PRO-READ ENCODER REGISTER
Before removing the ProRead receptacle, ensure that the ProRead register is
programmed for three-wire mode.
• If a two-wire conductor cable is connected to a "potted" ProRead encoder
register, replace the register with a three-wire register.
Reprogramming a ProRead encoder from 2-wire to 3-wire
It may sometimes be necessary to reprogram a ProRead register encoder from 2-
wire to 3-wire mode. Accomplish this with a Neptune ProRead field programmer.
A basic overview of the steps is as follows:
1 Connect to the remote receptacle with the field programmer.
2 Interrogate the encoder register to determine its operating mode (2 or 3-wire).
3 Reconfigure the encoder register to make it operate in 3-wire model.
4 Verify that the reconfiguration was successful by looking at the Field
Programmer screen. The OM field should be 3W (see below).
Table 2.1
If the register has screw terminals, proceed to "Connecting a Neptune Auto or
Sensus Encoder Register with Screw Terminals" on page 2-3.
If the register has potted leads, proceed to "Connecting a Badger, Neptune Auto or
Sensus Encoder Register with Potted Leads" on page 2-6.
