Interconnect System Self Test Feature (follow the
Upon power up, this controller will go through a system self test which will check for the presence of utility voltage on the DC circuits. This is done to prevent damage if the installer mistakenly connects AC utility power sense wires into the DC terminal block. If utility voltage is detected, the controller will display a warning message and lock out the generator, preventing damage to the controller. Power to the controller must be removed to clear this warning.
Utility voltage must be turned on and present at the N1 and N2 terminals inside the generator control panel for this test to be performed and pass.
NOTE:
DAMAGE CAUSED BY MISWIRING OF THE INTERCONNECT WIRES IS NOT WARRANTABLE!
This test will be performed each time the controller is powered up.
Upon first power up of the generator, the display interface will begin an installation assistant. The assistant will prompt the user to set the minimum settings to operate. These settings are simply: Current Date/Time and Exercise Day/Time. The maintenance inter- vals will be initialized when the exercise time is entered.
The exercise settings can be changed at any time via the "EDIT" menu (see Appendix, "Menu System").
If the 12 volt battery is disconnected or the fuse removed, the Installation Assistant will operate upon power restoration. The only difference is the display will only prompt the customer for the current Time and Date.
IF THE INSTALLER TESTS THE GENERATOR PRIOR TO INSTALLATION, PRESS THE “ENTER” KEY TO AVOID SETTING UP THE EXERCISE TIME. THIS WILL ENSURE THAT WHEN THE CUSTOMER POWERS UP THE UNIT, HE WILL STILL BE PROMPTED TO ENTER AN EXERCISE TIME.
SETTING THE EXERCISE TIMER
This generator is equipped with an exercise timer. Once it is set, the generator will start and exercise every seven days, on the day of the week and at the time of day specified. During this exercise period, the unit runs for approximately 12 minutes and then shuts down. Transfer of loads to the generator output does not occur during the exercise cycle unless utility power is lost.
LOW SPEED EXERCISE
The standard start sequence will be initiated.
•All 1800 rpm units will exercise at 1400 RPM
•All 3600 rpm units will exercise at 1800 RPM
If utility is lost during exercise the controller will do the following:
•Wait for the “line interrupt period” for utility to return. If utility returns within the “line interrupt period”, continue to exercise at low RPM.
•If utility is still lost after the “line interrupt period”, run the engine up to normal RPM and transfer the load. At this time the con- troller will exit the exercise routine and assume full automatic operation.

OPERATION
This system is intended to supply standby power in the event of a utility failure. The control system will monitor the utility voltage to determine if
AUTOMATIC TRANSFER OPERATION
To select automatic operation, do the following:
1.Make sure the transfer switch main contacts are set to their UTILITY position, i.e., loads connected to the utility power source.
2.Be sure that normal UTILITY power source voltage is avail- able to transfer switch terminal lugs N1 and N2 (Refer to the Electrical Data section).
3.Set the generator’s AUTO/OFF/MANUAL switch to AUTO.
4.Set the generator’s main circuit breaker to its ON (or CLOSED) position.
With the preceding steps complete, the generator will start auto- matically when utility source voltage drops below a preset level. After the unit starts, loads are transferred to the standby power source. Refer to the Sequence of Automatic Operation section.
