What to do if the Green LED is OFF (TD1) or all LEDs are OFF (TD2) on my Magnetrol Thermatel TD1 Switch?
If the green LED is off (TD1) or all LEDs are off (TD2) on your Magnetrol switch, it could be due to a lack of power. First, verify the power supply. Then, check the wiring at the wiring terminals to ensure everything is properly connected.
Why is the Red LED blinking and showing ?3,6 mA or ?22 mA (TD2) on my Magnetrol Thermatel TD1 Switch?
A blinking red LED accompanied by a reading of ?3,6 mA or ?22 mA (TD2) on your Magnetrol switch indicates that an instrument error has been registered. Try changing the switch settings, as this may return the unit to normal operation. If the problem persists, you should consult the factory.
How to fix a Magnetrol Thermatel TD1 when the Red LED does not turn ON?
If the red LED on your Magnetrol switch isn't turning on, it's possible that the switch point cannot be established for air flow detection. Ensure that the probe is extended into the flow. You might also need to change the Heater setting to “-”.
What to do if the Magnetrol Switch indicates a fault and the red LED is blinking?
If the red LED on your Magnetrol Switch is blinking, indicating a fault, the solution depends on the cause: * **Liquid Level – Sensor Wet:** First, verify that HEATER (TD1) / HTR (TD2) is set to “–”. Then, change HEATER/HTR to “+”. If the light goes off, operate in this mode. If the light stays on, check resistance to determine if a problem exists with the probe or electronics; the probe and/or electronics may need to be replaced. * **Liquid Level – Sensor Dry:** Verify that HEATER (TD1) / HTR (TD2) is set to “–”. Turn off FAULT (TD1) / FLT (TD2). If the light goes off, operate in this mode. If the light stays on, check resistance to determine if a problem exists with the probe or electronics; the probe and/or electronics may need to be replaced. * **Liquid Flow – Sensor Dry or No A...
