Electrical Installation
All connections to the Series 340N2 are made to screw termi-
nals on removable headers.
Power Supply Wiring
The Badger
® Series 340N2 requires 12-24 Volts AC or DC to
operate. The power connections are made to the oranGE
header. The connections are labeled beside the header.
Observe the polarity shown on the label.
If a Badger Meter plug in type power supply (Model A-1026
or A-503) is used, connect the black/white striped wire to the
terminal marked positive (+) and the black wire to the terminal
marked negative (-).
Note:
Included with every Series 340N2 is a Model 340N2IK kit
containing a screw, lockwasher and ground lead to connect
the Series 340N2 to earth ground. Connect the earth
ground lug of the Series 340N2 to a solid earth ground with
as short a wire as possible. This will help prevent electrical
interference from affecting the Series 340N2’s normal
operation.
Sensor Wiring
All flow sensor types connect to the four terminal header
labeled “Sensor Input”.
Series 200
Connect the red wire to Series 340N2 Sensor signal (+),
connect the flow sensor black wire to Series 340N2 Sensor
signal (-) and the bare wire to shield.
SdI Series (standard pulse output option)
Connect SDI number 3 sensor signal to the Series 340N2
transmitter sensor signal (+) and the SDI number 2 sensor
common terminal to Series 340N2 transmitter sensor signal
(-). Connect the shield terminal of the SDI sensor to the shield
terminal of the Series 340N2 transmitter.
other Sensors
The Sensor Input power out terminal supplies nominal 12VDC
excitation voltage for 3 wire sensors. Connect sensor signal +
and sensor signal - wires to transmitter terminals.
Note:
The green input LED toggles on and off as sensor pulses
are received. With no flow input the LED will remain in its
last state (either on or off).
