GTS Mode Operation
When in GTS mode, the control board will respond as follows based on the generator AUTO/OFF/MANU- AL switch position.
OFF — The generator will not start and run in this position.
MANUAL — The control board will start and run the generator whenever the switch is in the manual posi- tion.
AUTO — The control board will monitor the
NOTE:
If the generator is installed in conjunction with an engineered GTS type transfer switch, refer to the applicable transfer switch manual for exact oper- ating parameters and timing sequences.
For proper battery charger operation, it will be nec- essary to supply a fused 240VAC utility fed supply to terminals N1 and N2 in the control panel.
DANGER
With switch set to AUTO, engine can crank
!and start suddenly without warning. Such automatic start up normally occurs when utili- ty source voltage drops below a
3.2.2 FAULT INDICATOR LEDS
(SEE CHART ON PAGE 14)
These LEDs turn ON when one or more of the follow- ing engine faults occurs and the engine shuts down.
•Low Oil Pressure
•Overcrank
•Low Battery
•Overspeed/Engine Speed Signal Fault
•High Coolant Temperature/Low Coolant Level
See Section 1.7 for further explanation of engine pro- tection functions.
3.2CONTROL CONSOLE
COMPONENTS
The components of a home standby generator control console (Figure 3.1) are as follows:

3.2.3 15 AMP FUSE
This fuse protects the control console’s DC control circuit against electrical overload and is located inside the control panel. If the fuse has melted open because of an overload, engine cranking and startup cannot occur. If the fuse needs to be replaced, use only an identical

3.2.1 AUTO/OFF/MANUAL SWITCH
Use this
•Set the switch to AUTO for fully automatic opera- tion. See “Automatic Operation” (Section 3.5).
•Set switch to MANUAL position to crank and start the generator engine.
•Set switch to OFF position to shut down an oper- ating engine. With OFF selected, operation will not be possible.
3.2.5 SET EXERCISE TIME SWITCH
This switch allows programming the generator to start and exercise automatically. “See Weekly Exercise Cycle.”
