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
Fig. 11
and safety signal ones (photocells, receiver, pushbutton,
etc.). To prevent electric interference, use separate pipes.
