Error Handling and Error Resetting
Note
If a discrepancy error occurs in one of the pairs when set to Dual Channel
Equivalent (2 pairs) or Dual Channel Complementary (2 pairs), to reset the
error make input pairs 1 and 2 both inactive and then active.

Remove the cause of
the error and then
make the inputs in
active and then active
again (See note.), or
change the NE1A-
series Controller's
operating mode to
IDLE Mode and then
back to RUN Mode.
2. Function Test Re-
quired
If Function Test
Required is active:
Remove the cause of
the error and then
make the inputs
active, inactive, and
then active again
(i.e., perform the
safety gate test).
If Function Test
Required is inactive:
Remove the cause of
the error and then
make the inputs in
active and then active
again.
