Power Requirements

Warning

Be sure your installation complies with local, state, and national

electrical codes.

Caution

TheCMX 240 series controller should receive power from its own

independent, unswitched circuit.

The CMX 240requires 24/115/230 VAC +/-20%, 50/60 Hz rated at30 VA with a modem and 20 VA without a modem.

Modem

You can use theInfinitymodem with any CMX 240, but the modem is

not required.

If you order any CMX 240with theInfinitymodem, the modem is

already installed.

If you order anyCMX 240without a modem and then add theInfinity

modem later, refer to theInfinity Modem Installation Guidefor instruc-

tions on how to install the modem.

Infinet Cables

The maximum cable length forInfinetis 4,000 ft. at 19,200 baud (up to

32Infinetcontrollers). You can extendInfinetbeyond 4,000 ft. or put

more than 32Infinetcontrollers on less than 4,000 ft. by using theIn-fiLink 200amplification module.

www.PDF-Zoo.com


13/49


Cables that formInfinetare 24-gauge, single-twisted-pair, tinned,

shielded copper wire. Use the following cables1or their equivalents:

Note

You must use shielded cables forInfinetto 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 and a nominal

velocity of propagation of 78%.

The capacitance of theInfinetcable 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 64Infinetcontrollers on a single CMX Infinet.

Table 1 shows the various model numbers and the number ofInfinet

controllers you can have on each.

The differences between the CMX 240/241and the CMX 245/246are

differences in what you can program them to do. The CMX 245and 246

allow you to choose Command mode on a terminal connected to

COMM2. For details, see theInfinity Controller Programmers Guide.

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:

Lightning Protection

Warning

When running cables (Infinet) between buildings you must install

lightning arresters forInfinetto prevent electromagnetic disturbances.

Use lightning arresters at each point whereInfinetcable 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 allInfinityproducts 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.

www.PDF-Zoo.com


15/49


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 havesubstandard 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 corro-

sion 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 poor-

ly grounded building tries to reach ground through the Andover

Controls system. The surge of current can destroy electronic compo-

nents 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.

www.PDF-Zoo.com


16/49


Environmental Requirements

TheCMX 240 controllers operate in rooms with temperatures ranging

from 40 to 120F and with humidity between 10 and 95%, noncondensing.

Laying Out the Site Setup

You may want to draw a map of where you plan to put each controller

and store it in a notebook. If you have not already done so, read the

EnergyNet and Infinet Configuration Guidefor information on how to

design a configuration.

You put only one CMX240series controller on anInfinet. You connect

a terminal to the CMX.

Youcannotconnect an LBUS to a CMX 240series controller. Youcan-

nothave anInfinity CX 9000controller on the sameInfinetwith any

CMX 240.

Find the tag attached to each controller that gives the number of the con-

troller.Before you remove any tags, be sure the tag has all of the

following information on it:

Location of the controller.

Serial number. Model name and number.

Then collect the tags. Youll need to know where your controllers are

located when you later assign a name to each controller and each input

and output.

connection) and the controller starts automatically.

(The real-time clock is always running on battery power, independent

of AC power.)

The following occurs (also occurs when you press the CLEAR

MEMORY button):

1. The CPU light begins flashing and flashes every 0.2 sec.

2. The TD lights immediately start flashing to show COMM1,

COMM2, the CUSTOM PORT, or theInfinetis transmitting data.

3. The RD lights begins flashing only if data is being received from

COMM1, COMM2, CUSTOM PORT, or theInfinet. This may not

happen immediately.

4. If the CPU light flashes every 0.1 sec, it means the CPU has failed a

RAM or ROM test. Call your Andover Controls representative for

assistance.

Connecting the Battery

Once you have closed the AC power connection, you connect the bat-

tery. The battery (6 V lead-acid battery) is to the lower left in the

cabinet. You must connect the red and black wires, hanging from the

right side of the CMX 240board, to the battery as follows:

1. Find the black and red battery wires that are already attached to the

right side of the CMX 240series controller labeled 6V BATTERY.

2. Take the negative black wire from the controller and slip it onto the

black socket on the battery.

3. Take the positive red wire from the controller and slip it onto the red

socket on the battery.
