ELECTRICAL CONNECTIONS
CAUTION!
– Incorrect connections can cause faults or hazards; therefore ensure that the specified connections are strictly observed.
– Hook up the unit with the electrical power shut off.
The gear motor is supplied with an electric power input cable measuring 2 m. Therefore, if a gr eater distance must be covered to perform the
electric connections, a diversion box must be used (not supplied). IMPORTANT! – It is prohibited to join the electric cable inside the
foundation case.
To connect the power input cable to the control unit, see the manual regarding the latter and the following indications:
• For LFAB4000 connect the cables as follows:
WIRE CONNECTION
Black wire “Open” phase
Brown wire “Close” phase
Grey wire Common
Yellow/Green wire Earth
• For XLFAB5024 - LFAB4024 - LFAB4024HS connect the ca-
bles as follows:
WIRE CONNECTION
Blu wire 24 V motor power supply
Brown wire 24 V motor power supply
Black wire Encoder
Grey wire Encoder
Yellow/Green wire Earth

AUTOMATION TESTING
These are the most important stages in the automation’s construction in order to ensure maximum safety. Testing can also be adopted as a
method for periodically checking that all the various devices in the system are functioning correctly.
Caution!
– In order to limit impact forces, a sensitive edge must be used.
Testing of the entire system must be performed by qualified and experienced personnel
who must establish which tests to conduct on
the basis of the risks involved, and verify the compliance of the system with applicable regulations, legislation and standards, in particular with all the
provisions of EN 13241-1 which establishes the test methods for automation systems for gates.
5.1 - Testing
Each component of the system, (safety edges, photocells, emergency stop, etc.) requires a specific testing phase. To do so, follow the proce -
dures given in the instruction manuals.
Run the test as follows:
01. Ensure that the instructions outlined in this manual and in particular in chapter 1 have been observed in full
02. Close the gate
03. A TTENTION! – Remove any electric power input source to the control unit
04. Release the gear motor using the relative wrench
05. Open the panel manually until the maximum opening position is reached and check that there is no friction during the movement
06. Check that the panel, left in any position of its run, does not move
07. Check that the safety systems and the mechanical stops are in good working order
08.
Check that the screw connections are well-fastened
09.
If necessary, clean the inside of the foundation case and check that the water drain functions correctly
10.
Block the gear motor using the relative wrench
11.
Apply the electric power input to the control unit
12. Measure the force of impact according to that envisioned by the EN 12445 Standard. If the control of the “driving force” is used by the
control unit as an auxiliary to the system for the reduction of the force of impact, try and adjust the functions that offer better parame-
ters. LFAB(...) / XLFAB(...) is not equipped with any torque adjustment device, therefore this operation is performed by the control unit
13. Permanently fix a label, which describes how to manually release the gear motor, in a zone adjacent to the automation
5.2 - Commissioning
Commissioning may only be done when all the gearmotor tests specified in par. 5.1, and those of the other equipment, have been passed: to
commission the unit, refer to the control unit manual.
IMPORTANT - It is not permissible to execute partial commissioning or to enable use of the system in makeshift conditions.
