Electrical actuators type EA 11/ 21/ 31/ 42
Requirements
- Cross section of the power lines max. 1.5 mm2.
- Fuse size: > 6 A.
Ensure that actuator is only connected to voltages that meet the requirements on
a protective extra low voltage circuit (PELV).
Connect actuator, see Section 7.2 Connection diagram
To prevent water getting into actuator, ensure that cable plug is not pointing
upwards.
If temperatures under -10°C plus water condensation are to be expected:
fit "heating element" accessory.
7.4 Adjusting limit switches
The two end positions in the actuator have been factory set to 90°. A
readjustment may be required after assembly by the customer.
Disconnect actuator from voltage.
Open cover. To do so, loosen the 4 screws.
Position both switching cams S1 and S2 (Fig. see Section 6.5) in such a way to each
other that the angle of rotation is less than 90°.
Connect actuator to voltage and let it rotate until a limit switch is activated.
Adjust limit switch until the desired end position is set.
Repeat procedure as required until desired end positions are set.
Fit cover and fasten with the 4 screws.
