1.1.2. Function selector (2)
The function selector allows choosing the function depending on its position. If there is no
function selected the display will show three dashes (- - -).
Function Description
Flow
Shows the actual flow in m³/h, l/s and Test for diagnosis (activated Test
function). This display matches with the feedback signal U.
The display starts flashing if the servomotor hits an end stop before
matching actual to reference flow.
An overflow (higher pressure as 250 Pa = 1.0 inWC) is indicated in the
display by a small circle.
Turning the value selector allows unit selection. The appropriate dot is
toggled as indicator. The units are converted.

Allows to set the direction of rotation (normal and inverse) and the input
signal range (0…10 V

Test
Opens the diagnose menu. All input signals on Y are neglected and the
controller only operates according to the selected override function. All
override functions are disabled after a time-out of 10 hours.
The display toggles after the selection of the function between the ac-
tual flow (8s showing time) and the function (2s showing time).
Selecting another function will disable the Test function and set it auto-
matically to
