SYSTEM ALARMS/TROUBLESHOOTING _______________________________
The ThermoCube II has multiple 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.
Alarms:
Tank Level Low: Liquid reservoir level is too low. 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 Fault: The temperature sensor has failed or its connector has
come loose. Turn off the chiller and disconnect the AC power cord.
Contact SSCS for a replacement RTD, or for a RMA number to return
the unit for RTD replacement.
Fan Fail: Fan is supplying insufficient air to cool the thermoelectric
heat exchanger. Either the fan has failed or the airflow into or out of
the system is blocked. Check that the side air inlet and outlet gratings
are not blocked. The ThermoCube II requires at least 3 inches of
clearance around these gratings. If airflow is not blocked, contact
SSCS for a replacement fan, or for a RMA number to return the unit
for fan replacement
Flow FLT/CHK Lines: The coolant flow rate has dropped below
0.7lpm on the internal flowmeter indicating pump failure, a blockage
in the external plumbing lines (-FM Flowmeter Option only) Verify
that no kinks or blockages exist in the plumbing line outside of the
ThermoCube. If no coolant flow blockages exist, contact SSCS for a
replacement pump, or for a RMA number to return the unit for pump
replacement.
Pump Fault: The liquid heat exchanger plate temperature is either too
hot or too cold, indicating pump failure, a blockage in the external
plumbing lines or operation outside the normal 5°C to 50°C coolant
temperature (without –LT or –HT options). Verify that no kinks or
blockages exist in the plumbing line outside of the ThermoCube. If
no coolant flow blockages exist, contact SSCS for a replacement
pump, or for a RMA number to return the unit for pump replacement.
No Display: If the liquid crystal display does not illuminate upon
turning on the ThermoCube II, the internal 24VDC power supply has
failed, the diaphragm pump has failed, or the LCD display has failed.
Contact SSCS for a RMA number to return the unit for replacement
of the power supply, diaphragm pump, or display.
Temperature Control Poor: If no other alarms are present, poor
temperature control indicates the heat load is too great for the chiller,
the TE cooling/heating engine is not receiving power, the PID
constants have been corrupted or the chiller needs repair. Otherwise,
contact SSCS for technical support.
