3.5 - Installation
To install the gearmotor, perform all the steps shown in the figures, starting
from Fig. 1 to Fig. 18. You must strictly follow the order as shown.
3.6 - Manual release and block of the gear motor
To release or block the gearmotor, use the lever provided in the following way:
• To release a gate leaf (reference to Fig. 19):
01. Choose the side of the leaf you want to work on.
02. Gain access to the lock by turning its cover 180° (test it to see which way
you need to turn it).
03. Insert the lever in the lock and turn it 180° in a clockwise direction.
04. Remove the lever from the lock and put the cover back on the lock.
05. Lastly, move the leaf by hand to its desired position.
• To lock a gate leaf (reference to Fig. 20):
01. Choose the side of the leaf you want to work on.
02. Gain access to the lock by turning its cover 180° (test it to see which way
you need to turn it).
03. Insert the lever in the lock and turn it 180° in an anti-clockwise direction.
04. Remove the lever from the lock and put the cover back on the lock.
05. Move the leaf by hand to a position by the lock; finally release it only after
hearing the click of the lock (= door locked onto the gearmotor).

ELECTRIC CONNECTIONS

Recommendations:
- The gearmotor must only be connected to the MC824L control unit.
- The gear motor is supplied with an electric power input cable measuring 3
m. So if you need to cover a greater distance in order to connect it to the
MC824L control unit, it is essential to use a junction box (not supplied)
to adequately protect the added sections of electrical cable.
- Make the electric connections with the mains power input discon-
nected.
To connect the power input cable to the control unit, see the manual regarding
the latter and the following indications:

Blu wire 24 V motor power input
Brown wire 24 V motor power input

INSPECTION AND COMMISSIONING
These are the most important stage in the automation system installation pro-
cedure in order to ensure the maximum safety levels.
Testing can also be adopted as a method of periodically checking that all the
various devices in the system are functioning correctly.
CAUTION! – The system must be tested by skilled and qualified per-
sonnel, who is responsible for defining the tests adopted in relation to
the risks present, and for ensuring observance of all legal provisions,
standards and regulations, with particular reference to all requirements
of the EN 13241-1, EN 12445 and EN 12453 standards which defines the
test methods for testing gate automations.
5.1 - Inspection
Each individual component of the automation, e.g. sensitive edges, photocells,
emergency stop etc requires a specific inspection phase. For these devices
the procedures given in the respective instruction manuals must be performed.
When conducting tests on the gearmotor, proceed as follows:
1 Check that everything envisioned in Chapter 1 - General safety warnings
and precautions, is rigorously respected.
2 Close the gate.
3 Remove any electric power input source to the control unit.
4 Release the gear motor using the relative wrench (see paragraph 3.6).
5 Move the gate leaf by hand to its maximum opening position; during move-
ment make sure there is minimum friction and that constant force is used
throughout the travel: there must be no points where the friction is greater
2 – English
than elsewhere.
6 Move the gate leaf by hand and leave it still at various points along its travel;
then make sure that the gate leaf remains in balance, i.e. it does not move.
7 Make sure that the safety systems and mechanical stops are in good condition.
8 Make sure that the screw terminals used for the electrical connections are tight.
9 Block the gear motor using the relative wrench (see paragraph 3.6).
10 Apply the electric power input to the control unit.
11 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 parameters.
12 Place the label showing how to manually release and relock the gearmotor
in a position close to the automated unit.
5.2 - Commissioning
Commissioning can only be performed after all of the inspection phases of the
gear motor and other devices present have been performed with positive re-
sults. For commissioning refer to the control unit instruction manual.
IMPORTANT – Partial commissioning or in "temporary" situations is
prohibited.

PRODUCT MAINTENANCE

Maintenance must be performed in strict observance of the safety provi-
sions in this manual and according to current legislation and standards.
The automation devices do not require special maintenance. However a check
should be performed at least every six months to ensure complete efficiency
of all devices.
For this purpose, the tests and checks envisaged in paragraph 5.1 "Testing"
should all be performed, as well as all procedure in the paragraph "Maintenance
operations permitted for the user".
If other devices are present, follow the instructions in the relative maintenance
schedule.
If the motor is replaced, it is possible to use the replacement pin and move the
gate manually: to insert the pin see Fig. 21.
