Electrical connections

WARNING!
- An incorrect connection can cause faults or dangerous
situations; therefore, scrupulously comply with the indicated
connections.
- Perform the connection operations with the power supply
disconnected.
To connect the gear motor proceed as follows:
1. Remove the gear motor cover
2. Loosen the cable gland of the gear motor and insert the
connection cables
FIG.12
16
3. Bring the cables to the top of the motor near the control unit
4. For how to connect the two motors, refer to the manual of the
"Control unit" supplied with the rest of the documentation;
5. After making all the electrical connections, replace the cover
on the gear motor.
To check the connections, the direction of rotation of the motor, the
displacement of the movement of the leaves and the adjustment
of the limit switch, refer to the instruction manual of the "Control
unit".
5. Testing the automation
In order to guarantee maximum safety, this is the most important
phase in the realization of the automation. The test can also
be used as a periodic check of the devices that make up the
automatism.
The testing of the entire system must be performed
by expert and qualified personnel who must take
responsibility for the required tests, according to the present
risk and verify compliance with the provisions of laws, regulations
and standards, and in particular with all the requirements of the
EN12445 standard which sets out the test methods to verify gate
automatisms.
Testing
Every individual component of the automatism, for example safety
edges, photocells, emergency stop, etc. requires a specific
testing phase; for these devices, the procedures indicated in the
respective instruction manuals must be carried out.
To test the gear motor, carry out the following operations:
1. Check that all the provisions of this manual and in particular
chapter 1 have been strictly adhered to;
2. Release the gear motor as shown in Fig. 8;
3. Verify that it is possible to manually move the opening and
closing leaf with a force not exceeding 390 N (about 40kg);
4. Lock the gear motor and connect the power supply;
5. Using the control or stop devices provided (key selector,
control buttons or radio transmitters), carry out tests to
open, close and stop the gate and verify that its behaviour
corresponds to what was expected;
6. Check one by one that all the safety devices present in the
system (photocells, safety edges, emergency stop, etc.) work
correctly; and that the gate's behaviour corresponds to what is
expected;
7. Order a closing manoeuvre and check the force of the impact
of the leaf against the stop of the mechanical limit switch. If
necessary, try to relieve the pressure by finding an adjustment
that gives better results;
8. If the dangerous situations caused by the movement of the
leaf have been safeguarded by limiting the impact force, this
force must be measured according to the provisions of the EN
12445 standard;
Note – The gear motor has no torque adjustment devices,
therefore, this adjustment is entrusted to the control unit.
