characteristics of the goods. They are subject to change. Our General
Conditions of Sale apply.
Using the monitoring, the instruction manual of the electric actuator type
EA 25-250 must be observed.
Intended use
Accessory board Fail-safe return unit
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. The fail-safe return unit already includes the required
battery; no external wiring is necessary. The board is also available
without a battery for connecting an emergency external power source
with 24 V DC.

Function
In case of a failure of the supply voltage, the battery is electronically
switched on automatically after 5 s. With the selector switch on the board,
the functions "Move to CLOSE position" or "Move to OPEN position" can
be selected.

The batteries are always stored charged. If the battery charges level
drops below 50 %, the actuator LED flashes yellow and the charge cycle
starts. Once U

During the charge cycle, the actuator can be operated normally. When
charging the internal Error LED displays “L”. The ready to operate signal
stays.

Assembly of the fail-safe return unit board
The push button on the right side of the PCB is used to check the charge
status of the batteries. If status is “ok” the LED on the PCB will light up
green after pressing this button. If no green light occurs do not use this
PCB.

Test functioning of the fail-safe return unit
Apply power to the actuator and move into position OPEN. Remove power
to the actuator. Actuator moves after about 5s to CLOSE position (or
reversed, depending on the setting of the switch).
4.
Put the cover back in place and fasten it with the 4 screws.

Error message
An error can triggers the following:
•
The 7-segment display on the main board illuminates; see illustration
below.
•
The ready-to-operate signal will be off (terminals 5,6 NO contact)
•
LED flashes yellow (except in case of power outage)
Assignment of error codes for error messages
If the fail-safe return unit PCB is installed, the following error codes can
be displayed:
