| Symptom | Likely Cause (from manual) | Solution | | :--- | :--- | :--- | | | Broken thermocouple or RTD wire. | Check continuity of sensor. Replace sensor. | | Controller heats continuously | Output relay fused closed or SSr shorted. | Disconnect output wire; if heat stops, replace SSR. | | Cannot change Setpoint | Parameter lock is active ( LOC = 1). | Enter config menu, find LOC , set to 0 . | | Reading is erratic | Electromagnetic interference (EMI). | Separate input wires from power wires (see manual wiring diagram). | | Display stays at 0 | Input configuration wrong (e.g., set for TC but using PT100). | Change InP parameter to match sensor type. |
The 25050 supports up to 3 alarms. The manual details each mode:
