INSTALLATION STEP 7
Mounting the Evercharge Standby Power Unit
(SPU) (OPTIONAL)
If the optional CM475 Standby power supply unit is part of this installation
it should be installed at this time (1).
• The SPU can be mounted to either the ceiling or a wall within 80cm of
the motor unit (2).
• Position the SPU as desired to a structural support (ceiling joist or wall
stud).
• Attach the SPU to the support using the mounting holes on either side
of the SPU.
• Secure the SPU using the lag screws (2) provided with the SPU unit.
• Connect the SPU cord into the connector on the bottom of the motor
unit (3).
• Follow all instructions included with the CM475 unit to test for proper
operation and testing of the SPU
INSTALLATION STEP 8
Install the Protector System™ (optional)
The force, as measured on the closing edge of the door, should not
exceed 400 N (40kg). If the closing force is more than 400 N, the
Protector System must be installed.
After opener has been installed and adjusted, The Protector System™
accessory can be installed. Instructions are included with this accessory.
The Protector System™ provides an additional measure of safety
against a small child being caught under a garage door.
It uses an invisible beam which, when broken by an obstruction, causes
a closing door to open and prevents an open door from closing and is
strongly RECOMMENDED for homeowners with young children.

ADJUSTMENT STEP 1
Program the Travel Limits
Travel limits regulate the points at which the door will stop when
moving up or down. Follow the steps below to set the limits.
NOTE: Cable Tension Monitor must be installed
To program the travel limits:
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).
1. Setting the UP position: Press and hold the black button until the
yellow indicator light starts flashing slowly then release.
2. Push and hold the black button until the door reaches the desired UP
(open) position.
NOTE: 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.
NOTE: Excessive movement of the motor unit will cause premature
wear. See Troubleshooting section.
4. Immediately when the door begins to move down, press and release
either the black or orange button. This will stop the door.
5. Setting the DOWN position: Push and hold the orange button until
the door reaches the desired DOWN (closed) position.
6. Once the door is closed, check for proper pressure on the door (you
should be able to manually push the door down a 1/16 of an inch). If
there appears to be too much pressure on the door, you may toggle
the door back and forth using the black and orange buttons to reach
the desired position.
7. Push the remote control or the door control. This sets the DOWN
(close) limit and should bring the door to the open position.
• If the operator is not stopping exactly where you would like it, repeat
steps 1 through 7 and program the limits again.
• When the unit stops in both the desired up (open) and down (close)
positions, proceed to Adjustment Step 2, Setting the Force.
• NEVER learn forces or limits when door is binding or sticking.
Repair door first.
• Incorrect adjustment of the door travel limits will interfere with
proper operation of safety reversal system.
• After ANY adjustments are made, the safety reversal system MUST
be tested. Door MUST reverse on contact with 50mm high object on
floor.
To prevent damage to vehicles, be sure fully open door provides
adequate clearance.
