• State of MOSFET that drives hydraulic pump
commands (if MOSFET is shorted, motherboard
can detect it and turn OFF power to pump).
4. Master control board sends following signals to
power supply controller:
• Signal to turn bar graph ON and OFF.
• Command MOSFET to conduct power to pump
(driving with PWM signal).
5. 230 V Power Supply Variation:
The 120 V power supply shows the battery
charge level on the bar graph when on battery
power. But, the 230 V power supply only
shows the battery charge level on the bar graph
when the system is operating on facility (ac)
power. When the system is operating on
battery power, the Hand Control icon indicates
the battery charge level in three stages: Full,
Half and Empty.
