Selection Function
Off delay delay setting
function
To set off delay time to a desired output using the rotary switch on the front

Page 68 Off Delay Delay Setting
Function
Muting function
To temporarily disable the protection function of a safety device.
AND link
To activate the logic path of safety functions according to the input from an
FX5-SF-8DI4.
OR link
To bridge logic path A or B of safety functions according to the input from an
FX5-SF-8DI4.
Bypass
To bridge logic path A or B of safety functions according to the input from an
FX5-SF-8DI4, and forcibly turn ON the safety output for 60 seconds.
Restart interlock
To prevent a system from restarting until safety is verified and a reset signal
is input after safety outputs are turned OFF.
External device monitoring
(EDM)
To monitor if a contactor is OFF when the module is reset.

Monitoring (EDM)
Retriggering of the delayed
OSSDs
To reset a delay time to keep a machine operating when safety inputs are in
the safe state by the time off delay time elapses.

Delayed OSSDs
ENABLE input (XS0 terminal)
XS0 is a terminal to enable safety outputs. The terminal can be used to
cascade safety circuits.

Terminal)
Two-hand operation/jog mode
To control a safety system using a two-hand control device connected to an
FX5-SF-MU4T5.
Jog mode limits the duration time that keeps safety outputs Q2 and Q3 ON
for five seconds by the operation of a two-hand control device.

Mode
Diagnosis
Error history function
To store the history of errors occurred in a safety extension module to the
buffer memory.
Safety information monitoring
function
To store information including the I/Os, settings, and error codes of a safety
extension module to the buffer memory.
The safety information can be referenced by user programs and built-in
functions (such as Web server) of a CPU module or the monitoring screen
of GX Works3.
