4.1.2 [Closed Safety Door Detection] Switches
When a safety door is opened with the [OPERATION] switch set to "RUN",
the corresponding [Closed Safety Door Detection] switch is activated,
causing an error and the load power is shut off.
When the [OPERATION] switch is set to "SETUP", only the power to
the motors for the X/Y beam and the heads is shut off.
The [Closed Safety Door Detection] switches are provided inside the
right edge of each safety door as follows.

When either the front or the rear safety door is opened,
the following takes place.
• The load power is shut off.
• Power to the motors excluding those for the vacuum
pump and the cooling fan is shut off.
Note: Power to the motors for the beam X/Y axis,
the traverse shaft and the elevator shaft of
the tray feeder is shut off in 1 second after
the [EMERGENCY STOP] switch 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 sensors is shut off.
Note: The load power for the safety doors, the so-
lenoids for electromagnetic locks, and the
solenoid valve for tape feed is shut off in 1
second after the [EMERGENCY STOP]
switch is pressed.

These switches are used to prevent any access to the spaces between
the feeders (the places where no feeders are installed) and any opera-
tor from taking out any installed feeder.

4.1.4 Maintenance Opening Detection Sensors
Whenever a foreign object (hand, fingers, etc.) is detected between the
safety door and a feeder during operation, these sensors are provided
to stop the X/Y beam for safety purposes.

When one of these sensors is turned OFF (light emit-
ted and received), the following measures are taken.
• The excitations of the beam X/Y axis and the nozzle
U/D axis are shut off.
(At the same time, the nozzle U/D axis is braked.)
