Before installing an L900 MIU, the encoder register must be
correctly wired and/or programmed to work with the L900 MIU.
E-CODER registers do not require programming.
When a ProRead encoder register is used, the non-
AutoDetect ProRead register must be programmed for three-
wire mode.
If connecting the L900 MIU 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 ProRead programmer and its
RF/L900 MIU 6, 8, or 10 ID TDI format. This can be
accomplished through the ProRead receptacle before it is
removed.
Installation of a Register (Non Pre-Wired or Potted Only)
Before wiring the pit encoder register, consider the following.
1. Make sure the cable is long enough. When the installation is
complete, the pit lid can be removed easily without straining
the cable.
2. Use only 22 AWG cable to make the connection from the
encoder register to the L900 MIU.
3. Remove the terminal screw from the encoder register.
4. Strip ¾-inch insulation from the cable jacket, leaving only the
three insulated wires.
5.
Take precautions not to nick or cut the insulation on the three
wires, strip off ½-inch of insulation from each of the three
wires.
