Motor Overheat
The Motor Overheat function is only available for TeSys avatars whose Temperature Sensor Available parameter is activated. These avatars include an analog I/O module, which is wired to the temperature input from the temperature sensor associated with the protected motor.
If enabled, this protection function performs the following:
-
Signals a Motor Overheat Alarm when the motor temperature exceeds the Motor Overheat Alarm Level
-
Triggers a Motor Overheat Trip when the motor temperature exceeds the Motor Overheat Trip Level, for a time longer than the Motor Overheat Trip Delay
The Motor Overheat Trip Reset Threshold parameter sets the percentage below which the temperature must fall, before a trip reset is allowed.
