HAVING A PROBLEM? (Continued)
5. Door reverses for no apparent reason and opener lights don't
blink:
• Is something obstructing the door? Pull manual release handle.
Operate door manually. If it is unbalanced or binding, call for
professional garage door service.
• Clear any ice or snow from garage floor area where garage door
closes.
• Review Force Adjustment.
• If door reverses in FULLY CLOSED position, reset the limits.
Repeat safety reverse test after adjustment is complete.
The need for occasional adjustment of the force and limit settings is
normal. Weather conditions in particular can affect door travel.
6. Door reverses for no apparent reason and door control button
light blinks for 5 seconds after reversing:
Check The Protector System™ (if you have installed this accessory).
If the light is blinking, correct alignment.
7. Opener noise is disturbing in living quarters of home:
If operational noise is a problem because of proximity of the opener to
the living quarters, Vibration Isolator Kit 41A3263 can be installed.
This kit was designed to reduce the "sounding board effect" and is
easy to install.
8. The garage door opens and closes by itself:
• (Keypad or code switch transmitters only) Is there a neighbor with a
garage door opener using the same code? Change your code.
• Make sure remote push button is not stuck in ON position.
9. Door reverses or doesn't close completely:
If it reverses or stops within 50mm of the floor, review "Force
Adjustment" and increase force. If necessary, repeat "Program the
Travel Limits."
Repeat safety reverse test after any adjustment of door arm
length, close force or down limit.
10. Door opens but won't close:
• Check The Protector System™ (if you have installed this accessory).
If the light is blinking, correct alignment.
• If opener lights do not blink and it is a new installation, check the
down force.
Repeat the safety reverse test after the adjustment is complete.
11. Opener light does not turn on:
Replace light bulb (40 Watts maximum). Replace burned out bulbs
with rough service light bulbs.
12. Opener light does not turn off:
There may be a defective earth at the ceiling or wall receptacle. The
unit must be earthed.
13. Opener strains or maximum force is needed to activate door:
Door may be unbalanced or springs are broken. Close door and use
manual release rope and handle to disconnect trolley. Open and close
door manually. A properly balanced door will stay in any point of travel
while being supported entirely by its springs. If it does not, call for
professional garage door service to correct the problem. Do not
increase the force to operate the opener.
14. Opener motor hums briefly, then won't work:
• Garage door springs are broken. SEE ABOVE.
• If problem occurs on first operation of opener, door may be locked.
Disable door lock.
15. Opener won't activate due to power failure:
• C-rail: Pull manual release handle straight down to disconnect trolley.
Door can be opened and closed manually. Rotate lever to reconnect
trolley. T-rail: Pull manual release handle down and back (toward
opener) to disconnect trolley. When power is restored, pull handle
straight down.
The next time the opener is activated, the trolley will reconnect.
• The Outside Quick Release accessory 1702E (if fitted) disconnects
the trolley from outside the garage in case of power failure.
16. When in the limit learn mode, the opener will not
automatically stop and reverse when the door reaches the
floor.
The PRO7100 uses a switch, internal to the motor, as a reference or
"pass point" to regulate limit adjustment. This point must occur ONLY
ONCE in the trolley's travel range, preferably about 75-90 cm from the
fully closed position. The opener is factory preset with the pass point
in the correct position for installation. However, if the PRO7100 was
bench tested before installing the rail, the pass point could be outside
the desired position, or could occur twice.
a. Determine the pass point. The wall pushbutton green indicator light
will blink momentarily when the pass point occurs.
b. If the pass point is incorrectly positioned or occurs more than once,
disconnect power immediately at the first blink.
c. Remove the chain from the sprocket and reposition the trolley to 75-
90 cm from the closed position. Be certain the metal release lever is
in the latched position (see Illustration 13, center view, ).
d. Reinstall the chain and reprogram the limits. The push-button
indicator light should now blink ONCE at the correct position.
SPECIAL FEATURES OF THE PRO7100
A. Door within a door connection
Remove jumper (not shown) from terminal leads 1 and 2 on auxiliary
terminal block. Replace with contact switch leads as shown.
B. Flashing light connection
The flashing light can be installed anywhere. Connect light leads to
terminals 3 and 4 on the terminal block. When the opener is
activated, the light will begin to flash two seconds before the door
moves, and continue flashing while the door is in motion. See
flashing light instructions.
C. Coaxial antenna adapter
A coaxial antenna connection can be used if the transmitter range
is too short. Cut off the existing antenna. Use standard coax cable
and connector. Strip off end of insulation to 250mm. Reposition
antenna.
