Rockwell Automation 4100 ALEC AXIS LINK ENCODER CONVERTER - Manual (Page 40)

Publication 4100-5.3 - June 1999
32 Setup
The correct mode must be selected before applying power to the
ALEC and before connecting the encoder, otherwise an improper
voltage may be applied to the encoder, possibly causing damage.
Remember, the ALEC only reads the mode switch at power up or after
reset to determine the periodic update rate.

Select the proper Mode and DIP Switch settings before
applying power to the ALEC to avoid encoder damage.
IMPORTANT
Encoders in a given family not shown in the above table
are NOT compatible with the ALEC and should not be
used.
