SAFETY

Do not use the Dual Capacitance Manometer Gauge Controller to

measure the pressure of ammable gases. Under certain unusual

circumstances ignition leading to an explosion could occur.

IMPORTANT SAFETY INFORMATION

Thank you for purchasing this equipment from Ideal Vacuum Products. We want you to operate

it safely.

hRead this manual before installing or operating this equipment.

Failure to follow the warnings and instructions may result in serious

injury or equipment damage.

hKeep this manual in a safe location for future reference.

hThis equipment should only be installed and operated by trained,

qualied personnel, wearing appropriate protective equipment.

hFollow all codes that regulate the installation and operation of this

equipment.

Do not use gauges with straight tubing and compression ttings

in a system that may develop positive pressures. The tube could

be rapidly forced out of the tting causing equipment damage or

injury to personnel.

Do not use the Dual Capacitance Manometer Gauge Controller in

the presence of toxic chemicals, such as organic solvents without

proper ventilation.

1. GENERAL INFORMATION

1.1 INTRODUCTION

The Ideal Vacuum Products (IVP) XGC-520 Dual Capacitance Manometer Gauge Controller

(DCM) is an inexpensive solution for pressure readout of up to two Capacitance Diaphragm

Gauges (CDG’s). The IVP DCM controller provides enhanced accuracy with intelligently designed

features for simple user control and easy system integration.

The IVP DCM is designed to interface with the popular Baratron®CDG’s from MKS and can read

full scale absolute vacuum/pressure ranges from 20 mTorr (2 x 10-4 Torr) to as much as 10,000

Torr (1x104Torr). Because CDG’s measure absolute pressure, they are gas type and composition

independent. Lookup tables and conversion factors are not required.

The DCM controller can supply two gauges, heated or unheated, with dual polarity voltage (±15

VDC at 1A total).

The unit has two analog output relays, each of which can be assigned to either of the two gauge

channels, and programmed to energize when a setpoint is reached. This exibility allows the user

to easily set up automated tasks, such as valve activation or energizing a turbomolecular pump

when an appropriate backing pump pressure is achieved.

Pressure measurement units (Torr, mTorr, mBar or Pa) can be set individually for each of the two

gauges.

All user dened settings are stored in non-volatile memory and do not have to be re-entered every

time power is cycled.

Our DCM is conveniently housed in a compact 1/8-DIN extruded aluminum enclosure for benchtop

or rack panel mounting.

The brilliant, blue LCD display is easy to read and displays vital system and controller information

at a glance. The intuitive front panel membrane switch interface allows the user to access and

adjust all parameters quickly.

Remote communication and control is achieved by RS-232 serial terminal software. Connection

is made via the rear-mounted DB15 or USB-B connectors. A variety of sensor and serial cables

are available.

The DCM has a built in universal power supply which accepts an input of 100-240 VAC, 50/60Hz

though its standard C14 receptacle. Included is a 2 meter long (6 ft.) 115 VAC input power cord

with US plug 5-15P to C13 Connector. For use in other countries, the user must supply a suitable

power cord.

1.5 PANEL MOUNTING

Standard 1/8 DIN enclosure panel cut out dimensions are 1.772” x 3.622” (45mm x 92mm).

Maximum panel thickness is 3/8” (10mm). To mount the DCM in a panel, unscrew the two 4-40

set screws at the back of the DCM Use a 0.050” hex wrench. Slide the rails out of the slots. Slide

the DCM through the front of the panel, back rst. Slide the two rails back into the slots. Replace

the set screws and tighten until the rails hold the DCM snug in the panel.

1.9 CUSTOM CABLES

If you are making your own sensor cables, follow these guidelines:

hUse only quality, metal braided, fully shielded, cables between the controller and gauge(s).

hFoil or spiral shielded cables perform worse than braided, and signal degradation may occur.

hCables must be properly grounded at both ends.

hConnectors must have a metal case or be fully shielded.

hThe cable’s shield must contact the case on its entire circumference.

hThe shield wire must be grounded before the signal wires exit the connector.

hThe ground wire should be the absolute minimum length within the connector.

1.7 BACK PANEL POWER AND I/O CONNECTIONS

The back of the DCM has the power, communication, and sensor gauge connections. The DCM

has a built-in universal power supply rated for 100-240 VAC, 50/60 Hz. The DCM accepts a

C13 plug. The RS-232 I/O (multi purpose) connector is a 15 pin D-Sub. It is used for both serial

communication and for the two analog relay outputs. The USB-B connector is used for remote

serial communications and for software updates. The 9 pin D-Sub connector is used to connect

the CDG sensor gauges.
