Failsafe
P840 Output Fail-safe Mode
This parameter determines what happens to the output in the event of the
unit going into fail-safe mode. The
default
is to do the same as the
system
fail-safe
(
P808
), but this can be overridden to force the mA output to an
independent fail-safe mode as follows:
Option
Description
0 = Default
output will fail as per
P808
.
1 = Hold
output will retain its last known value.
2 = Low
output will fail to its
low
condition.
3 = High
output will fail to its
high
condition (5
VDC maximum).
4 = Very high
output will fail to its
highest
or
fault
condition of greater than 5 VDC.
