CONTROL UNIT
The control unit is supplied on request according the
agreement between the manufacturer and his customer. For
the control unit installation, please refer to the instructions
enclosed in the control board.
If the control unit is not supplied by the manufacturer of the
gear motor, the installer must check that the control board
utilized comply with:
the in force standard and regulations;
•
the features of the gear motor;
•
the features and the way of working of the safety devices;
•
the type of working cycle, the operating conditions, the
•
controls utilized and the safety devices.
the control unit must ensure the control of reversing,
•
reducing the inertia of the gate.
STARTING
3.
For starting up the motorized gate it is necessary:
Release the gear motor to allow to move the gate by
•
hand;
Move by hand the gate, until the mid way.;
•
Re-lock the gear motor; so that the gate can be operated
•
by the motor.
Insert the main switch and make sure that the required
•
voltage is available on the terminal board;
Switch the control unit to manual control or semi-automatic
•
control (depending on the control unit);
Give an opening input and make sure that the gate is
•
moving in the opening position: if not, cut off the power
and change the wiring of motor cables or on the control
unit terminal board, as needed;
During the opening movement of the gate, before the full
•
stroke is reached, act manually on the limit switch lever to
verify if it stops the opening gate movement. If not, cut off
the power before the full stroke is reached; then change
the wiring of motor cables or of the limit switch cables. In
the same way check the limit switch operation in opening
and closing.
Adjust the clutch inserted between the motor and the
•
gear so that it doesn't slip under the motor pickup from a
standing start.
Note: the clutch was not designed to function as a torque
limiter according the in force regulations.
Check that the gate stops at the end of stroke position
•
as you desire; if not, adjust again the plates: advance or
postpone the limit switch intervention, as you need.
We suggest to check again the limit switch adjustment after
few days of operation.
N.B. It is necessary to install mechanical stops in
opening and closing position to prevent derailment of
the gate in case of limit switch failure.
