Using the Key
1.
Turn the bypass valve to the
OPEN
position (Fig. 1A). The bypass valve should be located in the same
compartment as the air compressor.
2.
Make sure people and objects are clear of the door when first opening the door after shutting off the
bypass valve as some air may still be in the air hose line.
Troubleshooting
What is
Happening
Why?
What Should Be Done?
Door does not
open or close.
Key is in the ignition.
Remove the key from the ignition.
No power.
Check if the power source is fully charged.
Batteries in key fob or flex
switch need to be replaced.
Replace key fob with a L1028F Battery.
Replace the flex switch with an A23 Battery.
Check to see if the in-line fuse
is blown.
Replace with a 20AMP fuse.
Check to see if the RC35b Relay
fuse is blown.
Remove from the air compressor tray and open
the RC35b relay switch. If the fuse is blown inside
the relay, order a replacement RC35b relay.
Bypass valve not in the correct
position.
The bypass valve must be in the closed position
(Figs 1B, 4B) to operate with the use of the air
compressor.
When operating the Challenger door and the door does not open with the remote, the BYPASS VALVE
(Fig. 4A)
MUST
BE CLEARED OF AIR
FIRST BEFORE OPENING THE DOOR
with the key.
Switch the bypass valve to the OPEN position (Fig. 4A) from the closed position (Fig. 4B).
The Challenger Door Series 1520 is in use with an air compressor, which when in use, can cause
the door to rapidly open. Should an error arise and the door does not open, ALWAYS drain the air out of
the air compressor's bypass valve before attempting to manually open the door. There is NOT an object
sensor on the door. Keep all people and personal property away from the door area when opening and
closing the door. Failure to adhere to this warning will result in severe product and unit damage, including
serious personal injury or death.
