SENSOR SUPPLY
For type PB/PC; PX; AP:
There is no real sensor supply out available. Only a limited power supply
is available. This power supply MAY NOT be used to supply the flowmeters electronics, converters
etc. as it will not provide adequate sustained power ! All energy used by the flowmeters pick-up will
directly influence the battery life-time. It is strongly advised to use a "zero power" pickup such as a
coil or reed-switch when operating without external power. It is possible to use some low power NPN
or PNP output signals, but the battery life time will be significantly reduced (consult your distributor).
The sensor supply is fixed: 1.2V DC or 3V DC (set by the firmware).
For type PD; PF; PM:
It is possible to supply the sensor with different voltages. You can set the
voltage with the switches. Internal power is only applicable for low power sensors (Coil, Reed).
External power is only available when the main external power supply is connected.
The sensor supply voltage is selectable: 1.2; 3; 8.2; 12 or 24V DC.
