Usage of warning sheets in maintenance
Before performing maintenance, affix the included warning sheets (see below) to prominent positions in
the vicinity of the operating panel, for safety.
During the maintenance by two or more persons in particular, as well as using these warning sheets to
ensure safety, be sure to send signals.
This warning sheet uses a magnet.
Do not use it or store it near magnetic media or any other items
susceptible to magnetic influence.

The uninterrupted power connectors and the motor that does not
stop if an emergency stop switch is pressed
Even if an emergency stop switch is pressed, the motor for the vacuum pump does not stop. This is
because the motor prevents picked-up components from dropping.
The following power connectors are uninterrupted.
1. Power connector for the CPU box
2. Power connector for the tray
3. Power connector for the inspection truck
The other motors (see below) stop if an emergency stop switch is pressed.
1. X-axis/Y-axis motor
2. Head Z-axis/
θ
-axis motor
3. Conveyor motor
4. Width-adjustment motor
5. Support vertical-axis motor
