SECTION 4 - CONTROL COMPONENTS
4-14 – JLG Lift – 3121231
Service Programming Mode - (Level-2)
In the Service Programming Mode the following items are
shown on the main menu:
• Reset Timers • EEPROM Defaults
• Program • OSS Sensor
• Tilt Sensor
NOTE: There are two production modules available at this
time, one for North/South American and European
languages, and one for Asian languages. All pro-
grammable items between these modules are identi-
cal with the exception of language selection.
Reset Timers
This setting displays five (5) timers as described following:
• Trip Time: This timer displays total accumulated hours
since last trip timer reset. This is the hour meter reading
displayed on the Ground Control Module LCD Display
during normal machine operation.
• Traction Time: Displays the amount of accumulated
DRIVE hours on the machine’s current drive compo-
nents.
• Lift UP Time: Displays the amount of accumulated time
the machine has operated the Lift UP function.
• Lift DOWN Time: Displays the amount of accumulated
time machine has operated the Lift DOWN function.
• Total Time: Displays the total amount of time accumu-
lated by the Traction, Lift UP and Lift DOWN Timers.
Of these five (5) timers, only the Trip Timer can be RESET
back to zero (00000.0).
• Brush Wear Sensor Timer: This timer must be reset
after the drive motor brushes are replaced and the
brush wear sensors are repositioned. When reset the
display will go from WORN to a blank display. Also the
25 hr./10 second countdown will stop and normal
machine operation will resume.
Program
Allows service personnel to program the Level-2 and
Level-3 items shown in Table 4-1.
Tilt Sensor
Allows service personnel to reset the Ground Control
Module’s internal digital Tilt Sensor to zero (0.0) degrees
in both the X and Y axis.
ZEROING THE TILT SENSOR REQUIRES THE MACHINE TO BE
RESTING ON A SURFACE CHECKED WITH A DIGITAL LEVEL
MEASURING WITHIN 0.0 DEGREES LEVEL IN BOTH THE X AND Y
AXIS DIRECTIONS.
NOTE: When entering this mode the LCD will display in real
time the current X and Y degree readings of the tilt
sensor. The reading being displayed is based on the
previous zero setting and may not reflect level of the
machines current resting surface.
1. Position the machine on a level surface verified level
in both the X and Y axis with a digital level.
2. Select "Zero Tilt Sensor" from the menu and press
the Brake Release button.
3. The current tilt sensor readings are displayed. To
zero both the X and Y direction sensor setting to the
machines’ present resting surface, press the Brake
Release button.
4. Select "Back to Main Menu" and press the Brake
Release Button.
5. Power machine off and begin operation.
EEPROM Defaults
Resets programmable settings to factory default settings
for 10MSP and 15/20MVL/MSP models.
NOTE: New replacement Ground Control Modules are
shipped with the EEPROM Defaults set up for 15/20/
MSP/MVL model machines. If a the new replace-
ment module is installed on a 10MSP model, the
EEPROM Defaults must be reset to the 10MSP
model EEPROM Defaults.
Select "EEPROM Defaults" from the menu and press the
Brake Release button. Select the CORRECT machine
model, then push Brake Release button to accept. Power
machine off and begin operation.
OSS Sensor
Displays current Obstruction Sensor System status
(Detection - YES/NO). Also if an object is detected, the
sensor(s) detecting the object and distance the object is
from the sensor is displayed.
OSS Sensor LCD Display Mode
1. Detection Indicator - Yes/No 3. Object distance from sensor
2. Sensor numbers 4. Signal strength
Note: This screen can be viewed while another person performs
the transducer sensor check, see Section 4.9.
