4.4 Balancing the Beam

WARNING: This procedure is mandatory as the barrier is not
balanced at the factory. The beam is balanced when, with the
operator released, (ref. par. 5) the beam remains stationary
in the 45° position.
To balance the beam, proceed as follows:
• Install the beam and all related accessories on the barrier
structure, as required by the final configuration of the system.
• Make sure that the operator is released.
• Manually move the beam to the 45° position and verify that it
remains stationary. If the beam tends to open, turn the spring
preload ring nut anti-clockwise (Fig. 16 ref. a); if it tends to
close, turn the ring nut clockwise (Fig. 16 ref. b).
• Adjustements are easily made with the beam in the open
position

5. MANUAL OPERATION

Should manual operation of the barrier be required due to power
outage or malfunction, the manual release device can be operated
with the supplied key. The key is either triangular (Fig. 17 ref. a)
or customised (Fig. 17 ref. b optional).
• Insert the key in the lock and turn it counter clockwise until
it clicks into place, as shown in Fig. 17
• Open or close the beam manually.
With the beam released, the motor may start for
approximately 3 seconds. This is normal and
determined by the parameter Hold Close / Hold Open
5.1 RESTORING NORMAL OPERATION
To avoid an accidental opening the barrier during this operation
turn the power off before using the locking system.
To restore normal operation turn the key clockwise until it stops
and then remove it

6. POWER CONNECTION

The B680H uses a single phase AC power line to operate, char-
ge the optional batteries, and power gate accessories. Use the
following guidelines when installing the AC power:
1. Check the local wiring codes in all cases and follow all local
building codes. Wiring and hookup should be performed by a
qualified electrician/installer only.
2. AC power should be supplied from a circuit breaker panel and
must have its own dedicated circuit breaker. This supply must
include a green ground conductor.
3. Use copper conductor wires with liquid tight flexible conduit UL
listed for electric cable protection
4. Properly ground the operator to minimize or prevent damage
from power surges and/or lightning. Use a grounding rod if
necessary. A surge suppressor is recommended for additional
b
protection.

To connect AC power to the controller:
1. Turn OFF the circuit breaker for the AC gate operator power
before connecting the AC input wires.
2. Turn OFF the Power Switch in the B680H before connecting
the AC input wires.
3. Connect the AC input wires to the power switch in the B680H
See the Fig. 18 for the connections.
4. Connect Ground to the dedicated terminal as shon in the Fig. 18
