Loop disconnection detection function and heater disconnection detection function of temperature control module

How do I use loop disconnection detection function and heater disconnection detection function of the temperature control module L60TCTT4BW?
Category : 

Answer

The heater disconnection detection function monitors the heater current on the transistor output.
If no current flows when the transistor is ON, it is considered as disconnection.
The loop disconnection detection function monitors a series of processing from temperature input to temperature output.
If the temperature change in the specified time (default 8 minutes) is less than 2°C, the function detects the situation as a possible disconnection.
