HANDBOOK / J4C SERIES
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.
ADJUSTMENT OF THE CAMS
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 rst be disconnected. Adjustments, which
need to be done in the energized state, should be carried out with special insulated tools.
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).
Warning! Risk of electric shock inside the actuator. Authorized personnel only.
