Installation Of The Control Box; Techncal Data - Chamberlain MotorLift HC280ML Mechanical Installation

PLEASE START BY READING THESE IMPORTANT SAFETY RULES • SAVE THESE INSTRUCTIONS
This safety alert symbol means "Caution" - failure to comply with such an instruction involves risk of personal injury or damage
to property. Please read these warnings carefully.
This gate drive mechanism is designed and tested to offer appropriately safe service provided it is installed and operated in
strict accordance with the following safety rules.
Incorrect installation and/or failure to comply with the following instructions may result in serious personal injury or property
damage.
When using tools and small parts to install or carry
out repair work on a gate exercise caution and do not
wear rings, watches or loose clothing.
Installation and wiring must be in compliance with
your local building and electrical installation codes.
Power cables must only be connected to a properly
earthed supply.
Any entrapment possibility by the moving wing between
wing & walls must be secured with safety edges or IR-
sensors. .
Please remove any locks fitted to the gate in order to
prevent damage to the gate.
After the installation a final test of the full function of
the system and the full function of the safety devices
must be done.
This drive cannot be used with a gate incorporating a
wicket door unless the drive cannot be operated with
the wicket door open.

INSTALLATION OF THE CONTROL BOX

The control board was designed for installation in a special, waterproof
box (041FA277BX). Before fitting, measure the required distances and
determine the correct holes. Use a screwdriver to force the plastic out
of the holes. Insert threaded cable connections with strain relief, hold
the box against the surface on which it is to be mounted. Insert screws
through the mounting holes in the rear panel and tighten. The motor
control unit is a highly modern electronic unit controlled by a
microprocessor. It has all wiring facilities and functions required for safe
operation. Moisture and water will destroy the control board. Make sure
under all circumstances that water, moisture or storage moisture cannot
penetrate the control board. Make sure that all openings and cable
entries are sealed watertight. The control box with the motor control unit
is mounted with the cable entries facing down. It must not be permanently
exposed to direct sunlight. The electronics can be used for the precise
adjustment of the push-pull torque. The gate can be held by hand if the
fitting/setting is correct. During operation, the gate can be stopped at all
times via remote control, push-button or key-operated switch. The gate
wing requires a firm stop for the "OPEN" and "CLOSED" positions,
because the gate drives have no limit switch.
CURRENT DISTRIBUTION
The cable coming from the drive arm must be inserted into a
commercial, waterproof distribution box. A firm cable connection can
then be established from the distribution box to the control board. It is
frequently possible to lead the drive, that is fixed directly next to the
control board, directly into the box. Never lay distribution boxes under
the ground.
The following minimum cable cross-sections should be used:
• 100-230 volts 1.5 mm² or more more
• 0-24 volts 0.5 mm² or more more
Tips: Bell wires often cause problems when used, because they lose
too much voltage if lines are long. Disconnect the cables in the cable
trunkings i.e. the motor cable and the cable for the photocell, in
particular for key-operated switches and start buttons (coming from the
house), otherwise malfunctions are possible if lines are long.
ATTENTION
IMPORTANT FITTING AND OPERATING INSTRUCTIONS
It is important to make sure that the gate always runs
smoothly. Gates which stick or jam must be repaired
immediately. Employ a qualified technician to repair the
gate, never attempt to repair it yourself.
Keep additional accessories away from children. Do not
allow children to play with pushbuttons or remote controls.
A gate can cause serious injuries as it closes.
Disconnect electric power to the system before making
repairs or removing covers.
A disconnecting device must be provided in the
permanently-wired installation to guarantee all-pole
disconnection by means of a switch (at least 3mm
contact gap) or by a separate fuse.
Make sure that people who install, maintain or
operate the gate drive follow these instructions. Keep
these instructions in a safe place so that you can refer to
them quickly when you need to.
The full protection against potential squeeze or
entrappment must work direct when the drive arms
are installed.
