4.1 Function
Series 8146/5041 is a temperature controller and limiter with a liquid-filled measuring
system. The change-over contact is activated due to temperature related volume
changes. In case of leakage of the measuring system, the temperature controller
switches off permanently.
Temperature controller:
If the temperature of the sensor exceeds the set value, the controller switches off. If the
temperature falls below the set value, the controller switches on automatically.
Temperature limiter:
If the temperature of the sensor exceeds the set value, the limiter switches off
permanently. After the temperature has dropped, the temperature limiter can be unlocked
manually.
