WARNING

1.4 Pressure Relief Devices

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.

1.8 FCC Verification This 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.

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.

Chapter 3 Initial Setup

3.1 Controller Setup Now 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 Components Initial Setup InstallationBefore 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.

3.2 Top Cover Removal 1. 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.

Do not remove the two lower front screws

3.3 Pressure 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.

3.4 Changing 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.

3.6 Changing 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. Refer to Figure 3-3 on page 29.

3.7 Changing 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.
8. Replace the top cover as described on page 47.
