Installing the

CMX 240 Controller

The Infinity CMX 240 (with or without a modem) is a unique controller. You can connect a terminal to it and program it just as you would an Infinity CX 9000 controller, yet it belongs on the Infinet. You can connect 32 or 64 controllers to the CMX 240, depending on which particular model number you have. From the CMX you can program the Infinet controllers.

This manual covers the following:

•Site/System Setup Requirements

•Installing the CMX 240 series controller

•Connecting to the Infinet

•Connecting to the TankNet

•Connecting to the Modem

•Powering Up the Controller

•Interpreting Status Lights inside Cabinet

Appendix A gives the pinouts for the RS-232 port cables.

Appendix B shows you how to set some probe switches.

Warranty Registration

Your warranty is effective for 18 months starting on the date the system is shipped.

Site/System Setup Requirements

Before you proceed to install the system, you should map out where you plan to install each controller, terminal/workstation, and modem. When planning the sites, be aware of any electrical interference that may occur. You also need to be aware of cabinet dimensions, power requirements, cable limitations, and environmental requirements.

Warning

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions in this manual, may cause harmful interference to radio communications. 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.

Note

This digital apparatus does not exceed the Class A limits for radio noise emissions from digital apparatus set out in the Radio Interference Regulations of the Canadian Department of Communications.

Avis

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables aux appareils numériques de la class A prescrites dans le Règlement sur le brouillage radioélectrique édicté par le ministère des Communications du Canada.

Warning

All wiring and installations must comply with local, state, and national electrical codes.

Warning about Telephone Service

Refer to the Infinity Modem Installation Guide for safety warnings and installation instructions.

In the event repairs are ever needed on any Infinity CMX 240 controller, they should be performed by Andover Controls Corporation or an authorized representative of Andover Controls Corporation. For information contact Andover Controls at 300 Brickstone Square, Andover, Massachusetts 01810.

Cabinet Dimensions

Each Infinity CMX 240 cabinet is approximately 15 × 19 × 4.75 in.

You can order the CMX 240 with or without the cabinet.

Controller Dimensions

Each Infinity CMX 240 controller without a cabinet is approximately 12.54 × 14.25 × 2.75 in.

Power Requirements

Warning

Be sure your installation complies with local, state, and national electrical codes.

Caution

The CMX 240 series controller should receive power from its own independent, unswitched circuit.

The CMX 240 requires 24/115/230 VAC +/-20%, 50/60 Hz rated at 30 VA with a modem and 20 VA without a modem.

Modem

You can use the Infinity modem with any CMX 240, but the modem is not required.

If you order any CMX 240 with the Infinity modem, the modem is already installed.

If you order any CMX 240 without a modem and then add the Infinity modem later, refer to the Infinity Modem Installation Guide for instructions on how to install the modem.

Infinet Cables

The maximum cable length for Infinet is 4,000 ft. at 19,200 baud (up to 32 Infinet controllers). You can extend Infinet beyond 4,000 ft. or put more than 32 Infinet controllers on less than 4,000 ft. by using the InfiLink 200 amplification module.

4	CMX 240 Series Installation Guide

Cables that form Infinet are 24-gauge, single-twisted-pair, tinned, shielded copper wire. Use the following cables1 or their equivalents:

Note

You must use shielded cables for Infinet to ensure compliance with the Class A FCC limits and to communicate reliably.

•Brand Rex # H 9002 (single-pair)

•Anixter # 9J2401021 (single-pair plenum cable)

The cable should have a nominal impedance of 100 Ω and a nominal velocity of propagation of 78%.

The capacitance of the Infinet cable should be smaller than or equal to 12.5 pF/ft between conductors and smaller than or equal to 22 pF/ft between the conductor connected to ground and the next conductor.

Number of Infinet Controllers on CMX Infinet

You can have up to 64 Infinet controllers on a single CMX Infinet.

Table 1 shows the various model numbers and the number of Infinet controllers you can have on each.

Table 1. Number of Infinet Controllers

Allowed on Various CMX 240s

No.	CMX Model	CMX Model with
Ctlrs	Standard	Command Mode
32	CMX 240	CMX 245
64	CMX 241	CMX 246

The differences between the CMX 240/241 and the CMX 245/246 are differences in what you can program them to do. The CMX 245 and 246 allow you to choose Command mode on a terminal connected to COMM2. For details, see the Infinity Controller Programmer’s Guide.

1. You can also use any cables you may already have in place for ACNET or LBUS.

TankNet and Probe Power Supply Cables

Refer to the probe documentation for information on TankNet and probe power supply cables. If you do not have this documentation contact MTS Systems Corporation at the following address:

Order Number—0592 550164 Revision B

Lightning Protection

Warning

When running cables (Infinet) between buildings you must install lightning arresters for Infinet to prevent electromagnetic disturbances.

Use lightning arresters at each point where Infinet cable enters or exits a building. Use the following arrester:

Two pair gas tube arrester, Andover Controls # 01-2100-299.

Building Ground Requirements

Warning

Be sure that all Infinity products from Andover Controls Corporation are grounded to true earth ground. This kind of ground protects the equipment from voltage transients and other power surges in the area.

We cannot guarantee that the controller system will operate as documented unless you properly ground all controllers.

6	CMX 240 Series Installation Guide

Warning

Be sure to have your grounds inspected before you begin the installation process to be sure your municipality follows the National Electrical Code. Many municipalities do not and often have substandard electrical grounds.

An example of a substandard ground is a galvanized steel cold water pipe. As the pipe corrodes, it does not act as a true ground. The corrosion acts as an insulator, raising the potential of the pipe with respect to the ground.

When lightning strikes in the area of the installation, it drastically changes the potential of the earth.

Since properly grounded Andover Controls units respond to changes in potential more rapidly than poorly grounded electrical systems, a poorly grounded building tries to reach ground through the Andover Controls system. The surge of current can destroy electronic components on the controller board. Surges of much lower potential than lightning also impact the reliability of Andover Controls equipment.

Inspecting the Ground

You can check your ground as follows:

1.Check your ground by first inspecting the building power distribution panel for earth ground termination. If the ground termination is any of the following, it is not adequate and must be corrected:

•Does not exist.

•Is connected to a corroded or galvanized pipe.

•Is connected using a small gauge wire (less than 14 AWG).

2.Be sure your Andover Controls cabinet is connected to the ground with a copper conductor that terminates at the distribution panel.
