ACC EMX 150
Installation Guide

Your warranty is effective for 18 months starting on the
date the system is shipped.
ternal power supply source of 24 VDC and properly
connect the modules to it. See the ACC EMX Modules
Configuration Guide for more information.
Before You Begin
The EMX 150 consumes up to 55 mA at 24 VDC.
You can connect one or more EMX modules to most Infinet
controllers that have an expansion port. The particular controllers are covered in the ACC EMX Modules Configuration
Guide (also enclosed with this product).The configuration
guide also tells how many inputs and outputs are allowed for
any a particular controller. Before you proceed, be sure the
controller allows modules and the number and type of modules you plan to use.
Warning
Environmental Requirements
The EMX 150 operates in the same environment that any
Infinet controller operates in.
Output Characteristics
The voltage output has 5 mA maximum output over the
range of 0 to 20 VDC. The input impedance of the device
being controlled can be no less than 4000 Ω.
Resolution of each voltage output is 0.100 V or 100 mV.
Be sure wiring and installations comply with local, state,
and national electrical codes.

The circuitry that produces the 0 to 20 mA signal acts as a
“current sourcing device.” It sources the current to ground.

Be careful when unpacking the unit or units to not damage
the packaging material—you must reuse it if you ship the
product back for repair.
2. Connect to the Infinet Controller
Dimensions
Each EMX 150 module is approximately 6.13 × 4.88 × 1.52 in.
Power Requirements
The first two modules receive power from the controller
and operate on 24 to 26 VDC. You can add additional
EMX modules other than an EMX 150 if you have an ex-
Connect the module to the Infinet controller as outlined in
the steps that follow.
Caution
Be sure you disconnect the Infinet controller’s AC power
source before you connect any modules.

1.Look at the bottom panel of your Infinet controller. On
that panel is an expansion port in approximately the
center of the panel.
2.Look at the EMX 150 module. Notice that it has a
connector on the top and on the bottom. Plug the top
connector into the Infinet controller.
3.If you are connecting more than one EMX 150 module
to your Infinet controller, connect the second one to the
bottom of the first.
4.Set the BOARD switch to 1 on the first EMX 150 on the
controller, and the BOARD switch to 2 on the second
EMX 150. If you do not plan to connect more than one
EMX 150, you should set the BOARD switch to 1.
Never set two modules of the same model number to the
same board number.
3. Connect the External Power Supply
(if necessary)
If you are installing multiple modules, you may need an
external power supply. To determine what you need, refer
to the ACC EMX Modules Configuration Guide.
Figure 2 shows where you connect the external power supply
to the 2-pin Berg type connector on the EMX 150. It also
shows outputs, their potentiometers and override switches.
Figure 2. Location of External Power Connection
and Jumper for External Power
4. Reposition Jumper on One Module
The Berg type connector immediately below the external
power supply connection has a jumper that you reposition
to indicate you are using external power.
Figure 3 shows the jumper in the two possible positions,
one for the internal power supply, the other for the external.

Power Supplies

Each is set to the internal position when you receive it.
You change the jumper position only on the module or modules connected to the external power supply, not on any other
modules.
Note
You need to change the jumper position only on the module(s) actually connected to an external power supply. Never
change the jumper position of other modules.
Wire the Outputs
You can wire the outputs to either voltage or current sensors.

Caution
Each output ranges from 0 to 20 V. Before you adjust the
output, attach a Volt-Ohm Meter to the output.
Wire Current Outputs
Remember that the current sources to ground.

Do the same for output B. For more information on how
to adjust the outputs and assign output numbers, see the
Andover Controls Infinity CX Programmer’s Guide.
If you have problems with the Infinet controller after installing the module, see the Andover Controls Infinet
Controller Troubleshooting Guide.
Refer to the EnergyNet and Infinet Configuration and
Troubleshooting Guide for information on how to
troubleshoot network and power supply problems.
Warning
Note
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.
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
