Reverse operating mode with set-point and differential change-over
from digital input [PRO=8]
• When in this mode both outputs operate in
reverse
, with set-point 1 /differential 1 or
set-point 2/differential 2, depending on the status of the digital input. More precisely,
with set-point 1/differential 1 if the digital input is open and set-point 2/differential 2
if it is closed.
Operating functions are the same as in mode 1. Therefore both set-points
[ST1]
and
[ST2]
and both differentials
[DF1]
and
[DF2]
must be confi gured.
Operating mode with outputs 1 and 2 respectively in reverse with
set-point 1 and diff.1 and direct with set-point 2 and diff. 2 [PRO=9]
• When in this mode output 1 operates in
reverse
and output 2 in
direct
.
It is necessary to confi gure set-points 1
[ST1]
and differential 1
[DF1]
for output 1,
and set-point 2
[ST2]
and differential 2
[DF2]
for output 2.
Operating functions are the same as in modes 0 and 1.
If only one output is present it will operate in reverse.
Alarm operating mode [PRO=10]
• When in this mode output 1 operates in
reverse
(with dead band) whilst output 2 is
reserved for the alarm.. It is necessary to confi gure set-point 1
[ST1]
, differential 1
