Verifying/Preparing the Encoder Register
This Wall MIU1 is designed for use with Schlumberger ProRead Encoder Rev. E, D and C.
Before installing an MIU, the encoder register must be correctly wired and/or programmed to
work with the MIU.
If a three-conductor cable is not connected to the encoder register, it will have to be
connected and run to the outside of the building. Refer to Steps 1 - 9 in this procedure for
that information.
If a three-conductor cable is already connected to the encoder register and available on the
outside of the building, the wire color/terminal screw connections on the encoder register will
have to be verified. Refer to Step 4 in this procedure for that information.
If a three-conductor cable already connects a Pro-Read
¨ encoder register to a wall-mounted
receptacle, the Pro-Read
¨ must be programmed for three-wire mode. Refer to Step 4 in this
procedure for that information.
If a three-conductor cable already connects a Pro-Read
¨ encoder register to a wall-mounted
receptacle, the cable may have to be extended to a location that is appropriate for mounting
the MIU. Refer to the section ÒSplicing a Three-Conductor Cable.Ó
1 Remove the terminal screw cover from the encoder register.
2 Strip off 3/4" from the jacket of the three-conductor cable.
3 Strip off 1/2" of insulation from each of the three wires.
4 Connect one wire to each terminal screw as described in Table 2.4 and shown
in Figures 2.4 and 2.5.

Note: If the MIU will be connected to a Pro-Read ¨ encoder register, the Pro-Read ¨ must be
programmed for three-wire mode using a Pro-Read
¨ programmer and its ten-digit TDI
format. Do this through the Pro-Read
¨ receptacle before removing the receptacle. For more
information about Pro-Read
¨ programmers, contact your Schlumberger sales representative.
