Replace the Carriage Encoder

Before You Begin

Safety: Stop the machine, follow the site lockout/tagout procedure, verify that hazardous energy is controlled, and release or secure stored mechanical and pneumatic energy before opening a panel, removing a guard, or adjusting components. Electrical work must be performed by a qualified technician.

The Carriage encoder is located under a gray cover (see photo below) under the carriage on the lumber feed side of the saw.

If you think the carriage encoder is bad and needs to be replaced follow these steps to replace it.

Warning: Before entering the saw make sure you have engaged the emergency stop with the key and take it with you as well. Always lock out, tag out the machine during maintenance in accordance with all local and/or company policies.

• Step 1: Remove the two bolts that hold the gray cover in place (they are accessible from the top)

• Step 2: You will need to cut the zip tie and remove the two screws that hold encoder in place.

• Step 3: Loosen the set screw. NOTE: the set screw might be in a place that you can’t see easily due to its rotation around the shaft/the position of the carriage.

Slide the encoder off and replace with a new encoder. Repeat steps 1-3 in reverse order

ADDITIONAL TIP:

Now is a good time to verify that the encoder’s gear is tight up against the gear rack. If the is any slop in the gears (see photo, position 1) then you will need to tighten the gear up. To do so loosen the lock nut and tighten top nut (see number 2).

Now, let’s connect the encoder wire to the wiring block situated on the opposite side of the Carriage’s support tube. You’ll find it positioned above the carriage brake, similar to the reference image provided.

The wiring should be wired either into this block or added with the screws if replacing the block fully. Encoder Wiring Diagram

Confirm the Result

After restoring the machine through the approved startup procedure, confirm that the position or count changes in the correct direction, returns consistently, and reaches the commanded value without an encoder, calibration, or overrun warning.

If the issue remains, record the exact on-screen message, affected component, indicator-light state, and the last change made. Provide those details to Enventek Technical Support; do not repeatedly recalibrate or replace parts without identifying the cause.
