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
offset appears, in which an individual offset can be
adjusted for each sensor.
Î
In order to select a sensor for the offset adjust-
ment, select the corresponding 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
Î
Confirm 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).
