Power Supply - ITRON Axonic DN65 qp25 Manuel D'utilisation

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.
• Galvanic insulation of AXONIC from the integrator.
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:
• Polarity:
• Duration of impulse:
• Maximum input voltage:
• Max. input current:
• Voltage drop when switched on:
• Resistance when switched off:
• Maximum pulse frequency:
• Maximum cable length:
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
Flow detected
Air in pipe / US Asic alarm
Low signal amplitude alarm
Max flow alarm
Back flow alarm
Product in test mode
Product configuration un-locked
Product configuration corrupt
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.
