16.2 Inputs
In this submenu, the type of the sensor connected
can be adjusted for each individual input. The fol-
lowing types can be selected:
• Switch
• KTY
• Pt500
• RTA11-M
• Pt1000
• None
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 sen-
sor type is selected!
If KTY, Pt500 or Pt1000 are selected, the channel
Oset appears, in which an individual oset can be
adjusted for each sensor.
Î In order to select a sensor for the oset adjust-
ment, select the corresponding menu item by
pressing button

CS sensor oset
If a CS10 irradiation sensor is to be connected, an
oset has to be carried out before the connection is
made.
To carry out the oset, proceed as follows:
Î Adjust the CS type in the Type channel
Î Select the Oset channel
Î Conrm the reset enquiry with Yes
Î Select back to return to the Inputs menu, then
connect the CS sensor
Note:
When Grundfos Direct Sensors
TM
are used, the
sensor ground common terminal block must
be connected to PE (see chap. 2.2).
