Maintenance Guide

The CMIU also operates with competitor registers using Sensus which include:
l Sensus ECRIII
l ICE
l iPerl
l OMNI, and electronic registers
l Hersey/Mueller Translator
l Badger ADE
l HR-E

Before installing a CMIU, the encoder register must be correctly wired and programmed to
work with the CMIU. E-CODER registers do not require programming.
When using a ProRead encoder register, the non-AutoDetect ProRead register must be
programmed for three-wire mode.
If connecting the CMIU to a new ProRead encoder register, or if a three-conductor cable is
already connected to a ProRead encoder register, ensure that the ProRead register is
programmed for three-wire mode using the field programmer, and the format is set to
(NTG) RF MIU Transport Driver Interface format (TDI). You can accomplish this through the
ProRead receptacle before removing the receptacle.
Installing a Register (Non Pre-Wired or Potted Only)
Consider the following:
1. Make sure the cable is long enough before wiring the pit encoder register.
2. Use only 22 American Wire Gauge (AWG) cable to make the connection from the
encoder register to the CMIU.
3. Remove the terminal screw from the encoder register.
4. Strip off 3/4 inch of the jacket from the cable, leaving only the three insulated wires.
5. Take precautions not to nick or cut the insulation on the three wires.
