Troubleshooting Guide for uTC-15 & uATC-15a

Problem	Possible Solution
The module will not turn on.	Check power cord and input power. Is main frame turned on? Check fuses (ABC-15), if blown, check for wiring short.
The module falsely indicates open thermocouple.	Check thermocouple input fuses.
The module falsely indicates thermocouple shorted.	Check "toH" time setting.
Module appears to operate properly, but no power is passing through the heaters.	Main frame is not set for Anti-Arching feature. Move jumper from pin position #2 & #3 (enabled) to pi position #1 & #2 (disabled.
Mold is unusually cold.	Allow mold to warm up in Soft Start mode. Check mold thermocouple wiring Make sure input power voltage is correct
Mold Overheats.	Is temperature display set to ° F scale? Check thermocouple Replace triac
Open thermocouple.	Check mold wiring
Module blows fuses.	Make sure heater size does not exceed module rating. Make sure this is not the result of a shorted heater or a short in the mold wiring. Do not replace module until problem is corrected or damage can result.
If problems are experienced with the control module, we recommend you return it to International Temperature Control Inc. for repair or calibration. Top

Other False Alarms

You may experience false alarms due to the time settings of certain options. The factory settings may not the proper setting for your particular zone characteristics.
For zones that heat slowly you may need to extend the time for open heater and shorted thermocouple detection (toH). Conversely you may want to decrease time for zones that heat too fast.
If you are in a situation where mold changes are frequent and you do not want to take the time to adjust these settings to the mold characteristics, you can set all the settings to the higher level or in some cases turn them off. However, this will substantially reduce the control module's many diagnostic benefits and its ability to prevent heater runaway and mold damage.
If an instrument is not functioning properly or need calibration, we highly recommend that you return it to ITC for repair or calibration. In most cases your module will not be correctly repaired or calibrated at other facilities.
