WARNING: Read this Manual before operation
Use this product only for its intended use as described in this manual. Do not use any other
connection methods that are not recommended by the manufacturer.
Introduction
This manual is intended for the installer of the product. He or she must be a skilled technician with a
minimum of installation knowlwdge with Micro Thermo or Echelon product.
The end user will never have to move, connect or disconnect physical part of the product.
The U700 is a monitoring industrial controller, one of the multiple combinaison of the new Micro
Thermo Technologies MT-700 product family.
It is made of a main MT-722A Controller (A may be another letter) and a MT-716U (16 universal input)
expension module.
U700 Installation
Mounting
The U700 Monitoring Node has two mounting options: DIN rail; or Direct Mounting by the eight screw
holes (four per controller module).
For DIN rail mounting, mount the DIN rail in the desired location and attach the two controller modules
to the rail separately. First install the MT-722A controller at the left end of the DIN rail. You may need to
pull the locker up with a flat screw driver. Then put the MT-716U beside the Controller. Ensure the
controllers’ communication ports are correctly aligned, and
gently slide the units together until the plastic housings are
flush.
For Direct Mounting, mount the controller modules separately,
remove all wire connectors before securing the MT-722A
module in the left place using (4) #6 screws. Align the
controllers’ communication ports, and push the MT-716U units
together until the plastic housings are flush. Secure the second
module in place using (4) #6 screws. Replace wire connectors.
Any combinason of MT-700 modules can be made as long as only one MT-722A is used per row and
placed at the left most of the row. If the MT-722A is loaded with a battery cell or if any relay of a of
MT-700 module is used to control voltage higher than 24V the entire row should be housed in an
electrical enclosure.

Basic Setup
Initial Controller Setup
With the controller wired and powered on, the U700 controller must now be installed through MT
Alliance™. In order to set up Alliance, you must have correct permissions to access Configuration mode
in the Subsystem that the controller is being installed.
1) Select the appropriate Subsystem for the points being monitored (e.g., Refrigeration).
2) Select Configuration mode.
3) Select the desired view and zoom level where the Sensor Node is installed.
Dropping a Sensor Node
To begin, an instance of the controller must be set up in Alliance. This is done by adding a node in the
Alliance view:
1) Drag a Node from the Component list into the view where the controller is installed.
2) In the “Pick Node Type and Model” window that opens, select:
Transceiver: TP/FT-10
Channel: select the correct network channel; default: Backbone
Node Type: Sensor Node
Manufacturer: Micro Thermo
Model: Univ Sen Node MT700 Vx.x
3) Confirm the Visibility and Appearance settings, and press ‘OK’.
NOTE: The node icon can be moved to a different position in the current view. While holding the CTRL
key, click-and-drag the icon to the desired location.
Installing the Node
Next, for the U700 controller to be paired with Alliance and the firmware installed on the controller:
1) Click on the newly created node icon.
2) In the configuration window that opens, give the controller a unique, meaningful name in the
‘Identification’field.
3) Select the ‘Commands/Status’ tab.
4) Click the ‘Install’ button. If prompted, click ‘Yes’ to save changes.
6) On the U700 controller, press the Service (Srv) button.
7) After Alliance finishes sending the firmware and configuration parameters, Alliance will return to
the Sensor Node Information window. Click ‘OK’ to close.
Adding Sensors in Alliance
Each sensor connected to the Sensor Node will have its own entity in Alliance. This entity hosts the
configuration settings for the particular sensor, and acts as a visual representation of the sensor status.
The following must be completed for each sensor:
Dropping a Sensor
1) Drag a Sensor from the Component list into the Alliance view where the sensor is installed.
2) In the “Pick Sensor Type and Model” window that opens, select:
Name: select the sensor type (temperature, pressure, etc)
Manufacturer: select the sensor manufacturer (Micro Thermo, Sporlan, etc)
Sensor Model: select the specific sensor installed
3) Leave all other defaults, and press ‘OK’.
NOTE: The sensor’s icon can be moved to a different position on the current view. While holding the
CTRL key, click-and-drag the icon to the desired location.

MT-700 series installer guide Page 7
Configuring a Sensor
1) Click on the newly created sensor icon.
2) In the sensor configuration window, give the sensor a unique, meaningful name in the
‘Identification’field.
3) Select the ‘Hardware’ tab.
4) Confirm the manufacturer and sensor model are correct from earlier.
5) In the ‘Sensor Node’ field, select the controller that this sensor is connected to.
6) In the ‘Sensor Node Input’ field, select the input location for the sensor. The inputs are
numbered sequentially, starting with two inputs on the Main controller and proceeding to the
first expansion module. The inputs are also identified –in parenthesis –by two numbers,
corresponding to the module number and input number.
For example: Input (1-2) is Input No. 2 on the Main Controller; Input (2-6) is Input #6 on the
second module.
7) Select the ‘Alarm’ tab.
8) Configure the sensor’s alarm settings, by either selecting a preset or manual configuration. To
select a preset: click the ‘Pick Alarm Settings’ button, select a preset from the list, and click ‘OK’.
Or to manually configure the alarm settings, fill in the following fields:
Description: (optional)
Optimal Value: specify the desired sensor reading –displayed on trend graph for reference
High/Low Limit: specify the upper/lower threshold, above/below which an alarm will be
generated
Set Time: specify the time delay, during which the sensor must remain outside of the high/low
limit, before an alarm is generated
Recall Time: if an alarm is Acknowledged in Alliance but the alarm condition persists, the alarm
signal will be re-activated after the delay specified here. This feature ensures alarms conditions
are not dismissed or forgotten without being resolved.
Priority Level: specify the severity of the alarm. Temperature alarms should be considered high
priority.
Relay: specify the external relay to be activated when an alarm is generated (optional)
9) Click ‘OK’ to close the sensor window. If prompted, click ‘Yes’ to save changes.
Basic Operation
Status
Controller
The U700 controller has five LED status lights. These indicators represent the basic operational status of
the controller.
The Main Controller Status LED shows the current programming status of the controller. In Normal
mode, the light will flash twice followed by a delay. This pattern repeats every two seconds. In Wink
mode, the light will flash fast for up to 60 seconds.
The Second Module Status LED shows the communication status with the main controller. The light
flashes green during normal operation, and red if communication is lost.
The Lon Rx/Tx LED shows activity on the LonWorks® network.
The RS485 Rx/Tx and Ethernet Act/Lnk LEDs are not used on U700 Monitoring Node.

MT-700 series installer guide Page 8
Alliance
Alliance utilizes the sensor icon to display general status information for quick view and monitoring.
Each sensor icon is color coded for its current state and, depending on the zoom level, displays the
sensor value and an image corresponding to the sensor type.
The sensor icon will appear similar to the following:
- The sensor is operating normal and is within all alarm setpoints.
- The sensor alarm is active and requires attention.
- The sensor alarm is in Recall mode; the first alarm has been acknowledged, but the cause
has not been resolved and the alarm has been reactivated.
- The alarm has been disabled, either temporarily or permanently, for this sensor.
- Communication has been lost with the sensor controller, and Alliance does not know the
current status of the sensor.
Clicking on the icon opens the Sensor Information window, where detailed status and sensor history is
available.
Trend Graphs & Sensor History
The ‘Graph & Log’ tab in the sensor configuration window provides access to the complete history of the
sensor. The graph displays sensor readings for up to five years, along with the optimal value, high/low
alarm limits, when the alarm was active, and the cumulative alarm time (if applicable). The graph’s
zoom level can be set to display between 1-Hour and 4-Days of data at a time; and the statistical data
displayed along the right-hand side is continuously updated to correspond to the time period of the
graph. For more in depth diagnostic, the ‘Trend Graphs’ button opens the Trends Graph window, where
the sensor’s value can be displayed simultaneously with any other MT Alliance™ saved point.
The lower section of the ‘Graph & Log’ tab provides a detailed list of all modifications made to the
sensor since it was installed. In addition to standard log events, new entries can be created manually;
this allows explanations, reminders, or general notes to be permanently recorded and attached the
individual sensor.
Reports
Sensors can generate automatic, printed reports. These reports can be generated upon
acknowledgement of an alarm, as a daily report, or both. To configure reports, open the ‘Details’ tab in
the sensor configuration window. In the upper right section, select the desired Reporting Preferences.
Additional Daily Report settings can be found on the Alliance ‘Reports’ menu.
Changing Settings
Many settings for sensors can be changed at any time, should the need arise. However, there are a few
exceptions:
1) The (hardware) Model cannot be changed on a Node after it has been dropped in Alliance. To
change hardware type, the node must be deleted and a new node dropped.

MT-700 series installer guide Page 9
2) The Subsystem cannot be changed on a Node after it has been dropped in Alliance. To change
subsystems, the node must be deleted and a new node dropped.
3) The sensor type cannot be changed on a Sensor after it has been dropped in Alliance. To change
sensors, the sensor must be deleted and a new sensor dropped.
NOTE: If a Node or Sensor is deleted in Alliance, its history and logs will also be removed.
Additional Features
Alarms
Alarm Set 2
In addition to the standard alarm threshold, the controller provides a second set of alarm parameters
that can be used to complement the primary alarm. The second set is usually configured with narrower
alarm limits, but a longer set time. This can be used to identify poorly performing equipment and warn
when product shelf life may be reduced. For example, the primary alarm can be set to activate if the
measured temperature is 15°F above optimal for one hour; but the second alarm can be set to activate
if the measured temperature is 8°F above optimal for four hours. This second condition may not
warrant a high priority alarm; but it can be a good indicator that the system needs attention.
By default, Alarm Set 2 is inactive and must be enabled on each sensor.
To configure Set 2, open the ‘Alarm Settings’ tab in the sensor configuration window. In the lower right
portion, click ‘Set 2 Active’ and modify the alarm settings as desired. Click the ‘OK’ button to save
changes.
NOTE: When a sensor is configured for Dual Use, Set 2 is used as the primary alarm for the second
temperature setting. For details, see the Dual Use Sensors section.
Cumulative Alarms
One advanced feature built into Micro Thermo monitoring is Cumulative Alarming. The Cumulative
Alarm monitors an input over an extended period of time (usually 24 or 48 hours), and calculates the
total time that the input exceeds the high/low limits. This differs from the standard alarm sets, which
require a continuous high/low measurement to activate. Instead of resetting every time the
measurement returns within limits, the Cumulative Alarm counts all current and previous exceptions
that occur within the Cumulative Period.
The Cumulative Alarm is an integral part of temperature monitoring, for maintaining food quality and
shelf life. The cumulative effect of temperature variations has a significant impact on refrigerated food.
The variations can also be an indicator of current or developing issues in the system –the instability
being caused either adjacent to the sensor or propagating from elsewhere in the system. In either case,
a Cumulative Alarm should be investigated to determine the cause.
To configure the Cumulative Alarm, open the ‘Alarm Settings’ tab in the sensor configuration window.
In the upper right section, select the alarm set to use for high/low limits and then specify the Set Time
and Cumulative Period parameters.
Disabling Alarms
The U700 Monitoring Node allows alarms to be disabled for individual sensors. Permanently disabling
an alarm inhibits all alarms for that specific sensor. This remains in effect until a technician manually re-
enables the alarm through Alliance. While an alarm is disabled, the icon in Alliance will appear light blue
for easy identification. However, if a sensor never requires an alarm (e.g., an auxiliary input), it may be
preferable to leave the alarm enabled with the alarm limits set to the sensor’s min/max range. This will
effectively disable the alarm, but will not affect the Alliance display.

MT-700 series installer guide Page 10
Alarms can also be temporarily disabled on sensors. This is often used during a maintenance call when it
is known that repair work will exceed the alarm set time (or recall time); in this case, the alarm is
disabled to prevent nuisance alarms. Temporarily disabling an alarm requires the technician to specify
an end time. At this time, the controller automatically reactivates the alarm.
To disable an alarm, open the ‘Alarm Settings’ tab in the sensor configuration window. In the upper left
portion, select ‘Disable Alarm Permanently’ or ‘Disable Alarm Temporarily’. Specify a reason (optional)
for the action, which will be visible to other users and recorded in the historical log. When disabling
temporarily, specify the end time. Leaving this at the default value will cause the alarm to remain
enabled.
NOTE: The temporary alarm details are stored in volatile memory on the controller. This information
will be lost if the controller is reset –either through the Alliance software, at the board, or if power to
the board is interrupted. When the controller is reset, it resumes all alarm settings. However, Alliance
may still show the alarm as disabled until the end time is reached.
Dual Use Sensors
The U700 Monitoring Node includes Dual Use capability for each sensor on the controller. Dual use
sensors allow for two sets of alarm limits to be configured and stored, with only one applied at a time.
When an assigned switch is toggled (either a software or physical switch), the controller automatically
applies the sensor’s alternate alarm settings. When the switch is toggled back, the controller returns to
the primary settings. This feature allows for quick, error-free changeover in dual use equipment.
Each dual use sensor must be associated with a switch. But one switch can control multiple dual use
sensors, including sensors on different controllers. At any point, a sensor can be changed back to Single
Usage, and the Alarm Set 1 settings will be retained.
To configure a sensor for dual use, first open the ‘Details’ tab in the sensor configuration window. In the
lower right section, select Dual Usage. Open the ‘Hardware’ tab and locate the Dual Use Switch settings
in the top right. For a physical switch, select the Hardware Switch option and then specify the Sensor
Node and Input where the switch is wired. For a software switch, select the Software Switch option.
When the software switch is enabled, changing the dual use from Set 1 to Set 2 is as simple as clicking
on an icon. Click on the sensor icon in Alliance to open the Sensor Information window. At the bottom,
center of the window, locate the two alarm settings with the image of a light switch between. Click on
the desired alarm setting to activate that Alarm Set. Alternatively, click on the switch icon to toggle back
and forth between the two settings. Click ‘OK’ and save modifications when complete.
Remote Sensors
The U700 monitoring node includes the capability to monitor network variables, in the same way the
controller would monitor the values from a physical sensor. This Remote Sensor feature allows the MT
Alliance system to: (1) record history and generate alarms for Calculation Block values; (2) generate
custom alarms for sensors connected to other Micro Thermo Technology controllers, without needing to
add duplicate sensors.
To configure a remote sensor, open the ‘Details’ tab in the sensor configuration window. In the Source
section, select Remote. Open the ‘Hardware’ tab and select the Sensor Node and Input (under Primary
Resource) where the sensor value will be simulated. In the Remote Source section, select the source
type and location from where the value is generated.
NOTE: Remote sensors utilize the same resources on the Sensor Node as a physical sensor. Therefore, a
remote sensor requires an open input on the controller; and a physical sensor cannot be assigned to an
input already assigned to a remote sensor.

MT-700 series installer guide Page 11
Calculation Blocks
The Calculation Block provides basic mathematical functions, which allow the U700 controller to
calculate the Minimum, Maximum, or Average of specified values. Each block accepts up to 26 inputs,
which can be a combination of: local sensor values, remote sensor values, network variables, and results
from another calculation block (local or remote). The result is calculated and available through a new
Remote Sensor or the nvoUnivCalc network variables. Each U700 controller features four Calculation
Blocks.
To configure a Calculation Block, open the node configuration window and select the ‘Calculation’ tab.
Local and Remote resources must be configured before the calculation blocks can be set up. For
Remote sources, click one of the Remote Source buttons and specify the Type and Source. After all
sources are set up, click one of the Calculation Block buttons. Give the block at Description, check all of
the Sources to use in the calculation, and specify the Type, Operator, Range, and Send on Delta values.
NOTE: The standard calculations operations cannot be performed on a switch-type (on/off) input.
Instead, when ‘Switch’ is selected, the Calculation Block allows the following bitwise operations: AND,
NAND, OR, NOR, XOR, XNOR.
NOTE: Calculations can only be performed on inputs of the same data type. MT Alliance™ enforces this
rule, and will only allow the user to select inputs that match the specified data type.
