7.4 CLEARING JAMMED MOTOR
If one or more motors and helices become jammed,
the motor(s) will be displayed as a sublevel error
under “Motor Jammed”.
Energized vend motors can turn a helix with
considerable torque, creating a possible
entrapment hazard. Disconnect power to the
vendor or control board before freeing a jammed
helix or motor. Always restrain or block the helix
before freeing a jammed or caught product.
CAUTION: Use caution when freeing jammed
product (Refer to Section 2.2)!
Clear any jammed products from the indicated vend
columns.
To reset the error, first enter service mode, then
select Tray Setup (Refer to Section 6.8). Press “1”,
then “ * “, then “3”. The control will attempt to run the
jammed motors. If the motor had been taken out of
the motor matrix, it will be re-established in the matrix.
