What to do if TECSYSTEM Temperature Controller channel indicates FOC/FCC fault?
If one of the four channels on your TECSYSTEM Temperature Controller displays an FOC/FCC fault, first check the sensor connections to ensure they are properly connected. Next, inspect the sensors for any signs of damage. If a sensor is damaged, replace it.
How to troubleshoot TECSYSTEM Temperature Controller that won't switch on?
If your TECSYSTEM Temperature Controller does not switch on even with control power supplied, verify the terminal block for correct installation. Also, check for the presence of voltage at the terminal block.
Why is TECSYSTEM Temperature Controller showing wrong temperature?
If the temperature displayed by one or more channels on your TECSYSTEM Temperature Controller is incorrect, it could be due to defective sensors. Check the sensor resistance using an Ohm-meter. If the sensors are not the issue, the unit may be incorrectly calibrated and should be returned for repair.
Why do alarm and trip relays energize when switching TECSYSTEM Temperature Controller on/off?
The alarm and trip relays may energize when switching your TECSYSTEM Temperature Controller on or off because strong electrical noise is being picked up on the power line. To resolve this, ensure the shield of the sensor cable is connected to the panel ground. Additionally, consider installing shielded cable (Mod. CT-ES) or twisting the sensor conductors.
What causes sudden trip relay activation in TECSYSTEM Temperature Controller?
Sudden activation of the trip relay in your TECSYSTEM Temperature Controller, especially when operating temperatures are normal, and one channel is the cause, is likely due to a defective sensor (Fcd). Replace the sensor to resolve this issue.
Why does TECSYSTEM Temperature Controller display FCC on all sensors?
If your TECSYSTEM Temperature Controller shows FCC on all sensors, it is probably caused by wrong wiring connections. Specifically, the terminal block is likely upside-down. Check the terminal block.
