What causes fault code CONV-TEMP1 (Conveyor Bearing Temperature Alarm)?

Bearing lubrication insufficient — grease dried out or auto-luber empty. Bearing wear — internal clearance lost, metal-to-metal contact. Bearing overloaded — conveyor loaded beyond design capacity. Misalignment between motor and gearbox or gearbox and conveyor shaft — induces axial load on bearings. Wrong grease type used — incompatible greases cause breakdown

How do I fix fault code CONV-TEMP1?

Check bearing temperature with IR gun — compare to opposite side bearing for baseline. Grease the bearing with correct type and amount — do NOT over-grease, follow manufacturer schedule. Listen for bearing noise — rumbling, clicking, or high-pitched whine indicates failure modes. Check shaft alignment with straightedge or laser alignment tool — correct if needed. If bearing temp continues to rise after greasing, plan for bearing replacement at next maintenance window. When replacing bearing, inspect shaft for wear — a worn shaft will destroy the new bearing quickly

Conveyor Bearing Temperature Alarm

CONV-TEMP1

Bearing temperature monitoring system detected excessive temperature on a conveyor bearing. Temperature exceeded alarm threshold, indicating bearing wear or lubrication failure.

Probable Causes (ranked)

Bearing lubrication insufficient — grease dried out or auto-luber empty
Bearing wear — internal clearance lost, metal-to-metal contact
Bearing overloaded — conveyor loaded beyond design capacity
Misalignment between motor and gearbox or gearbox and conveyor shaft — induces axial load on bearings
Wrong grease type used — incompatible greases cause breakdown

Fix Steps

1 Check bearing temperature with IR gun — compare to opposite side bearing for baseline
2 Grease the bearing with correct type and amount — do NOT over-grease, follow manufacturer schedule
3 Listen for bearing noise — rumbling, clicking, or high-pitched whine indicates failure modes
4 Check shaft alignment with straightedge or laser alignment tool — correct if needed
5 If bearing temp continues to rise after greasing, plan for bearing replacement at next maintenance window
6 When replacing bearing, inspect shaft for wear — a worn shaft will destroy the new bearing quickly

Field Trick

Over-greasing bearings kills more bearings than under-greasing. When you pump grease into a sealed bearing, the excess has nowhere to go — it builds pressure, pushes past the seal, and overheats the bearing. Follow the OEM schedule: usually 2-3 pumps of the grease gun, NOT a full cartridge.
