8. Overload Detection
⚫
The axial movement of the sensor plate is used to determine overload.
⚫
The plate moves with every trip revolution. Use a proximity switch that can sufficiently detect the sensor plate displacements as
shown in the table below.
⚫
If using a TGA sensor, read and follow the instructions provided in its manual.

9. Resetting
This auto-resetting type only requires restarting the motor, and other parts of the drive unit to reengage.
①
When the TGB trips from overload, stop the motor and remove the cause of overload.
②
Reset TGB and operate at 50 rpm or slower or by inching the motor. Never reset manually.
③
The clicking noises indicate that the drive balls have rolled back into their positions.
10. Maintenance
①
SHOCK GUARD
Apply a thin layer of grease to the drive balls and Thrust bearing, once a year or every 1000 trips.
