Override Modes (continued)
In the event of component failure or loss of system power, your bunk can be manually
overridden and bunk moved for travel.
Note:
At any time during the override procedure, the unit will exit this mode if the bunk has
not been moved for two (2) minutes or if a fault is detected during bunk movement. The
FAULT CODE and BUNK MOVEMENT LED’s will flash rapidly for 10 seconds to indicate
that the override procedure failed. After the 10 seconds of flashing, the control will
automatically default to FAULT CODE 1 (see FAULT CODES, FIGURE 5) and programming
must be restarted.
Note: The bunk control will need to be re-programmed by an authorized dealer after
the system has been overridden
.
A. EMERGENCY BUNK MOVEMENT TO UP POSITION:
Use this procedure when there is NO loss of power or electrical problem with the
system.
1. Remove the touchpad (
FIGURE 1, page 1
) from the wall.
2. Prior to clearing the MAJOR fault, record the number of RED and GREEN flashes
(
FIGURE 6
) observed on the touchpad. This information will help your
dealer/service center in troubleshooting the bunk lift system.
3. Press and hold the
SET STOPS/CLEAR FAULTS
button (
FIGURE 3, page 2
) on
the back for the touchpad for five (5) seconds. Both
RED

on solid while this button is pressed. After five (5) seconds, the
GREEN
LED will
begin flashing and the
RED
LED will remain lit.
4. The unit is now ready to raise the bunk. Press and hold the
BUNK LIFT MOTOR
buttons 1 and 2 on the back of the
TOUCHPAD
(

bunk lift control has NO stop locations. Damage to the bunk lift can
occur if the bunk is raised or lowered too far.
5. Press the UP button on the front of the wall touchpad until the bunk is fully raised
position. If one side of the of the bunk needs to be raised further in order to fully
raise, press and hold the motor button corresponding to only the motor you want to
move. Press the UP button on the front of the touchpad to raise the bunk the
remainder of the way. Install lock pins. ( if equipped)

B. MANUAL EMERGENCY BUNK MOVEMENT TO UP POSITION.
Use this procedure when the above procedures do not work.
In the event that power is lost to the bunk motor(s) or
OVERRIDE MODE “A”
(
page 4
) will
not work, the bunk can be manually raised by following these steps:
1. Use a voltmeter and check to see if power is being delivered to the control module.
2. If no DC power is being delivered from coach, use another 12 VDC battery power source
to power the module and retract the bunk using the
UP
button on the touchpad.
3. If power source is not available, then use the following steps:
a. Gain access to channel assemblies on each side of the bunk by first
contacting the OEM manufacturer for access details.
b. Once access is gained, remove the top cover plate of each channel assembly.
c.
Loosen motor retainer screw or unhook spring, do not remove screw.
(FIGURE 7)
d. Remove each motor from the channel assembly. Bunk will drop if in the raised
position.
e. Disconnect motor connectors and place motors in a safe location. They will be
needed when bunk lift is serviced.
f.
Manually push up bunk lift.
4. When bunk in fully raised position, install pins to keep it in place.
