INSTALLATION

Qualified personnel must perform all wiring in accordance with prevailing codes
Fusing must be installed in line power, and should be of the slow-blow type Badger Meter recommends 1 amp for AC input

models and 5 amp for DC input models
Wiring should be routed to the actuator through one of the two 1/2 inch conduit openings Generally, one conduit contains

input power and earth ground wires The other conduit contains low level input and output signal wiring
All low level signal wiring should be a shielded type with the shield grounded at source common After installation, seal all

conduits to prevent water damage
Strip 0 22 inch (5 6 mm) of insulation from the wire and insert the bare end into the appropriate terminal location, using an

insertion tool or a small screwdriver as shown below

Maximum recommended wire size is 14 AWG, and minimum is 26 AWG

Wiring to TB1

Input power terminates at TB1 For AC models, terminal 1 is line, and terminal 2 is neutral The incoming power supply earth

ground should be securely connected to the green ground screw located inside the actuator base between the two conduit

entries For DC models, terminal 1 is positive (+), and terminal 2 is negative (–) Terminal strip tabs are pressed down to

insert wires

Wiring to TB2

LS1 and LS2 are factory-wired as end-of-travel limit switches

OTEE:

N

Because amplifier ZERO and SPAN setpoints are always active, LS1 and LS2 must be set within ZERO and SPAN of the

amplifier

Current command (4…12 mA, 12…20 mA, or 4…20 mA) wiring terminates on terminals 3 (–) and 4 (+) Voltage command

(0…5V DC or 1…10V DC) wiring terminates on terminals 5 (+) and 6 (–)

Wiring to TB3

If LS3 and LS4 are used as auxiliary position limit switches, connection is to terminals 1 through terminal 4 Maximum voltage is

40V DC and maximum current is 40 mA The 4…20 mA position feedback signal wires connect to terminals 9 (+) and 10 (–)
Increasing command signal will result in an increasing position feedback signal Operation of the transmitter requires

an external DC power supply in the range of 12…36V DC and a positive load connected in series with one lead from the

power supply
