16.2 Inputs
In this submenu, the type of the sensor connected can
be adjusted for each individual input. The following ty-
pes can be selected:
• Switch
• KTY
• Pt500
• RTA11M
• Pt1000
• None
If KTY, Pt500 or Pt1000 are selected, the channel
Offset appears, in which an individual offset can be
adjusted for each sensor.
Î In order to adjust the offset, select the corres-
ponding menu item by pressing button

CS sensor offset
If a CS10 irradiation sensor is to be connected, an
offset has to be carried out before the connection
is made.
To carry out the offset, proceed as follows:
Î Adjust the CS type in the Type channel
Î Select the Offset channel
Note:
If Grundfos Direct Sensors TM are used,
connect the sensor grounding common ter-
minal block with the protective grounding
conductor (see chap. 2.2).
Î Confirm the reset enquiry with Yes
Î Select back to return to the Inputs menu,
then connect the CS sensor
ATTENTION! System damage!
Selecting the wrong sensor type
will lead to unwanted controller
actions. In the worst case, system
damage can occur!
Î Make sure that the right
sensor type is selected
for each input!
