FREQUENCY adjust knob
Potentiometer permits adjustment of generator set frequency.
SYNC MODE switch
Four-position switch used to control TQG paralleling operations and modes. If
not in paralleling mode, switch should be OFF.
Disables synchronizing and synchroscope functions.
With PARALLEL switch closed (up), GSC brings TQG in synchronization with
paralleling bus and holds it there indefinitely. AC CIRCUIT INTERRUPTER
switch is enabled and operator can connect TQG to others. Automatic voltage
Provides complete automatic paralleling with another unit.
Bus Live: GSC brings TQG into sync with load bus and sends a signal to
connect TQG to load bus.
Bus Dead: GSC adjusts voltage to programmed value and connects output to
With PARALLEL switch closed (up), manual paralleling mode allows operator
to adjust voltage, frequency, and phase of TQG to match load bus. When TQG
is synchronized with bus, operator brings TQG on line by closing AC
CIRCUIT INTERRUPTER switch.
VOLTAGE adjust knob
Potentiometer control permits fine adjustment of generator set voltage.
Two-position toggle switch. Controls dead bus monitoring and paralleling of
load sharing modules.
Activates paralleling circuits (up). Used when placing TQG in parallel mode.
Bus is monitored by relays that will not allow generator output to be connected
to load if there is power on load bus. Load sharing module is connected to
paralleling cable connector for paralleling in ISOCHRONOUS mode.
Deactivates paralleling circuits (down). Generator is operating independently of
other generators. GSC monitors bus and load can be connected automatically
or enabled for operator connection. Load sharing module is disconnected from
paralleling cable connector output.
Alarm will sound if an overcurrent, an overload, or a low fuel condition exists.
Refer to Table 3.
DVR provides excitation to control and regulate generator voltage. Refer to
Table 4 for controls and indicators.
