1.2 Equipment Grounding
Proper Grounding
All components of a vacuum system used with this or any similar high voltage
product must be maintained at earth ground for safe operation. The power cord of
this product shall be connected only to a properly grounded outlet. Be aware,
however, that grounding this product does not guarantee that other components of
the vacuum system are maintained at earth ground.
Complying with the usual warning to connect the power cable only to a properly
grounded outlet is necessary but not sufficient for safe operation of a vacuum system
with this or any similar high voltage producing product.
Verify that the vacuum port to which the Ionization Gauge or Convectron Gauge is
mounted is electrically grounded. It is essential for personnel safety as well as proper
operation that the envelope of the gauge be connected to a facility ground. Use a
ground lug on a flange bolt if necessary.
1.3 Implosion / Explosion
Install suitable devices that will limit the pressure to the level that the vacuum
system can safely withstand. In addition, install suitable pressure relief valves or
rupture disks that will release pressure at a level considerably below the pressure
that the system can safely withstand.
1 Safety Instructions
Glass ionization gauges, if roughly handled, may implode under vacuum causing flying glass which
may injure personnel. If pressurized above atmospheric pressure, glass tubes may explode. A
substantial shield should be placed around vacuum glassware to prevent injury to personnel.
Danger of injury to personnel and damage to equipment exists on all vacuum systems that
incorporate gas sources or involve processes capable of pressurizing the system above the limits it
can safely withstand.
For example, danger of explosion in a vacuum system exists during backfilling from pressurized gas
cylinders because many vacuum devices such as ionization gauge tubes, glass windows, glass bell
jars, etc., are not designed to be pressurized.
Install suitable devices that will limit the pressure from external gas sources to the level that the
vacuum system can safely withstand. In addition, install suitable pressure relief valves or rupture
disks that will release pressure at a level considerably below that pressure which the system can
safely withstand.
Suppliers of pressure relief valves and pressure relief disks are listed in the Thomas Register under
“Valves, Relief” and “Discs, Rupture.”
Confirm that these safety devices are properly installed before installing the product. In addition,
check that:
a. The proper gas cylinders are installed,
b. Gas cylinder valve positions are correct on manual systems, and
c. The automation is correct on automated gas delivery systems.
d. Vacuum gauges with compression fittings may be forcefully ejected if the vacuum system is
Series 275 Gauges should not be used above 1000 Torr true pressure.
Series 275 Convectron gauges are furnished calibrated for N2. They also measure the pressure of air
correctly within the accuracy of the controller.
If accurate conversion data is not used, or is improperly used, a potential
overpressure explosion hazard can be created under certain conditions.
Do not attempt to use a Series 275 gauge calibrated for N2 to measure or control the
pressure of other gases such as argon or CO
to the other gas is properly used. See Section 5.3 on page 44.
If used improperly, Convectron gauges can supply misleading pressure indications
that can result in dangerous overpressure conditions within the system.
unless accurate conversion data for N2

Do not operate in an explosive atmosphere.
Do not operate the product in the presence of flammable gases or fumes.
Operation of any electrical instrument in such an environment constitutes a definite
safety hazard.
Do not use the product to measure the pressure of explosive or combustible gases or
gas mixtures. The sensor wire of the Convectron Gauge normally operates at only
125 ˚C, but it is possible that Controller malfunction can raise the sensor
temperature above the ignition temperature of combustible mixtures.
Danger of explosion or inadvertent venting to atmosphere exists on all vacuum
systems which incorporate gas sources or involve processes capable of pressurizing
the system above safe limits.
It is the installer's responsibility to ensure that the automatic signals provided by the product are
always used in a safe manner. Carefully check manual operation of the system and the set point
programming before switching to automatic operation.
Where an equipment malfunction could cause a hazardous situation, always provide for fail-safe
operation. As an example, in an automatic backfill operation where a malfunction might cause high
internal pressures, provide an appropriate pressure relief device.
The fumes from solvents such as trichloroethylene, perchloroethylene, toluene, and
acetone can be dangerous to health if inhaled. Use only in well ventilated areas
exhausted to the outdoors. Acetone and toluene are highly flammable and should not
be used near an open flame or energized electrical equipment.

Pressure readout is via a front panel digital display for the ion gauge, and analog outputs for either
the Convectron gauges or thermocouple gauges.
The 330 VGC is a modular instrument with infrequently used controls housed behind a hinged front
panel, thus reducing front panel clutter and allowing the VGC to reside in a half-rack space.
2.2.1 Degas Function
The 330 VGC has a factory installed resistance heating degas option. An interlock is provided to
only allow degas when the ion gauge tube is ON and displayed pressure is below 5 x 10

2.4.2 Mounting Configurations
Figure 2-2 illustrates the various configurations available for mounting the Series 330 Vacuum
Gauge Controller.
NOTE: The 330 controller should be mounted in a location with free air flow
and ambient temperature less than 40
The 330 VGC operates a Bayard-Alpert type or equivalent ionization gauge. It is ideally suited for a
nude ionization gauge such as the Granville-Phillips 274022 or 274023 which have an X-ray limit
in the low 10
pressures they provide longer operating life and greater burnout resistance.
When installing an ion gauge, note that if it is placed near the pump, the pressure in the gauge may
be considerably lower than in the rest of the system. If placed near a gas inlet or source of
contamination, the pressure in the gauge may be higher.
If an unshielded gauge is placed near an electron beam evaporation source or used in a sputtering
system, spurious electrons or ions may disturb the measurement. Screens or other shielding should
be placed between the gauge and the system if spurious charged particles or severe electromagnetic
interference is present. Consideration should also be given to electrostatic shielding of glass
tubulated gauges when measuring pressures near their x-ray limits.
Brooks Automation, Inc./Granville-Phillips offers 3 cable types for ion gauges. One has a standard
connector for the series 274 tubulated gauges; one has a standard connector for series 274 nude
gauges; and one has individual pin sockets for use with nonstandard pin configurations as well as
Granville-Phillips nude gauges.

Figure 2-3 shows typical gauge base configurations using the cables listed above and shown in
Figure 2-4, 2-5, and 2-6.
NOTE: To use the second filament of a dual
filament gauge, the cable connector at the
gauge is removed and rotated 180
reinstalled.
Do not attach cables to glass gauge pins while the gauge is under vacuum.
Accidental bending of the pins may cause the glass to break and implode.
Cables, once installed, should be secured to the system to provide strain relief
for gauge tube pins.
Ionization gauges are safe for use only if all exposed conductors on the gauge
and on controller and on vacuum system are grounded.

Improper grounding can cause product damage or personal injury.
• Follow ground network requirements for the facility.
• Maintain all exposed conductors at earth ground.
• Connect the power cord to a properly grounded outlet.
• Make sure the vacuum port to which the gauge is mounted is properly
grounded.
• Connect the gauge envelope to a facility ground. If necessary, use a ground lug
on the flange bolt or a hose clamp connected to the gauge/component.
High voltage can couple through a gas to the internal electrodes of a gauge. Do not touch the
exposed pins on any gauge installed on a vacuum system where high voltage is present.
Touching the pins on the gauge in a high−voltage environment can cause an
electrical discharge through a gas or plasma, resulting in property damage or
personal injury due to electrical shock.
Vent the vacuum chamber to atmospheric pressure and shut OFF power to the
controller before you touch the pins on the gauge.

2 Installation
The placement of a second ground wire (dashed line in Figure 2−7) between the
vacuum chamber and the 330 Vacuum Gauge Controller chassis is NOT safe −
large currents could flow through it.
After each maintenance/service procedure and before operating the controller
and vacuum system, make sure that your vacuum system and controller are
grounded as shown in Figure 2−7.
FAILURE TO DO SO COULD BE FATAL.
When high voltages are used within the vacuum system and the gauge envelope is not reliably
grounded through its vacuum connection, either a separate ground wire must be added, or the
envelope must be shielded to positively prevent human contact. The gauge envelope may be
grounded by using a metal hose clamp on the gauge connected by a #12 awg copper wire to the
grounded vacuum chamber. See Figure 2-8.
Figure 2-8Grounding a Convectron Gauge
1.Connect a heavy duty ground wire #12 AWG or larger from the ground lug on the back of the
Controller to your facility grounding electrode system. This will provide an earth ground for
the Controller in the event the interconnect cables are not in place. Do not connect the ground
lug to the vacuum system or other component. Connect it directly to the facility grounding
system such as a grounded outlet box or a grounded copper water supply pipe. Do not rely on
small metal water lines to ground a component. Later on someone may replace the metal
tubing with plastic tubing thus unwittingly causing a potentially dangerous situation.
2.Provide a connection to ground for other instruments with electrodes in the vacuum system
possibly exposed to high voltage electrical discharges.
3.Provide a connection to ground for each ungrounded metal component in, on or around the
vacuum system, including the gauge envelopes, which personnel may touch and which can
potentially be exposed to high voltage electrical discharges within the vacuum system. For
example, a metal bell jar resting on an organic O-ring must be connected to ground if a
Micro-Ion gauge is to be used or if other high voltage sources are present in the vacuum
system.
