How To Proceed - Chamberlain HC250 Instructions

2.1 FRONT SUPPORT ASSEMBLY
After the plate fixation, install the actuator the pivot (Fig.1).
Then provide for the "STOP" installations on the ground.
• Open the gate wing till the desired position is reached
• Now the front plate can be fixed following this scheme.
Proceed as follows:
1. Open the wing till the STOP is reached.
2. Lay the actuator on the gate with the rod COMPLETELY INSIDE
(position perfectly horizontal).
3. Fit the plate, as shown in the illustration, and test while closed.
4. Then fix the plate to the gate by means of screws or by welding it
to the gate.
It is advisable to check the good operation of the movement by
opening the gate wings manually. Do not exceed the maximum length
of 900mm.
2.2 SECOND ACTUATOR ASSEMBLY
Repeat the operation for the other gate wing, following the same steps
2.0 and 2.1.
Note: Fixation measures of the second actuator shall be the
same as the first ones.

3.2 SPECIAL CONNECTIONS

HOW TO PROCEED:

1. First of all make the low voltage connections: Motors, Flashing
lamp, Keyswitch and possibly optional connections as photocells,
antenna.
2. Then connect the supply line to the 230V 50Hz transformer
(Fig. 12).
3. LED LD1 (green) will light up.
4. At the first START pulse the gate will move.
Caution: This operation shall be carried out with closed
wings, consequently the first operation will be the gate
opening.
Fig. 4 - 7 3.3 SETTINGS
Automatic close ON:
• Press and hold button P3, until the LED (red) will light up.
• Release button
• Wait for the desired time (open time - door open)
(approx. 120 seconds.)
• Again, press button P3
During the opening cycle it is not possible to interrupt the movement
with a push button or transmitter. The actuator will stop during the
closing cycle and opens again.
Automatic close OFF:
• Press button P3 at least 10 seconds. First, the red LED will lighten
up and will turn off after approx. 10 seconds.
Force adjustment: The electronic control automatically adjusts to the
necessary force. If adjustage (in case of windy conditions) should be
necessary, move the wings to the schwergängiste position of the gate.
• Press button P2 until the green LED lightens up.
• The electronic control will test the the necessary force for
approx. 20 seconds. The green LED will turn off.
According to the regulations for automated shutters, doors and
gates - the force on the main closing edge may not exceed 150N
(15kg).

problems.

The protection system by means of photocells is composed of one or
more PAIRS of devices, one of them is the TRANSMITTER and the
other is the RECEIVER (Fig.16-17).
The first transmits an invisible infrared ray picked up by the receiver; in
case the ray were interrupted the equipment will open a relay which
shall transmit a signal to the programmer that shall provide to invert

duct crossing the gate width.
1. Cable having a minimum cross section of 0.5mm
2. In case of double safety device, provide for a DOUBLE PASSAGE.
3. Position the receiver in front of the transmitter at the same height
4. The red led off indicates a perfect alignment.
5. Install the photocells cables far from cable ducts to avoid
