INDEX
When “MAN” function is selected:
1 - The electronic system cuts the power to the motor after a few minutes.
2 - The mechanical connection between the motor and the output shaft is disconnected.
3 - The desired position can be achieved by using the hand wheel.
4 - There are two ways to re-active the motor after being isolated whilst in “MAN” position:
a) With the actuator in “MAN” function, turn the hand wheel to one of the end positions (open
or close). If the end position switch is activated the motor stops. Now change the manual
override from “MAN” to “AUTO” , and the actuator is ready to operate automatically again.
b) Change from “MAN” mode to “AUTO”. Deactivate the supply voltage for a few seconds
which resets the actuator and it could operate automatically again.
Under normal conditions, the actuator may only be operated with the closed cover. If work is
performed on the actuator with the removed cover, the supply and control voltage must first be
disconnected. Adjustments, which need to be done in the energized state, should be carried out
with special insulated tools.
How to do it: Tolling: One special plastic wrench (is supplied together with the actuator). The wrench
is tied together with the motor by using one plastic clamp.
To move the cams, introduce the special plastic wrench in the hole of the cam and turn it round
(see both options on the enclosed pictures).
ADJUSTMENT OF THE CAMS
¡WARNING! RISK OF ELECTRIC
SHOCK INSIDE THE ACTUATOR.
