Description

Corrective measures
1
16x0313 Failure in the
input circuit
F-DI 4/F-DQ 2
digital inputs
Internal fault at the
read circuit/test circuit
•
The module digital
inputs detect a
failure during bit
pattern testing of
inputs
•
EMI or module
hardware fault
•
If intermittent, it is
probably due to in-
terference; elimi-
nate the
interference
•
If persistent, or
repeats after ef-
forts to eliminate
interference, re-
place the fail-safe
module
16x031C Input shorted to P F-DI 4/F-DQ 2
digital inputs
Input shorted to P
failure
•
External wiring or
sensor shorts input
signal to L+
•
Input configured
for internal sensor
supply with short-
circuit detection
enabled, but wired
to external L+
•
Input defective
•
Check/correct ex-
ternal short-circuit
•
Make wiring and
configuration agree
•
Replace the fail-
safe module
16x031E
Read back failure F-DI 4/F-DQ 2
digital outputs
The module has de-
tected a channel prob-
lem where the
expected terminal
voltage(s) are not
reached
•
"Maximum read-
back time" or "Max-
imum readback
time switch on
test" configured
value is too small
•
Output switch
failure
•
Increase readback
time
•
Replace the fail-
safe module if out-
put does not re-
spond
16x0320 Overload
F-DI 4/F-DQ 2
digital outputs
Overload condition at
the output driver that
leads to passivation of
the channel
Overload at output
Eliminate overload
16x0321 Supply or load
voltage too high
Module
Supply voltage (1L+) or
load voltage (2L+)
maximum exceeded
Supply or load voltage
is set too high
Adjust supply or load
voltage
16x0322 Supply or load
voltage too low
Module
Supply voltage (1L+) or
load voltage (2L+)
minimum exceeded
Supply or load voltage
is set too low
Adjust supply or load
voltage
1
Once the fault is eliminated, reintegrate the fail-safe module (return to normal state) from passivation into the safety
program.
