RY7 and RY8 Timing Diagram
The generator auto-stop sequence is initiated if:
1) The time set in 24C QUIET TIME BEGIN has been reached or passed. This setting will disable 2, 3, and 4 start-scenarios below.
2) If the battery voltage has been held at the 12B BULK VOLTS DC setting for the time set in 12H MAX BULK/EQ TIMER H:M or if
the voltage has reached the 12F BULK DONE AMPS AC setting.
3) If the load amps remains below the 26A LOAD START AMPS AC setting and remains longer than the period set in 26C LOAD
STOP DELAY MINUTES.
4) If the time set for the generator to stop in 24B GEN RUN TIME STOP H:M is reached.
5) If the time set in 24H RN2/MAX GEN RUN H:M is reached and 25A RY7 MODE is set to RN2.
The generator manual-stop sequence is initiated if OFF is selected in 02A GENERATOR (OFF AUTO ON).
The next generator auto-start sequence is initiated.
(RN1 and GS modes will make six attempts to start the generator.
RN2 will only make one attempt to start the generator.)
The Generator auto-start sequence is initiated if:
1) The time set in 24D QUIET TIME END has been reached or passed.
2) If the battery voltage remains below the 11C LOW BATTERY CUT OUT VDC setting for the required period of time or if below the READ
LBCO 30 SEC START VDC setting for 30 seconds.
3) If the load amps reaches the 26A LOAD START AMPS AC setting and remains longer than the period set in 26B LOAD START DELAY
MINUTES.
4) If the time set for the generator to run in 24A GEN RUN TIME START H:M is reached.
The manual generator start sequence is initiated if generator is manually turned on via SET GENERATOR to ON.
The generator will stop immediately (no cooldown period) if an inverter fault is
detected or if OFF is selected in 02A GENERATOR (OFF AUTO ON).
