Flowmeter Supply Voltage
Selection (P+, P-)
All meters, including models equipped with the
12-24 VDC power option, are shipped from the
factory configured to provide 24 VDC power for
the transmitter or sensor.
If the flowmeter requires 5 or 10 VDC excitation,
the internal jumper J4 must be configured
accordingly.
To access the voltage selection jumper:
1. Remove all the connectors.
2. Unscrew the back cover.
3. Slide the back cover about 1 inch.
4. Configure the J4 jumper, located behind
the input signal connector, for the desired
excitation voltage as shown.

Connections
All connections are made to removable screw
terminal connectors located at the rear of the meter.
•
Use copper wire with 60°C or 60/75°C insulation
for all line voltage connections. Observe all safety
regulations. Electrical wiring should be performed
in accordance with all applicable national, state,
and local codes to prevent damage to the meter
and ensure personnel safety.

•
Use proper grounding procedures/codes.
•
If the instrument is installed in a high voltage
environment and a fault or installation error
occurs, high voltage may be present on any lead
or terminal.
•
Follow all fusing and wiring precautions
requirements for the instrument integrated to the
PD8 Series model number being connected.
To access the connectors, remove the enclosure
cover and unscrew the two captive screws that fasten
the electronics module. Signal connections are made
to de-pluggable connectors on the back of the
electronics module.
Some connectors may be provided already
connected. These connections are required for proper
operation of the ProtEX-MAX and should not be
removed unless instructed to by this manual.
Wires marked as being used for testing purposes
should be removed.
Grounding connections are made to the two ground
screws provided on the base
