are not being used.
Disable the Load Discon-
nected Detection function for

used.
The Load Disconnected Flag is
going ON for an output even
though the load is connected.
The load’s current consump-
tion is too low. (The minimum
output current is 3 mA.)
Disable the Load Discon-
nected Detection function.
(The function cannot detect
disconnection of this load.)
A disconnection was corrected
after being detected by the

reset. (The default setting is
manual reset.)
After correcting the discon-
nection, turn the I/O power
supply OFF and then ON
again.
