8.2. MANUAL OPENING IN THE EVENT OF POWER FAILURE

8.2.1. PROCEDURE FOR SOLUTION 1 OR 2

The BL229 barriers are available in 4 solutions depending on the position of the boom and the door in relation to the road (

Chap. 6.3, page 18).

The procedure first describes the steps for manual opening in solution 1 or 2:

• Using the key provided, open the access door, disconnect the earthing cable and store the door nearby.

• Switch off the power at the main circuit breaker. Depending on the options selected, the mechanism may unlock itself, in

which case the boom will make a partial or total opening movement.

• If this is not the case in the installed barrier version, a release lever is provided to allow manual opening.

• Rotate the lever clockwise with the left hand (a few degrees are sufficient to leave the alignment position of the crank

system).

• The balancing spring then acts on the main axis of the boom, triggering an opening movement. If necessary, use your right

hand to assist the movement and bring the boom upright.

• Re-engage the circuit breaker to allow the barrier to restart automatically after the 230Vac power supply is restored.

• Replace the earth wire on the gate and lock the barrier shaft.
