Undervoltage, supply voltage,
current sensor (-15V)
[FAULT SR-DRIVE (13)]
Control board overvoltage
(+24V)
Faulty cabling from emergency OFF push
button to control board.
Check connection between control
board J5, terminal 4, and control board
J3, terminal 9.
[FAULT SR-DRIVE (14)]
Control board undervoltage
(+24V)
Ribbon cable faulty between control board
(PCB94) and gate drive board (PCB95).
Check ribbon cable between control
board (PCB94) and gate drive board
(PCB95).
Control or gate drive board faulty.
Otherwise contact Gardner Denver
Service.
[FAULT SR-DRIVE (15)]
Motor overcurrent
Motor incorrectly connected or faulty motor
cables.
Check connection of motor phases at
power electronics.
Motor insulation fault.
Check motor cables for damage.
Current sensor cabling or plug faulty.
Check cabling and plug of control
centre as far as control board J10.
Control or gate drive board faulty.
Otherwise contact Gardner Denver
Service.
[FAULT SR-DRIVE (16)]
Motor overcurrent, phase B
[FAULT SR-DRIVE (17)]
Motor overcurrent, phase C
Power monitoring is not being used for
phases B or C. The occurrence of this
malfunction points to a fault on the control or
gate drive board.
Contact Gardner Denver Service.
