5 How to Remove the Encoder

Hold the top of the Pull out the encoder

encoder firmly as shown

IMPORTANT Do not remove the encoder from the

bottom as it might damage the
encoder and the locking mechanism
on the control module.

(1) When using 12V Encoder power, 24V I/O power, maximum output current at I/O Terminal 11 is 50 mA.
(2) If Encoder requires 24V power, it must be supplied by an external power source.
