ERROR CODES
The QX2 is programmed to identify certain problems in the proper function of the
system. If one of these problems occurs, the system will shut down and one of the
following error codes will appear on the controller display. The system must be
turned off to reset the error message.
“Int Temp Error” The internal temperature of the power supply is too high and
may damage the electronic circuitry. If this error occurs
repeatedly, the QX2 should be moved to a cooler location.
“Overtemp Error” The temperature of the heater is too high. Contact Metcal
Technical Services if this error occurs repeatedly.
“Heater Error” The controller has not detected a temperature from the heater,
indicating a broken heater or thermocouple.
“Control Timeout” The power supply and controller have been out of
communication for too long. This error will occur if you
unplug the controller cable while the system is on.
“Comm Error” The power supply or controller got a signal that it did not understand.
If it happens repeatedly, contact Metcal Technical Services.
