Centerline (Vertical) Movement Overview

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.

Centerlines are saw blade movements on the Y Axis (vertical movements – up & down).

All Retro C component saws contain one of two versions depending on the generation of the saw.

• Version 1 is the Joyce Actuator which is an enclosure screw that moves up and down.
• Version 2 is a gearbox with #50-2 chain to move the centerline to the correct position.

Both versions have an encoder under a gray cover on the top of the machine. The encoders must be secure in order to keep calibration and at times either the set screw will get loose or the spring clips may break. They must be repaired if broken to avoid errors and loss of calibration.

Version 2

This centerline has 4 major components to it Motor, Gearbox, Encoder and Chain. The encoder is mounted on the opposite side as the chain on the end of the shaft under the cover shown below. The wiring for the motor enters directly next to it as shown below. The Gearbox is the gray unit in the picture below.

The Chain is on the outside under a gray cover that moves the unit up and down to position.

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.
