- Page 2 Product Description The TRM Series EL-TC 14X electronic temperature controllers are designed for monitoring and control of heating and heat tracing circuits. The temperature controller comes complete with a single circuit 20A switching output and additional 8A alarm relay. The controller is designed to operate with 3-wire or 2-wire Pt100 RTD temperature sensors (optionally supplied by TRM).
- Page 3 Operational Description The controller (via relay K1) will automatically switch the heating circuit ON when the actual temperature (P01) falls below the control temperature setpoint (P10 minus hysteresis P11). In the event of an error condition, the integrated alarm relay (K2) switches (via the SPDT contact, configurable as either NC or NO) to indicate one or all of the following error conditions: over / under temperature sensor-interrupt...

Error Messages When an error condition occurs, the display will indicate the error code after an approx. 20 second delay. Error Code Messages RTD/Pt100 temp sensor short circuit or temperature below -76°F (-60°C) RTD/Pt100 temp sensor interrupt (open) or temperature above 770°F (410°C) Temp.

Switching hysteresis from set point (P10) range 2..10K [2K] P12 .. Min. Relay Idle Time (Relay K1) 0..30.0 Min., [0.0 Min], resolution 0.1 min.
- Page 6 Releasing Relay Mode In this mode (when P34 = 2) relay K2 switches independently from alarm delay timers (P32 and P33) when the actual high/low temp threshold ranges are between high and low set points P30 and P31. Alarm Relay Modes (P34 = 0 or 1): If, after initial power on, the actual temperature falls below the low temp alarm threshold (P31), the alarm delay (P33) is used as the alarm relay to provide additional time for warm-up.
