Menu Item Descriptions

25B Gen Warm-up Seconds/minutes
This menu item sets the number of seconds or minutes the generator is
allowed to warm up before the load is connected and the battery charger
started. If the generator is located in a cold location, a longer setting may
be required.
25C Pre Crank Seconds
This menu item sets the number of seconds the system delays engaging
RY8 (the crank signal relay) once relay RY7 is engaged. Also if GS is
selected from 25A RY7 Mode, this setting will allow selection of the
delay time between RY7 disengaging and RY8 engaging. If this number is
even, the delay is immediate. If the number is odd the delay is three
seconds.
Refer to “Automatic Generator Control” on page 7–24 for more
information. This period may also be the amount of time the glow plug is
ON if it is connected to the automatic-start system.
25D Max Cranking Seconds
This menu item sets the maximum number of seconds the starter is
cranked during the starting sequence by engaging relay RY8.
Guidelines for setting this menu item:
• If GS or RN1 (RY7 Mode) are selected, RY8 will disengage when the
generator AC output is sensed (> 80 Vac) on the inverters AC2 input.
• If RN2 (RY7 Mode) is selected, RY8 will stay engaged (crank) for the
entire time set in menu 25D Max Cranking Seconds.
25E Post Crank Seconds
This menu item sets the number of seconds after an unsuccessful crank
attempt, the system will delay before attempting another auto-start
sequence. If the generator has not started, this sequence is repeated up to
five times.
This period is provided to allow the starter motor to cooldown. It can also
allow generators with built-in warm-up delay contactors to provide AC
output before the inverter attempts a re-crank cycle.
