FINAL CHECKS AND START-UP

5 FINAL CHECKS AND START-UP

5.1 CHOOSING THE DIRECTION

Choose the direction of the opening manoeuvre on the basis of
the gearmotor's position.
Set the switching device as follows:
– set it to the RH if the spring is attached to the right-hand side
of the balancing lever (factory setting)
– set it to the LH if the spring is attached to the left-hand side of
the balancing lever

5.2 POWER SUPPLY CONNECTION

a
The power supply connections must only be made
by qualified and experienced personnel possessing
the necessary requirements and in full conformity
to the laws, regulations and standards in force.
Connect the control unit to a power line equipped with a safety
earthing system. Install a circuit breaker with a contact gap that
ensures full disconnection in the Category III overvoltage condi-
tions, or mount a plug and socket system.
As soon as the product is powered, a few simple checks should
be carried out:
check that the display switches on.
1.
make sure that the LEDs on the photocells (both the TX
2.
and RX) also flash; the type of flashing is irrelevant, since
it depends on other factors.
check that the device connected to the FLASH output or
3.
the LED warning light XBA7 is switched off (with factory
setting).
If the above conditions are not satisfied, immediately switch
off the power supply to the control unit and carefully check the
electrical connections.
Further useful information on searching and diagnosing faults is
included in the "Troubleshooting" paragraph.

5.3 DEVICE LEARNING

After connecting the power supply, the control unit must learn
the devices connected to the "BlueBUS" and "STOP" inputs.
m
The learning phase must be carried out even if no
device is connected to the control unit.
