24 Section 2 Generator Set Operation
AC Sensing Lost. In Auto mode, generator
output AC sensing is lost. Starts 10 seconds
after crank disconnect.
Warning: after 1 second if no output detected
after crank disconnect.
Shutdown: after 3 seconds if voltage was
present and then lost.
Accessory Power Overload. An over current
fault (short circuit) on the accessory controller
power output.
High generator current has been detected. The
generator set shuts down to protect the
alternator from damage caused by overheating
the windings. (38RCL only)
Ats Communication Error. Warning is displayed
if RXT interface connection is lost. See
Section 2.6.3.
ATS Phase Rotation Mismatch. Transfer switch
phase rotation does not match. ATS will not
transfer.
Auxiliary Input. An optional customer-connected
input is closed. (Digital input from optional PIM.)
Battery charger fault. Input to PIM from an
external battery charger (not the built-in battery
charger).
Engine starting battery voltage rises above
125% of the battery voltage setting for more than
10 seconds. Inhibited during the engine crank
cycle.
Clears when the battery voltage returns to an
acceptable level.
Engine starting battery voltage falls below the
battery voltage setting (typically 12.5 volts) for
more than 90 seconds when the engine is not
running. Inhibited during the engine crank cycle.
Clears when the battery voltage returns to an
acceptable level.
Engine CAN communications fault.
Engine coolant temperature exceeds the
maximum temperature for more than 5 seconds.
Function becomes active after crank disconnect.
The engine ECM indicates low oil pressure for
more than 5 seconds. Function becomes active
30 seconds after crank disconnect (30 second
inhibit).
Note: The low oil pressure shutdown does not
protect against low oil level. Check the engine
oil level regularly as recommended in Section 4.
Engine speed exceeds 115% of the normal
running speed for more than 0.3 seconds.
Engine speed drops below 85% of the normal
running speed for more than 3 seconds.
