Chamberlain HC300ML Installation Électrique page 24

Typical configuration of a unit:
1. Motor
2. Control board
3. photocell (active for closing), max. height 200 mm
First photocell.
4. photocell (active for opening), max. height 200 mm
Second photocell.
5. Flashing light (optional)
Important visual information on the movement of the gate.
6. Key-operated switch
Is mounted on the outside. The gate is opened by key or by
entering a number.
7. Contact strip (optional)
Safeguards the gate on being touched. Contact strips can be
mounted on the gate or on the pillars. If required, contact strips
must be mounted at a height of up to 2.5m.
8. photocell (active for opening/closing), max. height 200 mm
(optional)
The control board complies with the latest EU
guidelines. One of these guidelines specifies that the closing
forces at the gate edge must not exceed 400 N (40 kg) for the last
500 mm before the door is CLOSED. Above 500 mm, the
maximum force at the gate edge must not exceed 1400 N (140
kg). If this cannot be ensured, a contact strip must be mounted on
the gate at a height up to 2.5 m or on the pillar on the opposite
side (EN12453).
MOTORS:
The motor to open first is the "master " motor 1, the other one is
the "second" motor 2. If only one motor is used, the connection
for motor 2 is held in reserve.
The cable for the capacitors supplied with the motors must be
inserted in terminals OP and CL together with the cables for the
direction of rotation (brown/black). For space reasons the
capacitors may also be installed in the distribution boxes. Make
sure that they are connected correctly and powered sufficiently.
The capacitors are responsible for the force that the motors will
have later on.
First connect the motors as follows:
Motor 1
4 Brown & capacitor 1
5 Blue
6 Black & capacitor 1
—————————————————————
Motor 2
7 Black & capacitor 2
8 Blue
9 Brown & capacitor 2
To start up see the section Initial operation / basic setting.
Note: During initial operation, the gate wings must OPEN for
the first run. If one or both wings close(s) instead of opening,
the brown and black cables must be swapped on this motor.
Disconnect from the power supply before doing so!
