Operation Of Your Opener; Specifications - Merlin MT600 Installation And Operating Instructions Manual

15. Setting the limits manually:
1. Press and hold the black button until the yellow indicator light starts flashing slowly then release.
2. Adjust the position of the door by using the black and orange buttons. Black moves the door UP (open) and orange
moves the door DOWN (close).
Check to be sure the door opens high enough for your vehicle.
3. Push the remote control or door control. This sets the UP (open) limit and begins closing the door.
Immediately press either the orange or the black button. The door will stop.
Adjust the desired DOWN (close) limit position using the black and orange buttons. Check to be sure the door is fully
closed without applying excessive pressure on the rail (rail should not bow upwards and the chain/belt should not sag or droop
below the rail). Push the remote control or door control. This sets the DOWN (close) limit and begins opening the door.
NOTE: If neither the black or the orange button is pressed, the door will reverse off the floor and the DOWN travel limit will be
set automatically.
4. Open and close the door with the remote control or door control 2 or 3 times.
• If the door does not stop in the desired UP (open) position or reverses before the door stops at the DOWN (close) position,
repeat Setting the Limits and Force, see adjustment steps 26 and 27.
• If the door stops in both the desired UP (open) and DOWN (close) positions, proceed to Test the Safety Reversal System.

OPERATION OF YOUR OPENER

Your opener can be activated by any of the following devices:
• The Lighted Door Control Button. Hold the button down
until door starts to move.
• The Outside Keylock or Keyless Entry System (if you
have installed either of these accessories).
• The Remote Control Transmitter. Hold the push button
down until the door starts to move.
Opening the Door Manually: Door should be fully closed
if possible. Weak or broken springs could allow an open
door to fall rapidly. Property damage or serious personal
injury could result.
The door can be opened manually by pulling the release
handle down. To reconnect the door, pull the release handle
down and toward the opener.
Do not use the manual release handle to pull the door
opener or closed. When the Opener is Activated by
Remote Control or Lighted Door Control Button:
1. If open, the door will close. If closed, the door will open.
2. If closing, the door will stop.
3. If opening, the door will stop (allowing space for entry and
exit of pets and for fresh air).
4. If the door has been stopped in a partially open or closed
position, it will reverse direction.
5. If an obstruction is encountered while closing, the door will
reverse.
6. If an obstruction is encountered while opening, the door will
reverse and stop.
7. The optional Protector System™ uses an invisible beam
which, when broken by an obstruction, causes a closing
door to open and prevents an open door from closing. It is
STRONGLY RECOMMENDED for homeowners with young
children.
