32 Infinet controllers). You can extend Infinet beyond 4,000 ft. or put
more than 32 Infinet controllers on less than 4,00 0 ft. by using the In-
fiLink 200 amplification module.
4 CMX 240 Series Installation Guide
Cables that form Infinet are 24-gaug e, single-twisted-pair, tinned,
shielded copper wire. Use the following cables1 or their equivalents:
Note
You mu s t use s hie ld ed ca bl es f o r 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.

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 Infi nity products from Ando ver 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 grou nd all control lers .
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 mu nicipalities 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 ins talla tion, 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 Ando ver 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 grou nd
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.
CMX 240 Series Installation Guide 7
Environmental Requirements
The CMX 240 controllers operate in rooms with temperatures ranging
from 40 to 120°F 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 Guide for information on how to
design a configuration.
You put only one CMX 240 series controller on an Infinet. You connect
a terminal to the CMX.
You cannot connect an LBUS to a CMX 240 series controller. You can-
not have an Infinity CX 9000 controller on the same In fine t with a ny
CMX 240.
Find the tag attached to each controller that gives the number of the controller. Bef ore 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. You’ll need to know where your controllers are
located when you later assign a name to each controller and each input
and output.

probes. Refer to the manufacturer’s documentation for probe
information.
The TankNet requires a communications Stahl intrinsic safety barrier.
After you connect TankNet to any CMX 240 controller, you wire the
other end of the TankNet cable to the safety barrie r s.
The probe power supply cable requires a power supply Stahl intrinsic
safety barrier. After you connect the power supply cable to any
CMX 240 controller, you wire the other end to the safety barrier.
Figure 8 is an illustration of the safety barrier connection.

Powering Up CMX 240 Series Controller
Before you proceed, be sure the following are correct:
1. Be sure AC input voltage selection is jumpered correctly.
2. Be sure the AC power is wired properly. Check to be sure all three
wires have been connected.
3. Be sure the controller has a true earth ground.
4. Be sure you have used the proper cables and correct lengths.
5. Be sure the Infinet has been properly wired. Double check that the
ground wire is under the negative screw.
6. Be sure that Infinet cable shields are properly connected.
7. If you have a TankNet, be sure the TankNet, safety barriers, and
probes are properly connected.
If you h ave complet ed all prev ious section s in this manu al and inst alled
all Infinet controllers, you are now ready to power up any CMX 240
controlle r.
To start the controller, turn on the AC power source (or close the power
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 the Infinet is transmitting data.
CMX 240 Series Installation Guide 23
3. The RD lights begins flashing only if data is being received from
COMM1, COMM2, CUSTOM PORT, or the Infinet. This may not
happen immediately.
4. If the CPU light flashes every 0.1 s ec, it means the CP U has fai led 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 battery. The battery (6 V lead-aci d battery) is to the lower le ft in the
cabinet. You must connect the red and black wires, hanging from the
right side of the CMX 240 board, to the battery as follows:
1. Find the black and red battery wires that are already attached to the
right side of the CMX 240 series 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.
