1.3Damage Requiring
Service
Disconnect the product from the wall outlet and all power sources and refer
servicing to qualified service personnel under the following conditions:
1.When any cable or plug is damaged.
2.If any liquid has been spilled onto, or objects have fallen into, the
product.
3.If the product has been exposed to rain or water.
4.If the product does not operate normally even if you follow the
operating instructions. Adjust only those controls that are covered by
the operation instructions. Improper adjustment of other controls may
result in damage and will often require extensive work by a qualified
technician to restore the product to its normal operation.
5.If the product has been dropped or the enclosure has been damaged.
6.When the product exhibits a distinct change in performance. This
indicates a need for service.
Substitution or modifying parts can result in product
damage or personal injury due to electrical shock or fire.
•Install only those replacement parts that are specified by
Granville−Phillips.
•Do not install substitute parts or perform any unauthorized
modification to the controller.
•Do not use the controller if unauthorized modifications
have been made.
Failure to install appropriate pressure relief devices for
high−pressure applications can cause product damage
or personal injury.
For automatic backfilling and other applications in which
malfunction or normal process conditions can cause high
pressures to occur, install appropriate pressure relief devices.
Suppliers of pressure relief valves and pressure relief disks can be located
via an online search, and are listed on ThomasNet.com under “Relief
Valves” and “Rupture Discs. Confirm that these safety devices are properly installed before installing and operating the product. In addition, check
that:
1.the proper gas cylinders are installed,
2.gas cylinder valve positions are correct on manual systems, and
3.the automation is correct on automated gas delivery systems.
Vacuum gauges with compression fittings may be forcefully ejected if the
vacuum system is pressurized.

1.8FCC VerificationThis equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to Part 15 of the U.S. Federal
Communications Commission (FCC) Rules. These limits are designed to
provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment uses
and can radiate radio frequency energy and, if not installed and used in
accordance with this instruction manual, may cause harmful interference to
radio communications. However, there is no guarantee that interference
will not occur in a particular installation. Operation of this equipment in a
residential area is likely to cause harmful interference in which case the user
will be required to correct the interference at his own expense. If this
equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment OFF and ON, the user
is encouraged to try to correct the interference by one or more of the
following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
• Consult the dealer or an experienced radio or television technician for
help.
For information about FCC and EU compliance, see FCC and EU Installation Requirements on page 49.
The Series 358 Micro-Ion Vacuum Measurement System can operate one

Micro-Ion Gauge along with two Convectron Gauges simultaneously, or
one Micro-Ion Gauge along with one Convectron Gauge and one
Capacitance Manometer Gauge simultaneously.
Pressure readout is via three front panel displays, analog output, and
available computer interface.
The Series 358 Micro-Ion Vacuum Measurement Controller is a modular
instrument that can easily be customized to fit most user's exact needs.
Infrequently used controls are housed behind a hinged front panel, reducing
front panel clutter and allowing the Controller to reside in a half rack space.

System ComponentsInitial SetupInstallationBefore You Begin
3.1Controller SetupNow is a convenient time to make any required switch changes before
mounting the Controller in its desired location.
If the pressure display units of measure are correct (see Figure 3-1), and you
do not want to change the degas power timer from the factory setting of 10
minutes, skip to Process Control Setup on page 32.
Figure 3-1 Units of Measure Label
System ComponentsInitial SetupInstallationBefore You Begin
If you want to change the units of measure, the display rate, or the degas
timer, you must remove the top cover of the Controller.
3.2Top Cover Removal1.With power OFF, remove any cables from Controller rear panel.
2.Observe antistatic precautions to avoid damaging static sensitive
components inside the chassis. Use a grounded, conductive work
surface. Do not handle integrated circuits (IC) devices more than
necessary, and only when wearing a high impedance ground strap.
(A high impedance helps protect human life in case of inadvertent
contact with high voltage.)
3.Remove the four Phillips head screws identified in Figure 3-2. If the
unit is equipped with a rear bracket, remove the Phillips head screw on
the bracket, and slide the bracket off.
Figure 3-2 Location of Screws for Top Cover Removal
3.3Pressure Units Setup
If units of measure are as desired (see Figure 3-1), skip to Changing Display
Update Rate on Electrometer Module on page 30.
3.4Changing Units of
Measure for Electrometer
Module
Your unit will have been shipped from the factory preset to display the unit
of measure, Torr, mbar, or pascal, that you requested. Selection between
Torr and mbar units is done by adjusting the Micro-Ion gauge tube
sensitivity to the appropriate units. For example, a tube has a sensitivity of
20/Torr or 15/mbar. Thus, for this tube, adjusting the sensitivity for a display
reading of 2.0+1 will result in display of pressure in Torr (see Sensitivity Adjustment on page 99). Adjusting to 1.5+1 will result in display in mbar.
If you want to change pascal units, change the switch on the electrometer
module as follows:
1.Shut OFF power to the Controller.
2.Remove the top cover as described in Top Cover Removal on page 27.
3.Locate the Micro-Ion gauge electrometer module. See Figure 2-4 and
Figure 3-3.
4.Locate the Unit of Measure display units control switch.
5.Set the switch to the desired position: Off = Torr/mbar units;
On = pascal units.
You must also change the setting of the unit of measure switch on the
Dual Convectron gauge as described in Changing Units of Measure for Convectron Gauge on page 30.
6.To change the units of measure label on the front of the Controller,
open the door and lift the label card from its slot in the top of the front
panel. Units of measure labels are included in the mounting hardware
kit.

To adjust the overpressure shutoff point to a different level:
1.Maintain system pressure at the desired shutoff point.
2.Rotate the overpressure adjustment potentiometer fully
counterclockwise.
3.Turn ON the ion gauge.
4.Rotate the adjustment potentiometer clockwise slowly until the ion
gauge turns OFF.
3.6Changing Display Update
Rate on Electrometer
Module
When “ON”, the Slow Update switch on the electrometer module enables
pressure averaging. The display will be updated approximately every 3
seconds. When “OFF”, the update period is approximately 0.5 seconds.

3.7Changing Units of
Measure for Convectron
Gauge
The Series 358 Controller is shipped from the factory preset to display the
units of measure, Torr, mbar, or pascal, that you requested. To change the
units of measure for the Convectron Gauge:
1.Turn OFF power to the Controller.
2.Remove the top cover as described in Top Cover Removal on page 27.
3.Locate the Convectron gauge module. See Figure 2-4 and Figure 3-5.
4.Locate the mbar and pascal units switches.
5.Leave both switches “OFF” for Torr units. Turn ON the switch for either
mbar or pascal units.
6.Modify the units of measure of the electrometer module to be
consistent with the Convectron gauge. (See Changing Units of Measure for Electrometer Module on page 28.)
7.Slip the label card out of the top of the front panel and apply the
appropriate pressure units label. See Figure 3-4.
