OPERATION

GENERATOR STOP COOL DOWN PERIOD

When the automatic generator stop system is used to stop the generator, the generator is disconnected from the inverter first by opening the AC relay inside the inverter. This allows a very clean transition from the generator to the inverter. The STOP signal is provided immediately if the generator is manually shut off from the Control Panel. If the generator is shut off automatically the generator will be allowed to run for an additional 40 seconds before the STOP signal is provided. This allows the generator to cool down before it is turned off. This is very important for turbocharged generators as it allows cooler oil to reach the turbo. If the generator does not stop after the 40 second cool down period when the stop signal is sent, then the inverter will reconnect to the AC source and remain connected as long as it is available.

If the generator is stopped manually from the Control Panel, the generator is stopped immediately with no cool down.

GENERATOR ERROR CAUSES

The red ERROR LED indicator will blink slowly if one of the following generator errors occurs:

•GEN UNDER/OVER SPEED: Indicates that the generator has synchronized with the inverter/charger but the frequency is not well adjusted (63 - 67 on the high-end or 53 - 57 on the low end).

•GENERATOR START ERROR: The automatic control system will attempt to start the generator 5 times by closing the starting relay RY8 for up to the MAX CRANKING SECONDS setting, or the inverter senses an AC voltage above 80-volts AC on the AC HOT IN 2 terminal. Once the inverter senses 80 volts AC on the AC HOT IN 2 terminal, after a half-second delay, RY8 opens. After successfully running for 5 minutes, the start attempts counter resets to zero. If the generator dies within the 5-minute period of being started, the inverter will attempt to restart the generator. An unsuccessful run is considered a failed start attempt. After 5 start attempts, the ERROR LED illuminates and the generator control system shuts down. If the generator dies after successfully running for 5 minutes, the start attempt counter will be reset to zero and the inverter will only restart the generator if the auto start voltage setting or load amps AC setting is reached for the required time delay period.

•GENERATOR SYNC ERROR: Indicates that the generator was running but was not operating within the voltage and frequency tolerances and not able to connect (out of sync), or the unit can not maintain synchronization (AC voltage or frequency is out of tolerance).

•GEN MAX RUN TIME ERROR: Indicates that the generator ran for a period of time that exceeded the SET MAXIMUM RUN TIME setting. This setting is intended to indicate excessive generator operation if the system has not been able to fully charge the battery. Operating heavy loads while charging, an unstable generator or even low electrolyte levels in the battery can cause this. This may also occur with systems that have very large batteries, requiring long charge periods, or systems with small generators with limited battery-charging ability. If the default value results in repeated error conditions, increasing the SET MAXIMUM RUN TIME menu item setting may be necessary for your application. When using the automatic generator control system to complete a equalization cycle, the additional time required for the EQ cycle should be considered in order to prevent reaching the SET MAXIMUM RUN TIME menu item setting and causing a GEN MAX RUN TIME ERROR. This is an advisory error only and does not stop the generator.

To clear a generator start error, access the SET GENERATOR menu item by pressing the green GEN MENU button and move the cursor from AUTO or ON to OFF in the SET GENERATOR menu item. This clears all the generator error conditions and resets the start attempts counter.
