At the display, the current measuring value is displayed. The
touch display enables sensor configuration.
By short-time application of a 24 V DC signal at the calibration
input, the current measuring value is reset to 0. This way, the
transmitter can be calibrated for known measuring media (reset to
zero). This can also be realised by means of the "Offset Val" menu
function.
2.2
Functions
Applies an offset to reset the current measuring value to 0.
This function corresponds to the calibration input via the external
contact.
Sets the measuring value to be displayed:
•
H
igh
R
esolution
U
nit (HRU)
•
Turbidity
Independent from display toggling, the analogue output always
returns a signal depending on the turbidity.
Sets the 4 mA point for the output current. The range can be
freely selected between 0…100
%.
Sets the 20 mA point for the output current. The range can be
freely selected between 0…100
%.
Applies damping at the turbidity value by continuous averaging.
Sets the switch-off point of the contactor. The range can be freely
selected between 0…100
%.
Sets the switch-on point of the contactor. The range can be freely
selected between 0…100
%.
Sets the switching function of the contactor. NC and NO contacts
can be selected.
Sets the switching function of the contactor. The range can be
freely selected between 0...200 seconds.
