b. Zero shift value setting
Turn the machine power on and use the following procedure to make the setting.
1. Move from the measurement mode in which the measured value is displayed, to the
setting mode by pressing the arrow key. 1-H displays in the top level and the zero shift
value displays in the lower level.
2. Set the zero shift value to -1 mmHg.
(The value can be changed using the up/down key.)
3. The zero shift value is entered when the arrow key is pressed after which 1-H will display.
4. Set this value to zero. (If the value is zero to begin with this can be left as it is.)
5. Press the arrow key twice to return the mode to the measurement mode.
This completes the tray pickup check sensor settings.
  NOTE: This function can be switched on and off by means of a Proper data setting. However,
when this function is switched on, the tray discard operation cycle time will be 280 to
290 ms longer than the existing cycle time.
    • ON/OFF switching procedure
To set to ON add 4096 to Proper data item PLM?_Machine_Status (MQ2?_MASA) and then
transmit the Proper data to the machine. The "?" denotes the module number. Also note
that if this is not input the tray pickup check function will be OFF.
3) Operation check of the tray pickup check sensor
This operation check is used to verify that the tray pickup check sensor does not erroneously
detect a tray. It applies when the settings outlined in 2) above have been made. The tray
pickup check sensor will go off, the tray will be considered as having been dropped, and the
machine will enter the emergency stop status if the vacuum pressure differential (pressure
when the remover vacuum leaks completely versus the pressure when a tray is picked) falls
below 1 (mmHg). Although the cases in which this would actually be used are extremely
limited, the following precautions would apply if an ultra lightweight tray (less than 40 g)
were being used for which pickup is possible even in the presence of a slight vacuum pressure
differential (2 - 3 mmHg).
If the vacuum pressure differential does not stabilize and the tray pickup sensor is chattering
this may cause an unnecessary emergency stop of the machine to occur. If so use a dummy
tray, for which pickup is possible in the presence of a pressure differential of 2 to 3 (mmHg), to
carry out a tray pickup check sensor detection test.
The procedure for conducting such a test is described below.
a. First, use the unit operation command to chuck the remover to the head.
b. Set the MY02B REMOVER VACUUM I/O to ON.
c. Set the MY03F TRAY PKUP OSET to ON.
d. Verify that the MX027 TRAY PKUP CHK I/O is always OFF (no chattering) when the
remover has nothing picked.
e. Manually pick the dummy tray with the remover.
f. Verify that the MX027 TRAY PKUP CHK I/O is always ON (no chattering) when the
dummy tray is picked.
This completes the check operation.

   Use a dummy tray that satisfies the following conditions.
    • Vacuum pressure differential of approximately 2 to 3 (mmHg) between the all leak status
and the tray picked status
• Tray that does not drop as a result of its own weight
   As an example consider using the following as a dummy tray.
    • Styrofoam: Size 270 mm length x 130 mm width x 30 mm thickness approximately 15 g
Prepare two pieces each with 18 holes that have an inner diameter of 23 mm
(Total weight of about 35 g)
This styrofoam is used for the nozzles that have been shipped.
Overlap the two pieces of styrofoam and pick with the remover (pick the styrofoam so that
the hole near the center of the styrofoam is close to the center of the remover). Adjust the
two pieces of overlapping styrofoam so that the vacuum pressure differential between the
all leak status and the styrofoam picked status is about 2 to 3 (mmHg). (Use the styrofoam
holes as slits.)
Try using the styrofoam pieces adjusted in this way as a dummy tray.
[13-60] Reverse Transmission of Proper Data
1) After all of the Proper data items have been measured transmit the Proper data from F4G.
2) Recheck the transmitted Proper data and input suitable values for any Proper data items
that require revision.
After verifying the Proper data, transmit the Proper data again from F4G to the machine.

[Chapter 14] Obtaining a Trace List with PC
・[14-1] Summary
This section introduces the procedure to save the QO242 E trace list in the PC, in which
NTCC is installed, as a text file, instead of printing out by a printer.
・[14-2] Equipment
１．PC with windows and NTCC installed
２．Digital board(FUJI recommends a RS232C wide board) However, if RS232C(COM)
port for PC itself is used, a digital board is not necessary.
３．A transmission cable to connect QP242E and PC
EEHH1041(15m 25PIN−25PIN when using a digital board COM port )
EEHH1051(30m 25PIN−25PIN when using a digital board COM port )
EEHH1061(15m 9PIN−25PIN when using a PC COM port )
EEHH1071(30m 9PIN−25PIN when using a PC COM port )
The transmission cable used at present is also acceptable.
( Caution: A transmission cable used for MCS-C/C is not acceptable. )
４．QP242E connected to NTCC, which is the target machine to take trace.
５．A floppy disk, or another equipment to save the trace data.
・ [14-3] QP242E Setting
１． Disconnect the cable that is plugged to RS232C ch1 at the CPU board, and plug it to
RS232C ch2 at the CPU board.
２．Plug the transmission cable to DATA CONNECTOR placed behind ICM at QP242E
side.
(If you want to use the cable used as the transmission cable at present, cable
replacement is not necessary. Just keep the cable as the current condition.)
・ [14-4] PC Setting
１．Plug the transmission cable for PC side to the port which is not used for NTCC .
(If you want to use the cable used as the transmission cable now, plug the cable to
the port that is not used for NTCC. However, in case there is no empty port, keep
the cable at the current position.)
* When using the port used for NTCC, close the NTCC. However, by closing the
NTCC, other M/C production data are not available to trace. When using the port
which is not used for NTCC, closing NTCC is not necessary.
２．For Windows NT3.51
①．Start the communication software in PC.
Select［Program manager ］→［Accessories］→［Terminal］to start it.
②．Select [Setting] in the terminal menu bar. Set the items in the [Port Setting] as
followed.
Bits per second ９６００
Data bits ８
parity none
Flow control Ｘｏｎ／Ｘｏｆｆ
Stop bits １
Connect using ＣＯＭ？(Port at PC where the transmission
cable of the target QP242E is connected to.)
③．Select [File]à[Save as], and save the setting condition.
(It is useful to keep the setting conditions for trace port : trace.trm)
