Description
1
L+
Supply voltage 18 V DC … 30 V DC
2
Digital output Q1
Functions:
1. Pulse
2. Empty pipe detection
3. Dosing output
4. Threshold monitoring
5. Negative flow
Digital output Q1
Can be freely set in the range of 0.1 to 3000 ml/pulse in
stages of 0.1 ml/pulse, npn or pnp
transistor,
max. load 18 ... 30 V / 100 mA.
Programmable output of 0 V or 24 V when
measuring tube is empty.
Programmable output of 0 V or 24 V when a preset
threshold is exceeded or not reached.
Programmable output of 0 V or 24 V during
negative flow.
3
GND
Supply ground: 0 V
4

4. Negative flow
Digital output Q2
Can be freely set in the range of 0.1 to 3000 ml/pulse in
stages of 0.1 ml/pulse, npn or pnp transistor,
max. load 18 ... 30 V / 100 mA.
Programmable output of 0 V or 24 V when
measuring tube is empty.
Programmable output of 0 V or 24 V when a preset
threshold is exceeded or not reached.
Programmable output of 0 V or 24 V during
negative flow.
5
Analog output QA
Functions:
1. Flow
2. Temperature
4 ... 20 mA; 0 ... 20 mA
For example: 0 l/min => 4 mA
36 l/min => 20 mA
Alarm => 3,5 mA
(dependent on set measuring area)

7
Digital input IN1
1. Dosing input
2. Offsett compensation
3. Reset counter
4. Creeping flow
Digital input IN1
Starts the dosage by a rising edge of 24V.
The Offset is set by a rising edge of 24V.
Reset of the counter by a rising edge of 24V.
Creeping suppression is deactivated as long as
there are 24V at the input..
