6.8.5.8 REMOTE INHIBIT SETUP Screen
The REMOTE INHIBIT SETUP screen allows configuring the remote output control input for
various modes of operation. Once set, this setting is retained in non-volatile memory so the
selection persists between input power cycles.
There are three modes of operation for this input: remote inhibit and remote enable.
1. Disable mode: In his mode, the Remote Inhibit inputs are not active so this function
is turned off. No short between the RI pins is required to enable the output in this
mode.
2. Remote Inhibit mode: The two pins have to be shorted for the output to be enabled
from the front panel or remote command. This is a necessary but not a sufficient
condition to enable the output. If the output is enabled and the remote inhibit
connection is open, a fault is generated. This mode is recommended for interlock
safety applications such safety cages and test fixture interlocks.
3. Remote Enable mode: The output can be enabled by shorting these two pins,
regardless of the output enable command/button. It is a sufficient condition to
enable the output.
RS232 Interface and Remote Inhibit Function
On AFX Series models with firmware revision numbers lower than 2.0.13, there is a conflict
between the RS232 interface and the Remote Inhibit function. Both cannot be used at the
same time. To enable the Remote Inhibit input control line, the RS232 interface must be
disabled. This can be done using the browser interface over LAN or USB or from the front
panel. If the Remote Inhibit function is needed, use the USB interface instead of RS232.
To disable RS232 from Web browser, select
SYSTEM Menu -> INTERFACE SETUP and move
the SERIAL CONFIGURATION ENABLE position
to OFF.
To disable RS232 form the front panel, press
the CONFIGURATION key to the left of the LCD, select Interfaces, then select RS232
Interface and set the Status field to Disabled. Refer to section 6.8.5.4 on page 173.
