The Georg Fischer EA25-250 actuator monitor board plugs into EA25, EA45, EA120 & EA250 electric actuators to provide four monitoring functions:
Cycle time extension
The cycle time extension extends the cycle time of the electric actuator. To do this, the actuator is moved continuously into the end positions (OPEN or CLOSE). For the corresponding value please refer to the table below. These values are valid for 90° actuation. The cycle time is given in seconds.
Cycle time monitoring
The cycle time monitoring monitors the duration of a preset cycle time of the electric actuator. As soon as the cycle exceeds the preset time, an error is reported. For the corresponding value please refer to the table below. These values are valid for 90° actuation. The cycle time is given in seconds.
This function allows setting a desired number of cycles. As soon as the number of cycles exceeds the set value, an error is reported.
Motor current monitoring
The current monitoring function monitors the motor current. If the motor current is higher than the preset value, an error is reported and the actuator will remain in place.
