EMERGENCY MANUAL OVERRIDE FACILITY
The
J4C
has 2 operating modes, automatic and manual, the required mode is selected by using a lever on the lower
half of the actuator housing (Fig 7).
The 2 positions are marked:
•
AUTO = Automatic operation
•
MAN = Manual operation
EXTERNAL LED LIGHT STATUS
The
LED
status light provides visual communication between the actuator and the user.
The current operational status of the actuator is shown by either solid lit, or different
flashing sequences of the
LED light:
Warning:
Do not remove the selector lever securing screw, as this will allow its internal
mecha
-
nism to become loose and will cause irreparable damage to the actuator’s gearbox.Removing
this screw will invalidate the warranty.
When “AUTO” position is selected:
The hand wheel, of models 20,35,55, and 85 rotates automatically, it is very important not to block it, otherwise the
actuator could suffer unrepairable damages.

When “MAN” function is selected:
1.
The electronic system cuts the power to the motor after a few seconds.
2.
The mechanical connection between the motor and the output shaft is disconnected.
3.
The desired position can be achieved by using the manual override leveror the hand wheel.
4.
There are two ways to reactive the motor after being isolated whilst in “MAN” position:
•
a) With the actuator in “MAN” function, turn the hand wheel to the open or close positions. The motor will
start working. 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.
