Alarming

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
