The technical data are not binding and not expressly
warranted characteristics of the goods. They are

Using the monitoring, the instruction manual of the electric
actuator type EA 25-250 must be observed.
Intended use
Accessory board Monitoring
The monitoring can be used with the electric actuators type EA25, EA45, EA120
and EA250, both with the 24V AC/DC as well as the 100-230V AC version. The
board is to be plugged into the housing of the actuator in the provided slots.
1Function
The monitoring enables four functions: Cycle time extension, Cycle time
monitoring, Cycle counter and Motor current monitoring.
Via the BCD switches 1 to 4 the
monitor settings are made. The
different functions work
independently of one another.
Cycle counter
Monitoring a selected maximum number of cycles
Motor current monitoring
Monitoring a selected maximum motor current
2Assembly of the monitoring board
Disconnect the actuator from the supply voltage.
1. Remove housing cover of the electric actuator (loosen the 4 screws, open
cover).
2. Take the monitoring board out of the packaging and check for damages.
Do not touch the board itself. Electrostatic discharge can damage the
components.
3. Insert board vertical on the backside of the main board onto the red plug.
Ensure that the board sits in the lateral guides and snaps.
4. Make desired settings according to 3 “Settings“.
5. Stick scheme label into housing cover.
6. Put the cover back in place and fasten it with the 4 screws.
3Settings
1. 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.
2. 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 pre-set 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.
