Connecting the Encoder
Encoders are connected to the ALEC using a supplied cable assembly.
Two encoder cable assemblies are available as shown in the following
table.
The encoder cable assemblies shown in the preceding table are
electrically identical. The only difference is their length.
Connect the encoder to the ALEC encoder cable assembly as shown in
the following diagram.
Figure 2.4 Wiring diagram for connecting the Encoder to the ALEC
Plug the other end of the encoder cable assembly into the
Incremental Encoder Input connector on the front panel of the ALEC.
The encoder power supply in the ALEC provides 5 or 12 volts DC for
powering the encoder. Voltage selection is by DIP switch 1 on the
front panel. Push the switch all the way to the left for 12V encoders or

Order Number Length
4100-CAE15 15 feet (4.5 meters)
4100-CAE30 30 feet (9 meters)
IMPORTANT
Anchor the cable so that no more than 2 feet of cable is
left unsupported. The excessive weight of an unanchored
cable could pull the plug out of the connector.
