23.3.6 Adjusting the output values
Similar to the input of set values, when monitoring an
actual value by means of an external device via the I10
plug, there can be a difference between the actual tem-
perature shown on the display of the circulator and the
actual value of the external device.
This difference depends on tolerances in the
I10 board
and the external
device.
By setting an offset value, the value
(i.e. a
voltage or a
current, respectively) on the external device can be
adjusted to the temperature shown on the display of the
circulator.
E.9.: current output with 0...20 mA = O...lOO°C (chan-
nel 5) is selected. On the external device 8.0 V is set to
give a set temperature of 80°C. On the display of the
circulator the actual temperature
80.00°C is shown.
(The
actual temperature is always in the centre
of the
display.)
[JJ
external device
Due to some tolerance, the actual temperature on
external device is not 80.00°C but 81 .40°C.
1 80.00 "C 1
Off. O..PO mA (011 00°C)
This difference can be adjusted with an offset of
-1 .40°C.
To set the
offset get back to the
OUTPUT menu with the
MENU key and there select OFFSET.
In the
OFFSET menu you can set the offset value (i.e.
the difference between the two temperatures) with the
arrow
keys c- and +.
After this, the value on the external device and the set
temperature on the display
of the circulator are
adjusted.
Confirm with
ENTER to save the offset value.
On the display the voltage or current range of the
selected mode is shown (e.g. 0...20
mA, 0/10O0C). For
each channel an offset value can be saved.
