LED
4.4 - Power supply
• Nominal voltage: 3,2 ... 6V DC
• Average current consumption: < 50 µA. (depends on product configuration)
4.5 - Optional connecting AXONIC with Pulse-Box to integrator unit (optional power supply)
The Pulse-Box offers the following functions:
• Power supply of AXONIC independently of the integrator. • Pulse length increase of AXONIC’s pulses.
• Galvanic insulation of AXONIC from the integrator. • 2 wire pulse output
Before connecting, make sure that the pulse of AXONIC and integrator match!
Connection of AXONIC with Pulse-Box to an integrator according to mounting instructions: respect polarities!
Characteristics of pulse exit:
• Version: Open collector
• Polarity: non reversible (respect connecting diagram)
• Duration of impulse: 135 ±35 ms
• Maximum input voltage: 30 V DC
• Max. input current: 27 mA
• Voltage drop when switched on: ≤ 0.3 V at 0.1 mA, ≤ 2.0 V at 27 mA
• Resistance when switched off: ≥ 6 MΩ
• Maximum pulse frequency: 1Hz
• Maximum cable length: 10 m
5 - FUNCTION CONTROL OF AXONIC
The AXONIC flow sensor is equipped with a LED in order to perform a simple functional check. The signal sequence
depends on operation conditions and will be repeated any 10 as follow:
Information Number of flashes Signal/Period (Repetition)
Flow detected 1 20ms (LED ON) / 10s
Air in pipe / US Asic alarm 2 20/500ms (LED ON/OFF) / 10s
Low signal amplitude alarm 3 20/500ms (LED ON/OFF) / 10s
Max flow alarm 4 20/500ms (LED ON/OFF) / 10s
Back flow alarm 5 20/500ms (LED ON/OFF) / 10s
Product in test mode Permanent flashing 20/500ms (LED ON/OFF) / permanent
Product configuration un-locked
Flash sequence as above 1…5,
but inverted
500/20ms (LED ON/OFF) / 10s
Product configuration corrupt Permanent ON Permanent (LED ON)
Function control at the calculator:
A functional control and plausibility check shall be done by observing the indications of flow rate and volume index, see
calculators manual and operating instructions.
Putting into operation:
After successful functional test AXONIC is now ready for use and final technical inspection.
• Peak current consumption Imax: < 3 mA
