1 Introduction

1.1 Validity

1.1.1Part number

This document applies to the following products:

Part number	Product
398-020	VGC402
398-021	VGC403

The part number can be found on the type label which is attached to one side of the unit.

1.1.2Firmware version

This Operating Manual is based on the firmware version 302-534-D.

If the unit does not work as described, please check if it is equipped with this firmware version. See Chapter 5.4.2 Firmware version (Pnr), 29.

1.1.3Type label

There is a type label attached to one side of the unit. In all communication with INFICON, please state the information on the type label. For this purpose you may want to copy the information into the space provided below:

1.2 Intended use

The VGC402 and VGC403 Vacuum Gauge Controller is a display and control unit for vacuum gauges made by INFICON.

It is used together with vacuum gauges of the PSG, PCG, PEG, MPG, CDG, BPG, BCG and HPG series and is used for total pressure measurements. The vacuum gauges must be operated in accordance with their respective operating manuals.

In the following, the VGC402 or VGC403 Vacuum Gauge Controller will be referred to as «Vacuum Gauge Controller».

3 Installation

3.1 Unpacking

1Visually inspect the transport packaging for signs of external damage

2Unpack the Vacuum Gauge Controller and put the packaging material aside

NOTE:

Keep the packaging material for later use. The Vacuum Gauge Controller must be stored and transported in the original packaging material only.

3Examine the Vacuum Gauge Controller for completeness

4Visually inspect the Vacuum Gauge Controller for signs of damage

WARNING

Damaged product.

Putting a damaged product into operation can be extremely dangerous.

Never attempt to put a damaged product into operation. Secure the damaged product from unintended operation. Send a damage report to the haulage company or the insurer.

3.2 Mechanical installation

The Vacuum Gauge Controller can be used as follows: As a desk-top unit, mounted in a control panel, or mounted in a 19" rack. In each of these cases you must pay attention to the following safety note:

CAUTION

Too high ambient temperature.

Exceeding the maximum permitted ambient temperature may damage the unit.

Make sure that the maximum permitted ambient temperature is not exceeded and that the air can flow freely through the louvers. Do not expose the unit to direct sunlight.

WARNING

Lower protection class of the rack.

If the product is installed in a rack, it is likely to lower the protection class of the rack (protection from foreign bodies and water) e.g. according to the EN 60204-1 regulations for switching cabinets.

Take appropriate measures to restore the required protection class of the rack.

Fig. 3-3 Mounting the unit in a rack

NOTE:

In order to reduce the strain on the front panel it is recommended to equip the rack chassis adapter with a guide rail.

NOTE:

For safe and easy installation of heavy rack chassis adapters, it is recommended to equip the rack frame with slide rails.

•Conductor cross-section 3 × 1.5 mm2 or larger

3.3.3Ground

The ground screw (Fig. 3-4, 11, Pos. I) can be used to connect the Vacuum Gauge Controller with the protective ground of the pumping station.

1If required: Connect the protective ground of the pumping station with the ground screw. Use a protective conductor.

3.3.4SENSOR

The SENSOR connection is used to connect the sensors.

For each channel, there are two connections available which are connected in parallel: An 8-pin RJ45 appliance socket and a 15-pin D-Sub appliance socket. See

Fig. 3-4, 11, Pos. A…C.

Pin assignment

Fig. 3-5 Three-conductor cable with protective ground (example)

WARNING

Mains power.

Improperly grounded devices can be extremely dangerous in the event of a fault.

Use three-wire mains or extension cables with protective ground only. Plug the mains cable into wall sockets with protective ground only.

WARNING

No mains fuse.

The Vacuum Gauge Controller is not equipped with a mains fuse.

The wall socket must be protected with a fuse (max. 10 A).

1Connect the European appliance connector of the mains cord with the mains connection of the unit

2Connect the plug of the mains cable with the wall socket

NOTE:

If the unit is installed in a switching cabinet, the mains power can be supplied via a switchable central power distributor.

CAUTION

Improper sensor.

Sensors which are not designed for use with the Vacuum Gauge Controller may damage the unit.

Operate the Vacuum Gauge Controller with proper sensors only. See Chapter 2.3.1 Sensor connections, 8.

CAUTION

Multiple connection.

Only one sensor may be connected to each of the channels. Otherwise the connected sensors will be damaged.

Never connect more than one sensor per channel.

Connecting

1Channel 1: Connect the sensor with to the CH1-A or CH1-B connection. Use a shielded 1:1 cable.

2Channel 2: Connect the sensor with to the CH2-A or CH2-B connection. Use a shielded 1:1 cable.

3Channel 3: Connect the sensor with to the CH3-A or CH3-B connection. Use a shielded 1:1 cable.

3.3.5RELAY

The switching functions and the error monitoring system influence the state of several relays inside of the Vacuum Gauge Controller. The RELAY connection (Fig. 3-4,

11, Pos. J) allows to utilize the relay contacts for switching purposes. The relay contacts are potential-free (floating).
