PM10U

EBARA

CORPORATION

P.3

3. Product Description

3.1 Outline

These pumps have a compact design and includes various sensors and controls to enhance reliability and operation.

3.1.1 Pump Module

The pump is Roots type vacuum pump which rotates a pair of non-contact multi-stage rotors synchronized by timing gears. The timing gears and bearings are enclosed in a compartment which is independent of the casing. For lubrication Perfluoro-Polyether (PFPE) oil and grease are used. The pumps of this series are factory filled with lubrication oil. Use only the recommended lubrication oil grades shown in specification Table 3.1 for replenishing or replacing.

3.1.2 N2 Gas (EV-S**P / EV-S**N)

Introduce nitrogen gas to dilute the hazardous gases to an unharmful level. Properly connect the nitrogen gas line to the purge port provided according to the instructions in Table 3.1 and the descriptions in Section 4.2.3. In the cases the gas concentration may become higher than the specified for safe gas exhaust, introduce the nitrogen gas to lines to the exhaust outlet. The tool user shall provide the purge port for this purpose.

N2 gas is also required to supply to seal the shaft section. This protects the penetration to bearing section, such as corrosive gas. To reduce pump corrosion due to process gas or accumulation of reaction by-products, N2 gas is supplied to each pump component as dilution purge gas. Stopping the dilution N2 with a selector valve can save N2 gas, when process does not produce corrosion and reaction by-products. The correct amount of N2 gas is supplied for those two types of purge operation, by adjusting the regulation pressure to the specified value. The nitrogen gas selector is locating on the right side of the unit, facing the utility connectors. It is under the outer cover.

PM10U

EBARA

CORPORATION

P.4

3.1.3 Cooling Water

Because the pump compresses gas from a vacuum to atmospheric pressure, compression heat is generated. Therefore cool the pump with cooling water. The cooling water connector takes the form of a coupler for easy connection and disconnection.

3.1.4 Exhaust

A check valve is built into the pump unit to prevent reverse flow of gas from the exhaust through the pump to the vacuum chamber when pump is stopped.

3.2 Control System

These pumps have a built-in unit consisting of a Circuit Protector (CP), Noise Filter (NF), control source. To improve reliability and safety, the condition of each utility and pump section is monitored by a sensor. During pump operation all operating conditions are monitored, including power supply, cooling water flow, N2 gas flow, casing and motor coil temperature, motor speed, and electric power for motor. Continuous operation is possible when there is a momentarily power failure (170V or less) of 1 sec or less.

3.2.1 Warning

To assure the reliability of the pump as a vacuum exhaust system, the pump protection system generates two levels of alarm： WARNING and ALARM.

PM10U

A WARNING signal is generated when pump operation exceeds the normal range. It therefore only draws attention that the normal operating values are not adhered to but does not signify that danger is imminent. The pump will continue to operate in this condition. An ALARM signal output is generated and the pump will stop automatically when the upper mechanical safety limit is reached during pump operation.

EBARA

CORPORATION

P.5

When an ALARM output is suddenly generated, while the plant unit is operational, a WARNING signal will be generated to ensure that the plant operation is not discontinued. This enables the operator to check the pump after the equivalent of one cycle has been completed. Be sure to contact EBARA Corporation for details on checking the WARNING and ALARM setting conditions.

3.2.2 Operation Status Control

The sensor data are displayed on the LCD provided on the controller to facilitate operation status control and daily inspection. All WARNING and ALARM signals are displayed on the LCD. For remote operation and monitoring, the signals are available as individual and group outputs.

3.3 The way of pump moving

3.3.1 Preparation

Before pump moving, all adjuster feet shall be raised fully at four places. In case of being not raised fully, pump may be tripped over by obstacle on floor.

PM10U

EBARA

CORPORATION

BBBB

P.6

3.3.2 Moving method

Move pump slowly by pushing eye bolt toward direction A. Be sure not to be caught by toes. If pump needs to be moved toward direction B in order to be set at a corner or narrow spaces, two persons shall move the pump by pushing its terminal portion alternately as directed below.

AAAA

If pump needs to be moved on steps or ditches, spread steel plate or the like which can sustain the pump weight over the steps / ditches and pump shall be moved on it by two persons with care.

Steel Plate

If pump should lose its balance when moving and start tripping over, never try to sustain the pump, get away from the pump immediately.

3.4 Release and shut off residual internal energy

WARNING To avoid dangers potentially encountered during maintenance,

transportation or storage, follow instructions below to shut off power.

WARNING Capacitors within the control panel retain residual energy after

interruption of power supply. Wait five (5) minutes after shutting off breaker before opening the control panel. Carefully check that bleed circuits have discharged the residual energy before servicing the control panel.

WARNING To comply with SEMI S2, install lockable shutoff devices on electrical,

nitrogen and cooling water supplies. These devices should be adjacent to and within sight of the pump.

3.4.1 Electrical Power - Lockout and Tagout

Lock the branch circuit in the OFF position and tag it out to perform maintenance or troubleshooting.

1. Verify that the LCD display is lit (confirming that pump is powered).

2. Turn the branch circuit disconnect off.

3. Insert padlock through holes provided on locking device. Close padlock and attach tag.

4. Keep the key with you while working. Prepare the tagout label per factory procedures.

5. Verify that LCD display is unlit (confirming that pump is unpowered).

6. If unable to confirm interruption of power via LCD display, use a voltmeter to probe contacts at Connector CN-C. Potential between any two pins indicates that electrical power to the pump is not interrupted.

7. The Lockout/Tagout procedures must comply with OSHA 29 CFR 1910.147 and 1910.331-335
