NOTE : The maintenance timer displays "Service Required" when this time expires. This message is only displayed the next
time the controller enters the RUN mode. If the timer expires when the controller is in the RUN mode the message is not
displayed.
4.6 AC Monitor
The controller has the ability to monitor AC voltage from a generator. The following sections are used to configure settings
associated with AC monitoring.
4.6.1
Generator Voltage
The following settings are used to configure the controller's response to voltage measurements.
(AC Monitor > Genset Voltage menu)

3-Wire
Single
The wiring configuration of the generator. Disable will disable AC
voltage and AC frequency sensing and display.
2-Wire Single: One 120VAC L-N. Use phase A.
3-Wire Single: 120/240VAC systems. Use phases A and B.
3-Wire 3-Phase: Three phase delta without a ground.
4-Wire 3-Phase: Three phase Wye system. Center taped ground.
4-Wire Delta: Delta with a ground. The high leg is phase B. For
example if A-N and C-N read 120VAC then B-N will read 208VAC.
Selecting Auto Selection will use the Voltage Select switched inputs to
determine the wiring configuration.
This setting also enables the AC Frequency monitoring and display.
