Fault Output

Pins 1 and 2 can be configured as a fault-output pair. The Fault Output function enables a fault
condition to generate a protection fault signal from the
Both pins 1 and 2 are dedicated to this function. Pin 1 is the Fault output; pin 2 is the common for pin 1.
This provides for an optically-isolated output. The polarity of pin 1 can also be configured. When the
pin polarity is positive, a fault condition causes the isolated output to conduct. Note that the Fault
output signal remains latched until the fault condition is removed and the protection circuit is cleared
using the OUTput:PROTection:CLEar
Pin 2's selected function is ignored. Connect Pin 2 to the ground of the external circuit.
To configure the Fault Output function:

Inhibit Input

Pin 3 can be configured as a remote inhibit input. The Inhibit input function lets an external inhibit
signal disconnect all input channels from the cells. The Inhibit input is level triggered. The signal
latency is 5 microseconds. Pin 8 is the common for pin 3. Use the
specify the following Inhibit input modes: Latching, Live, or Off.
