FAULT CODE
The 1243
GEN
2 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 dif-
ferent 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.
