When the above conditions apply, the generator’s controller will
monitor status of the batteries, will turn on automatically when
the battery voltage drops as a result of discharge and will turn off
when batteries are fully charged.
Battery Only Operating Mode
The machine will operate in the battery only mode when the fol-
lowing two conditions apply:
1. Ground Control Emergency Stop Switch is
pulled out (on), and:
2. The switch on the platform control console is
in the Off or Disable position.
In this mode the machine will operate as a conventional battery
operated unit. The batteries can be used until they are fully dis-
charged.
Manual (Charge) Operating Mode
The generator will operate in manual mode always when the fol-
lowing three conditions apply.
1. Ground Control Emergency Stop Switch is
pulled out (on), and:
2. The switch on the platform control console is
in the On or Enable position and:
3. The Manual Charge push button is activated.
Activation of the Manual Charge button will start the engine and
initiate the charging cycle even if the batteries are charged above
the level of automatic start. The operator can initiate the charge
cycle to charge the batteries to the maximum level. The charging
cycle will include finishing phase similar to conventional char-
gers.
