Select the temperature range with the arrow keys and
cnoose
4...20mA or 0...20mA in the
lower line I-INPUT.
Press the menu key to get back to the
INPUT
menu.
Here with START you can activate the selected values
to start the input via the
I/O port.
From now on the circu-
lator will receive its set values via the pre-set current.

you
try to start the programmer (only

while
the
I10 plug is active.
To start the programmer first stop the operation of
the
I10
plug
with

in
the
INPUT
or
OUTPUT
menu.
23.3.3
Adjusting the input values
If you give a set value by means of an external device
via the
I/O plug,
there can be a difference between the
set temperature shown on the display of the circulator
and the set value on the external device.
This difference depends on tolerances in the 110 board
and the external device.
By setting an offset value, the value
(i.e. a
voltage or
a
current, respectively) shown on the external device can
be adjusted to the temperature shown on the display of
the circulator.
E.g.: voltage input and the normal resolution mode
(0

is selected. On the
external device 8.0
V
is set to give
a
set temperature
of 80°C.
Due to some tolerance, the set temperature on the dis-
play of the circulator is not 80.00°C but
81
.40°C. (The
set temperature is always in the upper right corner of
the display.)
This difference can be adjusted with an offset of
-1
.40°C.
To set the offset get back to the NWT menu with the
MENU
key
and
there select
OFFSET.
