Power Supply Wiring
Below section describes the available power supply types for the D077-A. Which types are
available in your particular D077-A 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 11 for details.
• Input loop powered, see "Loop Powered Flowmeter Input Wiring Option Type A-PL" on page 14
for details.
• Externaly powered, see ""External Power supply wiring" on page 11" 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 35.
• 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 D077-A can be equipped with several external power supplies, type PX, PM or PD (AC/DC).
• For type PX or PD dc your D077-A must be equipped with a 6-pole connector.
Type PD can also power your sensor in the field, see "Power supply" on page 5 for details.
• For type PD ac or PM your D077-A must be equipped with an additional 3-pole connector.
