14 Main Driver Off
If the FET that controls the closing of the solenoid is
not
energized when it should be, a
main driver off
fault
is detected by the speed controller.
15 Relay DNC
If the external Zero Speed Detect Relay contacts do not close, a
relay dnc
is detected.
16 Keyswitch SRO
If the key switch has always initially been seen in the OFF position after the controller is powered up before
driving is allowed to commence, a
key switch sro
fault is detected.
17 Current Sense
If there are problems with the armature current sensor circuitry, a
current sense
fault is detected.
18 M- Shorted
If an uncontrolled current path is detected from the motor to B- (bypassing the MOSFETs), an
M- shorted
fault
is detected.
20 Driver Overcurrent
If the current on the relay driver exceeds 120 mA, or the current on the main driver exceeds 6A, a
driver over-
current
fault is detected.
21 Precharge Fault
If the internal precharge circuit fails, or there is a short between the B+ and B- terminals, a
precharge
fault is
detected.
22 Field Missing
If the speed controller is operating at a duty cycle of greater than 90% (almost full speed) and the field current
is less than 3 amps, a
field missing
fault is detected by the speed controller.
23 Relay Driver On
If the relay driver has been commanded to turn OFF, but remains on, a
relay driver on
fault is detected.
24 HW Failsafe
If the speed controller detects a failure of the armature drive FETs or circuitry, an
hw failsafe
fault is detected.
25 Incorrect Password
If an incorrect attempt is made to activate Mode 2 by entering Code A, Code B, Code C, an
incorrect pass-
word
fault is detected.
26 Circuit BRKR Open
If the circuit breaker element in the Zero Speed Detect circuit is blown, or not wired to the controller, a
circuit
brkr open
fault is detected.
27 Max Password Tries
The
max password tries
fault is declared when the incorrect password fault has been declared several times.
In the event that the
max password tries
fault is indicated, the speed controller must be removed and shipped
to Club Car before it can ever be placed in Mode 2.
See Code A, Code B, and Code C, Section 18,
See also Password Tries on page 12-5.
29 Relay DRVR Off
If the Zero Speed Detect relay driver FET remains in the OFF state when commanded to switch on, a
relay
drvr off
fault is detected
.
