If KTY, Pt500 or Pt1000 is selected, the channel Offset will appear, in which an
individual offset can be adjusted for each sensor.
Î
In order to select a sensor for the offset adjustment, select the corresponding
menu item by pressing button
➄
.
Î
To adjust the sensor offset, select the desired value by pressing buttons
❷
or
❹
, then confirm by pressing button
➄
.
Note
If a sensor is used as the temperature sensor of a function, the sensor
types Switch, Fern, BAS, Impulse and none will not be available for the
corresponding input.
ATTENTION!
Damage to the device!
Sensor inputs which have been set to the sensor type switch can
only be used for connecting potential-free switches.
Î
Make sure no voltage is applied!
If switch is selected, the inverted option will appear and can be used for inverting
the behaviour of the switch.
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, connect the sensor ground
common terminal block to PE (see page 7).
