Chamberlain ARM 1703 Manual Del Usuario página 32

Initial Operation:
The Chamberlain Arm™ has been designed so that, when
used with a Chamberlain manufactured operator, the door will
open to a fully horizontal position (Figure 16).

GPD65!!
Note: The door may be designed in such a way that it does
not open to the full horizontal. Adjust the UP limit so that the
door stops at a slightly downward angle when open.
Note: Safety reversing sensors (Protector System) must be
installed, please refer to your owner´s manual before

When returning to your Owner's Manual, adjust the trolley
travel limits as follows:
1. With the inner and outer trolley sections still disconnected,
manually open your door to the horizontal position. Make a
mark on the rail where the end of trolley nearest to the
operator stops.
2. Manually close the door and mark the rail where the end of
the trolley nearest the door stops.
3. With the inner and outer trolley sections still disconnected,
activate the operator and adjust the limits following the
owners manual of the garage door opener, until the inner
trolley stops on the marks you made. Please read section
"setting limits manually" as found in the HAVING A
PROBLEM section in your owner's manual. While setting
the door limits manually, leave door and operator
disconnected at all times.
4. Reconnect the inner and outer trolley sections so the door
is connected to the operator.

closing correctly.

garage door installing professional.
The Protector System™ (a safety reversing
sensor accessory) must be installed, if the
