4.9 Remote Inhibit Function
The remote inhibit input on the rear panel can be used to disable the output of the AC source.
This input takes either a low level TTL signal or a contact closure. The mode of operation can be
programmed over the remote control interface using the OUT
P:RI:MODE command. See 7004-
981 programming manual for details.
The following modes are supported.
MODE
OPERATION
LATCHING
A TTL low at the RI input latches the output in the
protection shutdown state, which can only be cleared
by an OUTPut:PROTection:CLEar command or by
manually resetting the output.
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. This mode is equivalent to using
the Output On/Off button on the front panel.
Default mode. This mode is active at power up.
OFF
The instrument ignores the RI input.
Table 4-4: Factory Default Power on Settings
The RI output state is saved as part of an instrument setup using the REGISTERS menu. It can
be made part of the power on
needed. The default state is LIVE.
