Miscellaneous

Overload Protective Circuit

This machine is equipped with an overload protective circuit. Normally, the driving 
motor rotates forward to feed screws to the escape continuously. However, if there is an 
overload at the driving section, the driving motor rotates backward for a certain amount 
of time and then returns to normal rotation.
When the cause for the overload is removed, during the reverse rotation, the driving 
motor returns to the normal rotation.
If the cause of the overload is not removed during the reverse rotation, the driving motor 
repeats the sequence of reverse rotation/normal rotation to shut off the power to the 
driving motor. NOTE: ASK DAN IF HE CAN HELP WITH THIS SECTION JUST FROM IF TO 
OVERLOAD. 
During this time, the escape action is not stopped. When the power to the driving motor 
shuts off, turn OFF the power switch and remove the cause of the overload. For example, 
when too many screws are loaded into the hopper, reduce the quantity of loaded screws 
to a proper level. If any screw is caught in the transport section, remove it.
After removing the cause of the overload, turn ON the power switch to operate the 
machine.
