Using the monitoring, the instruction manual of the electric actuator type EA15
must be observed.
Intended use
Accessory board Fail-safe return unit
The monitoring can be used with the electric actuators type EA15, 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.
Description Technical data
Fail-safe return unit With integrated battery pack
Fail-safe return unit Voltage supply implemented
external externally (24 V DC)
1 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.

Switch right (standard) Actuator moves to CLOSE (CW/clockwise)
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 rises above 50 %, the flashing stops.
Batt
During the charge cycle, the actuator can be operated normally. When
charging the internal Error LED displays "L". The ready to operate signal stays.

2 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.
CAUTION!
The board must not be plugged into the actuator while the green LED is
activated on the.PCB.
LED turns off after 30s, then the board is ready to be installed.
CAUTION!
Disconnect the actuator from the supply voltage.
1. Remove housing cover of the electric actuator (loosen the 4 screws,
open cover).
2. Take the fail-safe return unit board out of the packaging and check for
damages.
CAUTION!
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.
CAUTION!
Ensure that the board sits in the lateral guides and snaps.
