2-4. Mode Selector II Operating Procedure
2-4-1. Introduction
The Mode Selector II is a mechanism drive tool that assists main-
tenance work of the various mechanism decks. It has the follow-
ing 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 mechani-
cal 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 mecha-
nism deck is operating normally or has abnormality from a series
of movements of a mechanism deck. If an abnormal status transi-
tion is detected during operation, the "NG" indication appears and
the mechanism stops moving.
