The MHTC Nortec Links XPS Option allows for the integration of a MHTC Series humidifier within a BACnet, Johnson N2 or LonWorks network. This option features a gateway that has the capability of converting information from the host Modbus protocol to a specified secondary protocol.
The following protocol options are available, and must be specified at time of order:
Table 1: Protocol Options
Multi-Unit Systems (“Master/Slave”)
Up to 8 humidifiers can be chained and monitored through a single Links XPS package. In this configuration, the unit with the Links XPS package is designated the “Master Unit”, while the remaining 7 humidifiers are configured as “Slaves”. The master unit is connected to the Building Management Systems (BMS). Each unit is separately addressed, it is possible to monitor and control each unit individually.
Different networking configurations may be achieved depending on the type of network being used. One networking example could have a Gateway installed inside the lead unit, which could then be daisy-chained to successive units. In turn, the lead unit would connect to a Building Management System (BMS) network via a shielded, twisted-pair connection. Please see wiring section for additional detail. A second example could have a series of units directly connected to an Ethernet network. This is only possible for BACnet communication and is essentially referred to as a BACnet/IP configuration.

Installing Links XPS into the Control Cabinet
If the Links XPS package was included with the original unit order, the necessary hardware will have been factory mounted and wired into the MHTC control cabinet. In this case, please skip ahead to the Wiring section for information on how to complete connections to the building automation system.
If Links XPS is being retrofit, or added to an existing MHTC unit in the field, follow the steps below prior to connecting wiring to the building automation system.
Mounting the Links XPS Assembly
Caution: Disconnect electrical power from humidifier before performing work inside control cabinet.
Locate the MHTC control panel and turn the power switch to the off position. Ensure that the power is also turned off at the breaker panel to prevent electrical shock. Open the control cabinet by loosening the screws on the on right side of the cabinet and sliding the brass lock clip out of the way.
MHTC ReFlow Models
1 Using the 4 plastic standoffs and plastic screws provided, attach the Links XPS module to
the steel back plate in the location shown in Figures 1and 2.
2 Secure the XPS transformer into the location shown in Figures 1 and 2. Use the two #6-32
thread cutting screws provided to secure the transformer in place.
3 Install the XPS Terminal strip onto the DIN rail at the bottom of the control cabinet as shown
in Figure 1. It may be necessary to remove one or both of the rail locks and shift the entire control terminal strip over to accommodate the XPS terminal strip.
Note: The exact location the XPS transformer may vary depending on the revision of back plate. Also, units produced before August 2011 may not have the holes for the XPS module and transformer. These models will require new holes to be drilled during installation.

MHTC Flow Models:
1 On MHTC Flow models, Links XPS replaces the remote fault relay board. Remove the
remote fault relay board indicated in Figure 3 and disconnect the cable.
Underneath the remote fault relay board, the 4 holes for the XPS module and two holes for the XPS transformer should be visible. Depending on the revision of the backplate these holes may be in different configurations or may not be present at all. In the case of the
latter, drill 4x ¼” holes to accommodate the XPS module. Subsequently drill 2x 9/64” holes
to accommodate the XPS transformer.
2 Using the 4 plastic standoffs and plastic screws provided, attach the Links XPS module to
the steel back plate.
3 Secure the XPS transformer using the two #6-32 thread cutting screws. 4 Install the XPS Terminal strip onto the DIN rail at the bottom of the control cabinet as shown

Configuring the Humidifiers
The PCB processor board will need to be configured to work with the Links XPS modules. Additionally, Nortec Links XPS can connect to a maximum of 8 units from a single Links XPS gateway. If slave units are being used it is necessary to set the address of each slave module. The address should be the number the nit will have on the networked chain.
Links XPS can be used for control, monitoring, or both. To set the control mode on the humidifier, on the humidifier refer to the procedure on page 52 of the MH2 Installation and Operation Manual to enter the controls menu.
If you would like to control the humidifier directly by signal writing values over the Links XPS package set the Signal Source to Modbus. The humidifier will now look for values to be written to the humidifier.
If you would like to use an analog control signal (from a wall stat or building automation system) leave Signal Source setting to Analog and then set Hum. Control and Controlsign. to match the type of controls being used. Ensure that controls are physically wired to terminals 3 and 4 on the DIN rail terminal strip.
To set the humidifier to recognize the Links XPS package:
1 On the humidifier keypad, Press the menu button on the keypad and scroll to the User menu
using the arrow keys. Press Set to enter the User menu.
2 When prompted for a password, use the arrow keys to enter 8808 and press Set to confirm. 3 Scroll to the Modbus menu and press Set to enter the menu. 4 Set the Parity to None1. 5 Set the Modbus address of the lead unit to 1. Repeat this step for any slave humidifiers,
taking care to assign each slave unit a unique and sequential number. For example if the lead is 1, subsequent units should be 2, 3, 4, etc. Note: Ensure that no units share the same Modbus address.
6 Place the appropriate Unit Identifier label on each humidifier. These laps should match the
Modbus address for that humidifier and should be placed in a visible location.
7 Connect the slave humidifiers (if applicable) to the Nortec Links Module. A twisted pair cable
should be used so that the Net (+) terminal on the Links module should connect to the Net (+) terminal on the slave unit (NHTC). The Net (–) terminal on the module should be connected to the Net (–) terminal on the slave unit. Refer to the Links XPS wiring diagram for more information.

Wiring
BACnet MS/TP, Johnson N2, and LonWorks
Links XPS is pre-installed and factory wired. Connections must be made between the master humidifier and the BMS, and the master humidifier and any slaves that may be present.
Up to 8 units (1 master, 7 slaves) may be connected to a BMS through a single gateway in the master unit. The units are daisy chained via the Links XPS terminal strip. The wire shield should only be connected at one end per pair of units when “daisy chaining”.
Table 2 refers to the recommended wire types and maximum recommended lengths from the Nortec Links XPS module to the Building Management system. Communication between the humidifiers and Nortec Links XPS will occur via a EIA-485 signal type. Nortec recommends using a 18-24 AWG shielded, 120 twisted pair wire between the lead humidifier and each of the slave humidifiers. Total cable length runs between the Nortec Links XPS module and the furthest slave humidifier should not exceed 2,000 feet. Signal boosters or repeaters may be necessary for longer wire runs or where electrical noise interference is prevalent.
Table 2: Recommended Wire Types and Lengths
Links XPS for MHTC | 18

BACnet/IP
A standard CAT-5E cable with an RJ-45 (Ethernet) jack is to be connected to the Ethernet port on the Links XPS module. Refer to wiring diagrams in this manual.
Cable Shielding
The cable’s shield should be connected to the shield terminal at the BMS system only, and not
the Links XPS module.
As well the cable shield should be connected at the lead unit only and not at subsequent units.
For long chains the shield would appear as:
Unit 2 to Master - Shield connected at master only.
Unit 3 to Unit 2 - Shield connected at unit 2 only.
Unit 4 to Unit 3 - Shield connected at unit 3 only.
And so forth.

Gateway Configuration
Protocol configuration is completed at the factory, prior to final testing. If configuration information was supplied at the time of order, the units will be configured for plug-and-play installation with no further configuration required. If this information was unavailable, it will be necessary to configure the addressing parameters.
BACnet IP systems will require a static IP address to communicate on the network, and may
require a device instance and MAC address
BACnet MS/TP and Johnson N2 systems require both a device instance, MAC address and
a baud rate to be set.
LonWorks systems automatically detect network address parameters and do not require
configuration.
Changing BACnet Device Instance and BACnet MAC Address
The initial step is to determine if both BACnet Device Instance and MAC address can be the same value. If not, skip to Part B. If yes, continue with Part A using solely the small dipswitches.
Part A: Device Instance and MAC address same value
The device instance and BACnet MAC address can be easily changed to the same value using the dip switches (SW3 Bank 1 through 8) highlighted on figure 10. Notice these are the smaller dipswitches, not the larger ones.
Figure 15: Dip Switches for BACnet Address Changes
Links XPS for MHTC | 20
Page 24
Figure 16: Respective Address and Baudrate Dipswitches
These switches allow you to set a binary value for the device instance between 1 and 127 inclusively. To set the device instance to a value outside of this range, skip to PART B.

After an address change has been made, the Links XPS module must be power cycled for the change to take effect. The module may take up to 60 seconds to restart after a power cycle.
Changing Baud Rate (BACnet MSTP, Johnson N2, LonWorks)
The baud rate for communications must be changed through dipswitches (SW4 Bank, 1 through
4). Refer to figure 16 for location of the dipswitch.
By adjusting the settings according to the table 5, the baud rate can be changed. The Baud rate must be set to exactly the same baud rate as your Building Management System. Communication performance varies with building automation system manufacturer and some experimentation with other baud rates may be required to obtain the best performance.
Table 5: Common Settings
After an address change has been made, the Links XPS module must be power cycled for the change to take effect. The module may take up to 60 seconds to restart after a power cycle.

Network Integration
LonWorks.xif file
To facilitate the integration of a LonWorks unit within a network, it may be desirable to obtain an External Interface File (XIF). Files of type .xif are used to convey the resources, specific objects and data types which a LonWorks device possesses. The .xif file allows a network integrator to simulate the presence of a networked humidifier even if it is not yet physically connected to the network. In fact, if the integrator has the .xif files of all network devices, a complete system could be simulated and configured off-line. Once the configuration is done, the integrator's software tool can be connected to the actual system and the configuration information can be downloaded.
Retrieving XIF File Instructions
The XIF file can be retrieved directly from the Links XPS Module. A Windows based laptop and an Ethernet cable are required for this process.
This process requires the “Remote User Interface” tool from Protocessor described earlier in this manual. It is available by visiting www.protocessor.com/tech-support/utilities-and-design-
documents.php and download and install the “Utility” software.
Once this software has been installed, follow the following procedure:
1. Locate desired MASTER humidifier that contains the Links package. Ensure unit is powered
on and remove the panel on the RIGHT side of the humidifier. Locate the Links package inside of the unit.
2. For LINKS XPS packages (gateway device on its own), connect the CAT5 cable directly into
the Ethernet port on the gateway.
3. Connect other end of CAT5 cable to the Ethernet port on the laptop.
4. Run the “Remote User Interface” utility by double clicking the shortcut on your desktop (or
Start>Programs>Fieldserver Utilities>Remote User Interface)
5. The program should automatically recognize connected humidifier and bring you to the
“Main Menu”. If it does not, contact Nortec Technical Services at the number on the back

In the variable name, “_x denotes the humidifier number. If there is only one humidifier, all variable
names will end in “_1”. If two units are networked together, see Figure 4, the second unit’s variable names will end in “_2”. For 3 networked units, “_3” and so on. If unsure of the unit number, each unit will have a
label, in the electrical compartment close to the terminal strip, indicating the device instance of each humidifier.
BACnet Pics and Bibs
The Protocol Implementation Conformance Statement or “PICS” describes the BACnet
capabilities of a particular BACnet implementation. It is a written document, created by the manufacturer of a device, which identifies the particular options specified by BACnet that are implemented in the device.
BACnet Interoperability Building Blocks (BIBBs) describe a list of services a BACnet device provides. The main areas that the building blocks are concerned with include: data sharing, trends, schedules, device and system management. BIBBs help specify the interoperability capabilities of a BACnet device. Please contact the factory to obtain a PICS statement or BIBBs profile.
Variable Definition
Nortec Links XPS is capable of communicating a variety of variables for each unit that is
connected to it. For a variable listing and definition refer to Table 6. Network variable addresses for the humidifiers may be seen in Table 7 to Table 14.

Humidifier-to-Humidifier Connection:
Each individual humidifier linked to lead unit.
Connection must be daisy-chained from the lead unit to the end unit, with shield wire connected only on the lead unit.
Check that each humidifier has a unique modbus address.
BMS Network Connection:
Lead unit wired to BMS system (Twisted Pair or Ethernet).
Network activity verified.
Shields should be connected at BMS end only.
Controls Wired:
Directly to humidifiers or through BMS network.
Ensure power is being supplied to the humidifier, NORTEC Links Module. For BACnet/IP adjust network IP settings. (If this information is provided, factory will perform necessary IP assignment).
After power-up, verify network communication.
Map desired network variables to BMS.
Verify variable operation after mapping is complete.
Perform regular humidifier start-up check.

Troubleshooting
When troubleshooting the communication process for Links XPS modules should be kept in mind. Humidifier data is received by the NORTEC Links module using the modbus rtu protocol over the serial port connection. The Links module then translates the data to the desired protocol for connection over the networks.
Indicator Lights
There is a variety of status LEDs on the Links XPS module to aid in the diagnosis of communication problems. Please refer to the following figures for locations and meaning

Problem
Solution
The BMS network cannot read/write any information to any of the networked humidifiers
Verify that the network connection is made and is connected properly.
Verify that the correct network settings are being used. The Links XPS module may need to be restarted to load the new settings.
Check the Serial Port Activity LED on the Nortec Links module to ensure proper communication from the humidifiers to the Links XPS module.
Check the Ethernet port activity on the Links XPS module to ensure it is receiving data.
Check the transmit and receive status LEDs to determine if there is any network traffic being sent or being received by the Links XPS module from the BMS network
Verify proper connections to networked humidifiers.
Turn the Links XPS module off for several seconds then switch it back on to reload the control program. Allow for some time for the network variables to be polled.
The BMS network can see some of the networked humidifiers but not others.
Ensure network variables are mapped correctly to the BMS.
Ensure proper connections to the humidifiers.
Disconnect all of the humidifiers from the Links XPS package except for the unit that is not responding to the network. Turn the Links XPS package off and then back on. Check if the humidifier can now be seen by the BMS
The BMS network receives information from the networked humidifier(s) but the information is mismatched or the humidifier responds un-expectedly
Verify that the network variables have been mapped to the BMS network correctly. It is possible that the variables have been cross-linked during the network integration process.
Connect humidifiers one at a time and test units individually.
After sending the humidifier a network­based demand signal the unit powers down after several minutes. The nviNetSensor variable is switched on and a value has been set for the nviRHDem1 variable.
When a BMS network demand/RH signal is being used the network must refresh the nviRHDem signal at least every 5 minutes otherwise the humidifier will revert to a 0 demand state. This is a safety precaution in case the BMS network connection is lost.
