Alarm

The following alarm conditions are continuously monitored by the temperature controller:
- Absolute temperatures (high and low)
 - Relative temperatures (in two bands around the setpoint)
 
The following hardware conditions related to the sensor can also be linked to the temperature controller:
- Open thermocouple: broken wire to the temperature sensor.
 - Back voltage: a voltage outside the permitted range is present at the temperature sensor.
 - Reverse thermocouple: temperature sensor is connected with the wrong polarity.
 
If a current sensor is connected, then the following signals can be linked to the temperature controller:
- Short circuit
 - open circuit
 - Leakage current
