Outline

This unit is a mechanism drive tool which supplements the
maintenance of each mechanism deck. Its functions are described
below.

1. Manual test

A mode which drives the motor only while the switch is ON. It
enables the operator to control the motor as desired.

2. Step test

A mode which drives the motor until the current condition detected
by the sensor changes to another condition. It enables the movements
made by the motor in each operation to be controlled while being
checked.

3. Auto test

A mode that checks if the mechanism operates normally according
to the condition shift table recorded in the unit for each mechanism
deck. All the conditions of the decks are checked through a series
of operations.
An error message is displayed if incorrect shifts and conditions are
detected and operations are stopped.
