16With the AUTO/OFF/MANUAL switch at AUTO, the engine shouldcrank and start when the utility source power is turned OFF after a10 second delay. After starting, the transfer switch should connectload circuits to the standby side after a five (5) second delay. Letthe system go through its entire automatic sequence of operation.With the generator running and loads powered by generator ACoutput, turn ON the utility power supply to the transfer switch. Thefollowing should occur:• After about 15 seconds, the switch should transfer loads backto the utility power source.• About one minute after re-transfer, the engine should shutdown.3.1 CONTROL PANEL INTERFACE3.1.1 USING THE AUTO/OFF/MANUAL SWITCH(FIGURE 3.1)With the switch set to AUTO, the engine maycrank and start at any time without warning.Such automatic starting occurs when utilitypower source voltage droops below a presetlevel or during the normal exercise cycle. Toprevent possible injury that might be causedby such sudden starts, always set the switchto OFF and remove the fuses before work-ing on or around the generator or transferswitch. Then, place a “DO NOT OPERATE”tag on the generator panel and on the trans-fer switch.1. “AUTO” Position – Selecting this switch activates fully auto-matic system operation. It also allows the unit to automati-cally start and exercise the engine every seven days with thesetting of the exercise timer (see the Setting the ExerciseTimer section).Figure 3.1 – 8/10/14/17 & 20kWGenerator Control PanelEscapeMAIN FUSEAUTO OFF MANUAL7.5 AMPEnter2. “OFF” Position – This switch position shuts down the engine.This position also prevents automatic operation.3. “MANUAL” Position – Set the switch to MANUAL to crankand start the engine. Transfer to standby power will not occurunless there is a utility failure.3.1.2 SETTING THE EXERCISE TIMERThis generator is equipped with an exercise timer. Once it is set,the generator will start and exercise every seven days, on the dayof the week and at the time of day specified. During this exerciseperiod, the unit runs for approximately 12 minutes and then shutsdown. Transfer of loads to the generator output does not occurduring the exercise cycle unless utility power is lost.INSTALLATION ASSISTANTInterconnect System Self Test Feature (follow the on-screenprompts)Upon power up, this controller will go through a system self testwhich will check for the presence of utility voltage on the DCcircuits. This is done to prevent damage if the installer mistakenlyconnects AC utility power sense wires into the DC terminal block.If utility voltage is detected, the controller will display a warningmessage and lock out the generator, preventing damage to thecontroller. Power to the controller must be removed to clear thiswarning.Utility voltage must be turned on and present at the N1 and N2terminals inside the generator control panel for this test to beperformed and pass.NOTE:DAMAGE CAUSED BY MISWIRING OF THE INTERCONNECTWIRES IS NOT WARRANTABLE!This test will be performed each time the controller is poweredup.Upon first power up of the generator, the display interface willbegin an installation assistant. The assistant will prompt the userto set the minimum settings to operate. These settings are sim-ply: Current Date/Time and Exercise Day/Time. The maintenanceintervals will be initialized when the exercise time is entered (Figure3.1).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, theInstallation Assistant will operate upon power restoration. Theonly difference is the display will only prompt the customer for thecurrent Time and Date.IF THE INSTALLER TESTS THE GENERATOR PRIOR TOINSTALLATION, PRESS THE “ENTER” KEY TO AVOID SETTINGUP THE EXERCISE TIME. THIS WILL ENSURE THAT WHENTHE CUSTOMER POWERS UP THE UNIT, HE WILL STILL BEPROMPTED TO ENTER AN EXERCISE TIME.Operation
