Installation note

If the actuator is directly connected to the power supply, it
is necessary to install a disconnector between the actuator
and the power supply (do not disconnect the earth cable).
Cross-section of the external cables max. 1,5 mm
To avoid water flowing into the actuator, make sure the cable
entry point is not upturned.
The EA 21/31/42 has a temperature control (ready-to-
operate monitoring).
Due to the loading of the power supply capacitor
when first time switching on the actuator current
peaks can occur for a few micro seconds. The-
refore we recommend to connect the actuator in
accordance with accompanying wiring diagram.

5.2 Error message

If an error occurs, the red LED (8) on the base board will
light up.
If the monitoring print is installed, the LED (7) on the BCD
switch (10) which selected value has been exceeded will also
light up red.
With all occurring error messages the ready-to-operate
signal will be off (terminals 5,6 no passage).
Eliminating the error message
Check the error cause, if necessary carry out the appropri-
ate maintenance.
To eliminate the message, activate the reset switch (9) on
the base board while the supply voltage is still connected
or briefly disconnect the actuator from the mains voltage.
