Features - Chamberlain LiftMaster Professional LM1000A Service Training Manual

1. LiftMaster openers work with a smooth-operating soft start /soft stop mechanism. The opener
starts more slowly and accelerates immediately thereafter. Shortly before reaching the stop
point, the speed is smoothly reduced again.
2 LiftMaster DC Door Openers 800 and 1000 have an automatic closing system. When a person
enters or leaves the garage, the garage door closes automatically after the programmed period
(4 - 180 sec.) has elapsed. This feature is only available in conjunction with a connected light
barrier. If the beam from the Infrared Sensor is interrupted by an obstacle, it forces a closing
door to re-open and prevents an open door from closing on it.
3. The Protector System (Infrared Sensor) operates with an infrared beam. If this beam is
interrupted when the door is closing, it reverses the door and then opens it fully.
4. All LiftMaster DC openers are equipped with a lighting system intended to accommodate a
light bulb (40W/230V, E27), which is controlled via the opener. The light switches on when the
opener is activated and automatically switches off 2.5 minutes later (factory setting). The
lighting can however be set individually to switch off after 1.5, 2.5, 3.5 or 4.5 min.
5. In the case of models supplied with a multi-function door control panel, the light can be
operated independently of the actual functionality of the door opener.
6. The garage door can be opened using the multi-function door control panel, the illuminated
door control button, the remote control, the keyless entry system or the (outside) keylock.
7. Models supplied with a multi-function door control panel are fitted with a "lock" switch. The
display light behind the switch flashes when the "lock" switch is activated. In this state, the
receiver does not accept any signals from the remote control. The keylock or keyless access
system can however be used to operate the door.
8. The "Smart" receiver has 16/32/64 memory registers (600A/800A/1000A). Each memory
register can be used for a remote control or keyless entry system. The receiver and remote
controls work on the basis of the rolling code principle, i.e. the code that is transmitted
whenever a button is pressed is changed each time. A code that has already been transmitted
cannot be re-used. Up to 12 billion codes can be transmitted. Moreover, each remote control is
equipped with its own individual code.
9. The garage door opener can be stopped at any time to, for instance, give the garage an airing.
The PosiLock™ System is only active when the door is in a closed state. The PosiLock™
System "secures" the door 27 seconds after it has reached its end point of travel. If rotation is
recognized by the motor when opening, the microchip orders the opener to then close again.
The safety reverse facility is not active in such cases.
10. All models are compatible with the Infrared Sensor (770E). The sensors are fitted on both sides
of the garage door and operate with an invisible infrared beam. The door is forced to
immediately reverse before it makes contact with any given obstacle.
11. Electronic limit switches - the positions "UP" (OPEN) and "DOWN" (CLOSE) are
electronically regulated in a precise manner. Please follow all the steps described in the
instructions in full.
12. Door-in-door (slip-door) contact – the slip-door contact serves to secure an "access door"
(communication door) built into a garage door. If switch 16200LM is not installed, the jumper
must then be left connected on the opener.
13. Flashing light. Connect both wires to the FLA230 flash-lamp on the terminal unit. When the
opener is operated, the flash-lamp starts flashing two seconds prior to the door starting to move.
A 230 volt power supply is additionally needed for the light bulb in the flash-lamp.
14. Coaxial aerial connection (ANT4X-1LM) – an outside aerial is available as an accessory in
cases where the range of the remote control is inadequate or structural specifics reduce its
range. An aerial can be created using a standard 75 ohm coaxial cable (television aerial cable).
The original aerial must be cut off for this purpose. Use a coaxial cable with a plug connection.
250mm of insulation should stripped from the outside end of the cable. Fix the aerial as high up
as possible to achieve optimum range.
