2-5. Mode Selector II Operating Procedure

2-5-1. Introduction

The Mode Selector II is a mechanism drive tool that assists
maintenance work of the various mechanism decks. It has the
following functions.
1. Manual Test
In this mode, the motor of the mechanism deck is powered only
during the period while the switch is turned on manually. Using the
Manual Test, the operator can freely control the motor of the
mechanism deck.
2. Step Test
In this mode, the motor of the mechanism deck is kept turned on
until the mechanical status is changed from the present mechanical
status that is obtained from the sensor information. The Step Test is
used to confirm a series of movements of the mechanism deck.
3. Auto Test
The Mode Selector II stores the status transition table in its memory
as data indicating the respective modes of the mechanism deck.
The status transition table can be used to confirm whether a
mechanism deck is operating normally or has abnormality from a
series of movements of a mechanism deck. If an abnormal status
transition is detected during operation, the "NG" indication appears
and the mechanism stops moving.
