‹3.2.6 SYSTEM READY LED

The System Ready LED (green) has two main pro- poses. First, the LED will be ON when the AUTO/OFF/MANUAL switch is in the AUTO position, utility is present, and there are no system alarms. This ON state indicates the system is fully ready for automatic operation.

The system ready LED will be OFF when the switch is in the manual or OFF positions.

The system ready LED is also used to indicate the presence of utility sensing at the PCB when the switch is either in the AUTO or MANUAL modes. The LED will flash at the rate of 1/2 second on, 1/2 second off if the utility sensing level is below the transfer back threshold.

This secondary function is only available with dip switch two in the OFF position (ATS - automatic transfer switch application).

3.3MANUAL TRANSFER AND

START-UP

To transfer electrical loads to the Standby (EMER- GENCY) power source side and start the engine man- ually, refer to the Owner’s Manual of the particular transfer switch.

3.4ENGINE GOVERNOR

ADJUSTMENTS

Engine speed governing is also controlled by the engine control board. The engine governor has been set by the factory during final testing of the generator and should not be adjusted.

If, however, adjustments are necessary, the following procedure should be followed (Figure 3.2 and Section 3.8):

1.Move dip switch 8 to the test mode (OFF posi- tion).

2.Set all three potentiometers (pots) fully counter- clockwise.
