1. Roller bearings in gear drives normally operate at 160 71 C 180 F 82 C Overheating in motors and gearboxes can be caused by increased bearing loads due to machine imbalance or misalignment Contamination of the roller bearings lubricant by solid particles water and other fluids can reduce the life of the bearings Improper lubrication generally causes overheating or excessive wear in the roller bearings These conditions can result from insufficient or excessive lubrication improper lubricants e g viscosity is the load bearing component of the lubricant Too thin then the bearings cannot properly carry the load and too thick then the amount of friction will generate heat Packing the space around the roller bearings with grease can also cause excessive heat Avoid the use high pressure grease guns since they may rupture the bearing seals Appendix B MODBUS registers of VTB sensor Register Name Description 40001 SYSTEM INFO Firmware ID and REVISION read only Control register to drive the most critical system commands 0 idle 1 reset 22222 update MODBUS STATUS register 40002 40003 40004 40009 40010 40011 SYSTEM CONTROL read write SYSTEM STATUS read only SYSTEM STATE 1 read only SYSTEM STATE2 read only MINUTES SINCE POWER ON read only HOURS SINCE POWER ON read only DAYS SINCE POWER ON read only ALARM RELAY1 STATE read2.
