Idle Mode
For generators that have the capability of idling at a lower speed than the normal
operating speed the GSC400 controller has an
Idle Mode
feature that suppresses the
warnings and failures for under-voltage, under-frequency, and under-speed. The
GSC400 displays “
Idle Running
” when this feature is enabled.
The controller remains in Idle Mode as long as the
“Idle Mode” digital input
is active.
See Table 15 on page 67 for more information on the digital inputs. If the user desires a
digital output to turn on during Idle Mode, the “Voltage Regulator” digital output can be
used. It is inactive when the controller is in Idle Mode and active when the controller is
not in Idle Mode. See Table 14 on page 64 for more information on the digital outputs.
The output is usually used to turn off the generator voltage regulator but can be used for
any purpose.
For users who have engines that idle during warm-up and/or cool-down (See section 6.5
on page 62 for more information on the Warm-up and Cool-down features.) the “
Warm-
up
” and “
Cool-down
” digital outputs can be tied to the “Idle Mode” digital input via an
external relay (shown in Figure 6 below).
