminate during this time.
13.To gain entry into the centrifuge after this period has ended, simply press the OPEN/
STOP button. The lid will unlock for fifteen (15) additional seconds.
After the centrifuge has passed this procedure it is ready for operation.

– Check the circuit breaker switch at the bottom left of the machine. If the switch is white, the breaker has tripped.
Contact Drucker Diagnostics for further assistance.
– The printed circuit board may be damaged. Have a technician test and replace the circuit board if necessary.
Problem:
The latch light does not come on when the lid is closed.
Solutions:
– Make sure that the unit has power.
– Make sure the lid latch is turned completely clockwise to its stop position. The latch makes contact with a switch
underneath the front top of the cabinet. If this switch is not activated, the light will not turn on and the machine will
not run.
Problem:
The machine does not unlock after a run has completed.
Solutions:
– The lid should remained locked until the rotor has nearly come to a complete stop and then unlock for 60 seconds.
If additional unlock time is needed, press the ’OPEN / STOP’ button with the machine plugged in and the
rotor stopped. If the lid remains locked after this and will not unlock, the electronics may have been
damaged. Contact Drucker Diagnostics for assistance. To access the rotor chamber, follow the procedure on
page 10,“Emergency Rotor Chamber Entry”.
Troubleshooting:
NOTE:
The lid latch must be turned completely
clockwise to its stop position in order for
the centrifuge to operate.

Problem:
Problem:
The yellow and green LED indicators are blinking with 4 short audible beeps repeating continuously. (VES will display ‘Motor Error’)
The centrifuge cycle stops prematurely and the yellow LED indicator is blinking.
Solutions:
Solutions:
- The internal tachometer has either not sensed a speed, the sensed speed is out of range, or the wrong rotor is installed.
(NOTE: if the wrong rotor is installed the centrifuge will not run without reprogramming the rotor selection)
- Verify that the rotor being used is programmed correctly in the settings. Reprogram the correct rotor selection if
necessary. Refer to page 7 for instructions.
- Remove the rotor following the instructions on page 7. Check to see that there is a small silver reflective sticker on the
exterior vertical wall of the rotor.
- If the reflective sticker is present on the rotor and the correct rotor is programmed in the settings, contact Drucker
Diagnostics for further assistance.
For servicing information or additional technical support,
contact Drucker Diagnostics or your authorized distributor.
Problem:
Problem:
All LED indicators are blinking with 2 short audible beeps repeating continuously.(VES will display ‘Imbalance Error’)
The yellow and red LED indicators are blinking with 3 short audible beeps repeating continuously. (VES will display ‘Motor Power Err’)
Solutions:
Solutions:
- The imbalance detection threshold has been reached during the cycle indicating a full cycle was not completed.
- Check the balance of the load. Refer to BALANCED LOADS on page 7.
- If it is determined that the detection is too sensitive this can be adjusted by increasing the imbalance detection
threshold. Refer to page 6 for programming settings.
- The electrical current to the motor has exceeded the allowable limit, indicating that the full cycle was not completed.
- Make sure that nothing has fallen into the rotor chamber preventing the rotor from spinning freely.
- If there is nothing obstructing the rotor, the motor may be damaged. Contact Drucker Diagnostics for further assistance.
- This is an indication that the lid is not properly latched and the cycle has entered the “paused” state.
- Turn the knob clockwise to re-latch the lid and resume the cycle.
- If the cycle does not resume and the knob is fully turned, contact Drucker Diagnostics for further assistance.
Problem:
The run time is not set to the desired length.
Solutions:
