Angle Chains – Proper Chain Tension

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 angle chain need to be periodically checked to maintain proper chain tension. Proper chain tension will allow it move slightly from side to side but not so much that it becomes floppy or is able to move significant amounts, conversely you don’t want it so tight that it causes the angle motor to stall.

A properly tightened chain will act like this.

To tighten the chain you will need a 1/2″ open ended wrench and a #6 allen wrench. Use the 1/2″ wrench to loosen the (2) jam nuts shown below.

To lighten or loosen the chain you will need to use the allen wrench to tighten or loosen the (2) allen screws until you have achieved the proper tension.

After you have re-tensioned the chain, use the 1/2″ wrench to tighten the jam nuts back down.

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.
