To Connect The Jlg Control System Analyzer To The Generator; Alarms And Fault Flash Codes - JLG E600 Service And Maintenance Manual

To Connect the JLG Control System Analyzer
to the Generator
The JLG Control System Analyzer can be used to monitor
generator settings and conditions. Connect the analyzer
as follows:
1. Connect the four pin end of the cable supplied with
the analyzer, to the connector behind the ground
control module located on the left side of the
machine next to the ground control station and con-
nect the remaining end of the cable to the analyzer.
The ground control module contains the settings for
the generator.
NOTE: The cable has a four pin connector at each end of
the cable; the cable cannot be connected back-
wards.
2. Power up the Analyzer by pulling out the ground sta-
tion EMS and positioning the Generator Enable
switch on the platform control box to the "on" posi-
tion. Refer to Figure 3-34., Generator System Ana-
lyzer Flow Chart
