INITIAL START SETUP MENU
The facing page shows a block representation of
the INITIAL START SETUP menu.
CAUTION
Selecting this menu resets all oper-
ating parameters to the default values for the
selected set. All previously selected setup and
adjustment settings will be lost. Therefore, this
procedure must be performed by technically
qualified personnel only.
This menu appears on the digital display when the
PCC has not been set up for use with a generator
set during factory test, or the digital board was re-
placed in the PCC.
When this display is showing, you must go through
the Initial Start Setup menu to select the operating
parameters for the generator set. These include
whether the set will be used for Prime Power or
Standby use, the Model Number of the generator
set, and its operating frequency and output voltage.
These choices must be saved into the PCC’s read-
only memory before the PCC will accept changes
made to other menus.
If the PCC is already set up to operate with a specific
generator set, this menu will not appear when power
is applied. To reset the control and display the Initial
Start Setup menu, you can press RESET, MENU, and
PHASE SELECT buttons at the same time.
If you choose to do this, the governor/regulator ad-
justments and the setup options will be reset to the
default settings (including the editable customer
fault messages). Display calibrations (volts, amps,
PF and coolant temperature) are retained (not reset).
To make sure correct and complete readjustment of
the PCC, it is suggested that all settings be recorded
before you perform the reset function.
CAUTION
Improper setup, calibration, or ad-
justments can cause equipment malfunction or
damage. Setup, calibration, and adjustment
must be performed by technically qualified per-
sonnel only.
