Replace a Centerline 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 centerline encoder is the counter that tracks the position of the vertical movement.

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.

The centerline encoder is located either on the end of the shaft for the (older) Joyce actuator style or on the end of the shaft of the gearbox (newer style) behind a gray cover (shown below).

Remove the two screws holding the encoder in place and unplug the wire.

Loosen the set screw (set screw location is circled in red). And the encoder will slide off.

Remove the Encoder block.
Cut the new encoder to the length of the old encoder and wire it into the encoder block. Encoder Wiring Diagram

Remount encoder block and encoder on to the machine.

Secure the Set screw that holds the encoder.

Screw in the (2) 8-32 screws into the flanges on the encoder.

Mount the encoder block.

Add the encoder wire mount,

Test the encoder.

Re-Install all of the covers.

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.
