Upgrading From ALEC Series C to Series D

The ALEC Series D has undergone some changes that affect the

mounting, wiring, and configuring of the ALEC when upgrading from

an ALEC series C to an ALEC series D.

Summary of Changes

Physical Dimensions

The length and width of the box have seen no appreciable difference

in size. The depth of the box has the greatest significance. The ALEC

series C has a depth of 4.5inches (114 mm) and the ALEC series D has

a depth of 5.125 inches (30.175 mm). However, the new design of the

mounting tabs decreases the difference to .25 inches (6.35 mm).

This should pose no problems for wiring the ALEC series D using

existing cabling.

Mode Rotary Switch

The Mode rotary switch has changed from a 10 position switch to a 16

position switch. The positions 0-7 are still used for setting the

frequency of the encoder position update. However the values are

not the same as they were in the ALEC series C. The following table

contains the Series C and the Series D frequency values.
