Auto Start Connection for external two wire starting from transfer switch or other controller. Strip the insulation from the remote start wires. Simply press while inserting the wire then release to secure the connection.
Voltage Reconnect and Adjustment
The digital engine controller runs software called voltage auto−detect. Every time the engine is started and after the timer in the Engine Params: Stabil Time has elapsed, the nominal voltage will be detected and locked in. Various set points in the engine controller are then calculated as a percentage of this nominal voltage. For example: The over−voltage set point is set to 110%.
This means that when the unit is providing 208V, the over−voltage set point will lock in at 229V. When the unit is operating in 480V the over−voltage set point will lock in at 528V.
Example: To change the voltage from 208V nominal to 240V nominal, the voltage adjustment must be made before the controller locks in the nominal voltage.
1.Set the Voltage Select Switch to 240/120V position.
2.Start the engine.
3.Immediately adjust the Voltage Adjust for 240VAC nominal before the 20 second timer expires.
4.The new 240V nominal voltage is now locked in.
This procedure must be performed whenever the nominal voltage is changed.
