FAULT CODE
The 1243GEN2 controller has two fault outputs, at Pins 2 and 3, which can be
used to transmit signals to LEDs located on the display panel or on any remote
panel. The fault outputs can be configured to display faults in two different
formats: Fault Code format or Fault Category format. The fault code parameter
is used to select the preferred format.
In Fault Code format (fault code parameter On), the two fault outputs
operate independently. When a fault is present, the Fault 1 driver (Pin 2)
provides a pulsed signal equivalent to the fault code flashed by the controller’s
built-in Status LED; the fault codes are listed in Table 8, page 74. The Fault 2
driver (Pin 3) will steadily pull low (to B-) when any fault is present, and can be
used to drive a fault/no-fault LED. When no faults are present, the Fault 1 and
Fault 2 outputs will both be high.
In Fault Category format (fault code parameter Off), each combination
of the two fault outputs defines one of four fault categories. Table 6 lists the
possible faults included in each category.
Note: Alternatively, Pin 2 can be used as a pump meter input, and Pin 3
can be used to interface an external auxiliary enable circuit; see fault output
wiring, page 14.

FAULT FAULT 1 FAULT 2
CATEGORY OUTPUT OUTPUT POSSIBLE EXISTING FAULTS
0 HIGH HIGH (no faults present)
1 LOW HIGH Current Shunt, HW Failsafe, M- Shorted,
Throttle Wiper High or Low, Emergency Reverse
Wiring Fault, Field Winding Open, Contactor Coil
or Field Shorted, Main Contactor Welded or
Missing
2 HIGH LOW Low Battery Voltage, Overvoltage,
Thermal Cutback
3 LOW LOW Anti-Tiedown, HPD, SRO, Expired Service Timer
or Disable Timer, Motor Too Hot
BDI LOCKOUT
When the BDI lockoutiparameter is programmed On, the Fault 2 output (at
Pin 3) can be used as an interface to an external auxiliary enable circuit. When
BDI%=0, the Fault 2 output will be high; when BDI%≥1, the Fault 2 output
will be low.
When BDI lockout is programmed Off, the Fault 2 output is determined
by the setting of the Fault Code parameter.
