RY8 Relay (GS and RN1 only)
The RY8 is energized (COM and N.O. contacts remain closed) only
during the 25D Max Cranking Seconds. This is usually wired to the
starter solenoid (relay) of the generator engine. The RY8 relay energizes
after an initial 25C Set Pre Crank Seconds delay period or de-energizes
once the inverter senses AC voltage above 80 Vac on its AC2 input
terminal.
If the generator does not start, RY8 will energize again after a 25E Post
Crank Seconds delay period. The inverter attempts to start the generator
up to six times.
Guidelines for setting this menu item:
• If the required voltage level is not reached, relay RY7 closes (in the
GS mode) to stop the generator before another attempt is started. This
reduces the chance the starter motor will engage on a spinning
generator engine. This protection is inherent in the RN1 mode.
RY8 Relay (RN2 only)
The RY8 relay remains energized (COM and N.O. contacts remain
closed) during the 25D Max Cranking Seconds. This is usually wired to
the starter solenoid (relay) of the generator engine. This relay energizes
after an initial 25C Set Pre Crank Seconds delay period. The inverter
attempts to energize RY8 (start the generator) only once.
