ROUBLESHOOTING
________________________________
The ThermoRack 800 has four system alarms that when triggered
will show on the display. When an alarm is displayed the system
will not attempt to heat or cool the coolant, except under tank level
low alarm.
Alarms:
Tank Level Low: Liquid reservoir level is too low. This is a
warning and the unit will continue to control temperature under this
condition.
Unless filling for the first time, check all outside
plumbing lines for leaks. Once all leaks are sealed, remove the cap
and add more coolant until the alarm disappears.
RTD Open: The temperature sensor has failed. Temperature control
will stop.
Turn off the chiller and disconnect the AC power cord.
Contact SSCS for an RMA number to return the unit for RTD
replacement.
Fan Fail: The ThermoRack 800 checks fan operation at startup. Fan
fail indicates the fan is supplying insufficient air to cool the
thermoelectric devices.
Either the fan has failed or the airflow into
or out of the system is blocked. Check that the front and rear air
inlet and outlet gratings are not blocked. If airflow is not blocked,
contact SSCS for an RMA number to return the unit for fan
replacement.
Pump Fail: The liquid heat exchanger plate temperature is either
too hot or too cold, indicating a pump failure or a blockage in the
external plumbing lines. Temperature control will stop.
Turn off the
chiller and disconnect the AC power cord. Verify that no kinks or
blockages exist in external plumbing line. If no coolant flow
blockages exist, contact SSCS for a RMA number to return the unit
for pump replacement.
Other issues:
No Display: If the liquid crystal display does not display characters
upon turning on the Thermorack 800,
call SSCS for a RMA number
to return the unit for replacement of the temperature controller
Temperature Control Poor: If no other alarms are present, poor
temperature control can indicate blocked airflow or that the TE
cooling/heating engine is not receiving power or has failed. If the
chiller cools but cannot reach the set point, and the displayed
temperature is higher than the set point, the heat load may be too
great for the chiller,
Contact SSCS for technical support.
Important:
The tank level low alarm will automatically reset when
the tank is filled. The RTD, Fan and Pump failure alarms will not
reset until the system power is turned off.
Do not remove cover or
attempt to repair unit,
as electrical shock
hazards exist inside
