The following basic parameters, at least, they are defined (see parameters "Menu Quikset" for
more details):
• #TEETH (number of teeth of the rack (Cummins Engine 127 teeth and 125 teeth Iveco).
• CRANK (set the end of the boot in RPM at 400rpm).
• SPEED (set the nominal speed in RPM which is 1847RPM).
Using the keyboard and the LCD:
• The numeric area displays the value of a selected parameter or parameter running. The
alphanumeric area displays the units for the parameter (for example, 1847 rpm).
• When executed, the EDG, by default, displays the engine RPM in the alphanumeric area and
a bar graph will represent the throttle position. It can switch this view by pressing
ARROW UP OR DOWN ARROW, see the table in Real-time preview on the next
page.
• If the EDG monitor is locked, it can be unlocked by simultaneously pressing and holding the
UP ARROW and DOWN ARROW buttons for 2 seconds. The LOCKED indicator
will be off.
A. Increase the GAIN parameter in "Quikset Menu" to develop instability. Gradually decrease
the GAIN until the return of stability. If not stabilize, let set at 50.
B. Increase the STABILITY parameter in "Quikset Menu" to develop instability. Gradually
decrease the STABILITY to the return of stability. If not stabilize, let set at 50.
C. Increase the DEADTIME parameter (compensation) in the "Quikset Menu" to develop
instability. Gradually decrease the DEADTIME to the return of stability.
D. The settings of parameters GAIN, STABILITY and DEADTIME may require minor
changes after the motor load is applied. Typically, adjustments unloaded reach a satisfactory
performance. A strip chart recorder (oscillographic) can be used to further refine the settings.
Normally leave the standards listed in the table.
If instability can not be corrected or more needed performance improvements, see below the
TROUBLESHOOTING section. In this section, the information can be found regarding the
procedures for troubleshooting.

REAL-TIME PREVIEW
While the engine is running, the EDG displays measured values in real time in the main
display and a bar graph. There are three different screens (see table below). Pressing the UP
ARROW or DOWN ARROW to cyclical change between screens.
OVERSPEED - ON SPEED
When the EDG5500 detects that the engine reaches the speed specified by OVERSPEED
parameter, the EDG will command the speed to 0 RPM and will set 0V at the gateway to the
