12.6 Handling the Feeder Position Indicator (FPI)
The FPI is located at the front of the number label (indicating the feeder mounting
position) for the feeder bank, and equipped with LEDs which correspond to the
number of each number label. These LEDs indicate the feeder mounting position or
component supply condition by lighting or flashing as follows:
Table 12.6.1
Machine condition LED status Function
Flashing Indicates the hole (number) into which the
positioning pin is inserted to position the feeder
specified with the production program
Preparation
Lighting Indicates the range of the feeder bank which the
mounted feeder occupies.
Board production Flashing If the number of the components remaining at a
feeder gets less than the warning level which is
specified as the number of components in the
production program ( this value is set to notify an
operator that the number of the remaining
components is insufficient), the LED
corresponding to the position at which the feeder
is mounted flashes to indicate that the number of
the remaining components is not enough at the
feeder.
Components run-out Lighting If the number of the components remaining at a
feeder which is obtained based on the initial value
specified as the number of components in the
production program reaches "0" during production,
the LED corresponding to the position at which the
feeder is mounted lights to indicate that
components run out at the feeder.
Manually controlled When the feeder
knock pin is set to
ON: Lighting
OFF: Not light
If you use the feeder knock pin control function
which is provided on the Manual control menu to
feed tape or perform the direct knock action, the
LED located at each controlled feeder positioning
pin flashes according to the feeder knock pin
action to indicate which knock pin is controlled.
Note: Unless you enter the number of components to be fed to the feeder or
equivalent correctly at the menu item [Component no. setup] displayed on the
[Change] menu which is invoked from the menu command [Pwb Production],
the number of the remaining components is not displayed correctly and the
indication for component run-out is not displayed properly.

12.7 Handling Bad Mark Sensor
1) Color and size of a bad mark
a) A bad mark on a PC board to which green resist is applied shall be a glossy
white mark of 2.5 mm in diameter or greater.
b) A bad mark on a white ceramic PC board shall be a black mark of 2.5 mm in
diameter or greater.
c) The bad-mark reader cannot recognize the smaller or faded marks. The
bad marks shall be clear and legible.
2) Figures 12.7.1 and 12.7.2 show the bad-mark sensor appearance. For details of
installation, see the explanation of the head section.

3) Adjusting the sensitivity of the bad-mark sensor
Note 1: The software automatically adjusts the sensitivity of the bad mark sensor
(see Section 7.2.2.13 "Bad mark sensor teaching").
CAUTION
The sensitivity adjustment shall be performed only by the authorized
technician who received training for the operation of this machine.
Take care that any person other than the operator does not operate the
machine to prevent accidental activation of the machine.

12.8 Handling HMS
The HMS (Height Measurement System) is an optional device used to detect the
height of a component such as a feeder pick position.
This optional device consists of two parts: the height sensor which is composed of
the sensor and amplifier, and the HMS board which controls the height sensor. To
use this optional device, install it on the head unit.
The amplifier of the height sensor and the controls and switches located on the HMS
board are all already set at the factory. Do not change their settings.

Figure 12.8.1
The HMS conforms to Class 3B Laser Safety Standard of JIS C6802.
It can be used safely when following the instructions described in this manual.
CAUTION
The laser beam used for the high sensor is invisible. Be careful not to
expose you to the beam or do not try to view the beam.
