Version and Displays Menus (Cont.)
DISPLAYS submenus: The DISPLAYS submenus
are intended for qualified service personnel only.
For this reason, a three-digit access code must be
entered before you can proceed to those menus.
Select SETUP/CAL. The display will show the EN-
TER CODE submenu. Enter access code (574) as
previously described in this section.
Select DISPLAYS to proceed to the DISPLAYS sub-
menus. Use the buttons next to the “
” and “” sym-
bols to calibrate the selected voltage, current, PF or
coolant temperature reading. Press the button next
to the “>>” in the display to move to the next adjust-
ment.
“VOLTS L12,” “VOLTS L23,” and “VOLTS L31” refer
to voltages measured from L1 to L2, L2 to L3, and
L3 to L1, respectively.
“PF1, PF2 and PF3” will display N/A when the gen-
erator set is not running.
“COOLANT TEMP R” will display “N/A” if the gener-
ator set has only one sensor. To calibrate coolant
temperature display, a precision resistor (provided
in the engine sensor tool) must be temporally sub-
stituted for the temperature sender. Refer to Cal-
ibration Procedure in this section.
SAVE/EXIT submenu: From the AMPS L3 subme-
nu, press the button next to the “>>” in the display to
move to the SAVE/EXIT submenu. Select SAVE to
save your changes. At the CHANGES SAVED sub-
menu, select EXIT to return to the DISPLAYS/ME-
TERS submenu.
If you select SAVE, the adjustments will be retained
after shutdown, and will be in effect when the set is
restarted. If you select EXIT without saving first, the
adjustments will remain in effect until the generator
set is shut down, but will be reset (and will not be in
effect) when the set is restarted.
