Using the M4106nx

The M4106nx is a general purpose controller
that can be used for a variety of applications.
The M4106nx is part of the M-Line, which
allows a complete HVAC control system to be
built a piece at a time.

document on the Automated Logic website at
www.automatedlogic.com.

CAUTION Changes or modifications to this
unit not expressly approved by the party
responsible for compliance could void the
user’s authority to operate equipment.

The M-Line consists of several general
purpose controllers that provide different
input and output point combinations. The
M4106nx has

• four digital outputs

• ten universal inputs

• six analog outputs

The M4106nx provides the communications
circuitry, non-volatile memory, and
removable screw terminals for
I/O connections.

The M4106nx uses a 6.00g or later version of
the MNM Module Driver; for more
information, see the MNM Module Driver

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 instruction
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.

humidity, non-condensing.)

Before setting or changing the address, make
sure the M4106nx’s power is off. The
M4106nx only reads the address when the
module is turned on. After changing the
address, you must transfer memory to the
module. Refer to “Transferring Memory” on
page 9.

The M4106nx has two rotary switches for
assigning the module’s CMnet address. One
switch corresponds to the tens digit and the
other corresponds to the ones digit. For
example, if the module’saddressisthree,set
the tens switch to zero and the ones switch to
three, as shown in Figure 2.

Mounting

Screw the M4106nx into an enclosed panel
using the mounting holes provided on the
cover plate. Be sure to leave about 2 inches (5
centimeters) on each side for wiring.

Figure 2. Setting the module’s address

Power Wiring

Whenever possible, make sure the module’s
power and communications connections are
working properly before connecting any input
or output points.

CAUTION The M4106nx module is a Class
2 device (less than 30VAC, 100VA maximum).
Take appropriate isolation measures when
mounting the M4106nx module in a control
panel where non-Class 2 devices (for
example, 120VAC) or wiring are present.

You can power several modules from the
same transformer if you maintain the same
polarity.

The M4106nx’s operating range is 21.6VAC to

26.4VAC. If voltage measured at the module’s

Revised 3/29/00 • M4106nx 3 © 2000 Automated Logic Corporation

power input terminals is outside this range,
the module may not work properly.

1. Turn the module’s power off. This
prevents the module from being powered
up before the proper voltage is verified.

2. Make sure the 24VAC power source is off.

3. Connect the power wires to the module’s
power terminals labeled Ground and
24VAC (see Figure 1 on page 2 for
location).

4. Apply power to the transformer.

5. Make sure that 24VAC is present at the
module’spowerinputterminals.

Use a dedicated 22AWG to 18AWG twisted
pair wire for legacy CMnet (EIA-485) wiring.
For more information about CMnet wiring,
refer to the Technical Handbook or to ARC156
CMnet Wiring Technical Instructions.

1. Be sure the module’s power is off before
wiring it to the CMnet.

2. Check the network communication wiring
for shorts and grounds.

3. Connect the CMnet wires to the module’s
screw terminals as shown in Figure 3. Be
sure to follow the same polarity as the rest

of the CMnet.

6. Set the module’s address. Refer to
“Addressing” on page 3 for details about
setting the address.

7. Turn the module’s power switch on.

When the module turns on, the Run and
Power LEDs turn on. The Run LED begins
blinking and the Error LED turns off. See
Table 7 on page 10 to troubleshoot the
LEDs. If the module does not respond, call
Technical Support at [phone].

CMnet Communications

The M4106nx module can connect to the
CMnet at 9600 bps, 38.4 kbps, or 156 kbps.
When communicating at 156 kbps, the CMnet
uses a unique implementation of the industry
standard ARCNET protocol called ARC156.
For a summary of the differences between
ARCNET and ARC156, please refer to ARC156
CMnet Wiring Technical Instructions.

4. Make sure the module is configured for
the correct baud rate. All modules on the
CMnet must use the same baud rate.

On an ARC156 CMnet (156 kbps), set the
CMnet Mode jumper to ARC156 (see
Figure 4 for the switch’s location).

If you are using a legacy CMnet (9600 bps
or 38.4 kbps), set the CMnet Mode jumper
to Legacy 9600/38.4k, and use the baud
rate DIP switch to determine the baud rate
(see Figure 5 for the switches’ locations).

Revised 3/29/00 • M4106nx 4 © 2000 Automated Logic Corporation

You can verify that the M4106nx is
communicating on the CMnet by making sure
the CMnet transmit and receive LEDs are
active (see Figure 5 for location).

Inputs

The M4106nx module has ten universal
inputs to accept the types of signals listed
below. Refer to Table 2 for information about
wire length, gauge, and shielding.

• Thermistor: Precon type 2 (10kohm at
77°F). Input voltages should range
between 0.489V and 3.825V for
thermistors.

• 0to5VDC:Theoutputimpedanceofa0
to 5VDC source must not exceed
10kohms. The input impedance of the
M4106nx is approximately 1Mohm.

• 0 to 20mA: The input resistance on the
“A” input is 250 Ohms. The “B” terminal

supplies a voltage source to power the
4-20mA transducer. The “B” terminal is
capable of supplying 18 to 24VDC, but

Revised 3/29/00 • M4106nx 5 © 2000 Automated Logic Corporation

the total current of all “B” terminals
must not exceed 200mA. If the voltage
measured from the “B” terminal to Gnd
is less than 18VDC, you need to use an
additional external power supply.

4. For each input, enter the channel number,
offset, and gain on the Function Block’s
Parameter page in SuperVision. Valid

channel numbers are listed in “Channel

To verify each output’s operation, lock the

Function Block’s Parameter page, then make
sure the equipment actually operates as
specified.

Each digital output can be placed in Manual
or Auto mode by setting the HOA switches
(see Figure 1 on page 2 for the switches’
location). Table 3 shows the status of the
digital output based on the output’s
configuration and the HOA switch position.

You can monitor the status of the HOA
switches through SuperVision by assigning
each switch a digital input in the FB using
channel numbers 81 through 84. Channel 81

channel 82 corresponds to HOA switch two,
and so on.

An off status on these channels means the
HOAswitchisinAutomode.Anonstatus
means the HOA switch is in Manual mode.

Analog Outputs

The M4106nx module has six analog outputs
that support voltage devices in the 0-10VDC
range. The device that is being controlled
must have a minimum of 500 Ohms
resistance measured from its input to ground
and must share the same ground as the
module.

Although the M4106nx’sAnalogOutputs
were not designed to output current, it is
possible to use these outputs for current
mode devices. To drive a 20mA device from
the module’s analog output, the total
resistance of the load must be 500 Ohms. If
necessary, wire a 1/2 watt resistor in series
with the 20mA device as shown in Figure 10
on page 8.

For example, to drive a 20mA device that has
250 Ohms of resistance, wire a 250 Ohm
resistor in series with the 20mA device (250
Ohms + 250 Ohms = 500 Ohms total
resistance).

Transferring Memory

3. Transfer memory to the module.

• In SuperVision v3.0, click Tools ­Troubleshooting - Transfer Memory to
Module.

• In SuperVision v2.6b, download
memory for This Module.

4. When the memory transfer is finished,
check the module status report again.
Make sure the FB List shows all the FBs
you intended to transfer.

Troubleshooting

Formatting the Module

When you are unable to communicate with a
module, you can, as a last resort, manually
format the module to try to restore
communication. Formatting the module
erases all memory, so you need to transfer
memory back to the module once it is
formatted.

The M4106nx module can store up to 59
Function Blocks (FBs) and the MNM module
driver. If you have any problems transferring
memory to the module, contact Technical
Support at [phone].

1. Log in to SuperVision on a workstation
connected to the CMnet. You can also
connect directly to the module using the
Access Port; see “Communicating with the
Workstation” on page 5.

from the CMnet.

Tx - lights when the module transmits data
over the CMnet.
