the primary power supply
unit.
• Supply power to the connection terminal
of the primary power supply unit.
Although the [POWER
ON] button on the
operation panel is pressed,
power is not supplied.
• Adequate air pressure is
not set.
• Check the air pressure.
Main Pressure:
0.49 MPa (5 kgf/cm
2
)
Air Blowing Pressure:
0.015 MPa (0.15 kgf/cm
2
)
Pressure Switch:
0.39 MPa (4 kgf/cm
2
)
• The air source cock is
closed.
• Open the air source cock.
The main pressure is “0
(zero)”.
• Air does not reach the air
source cock.
• Check the air hose, etc.
• Power is not supplied. • Power up the machine as follows.
Set the power breaker crank to “ON” ( ).
Press and hold the [POWER ON] button
on the operation panel for more than 1
second.
Nothing is displayed on the
touch screen.
• The screen saver function
is activated.
• Touch the screen.
The operation panel and
the touch screen are un-
available for operation.
• Operation availability is
locked on the opposite
side.
• (The operation lock
(HD06) lamp is ON.)
• Press the [PNL CHANGE] button on the
opposite side and press the same button on
the other side (on the panel to be oper-
ated).
Vacuum Pressure System
Check whether the vacuum pressure is correctly adjusted. *1
Set the operation mode to “PLACE” by pressing the [PASS/PLACE
CHANGE] key at the “AUTO OPN. SUB-MENU” display and turn
off all vacuum valves ([LA1-AXIS VACUUM/VACUUM BLOW],
[LA2-AXIS VACUUM/VACUUM BLOW], [LB1-AXIS VACUUM/
VACUUM BLOW], and [LB2-AXIS VACUUM/VACUUM BLOW]
Keys).
Confirm that “OFF” is set in the “STATUS” text boxes at the
“MANUAL SUBSYSTEM OPERATION” display.
Confirm that the vacuum pressure is -93 kPa (70 cmHg) or more
(Vacuum valve fully closed).
When the vacuum pressure is too low, it is required to replace the
vacuum pump with a new one.
Consult our sales personnel for the detailed information on how to
replace or repair the vacuum pump.
Check whether the vacuum pump is producing any abnormal sound. *2
Catch the sound of the vacuum pump and confirm that the sound is
not abnormal.
When abnormal sound is produced, consult our sales personnel for
the countermeasures.
Check whether the filter of the vacuum pump is stained or clogged.
*3
Refer to “Vacuum Pressure System” in “8. Maintenance (Every 3
Months) of Section 1 in Volume 4” and inspect the filter.
