α-MAX Electric Actuators types ER 20-45-60-100
Installation and operating instructions
Electric motor
DD shaft
Manual operation
Distribution PCB
In case of power failure, it is possible to operate
the valve manually. Remove the visual indicator
on top side. For manual overriding, turn
the clutch knob from AUTO to MAN and the
outgoing shaft on top (double-D) can be moved
clockwise for closing the valve. The double-D
Cam nr. 4 – closed indication (black)
clearly shows the valve position.
Terminals
Cam nr. 3 – open indication (white)
Cam nr. 2 – closed position (black)
Cam nr. 1 – open position (white)
Base housing
Adjustment key
CAUTION
• When the actuator is field mounted, the label on
the base housing shall be parallel to the piping.
• Do not connect several actuators on the same
current reverser without live separation.
• This actuator is factory tested. The limit
switches have been set for 90° use.
• Disconnect power supply before:
- removing the cover
- disconnecting the gear
- using manual override facility
• Consult technical data sheet before mounting
the actuator onto the valve.
• This actuator is weatherproof to IP65 and
maintenance is negligible.
Notes
• All cams are self-locking and do not require further
tightening.
• Switch point can be adjusted by turning the cam(s)
with the use of the adjustment key.
Closed position
- counter clockwise for later contact response
- clockwise for earlier contact response.
Open position
- counter clockwise for earlier contact response
- clockwise for later contact response.

Electric Wiring
1. Power and remote connection
- Untighten the four screws with a screwdriver,
and remove the cover from the base housing.
- Unscrew the Pg11 cable gland, insert the
cable into the plug cover and proceed as
follows:
Alternating current / AC
Connect the earth of faston
Connect neutral in 1
Connect the wire of ‘open’ to terminal 2
Connect the wire of ‘close’ to terminal 3
(phase in 50/60 Hz alternatively on 2 and 3)
Direct current / DC
Connect 1 and 2
Make a shunt between 2 and 3
Earth connection is optional
Reverse the connections, if opening and
closing are not in the right position
- Reinstall the cover, fasten the four cover
screws and tighten the cable gland.
2. Auxiliary limit switch connection
As standard, those actuators are provided
with two auxiliary limit switches (adjusted for
90° angle rotation).
Electric wiring as follows:
- Connect terminals 4 and 8, and 6 and 9 to use
the NC function of LSO 2 and LSC 2
- Connect terminals 4 and 5, and 6 and 7 to use
the NO function of LSO 2 and LSC 2
