Visual Indicators and Controls
Green LEDs indicate current flow
Orange LED indicates setpoint, output closed
Red LED indicates setpoint outpoint open
LED 9 flashing indicates current flow is above
the taught flow range
LED 0 flashing indicates current flow is much below
the taught flow range
Pushbuttons for automatic / manual setting
A short circuit is indicated when the display alternately
changes between all red LEDs and the current flow indication.
If no LEDs are lit, check supply voltage (must be >19 V).

Set-up and scaling the display
The sensor is factory preset to monitor the range 5…100 cm /
sec of water and setpoint position of LED 7. If the adjustments
are required, follow these instructions.
High flow adjustment
This adjustment calibrates the sensor so that all LEDs are lit
when the maximum flow velocity is reached.
Allow the maximum flow velocity to circulate through the
system and keep it constant.
1
Press the pushbutton and hold. LED 9 lights,
after 5 seconds it flashes.
2
Release the pushbutton.
3
Setpoint adjustment
If a faster response time is desired (low setpoint = fast
response with rising flow, high setpoint = fast response time
with falling flow), adjust the setpoint as shown.
Briefly press either pushbutton or and release.
The setpoint LED flashes.
1
Press the pushbutton or as often as required. The
setpoint shifts by one LED position in the direction shown
by the pushbutton.
2
Output configuration
Factory default of the switching output is normally open (out-
put turns on when flow is above setpoint). The output can be
changed to normally closed as follows.
Press the pushbutton and hold. LED 0 lights, after 5
seconds it flashes.
1
Continue to hold the pushbutton, after 10 seconds the
current output setting is displayed (LEDs 5…9 orange =
normally open output).
2
Continue to hold the pushbutton, after 15 seconds LEDs
0…4 flash orange. Release the pushbutton. The output
has been changed to normally closed.
3
Return all settings to factory default
Press the pushbutton and hold. LED 9 lights, after 5
seconds it flashes.
1
Continue to hold the pushbutton, after 15 seconds LEDs
0…9 flash orange. Release the pushbutton. All settings
have been returned to factory default.
2
Low flow adjustment
If the sensor is used in media other than water, a low flow
adjustment should be performed. This adjustment must only
be carried out
after a high flow adjustment.
Allow the minimum flow velocity to circulate through
the system (or ensure no flow if that is the minimum
condition) and keep it constant.
1
Press the pushbutton and hold. LED 0 lights,
after 5 seconds it flashes.
2
Release the pushbutton.
