products.

（iv）
PM10U EBARA CORPORATION
WARNING To avoid any hazard induced by toxicity, flammability and
explosiveness of the process gases used in the tool, be sure to
operate the tool according to the operations safety guidelines
supplied by tool suppliers.
Appendix 6 lists typical process gases used in a
semiconductor-processing tool. However, details concerning
the tool gases and other concerns specific to your tool should
be directed to the respective tool suppliers.
WARNING Check for gas leaks after installing and maintaining the piping.
Gas leaks will result in the discharge of harmful and dangerous
substances and in abnormal reactions due to the ingress of air
into the pump. When checking for gas leaks by pressurization,
please pressurize by less than 0.05 MPa into the purge port and
do check.
WARNING Do not alter the pump member nor change any parts without the
EBARA's consent or approval.

Safety Interlocks
WARNING Check Safety Interlock functions periodically (every 6 months)
to confirm the interlocks will work correctly.
EMERGENCY OFF (EMO)
A manually activated button breaks a low-voltage control circuit that, in turn,
interrupts line power. Restarting the pump(s) requires a manual reset of the
twist-lock button.
NITROGEN FLOW LOW
A normally open flow switch breaks when nitrogen supply to the pump (oil
bearing(s) and inter stage injection) drops below its factory set point, opening the
motor starter relay(s) and shutting down the pump. Restoration of sufficient
nitrogen flow permits restarting the pump.
MOTOR OVERLOAD
Motor thermostat protect the pump motor from overheating due to extended
current draws in excess of the motor rating. Under a persistent overload
condition, motor thermostat opens a contact, which interrupts the motor run circuit.
A brief cool down interval permits restarting the pump.
OVER CURRENT PROTECTION
The nearly instantaneous current rise from a line-to-line or line-to-ground short
very rapidly opens a main fuse and interrupting power supply to the electrical
panel. Manual reset, which requires clearing the fault condition, is necessary
before restarting the pump.
