From the front panel:
1. Press Utilities > I/O Config > Digital IO to access the Digital I/O window.
2. Press Pin 1 to configure Pin 1.
3. Press Function and select Fault Out. Press Back to return to previous page.
4. Configure the polarity for each of the pin. Press Polarity Pos to select Positive and Polarity Neg to select Neg-
ative.
From the remote interface:
To configure the pin function:
DIG:PIN1:FUNC FAUL
To select the pin polarity:
DIG:PIN1:POL POS
DIG:PIN1:POL NEG
Inhibit input
Pin 3 can be configured as a remote inhibit input. The Inhibit Input function lets an external input signal control the
load input state of all the input channels in the load. The polarity of pin 3 can also be configured. The load input is
level triggered. The signal latency is less than 450 microseconds. Maximum time required for all the input channels
to start to turn off is 45 ms. Pin 4 is the common for pin 3.
The following non-volatile inhibit input modes can be programmed:
LATChing - causes a logic-true transition on the Inhibit input to disable the load input. The load input will remain
disabled after the inhibit signal is received.
LIVE - allows the enabled load input to follow the state of the Inhibit input. When the Inhibit input is true, the load
input is disabled. When the Inhibit input is false, the load input is re-enabled.
OFF - The Inhibit input is ignored.
From the front panel:
Configure Pin 3 as a remote inhibit input:
1. Press Utilities > I/O Config > Digital IO to access the Digital I/O window.
2. Press Pin 3 to configure Pin 3.
3. Press Function and select Inhibit In to configure Pin 3 as a remote inhibit input. Press Back to return to pre-
vious page.
4. Configure the polarity for Pin 3. Press Polarity Pos to select Positive and Polarity Neg to select Negative.
Alternatively, you can configure Pin 3 as a remote inhibit input by pressing Input Settings > Output Inhibit > DIO Pin
3 INH. In this setting, the polarity is set to Positive by default.
