Fault Output
Pins 1 and 2 can be configured as a fault-output pair. The polarity of pin 1 can also
be configured. Pin 1 is the Fault output; pin 2 is the common for pin 1. Note that
pin 2 must also be connected to pin 8.
The Fault output function enables a fault condition on any channel to generate a
fault signal on the digital control port. The following conditions will generate a fault
event: over-voltage, over-current, over-temperature, inhibit signal, power-fail
condition, or on some models, a power-limit condition.
Both pins 1 and 2 are dedicated to this function. This provides for an
optically-isolated output. Pin 2’s function is ignored.
Note that the Fault output signal remains latched until the fault condition is
cleared. You must also clear the protection circuit.
