Power Supply Wiring
Below section describes the available power supply types for the D012-P. Which types are
available in your particular D012-P depends on the ordering code.
Battery equipped models switch their internal battery off when an external supply is active.
The following power supply options are available:
• Battery powered. see "Battery powered type PB" on page 10 for details.
• Externaly powered, see ""External Power Supply wiring" on page 10" for details.
Battery powered type PB
Type PB is internally battery powered and does not require any external wiring.
When power supply PX is available (see below) the internal battery is switched off. This extends
battery life and guarantees higher availability during power outages.
• A healthy battery has a life expectancy of several years, depending on its use and
configuration settings. For details see "Battery life" on page 27.
• When installing verify that the battery is in good working condition by running the power-up
sequence on page iv of this manual. If the battery needs to be replaced follow the battery
replacement instructions delivered with the new battery.
External Power Supply wiring
The D012-P can be equipped with a power supply, type PX or PD.
• For type PX or PD DC your D012-P must be equipped with a 6 pole connector.
Type PD can also power your flowmeter in the field, see "Power wiring type PD" on page 10 for
details.

Power wiring type PM
Type PM is a galvanically isolated highpower switching power supply, converting 115–230Vac
mains (50/60Hz) to power the D012-P,the backlight (option) and provides up to 24V sensor
supply to the field.
Backlight
For those applications where readability during day and night is an issue, a bi-color backlight is
available. The background color can be set to green or amber and the intensity can be adjusted
in the configuration menu, see 32 "Backlight" on page 24
Backlight requires a power supply of at least 16V and is internally powered by options PD, PM or
PX above 16V.
Warning
•HIGH VOLTAGE! Danger of electrical shock: remove power from the supply lines
before connecting.
Warning
• Never connect 24V AC and DC together on the same unit, this will damage the unit.

I/O wiring options
Flowrate Indicator / Totalizer Input Wiring Options Type P
Below flowmeter signal types can be connected to the D012-P.
The screen of the signal wire must be connected to the common ground if not earthed at the
sensor itself.
The maximum input frequency is approximately 10 kHz (depending on the type of signal). The
input signal type has to be selected with the correct SETUP-function (see "Signal" on page 25).
Explanation of symbol ‘cable shielding’
Low pass filter
A low-pass filter is an electronic filter that passes low-frequency signals and attenuates (reduces
the amplitude of) signals with frequencies higher than the cutoff frequency.
Sine-wave (Coil) Signal
The D012-P can be connected to flowmeters with a coil output signal.
Two sensitivity levels can be selected with setup menu 51 "Signal":
• COIL LO: sensitivity about 120mVp-p.
• COIL HI: default sensitivity about 20mVp-p.
(with type ZF COIL HI sensitivity is increased to 10mVp-p and with type ZG to 5mV p-p.)

Pulse-signal NPN / NPN-LP
The D012-P is suitable for use with flowmeters which have a NPN output signal.
For reliable pulse detection, the pulse amplitude has to go below 1.2V. Signal setting NPN-LP
employs a low-pass signal noise filter, which limits the maximum input frequency. See "Low pass
filter" on page 12.
Pulse-signal PNP / PNP-LP
The D012-P is suitable for use with flowmeters which have a PNP output signal.
3.0V is offered as a pull-up voltage which has to be switched by the PNP sensor. Optionally an
8.2/12/24V pull-up voltage can be wired, when powered with a power supply type PD/PM.
For a reliable pulse detection, the pulse amplitude has to go above 1.2V. Signal setting PNP-LP
employs a low-pass signal noise filter, which limits the maximum input frequency. See "Low pass
filter" on page 12.
For a signal detection level of 50% of the supply voltage: please refer to "Flowmeter Pickup
Signal Types Supported" on page 33
