3.6.8 Remote Inhibit – J22-36 / J22-27
The Remote Inhibit input J22 pin 36 can be used to open and close the output relay of the AC
power source. This input overrides the state of the output relay programmed from the front panel
or the bus. It may be used for safety interlock purposes.
The default level for remote inhibit is a logic low or contact closure between pin J22-36 and pin J22-
27 (D COM). This will cause the output voltage to be programmed to 0.0 volts and the output relays
to open.
The mode of operation of the remote inhibit can be changed using the Output mode bus command.
This command selects the mode of operation of the Remote Inhibit protection. The following
modes can be selected:
LATChing A TTL low at the RI input latches the output in the protection shutdown state,
which can only be cleared by OUTPut:PROTection:CLEar.
LIVE The output state follows the state of the RI input. A TTL low at the RI input turns
the output off; a TTL high turns the output on.
OFF The instrument ignores the RI input.
The RI output state is saved at power down. The factory default state is LIVE.
For details on programming the remote inhibit function, refer to the iX programming manual (P/N
7000-982).
