Note: The GSC+ can be programmed to override the
shutdown for low oil pressure and high water
temperature faults. When the operator overrides the
shutdown faults, the GSC+ responds to the faults as
though the faults are alarm faults. The corresponding
dedicated shutdown indicator is ON
CONTINUOUSLY and will not be flashing. The
engine continues to run and can be restarted when
necessary. When the dedicated shutdown indicator is
ON CONTINUOUSLY, the setpoint for shutdown has
been exceeded, but the GSC+ is programmed to
override the shutdown fault. The GSC+ does not treat
the shutdown fault as a shutdown fault. The GSC+
treats the shutdown fault as an alarm fault. At the
factory, the GSC+ is programmed to treat a low oil
pressure fault and a high water temperature fault as
shutdown faults. The operator or the service
technician must decide to override these shutdown
faults. The operator or the service technician must
program the GSC+ to treat the shutdown faults as
alarm faults. For programming procedures, refer to
the Systems Operation, Testing and Adjusting,
RENR2484, “Electronic Modular Control Panel II+
(EMCP II+)”.

Display Area of the GSC+
(29) Upper display
(31) Lower display
(32) The power meter key
(33) The AC meter key
(34) The engine meter key
The display consists of the upper display and the
lower display. Both displays are used for
programming functions when in service mode. For
more information, see the Systems Operation,
Testing and Adjusting, RENR2484, “Electronic
Modular Control Panel II+ (EMCP II+)”.
Upper display
The EMCP II+P upper display (29) displays voltage
and frequency. The voltage and frequency alternate
between the generator output and the bus. The word
“bus” or “gen” appears in the right side of the window.
This word indicates which parameter is displayed.
Several options are available on the upper display for
AC metering. These options can be viewed one at a
time by pressing the AC meter key (33) on the
keypad. The options are listed below.
• Average voltage, generator frequency and total
current
• Line to line voltage, generator frequency and line
current for any one phase
• Line to line voltage for all three phases at once
• Line current for all three phases at once
Note: When total current increases above “9999A” ,
the GSC+ will show current in “kA” units.
• Line to neutral voltage for all three phases at once
Upper display (29) is also used to show the various
fault codes for system faults. For more information on
fault codes, see the Systems Operation, Testing and
Adjusting, RENR2484, “Electronic Modular Control
Panel II+ (EMCP II+)”.
Note: Line to neutral voltages are not shown when
the setpoint P032 is set to 1 for delta generator sets.
Lower display
The EMCP II+P lower display (31) displays the
synchronoscope. This unique display allows a
simultaneous visual indication of both frequency and
phase of the generator set, in reference to the bus.
Additionally, the three spare indicator lamps are used
to indicate the synchronization status.
The lower display (31) shows values for power
metering, engine parameters, and the relay status.
The left side of the lower display (31) serves as a
power meter for the generator set. The following
functions will scroll automatically.
• Total real power (kW)
• Total reactive power (KVAR)
• Percentage of rated power (%kW)
