Analog Input 1
(Current Input)
Reference Value
(Set Flow or
Speed)
4..20 mA = 0..100% of full scale (flow control)
4..20 mA = 0..10000 rpm (speed control)
Speed limit = 9000 rpm, Cutt-off speed = 0 rpm
450 Ohm shunt input, no galvanic isolation.
The designation of the analog inputs can be changed
with Levitronix

Analog Input 2
(Voltage Input)
Configurable as
setpoint input
0..10 V
Analog voltage input: 0 – 10V
(7.9 kOhm, no galvanic isolation).
Note: Max. input voltage of 11 V shall not be
exceeded.

Digital Input 1
Enable
(Reset)
5-24 V  active
0 V  not active
Galvanic separation with optocoupler and
2.2 k input resistance.
The “Enable” signal switches the flow control system
on and off. Resets pump from error state with 300-
700ms pulse.
Din2

Digital Input 2
Zero Adjust
Edge triggered:
0V
5-24V
 Starts zero adjustment
Galvanic separation with optocoupler and
2.2 k input resistance.
Triggers a Zero Adjust of the flow sensor. Duration of
Zero Adjust process is about 5 seconds.

(Voltage Output)
Actual Flow
Value
0..10 V = 0..100% of full scale flow
Direct connection, no protection. Galvanic isolation on
user side is required. GND is reference.
The configuration of the analog output can be changed with
Levitronix

Service Software.
Dout1
brown
Digital Output 1
Status Pump
Closed circuit  active, pump running
Open circuit  not active, system off or error
Open drain, max. 24V, 100mA
This signal indicates the state of the flow control
system. If not active, pump is either in “Off” or in
“Error” state.
The configuration of the digital outputs can be
changed with Levitronix

Flow Sensor
Closed circuit  active, measurement o.k.
Open circuit  not active, measure. error
Slow blinking (2 Hz)  Zero Adjust error
Fast blinking (10 Hz)  Zero Ad. in progress
