3-1. OUTLINE
This unit is a mechanism drive tool which supplements the main-
tenance of each mechanism deck. Its functions are described be-
low.
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 de-
tected by the sensor changes to another condition. It enables the
movements made by the motor in each operation to be controlled
while being detected.
3. Auto test
A mode that checks if the mechanism operates normally accord-
ing to the condition shift table recorded in the unit for each mecha-
nism deck. All the conditions of the decks are checked through a
series of operations.
An error message is displayed and operations are stopped if incor-
rect shifts and conditions are detected.
