SLIDING GATES
CONTROL BOARD
5.
The control board will be supplied on request according the
agreement between the manufacturer and his customer. For
the control board installation, please refer to the instructions
enclosed in the control board.
If the control board 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.
Always provide, upstream of the line, a differential overload
mains switch which guarantees a multipole cut-off with
minimum contact opening of 3 mm allowing the complete
disconnection of the control unit and connected equipments
in order to enable the periodic maintenance.
THREE PHASE MOTOR WIRING (Fig.10)
NOTE: to connect a three phase motor, wire the feeding
cables to the U1, V1 and W1 lower terminals, then realise
the jumpers between the upper terminals W2 with U2, and
U2 with V2.
STARTING
6.
For start up the motorized gate it is necessary:
Release the gear motor to allow to move the gate by hand
•
(see “EMERGENCY OPERATIONS” and
fi g.12
);
Move by hand the gate, until the mid way.;
•
Re-lock the gear motor; now thegate can be operated by
•
the motor (see “EMERGENCY OPERATIONS” and
fi g.12
).
Insert the main switch and make sure that the required
•
voltage is available on the terminal board;
Switch the control board to hold to run 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 stop 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 control board.
In the same way check the limit switch operation in
•
closing.
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.
