Operating Instructions

shutdown alarm that is preventing diesel mode operation. If the
unit is switched back to diesel mode, the alarm again become a
diesel mode shutdown alarm and prevents unit operation.
In the same manner, if a shutdown alarm occurs that affects
only electric mode operation and the unit is switched to diesel,
the electric mode shutdown alarm becomes a diesel mode log
alarm to allow diesel mode operation. If the unit is switched
back to electric mode, the alarm reverts to an electric mode
shutdown alarm and prevents unit operation. If the unit is
configured for electric to diesel Auto-Switch, it automatically
starts and runs in diesel mode if an electric shutdown occurs.
