Lippert Components Ultra Level - Manual (Page 5)

ERROR MODE
If any problem is detected with the jacks, the system will enter error mode. Error mode may be recognized by the blinking of
LEFT, LEVEL and RIGHT LEDs.
The following errors are detected by this system:
Jack over current/short circuit.
Jack under current/ open circuit.
Jack extending too long (ground not detected after 2 min.).
Jack retracting too long (fully retracted not detected after 2 min.).
Out of stroke detection during auto cycle (if enabled).
The user must respond by pressing ON/OFF switch, which resets operation.
All normal features are disabled in Error mode.
If panel loses communication with the controller for more than 5 seconds, the panel will blink the JACKS DOWN, PARK BRAKE
and ON/OFF (if included) LEDs.
USER ALARM MODE
If the alarm system detects that the park brake has been disengaged while at least one jack is not fully retracted and the sensor
value changes in any axis more than a predefined amount, the panel will signal this error to the user.
When in alarm mode, all LEDs will flash and the buzzer will beep. The Status LEDs will show the system status.
The system performs an automatic retract.
No other features are available in this mode.
MISCELLANEOUS
· The system will automatically shut down after 4 minutes of no operation.
· Auto leveling cycle cannot be started until all jacks are fully retracted. Make sure jacks are retracted before attempting to
auto level (unit will perform full retract automatically if jacks are not down on the request of an auto cycle).
· System will refuse any operation when a low voltage condition is present.
· System will automatically alarm and retract if park brake is disengaged and jacks are not retracted with any change in
sensor readings. In alarm mode, the only available feature is to retract all jacks.
· Please note the Wait LED shows the status of Air/ Auxiliary features.
NOTE - The LEDs blink differently when in special controller modes (error, alarm, and configuration). Learning how to recognize
these modes is important. Excess slope LED blinks whenever the Y axis (vehicle length) is over 5
o from programmed level point.
LOW VOLTAGE SIGNAL
1. If LOW VOLTAGE light is FLASHING, it is indicating that the coach engine is not running. Start coach’s engine to turn
LOW VOLTAGE light off.
2. If LOW VOLTAGE light is on solid, it is an indication of a charging system problem. Turn ignition OFF and then back ON to
reset system. If LOW VOLTAGE light persists, test battery under load at battery and at the motor solenoid on the pump unit.
Check all power and ground connections at the battery, alternator and chassis.
“LATCHED OUT” WARNING
I
CI C
L
FLASHING
LATCHED ERROR mode is “WAIT,” “JACKS DOWN,” “PARK BRAKE,” “EXCESS SLOPE” AND “LOW VOLTAGE” lights flashing.
1. Battery voltage below 10.0V DC.
2. Retract time over 90 seconds in auto retract.
3. This is the only LATCHED ERROR MODE.
4. All revisions prior to “G” controllers treat this error as regular ERROR mode.
To RESET, push all 4 diamond-shaped jack buttons at the same time.
