connected Detection
function
DRT2-OD16SLH(-1)
DRT2-OD32SLH(-1)
DRT2-MD32SLH(-1)
Details
The Load Disconnected Flag is
going ON for outputs that are
not being used.
The Load Disconnected Flag is
going ON for an output even
though the load is connected.
A disconnection was corrected
after being detected by the
external load disconnected
detection function, but the Load
Disconnected Flag does not go
OFF.
Probable cause
The Load Disconnected
Detection function may not be
disabled for the outputs that
are not being used.
The load's current consump-
tion is too low. (The minimum
output current is 3 mA.)
The function is set for manual
reset. (The default setting is
manual reset.)
Section 9-2
Remedy

nected Detection function for

nected Detection function.

nection, turn the I/O power

again.
