4.4. ADJUSTING THE BALANCE SPRING
IMPORTANT!: The barrier is supplied already balanced for the exact beam length specified in the order (see the
Barrier Order Specifications, in the price list, and TAB. 2 - 3)
Should a fine adjustment of the beam balance be needed, proceed as follows:
1) Unlock the operator, as indicated in paragraph 6 .
2) Adjust the pre-loading ring nut, using the spanner supplied, as shown in Figure 12.
The beam is correctly balanced when it remains steady in the 0° e 90° positions.
If the beam tends to close, turn the ring nut clockwise.
If it tends to open, turn the ring nut counterclockwise.

5.1. CONNECTING THE ELECTRONIC UNIT
Important! Disconnect the power supply before you perform any type of operation (connections, programming or maintenance) on the electronic unit.
Warning: When terminal strip J2 is disconnected, the power supply outputs of the motor, fan and flashing lamp are still connected to electric power.
Follow points 10, 11, 12, 13 and 14 of the GENERAL SAFETY
REGULATIONS.
Position the pipes, as shown in Figure 3, and connect the
624 MPS electronic unit to the accessories.
Keep the power supply cables separate from the control and safety signal ones (photocells, receiver, pushbutton, etc.). To prevent electric interference, use separate pipes.

This word indicates a activating device with normally closed contact, whose activation suspends the current status of the beam (opening, pause or closing), until another pulse is sent.
SAFETY
This word indicates all devices (photocells, sensitive pneumatic safety edges, magnetic coils) with normally closed contact, which interrupt the movement of the beam whenever there is an obstacle within their range.
PANIC
This word indicates a activating device with normally closed contact, which is activated in an emergency and causes the beam to open, suspending its current status
(open) until the RESET pushbutton is pressed.

OPERATION OF SAFETY DEVICES
In the A or E logics, it is possible to obtain two different types of safety device operation, depending on the pause times that are selected:
- PAUSE TIMES WITH LAMP PRE-FLASHING (10-20-30-40 sec): the closing movement is stopped, then reversed on disengagement.
- PAUSE TIMES WITHOUT LAMP PRE-FLASHING:(0-5-10-20 sec): the closing movement is reversed at once.

OPEN
This word indicates any activating device with normally open contact, whose activation causes the beam to perform an opening movement. In automatic and semi-automatic logics, it controls both opening and closing movements.
CLOSE
This word indicates any activating device with normally open contact, whose activation causes the beam to perform a closing movement. (Present only in P logic).

ALARM CONDITION
It arises in the following cases:
1) Enabling of anti-panic input.
2) Activation of safety TIME-OUT device, which interrupts the operation of the system when operating time exceeds 30 sec.
3) Simultaneous triggering of the two limit switches.
4) Microprocessor reading anomaly (syncro).
The alarm condition is indicated by the quick flashing
(0.25 sec) of the Warning Light LED and of the warning light (if connected).
In this condition, all the functions of the system are disabled. Normal operation is restored only after the cause of the alarm has been eliminated and the RESET pushbutton has been pressed.

(**) Warning light connected between terminals 9 and 10.
5.2. ADJUSTMENT OF TRANSMITTED TORQUE
Use the two by-pass screws (fig. 8) to regulate the hydraulic transmitted torque adjustment system.
The red screw adjusts torque during closure.
The green screw adjusts torque during opening.
Turn the screws clockwise to increase torque.
Turn the screws anticlockwise to reduce torque.
5.3. ADJUSTMENT OF STROKE END DECELERATION
1) Position microswitch SW6 according to the amount of deceleration required:
OFF: SHORT (1.5 sec).
ON: LONG (2.5 sec).
For beams up to 4 m long, a short deceleration is recommended. For beams from 4 to 7 m, a long deceleration is recommended.
2) Adjust the stroke limit cams by loosening the two Allen screws, as shown in Figure 17. To increase the deceleration angle, move the cam toward the limit switch. To decrease the deceleration angle, move the cam away from the limit switch.
3) Re-lock the system (see paragraph 6), and carry out a few test cycles, in order to check whether the positioning of the limit switches, the balancing of the spring, and the transmitted torque are correct.

5.4 TESTING THE AUTOMATION SYSTEM
Once installation is complete, affix the danger warning adhesive on the top of the housing (Fig. 18).
Carry out a thorough functional check of the barrier unit and all accessories connected to it. Give the page entitled
“End-user guide” to the customer and demonstrate how to operate the barrier correctly, drawing the customer’s attention to the points of potential danger.

If the barrier needs to be operated manually as a result of a power failure or malfunction, use the unlock device as follows.
The key provided can be triangular (standard) or personalised (optional).
