This session describes the safety switches and module protection sen-
sors.
4.1 Safety Switches and Sensors
The safety switches and sensors work to stop the dangerous moving
mechanisms of the machine whenever an error is detected in the ma-
chine.
••
••
• The safety switches and sensors are set active on the machine side
(hardware), not by any software.
4.1.1 [EMERGENCY STOP] Switches
The multi-layer tray feeder is not provided with any [EMERGENCY STOP]
switches.
The [EMERGENCY STOP] switches of the main machine are com-
monly used for this feeder.
Press one of the [EMERGENCY STOP] switches to immediately stop
the machine in an emergency.
The power is turned off and the machine stops immediately.

layer tray feeder is shut off in 1 second after
the [EMERGENCY STOP] button is pressed.
• 24 V load power in the solenoid valve system ex-
cluding the solenoid valves for component picks and
the control power sources such as those for the

• When the LED of the [READY] button is ON, the safety
door cannot be opened because it is locked by the
electromagnetic lock switch.
• When the safety door has opened due to the break-
down of the electromagnetic lock switch, etc., with
the machine in operation, the power to the elevator
shaft is shut off.
