System 9100 Technical Manual 636.4 XTM/XPx Section Technical Bulletin Issue Date 0309
The XTM-105 Extension Module and XPx-xxx Expansion Modules combine the functions of relays, signal conditioners, and overrides for controlling building operations (Figure 1). The XTM-105 module provides the communications interface and the XP modules provide the analog, binary, and multistate inputs and outputs. Incremental point additions with up to 40 input/output points per N2 connection are allowed.
The supervisory system communicates with the XTM-105 via the N2 Bus. The XTM-105 can be configured using a Personal Computer (PC) with the XTM Configurator software or by downloading a previously defined configuration. When the XTM-105 is powered up, it automatically reads which XPx modules are connected and compares this data with the I/O Type Map. For details on the XTM Configurator software, refer to the XTM Configurator Technical Bulletin (Code No. LIT-6364220). Magnetic and electric latching relays are available to assure proper restart conditions in the event of power failure. Many models include manual override for temporary on-site adjustments. Light-Emitting Diodes (LEDs) show the command status of the points.
Note: The XTM-105/XPx-xxx requires Metasys® Release 8.0 or later software and Companion™ Release 6.02 or later software.
Figure 1: XTM-105 Extension Module and XPx-xxx Expansion Modules
The extension modules are designed for installation on standard DIN rails within a control cabinet. The outer dimensions of the modules also conform to DIN standards for small, wall mounting enclosures. Figure 2 shows the XTM/XPx-xxx mounted in the Universal Packaging Module (UPM). For details, refer to Accessories in Appendix C: Ordering Information in this document.

The XTM-105/XPx-xxx offer the following features:
• 4 to 40 input/output points. (The 40 point maximum is reached by using 1 XPA-821 and 4 XPE-404s (or XPT-401s), for a total of 8 analog inputs/outputs, 16 binary inputs, and 16 binary outputs.)
• analog inputs 0-10V, 0/4-20 mA, RTD (Pt1000, Ni1000, A99)
• binary inputs with LED indicators
• binary triac outputs (24 VAC) with LED indicators (supports manual override on XPT-401)
The extension modules are ideal for distributed monitoring and control. Their design enables high density installation in large control cabinets and requires no extra terminal blocks for field wiring. Figures 3 and 4 show two possible applications.
For detailed configuration requirements for a particular supervisory system, refer to the technical documentation for that system.
Notes: XTM-105 modules cannot reside on the XT Bus of the DX-9100/DX-9120 controller. For information on DX-9100/DX-9120 compatible modules, refer to the XT-9100 Technical Bulletin (Code No. LIT-6364040) located in the System 9100 Technical Manual, FAN 636.4.
The XTM-105 can be connected to a remote N2 Dialer Module (NDM) trunk only if dial-in control on the remote NDM is disabled. For details, refer to the Disabling Dial-In section of the N2 Dial Application Application Note (Code No. LIT-6375150) located under the N2 Dial tab in the HVAC PRO for Windows User’s Manual (FAN 637.5).
IMPORTANT: The XTM/XPx-xxx comply with U.S. standards for radiated and conducted emissions per the Federal Communications Commission (FCC) CFR 47, Part 15. They also comply with the European Community (CE) Electromechanical Compatibility (EMC) Directive 89/336/EEC for residential and industrial environments. However, lack of attention to generally accepted control wiring installation practices may lead to controller problems in electromagnetic field environments, which exceed the limits of these standards. For details, refer to the N2 Communications Bus Technical Bulletin Code No. LIT-636018 located in the Metasys Network Technical Manual (FAN 636) under the Component Data Sheets major tab and Network Communications minor tab.
The power watchdog circuit of the XTM-105 verifies that power is getting to all XPx-xxx modules.
State 0 is the Off stage or state.
Supervisory system refers to any system that communicates with the XTM-105 over the N2 Bus.
Wired 0 provides positive feedback to confirm that the monitored equipment is in its Off (0) state, rather than assuming that it is Off when it is in none of its On states. Feedback is accomplished through the use of an additional hardware binary input device.
The XTM-105 extension module requires 24 VAC power. Use the appropriate transformer (sold separately) per agency listing. For details on ordering transformers, refer to Accessories in Appendix C: Ordering Information. Refer to Appendix A: Technical Data for details on electrical requirements, power consumption, terminations, etc.

Each expansion module position contains either one XPx-8xx type module or a pair of XPx-4xx type modules. If XPx-4xxs are installed in any position, then the half positions are referred to as XPxA and XPxB (e.g., the two XPx-4xx positions in XP1 are called XP1A and XP1B).
Each point in an expansion module has a label to identify the LEDs and manual override switches (Table 2). The point labels are the same for any type of module so the same point label may appear more than once per configuration.

LEDs (All Modules) Manual Override SwitchesXPA-821 6 analog inputs
When configuring binary inputs as feedback points for binary outputs on XPL, XPE, and XPT modules, use inputs and outputs with the same numeric reference in the tag. For example:
Output: 1DO1 Feedback: 1DI1
Output: 2DO5 Feedback: 2DI5
For details, refer to Feedback Assignments under the Binary Output and Multistate Modules section of this document.
Table 4 contains information about the XPA-821 analog expansion module.
Table 4: Analog Expansion Module XPA-821 Model Analog Inputs Types Analog Outputs Types XPA-821-5 6 analog inputs

2 analog outputs (AO7-AO8) (without manual override)
0-10 VDC 0/4-20 mA
By jumper configuration, the XPA-821 expansion module with analog inputs accepts (Figure 25):
• 0-10V, 0-20 mA
• passive Resistance Temperature Device (RTD) sensors
The measurement unit of each RTD input is configurable for degrees Celsius or degrees Fahrenheit. For details on RTD sensor measurement ranges, refer to Table 5. Select the type of input (voltage, current, resistance) using the XPA-821 jumpers.
Table 5: RTD Sensor Measurement Ranges Module RTD Sensor Range XPA-821 Ni 1000 Regular Sensor (JCI) -45 to +121°C / -50 to +250°F Ni 1000 High Temperature Sensor (JCI) +21 to +288°C / +70 to +550°F Platinum 1000 (DIN) Sensor -50 to +200°C / -58 to +392°F A99 Sensor (JCI) -50 to +100°C / -58 to +212°F
The XPA-821 provides the 15 VDC supply for the analog input sensors. The maximum current supplied from this power supply is 30 mA.
A high and low alarm limit setting with alarm limit differential can be assigned to each of the analog inputs.
Select the type of output (voltage or current) using the XPA-821 jumpers (Figure 25). The output signal is proportional to the requested analog output value from 0 to 100%.
Binary inputs are powered from the XTM-105 module by a standard 24 VAC power. By software configuration, the input is active (set) when it is:
• connected to the binary input common via an external potential-free contact (normally open), or
• disconnected from the common via an external potential-free contact (normally closed).
LEDs indicate the status of each input on the binary expansion module. The red LED lights when the corresponding input is active.
A binary input may be defined as maintained or pulse type. With maintained type contacts, the status reported by the XTM-105 follows the status of the contact. With pulse type contacts, the XTM-105 sets and resets the status at each pulse of the input contact. Pulse types are only recommended for manual override functions, such as lighting control, where the user gets confirmation of the override request by a verifiable response. This is because the pulse type input toggles the binary input and without some form of feedback it is not possible to count the pulses to verify the binary state.
If no analog modules are installed in position XP0, the counter function is available for a binary module. A single 8-input, a single 4-input, or two 4-input modules may be configured as counter modules. The number of input contact transitions required to increment the counter on each input is set through software configuration to the XTM-105 module.
The counter values are stored in 4-byte memory locations in Random Access Memory (RAM). On power failure, the values are automatically saved in Electrically Erasable Programmable Read-only Memory (EEPROM) and then restored to RAM when power returns. The maximum pulse frequency at the input is 25 Hz. The minimum pulse width is 20 ms for On time and 20 ms for Off time. The counters are configurable to roll over at the maximum 4-byte value or at the specific decimal values of (9,999), (999,999), or (9,999,999).
The supervisory system must be programmed to command the appropriate binary output by its tag name.
The binary outputs have a specific Item tag name (e.g., xDO1-xDO8) and are configured as On/Off or pulse outputs. The contact or triac of an On/Off binary output closes or opens on command and remains in the commanded state. The contact or triac opens if the module loses 24 VAC power.
The contact or triac of a pulse binary output closes momentarily on each command (On or Off). The length of the pulse is determined by configuration (default is 20 ms).
The contact for the binary output or for Stages 1, 2, and 3 closes or opens on command and remains in the commanded state by electrically latching the contacts. The contacts are interlocked so only one output is active at a time. Stage 1 has the highest priority. State 0 is active when no other stage is active. Electrically latched contacts open if the module loses 24 VAC power.
The contact for the binary output or for Stages 1, 2, and 3 closes or opens on command and remains in the commanded state by a magnetic latch on the relay. The contacts are interlocked so only one output is active at a time. Stage 1 has the highest priority. State 0 is active when no other stage is active. The magnetically latched contacts do not change state on 24 VAC power loss.
Binary outputs use consecutive binary output references (Table 6).

The individual binary outputs associated with binary multistate output modules do not have to be configured because the modules always drive the output relays as magnetically latched (XPL) or electrically latched (XPE), according to the type of module. The only exceptions are the XPE-404 modules.
One normally open relay contact is provided for each output stage.
Binary Output and Multistate Modules
Relays (XPE-404 Modules) and Triac Outputs (XPT-401 and XPT-861)
The binary inputs of all XPE/L binary output and multistate modules as well as the XPT-401 are normally used as feedback indicators for the outputs of the same module. To use an additional binary input as feedback for State 0, wire both the Normally Open (NO) and Normally Closed (NC) on a Single-Pole, Double-Throw (SPDT) switch (Figure 6). This provides positive feedback that the controlled equipment is Off.

* With wired 0, the binary output xDO2 (xDO6) in a binary module serves only as an output without feedback. If possible, use a binary input other than xDI2 (xDI6) as feedback. In other words, when xDO1 (xDO5) has binary feedback with wired 0, the binary input used for the On state is xDI1 (xDI5) and the binary input used for the Off state (wired 0) is the xDI2 (xDI6). Therefore, xDI2 (xD16) is not available for the feedback for xDO2 (xDO6).
* When wired 0 is used with xDO1 or xDO5 on a 2-stage module, the remaining binary output xDO3 or xDO7 has no corresponding input available for feedback. Either configure the binary output without feedback or use a different binary input for feedback (other than xDI3 or xDI7).
The binary output and multistate modules with manual override have two to four switches (depending on the number and type of outputs) on the right side of their front panels. The switches on the XPE/L modules have two or three positions and latch in each position (up, middle, down).
For instance, a binary output on an XPE/L module has an associated switch with positions labeled A, 0, and 1 (bottom switch in Figure 7).
Table 10: XPE/L BO Switch Positions for Single Stage Output Position Function A Sets the output to Automatic mode for supervisory system control. 0 and 1 Enables Manual Override mode and sets the output to the selected
state.
Notes: By software configuration, the manual override operation for binary output modules may be disabled when the module is connected to an active supervisory system. In this case, the manual override operation is only enabled when the supervisory system communication fails and the module is in a Standalone mode. For details, refer to the XTM Configurator Technical Bulletin (Code No. LIT-6364220).
The LEDs are configurable to show the output state set during manual override operation or the last commanded state from the supervisory system. The LED default condition shows the last state commanded from the supervisory system.
A 2- or 3-stage output on an XPE/L module has two switches, where the first switch (top switch in Figure 7) has positions labeled A, 0, and M, and the second switch (middle switch in Figure 7) has positions labeled 1, 2, and 3 (3 for the 3-stage output).
Table 11: XPE/L Switch Positions for 2-3-Stage Output Position Function A Sets the output to Automatic mode for supervisory system control.
0 Sets State 0 and the second switch has no function.
M Sets Stage 1,2, or 3 depending on the second switch.
To set the output to a stage other than 0 in Manual mode:
1. Set the first switch to M.
2. Set the second switch to the output to Stage 1, 2, or 3.
The XTM-105 extension module requires 24 VAC power. Use the appropriate transformer (sold separately) per agency listing. For details on ordering transformers, refer to Accessories in Appendix C: Ordering Information. All modules are suitable for 50 Hz or 60 Hz.
The XTM-105, XPA-821, and XPB-821 require proper jumpers and Dual Inline Package (DIP) switch settings prior to supplying power to the modules. Refer to Commissioning and Troubleshooting later in this document for details.
! WARNING: Shock hazard. Before servicing, disconnect connections to the terminals of XPL and XPE expansion modules. These carry up to 250 VAC or 250 Volts Direct Current (VDC).
! CAUTION: Equipment damage hazard. When handling these modules take necessary precautions because circuits are sensitive to static electricity.
Follow the guidelines below:
• Do not mount the modules in heavy-duty switch gear cabinets or in cabinets with frequency-converting or phase-cutting equipment.
• Physically separate low voltage wiring in electrical cabinets from line voltage and power wiring (Figure 10).
Το avoid electrical interference in field cables:
• keep input and output point cable runs as short as possible [< 164 ft (50 m)]
• use twisted pair cables
• run low voltage cables non-parallel to power cables for long distances [> 9.84 ft (3m)]
• separate cables from transformers and high frequency generating equipment
• use a cable recommended for RS-485 transmission (N2 Bus)
Figure 8 shows the dimensions of the XTM-105 module. When mounted on a DIN rail, the modules can be placed side by side so the overall width of the unit is just the sum of the widths of the individual modules.

IMPORTANT: For UL 916 energy management applications line voltage, low voltage, and power limited wires must be separated (Figure 10). Special segregation issues apply when a module supports both power limited and non-power limited wiring. Each side of the module must contain either power limited or non-power limited wiring (not both). Further, power limited wiring must not overlap non-power limited wiring within the enclosure. For example, when wiring an XPL-401-5 with a power limited circuit and a non-power limited circuit, use two separate XPL-401s: one for power limited field connections and the other for non-power limited connections (Figure 10).
Modules are shipped with a label stating “Power Limited Field Terminal.” When configuring a module’s input and/or output for non-power limited field connections, cover the wording on the label with permanent black marking pen. Only modules that are totally dedicated to power limited field wiring should display this label.

Terminations are made via the terminal blocks on the upper and lower parts of the modules. Refer to Appendix A: Technical Data for details on terminations electrical requirements, power consumption, etc. Also see Wiring Examples later in this document.
Note: The XTM-105/XPx-xxx comply with U.S. standards for radiated and conducted emissions per the FCC CFR 47, Part 15. They also comply with the CE EMC directive 89/336/EEC for residential and industrial environments. However, lack of attention to generally accepted control wiring installation practices may lead to controller problems in electromagnetic field environments that exceed the limits of these standards. For details, refer to the N2 Communications Bus Technical Bulletin Code No. LIT-636018 located in the Metasys Network Technical Manual (FAN 636) under the Component Data Sheets major tab and Network Communications minor tab.
When connecting the N2 Bus cable to the terminals provided on the XTM-105, adhere to the following guidelines:
• 3937 feet (1200m) maximum bus length.
• When the XTM-105 is the last item on the N2 Bus, use a 220 ohm End-of-Line (EOL) resistor to terminate the end of the bus (Figure 11).
• When the bus length is greater than 328 feet (100m), terminate both ends of the N2 Bus with 220 ohm EOL resistors.
• If the bus length is less than 328 feet (100m), terminate only at the controller with a 220 ohm EOL resistor.

Expansion modules are connected to the XTM-105 and to each other with two 5-pin ribbon cables, which are supplied with the expansion modules. One ribbon cable plugs into the connectors at the top of adjacent modules to enable communications and it supplies the 5 VDC Bus from the XTM-105 to each module. The second ribbon cable plugs into the connectors at the bottom of the modules to provide 24 VAC and power from the XTM-105 to each module.
Note: For the power watchdog circuit to operate properly, only the last expansion module connected to an XTM-105 must have the loopback (end of bus) jumper installed in the correct position on its connector for the 24 VAC module supply bus (Figure 12). When the power watchdog is not operating properly, the XTM-105 Power LED flashes at a frequency of approximately twice per second.

3-speed Fan Control Figure 13 illustrates a multistage output module (XPE/L-403) used to control a 3-speed fan. The output is a set of interlocked relay contacts. There is one contact (Terminals I, II, III) for each speed, and the contact closes when that speed is selected to run. Terminal BO is provided to connect the fan supply voltage to the controller to facilitate the wiring to the fan motor. The line voltage is used only to power the fan.

1. Set a unique extension module address on the XTM-105 using the address switches at the bottom of the module.
2. Set the types of analog inputs and outputs for the XPA-821 using the jumpers on the module circuit board.
All settings must comply with the software configuration. For modules other than the XTM-105 and XPA-821, no hardware settings are necessary because all configuration is handled by the software.
Set a unique XTM-105 module N2 address (for the supervisory system) using the block of eight DIP switches next to the lower terminals on the XTM-105 module.

Figure 23: Address Switch on the XTM-105 (Address = 10)
The switches are numbered 1 to 8, each representing one bit in an 8-bit binary representation of the address with an address range of 0-255. Binary representation means that setting a switch to On adds (to the address) a specific decimal amount corresponding to the position of the switch. The switch numbers and the decimal amount each switch represents are:
Switch Number 1 2 3 4 5 6 7 8
Decimal Amount 1 2 4 8 16 32 64 128
To set a decimal address of 119, for example, set Switches 1, 2, 3, 5, 6, and 7 to On (1 + 2 + 4 + 16 + 32 + 64 = 119) as shown in Figure 24.
To set the AIT for each of AI1 to AI6 (labeled JP1 to JP6 on the circuit board, and 1 to 6 in Figure 25):
1. Use one jumper per input in each respective position numbered 1 to 6 on the corresponding jumper block.
2. Place a jumper on the upper two pins to set an RTD resistive sensor input.
3. Place a jumper on the lower two pins to set a 0-20 mA current input.
4. Remove the jumper completely to set a 0-10V input.
A maximum of 30 mA is available from the 15V supply of the module.
Analog Output Type (AOT)
Set the AOT for each of AO7 and AO8 (labeled JP7 and JP8 on the circuit board, and 7 to 8 in Figure 25) on the corresponding jumper block. Two jumpers are required for a 0-20 mA output and one jumper for a 0-10V output.
Inspect the field wiring, switch and jumper settings, and the N2 Bus cabling before applying power to the XTM-105. If the software configuration has not been downloaded to the XTM-105, refer to the XTM Configurator Technical Bulletin (Code No. LIT-6364220).
At power up, the XTM-105 compares the software defined configuration with the number and types of expansion modules connected to the XTM-105. If the configurations do not match, the XTM-105 Power LED blinks continuously, indicating an error.
There are three LEDs on the front of the XTM-105 module: Power (PWR), Receive Data (RD), and Transmit Data (TD). The RD LED lights when data is on the N2 Bus. The TD LED lights when the XTM-105 is responding on the N2 Bus.
When powered up, the Power LEDs on the XTM-105 indicate the conditions outlined in Table 13:
Table 13: XTM-105 Condition and Power LED Indication Condition Power LED Indication Good communications with the supervisory system over the serial link (N2 Bus). No configuration errors.
Continuously lit.
No communication with the supervisory system.
Flashes at a frequency of approximately once per second.
Configuration error or power watchdog error.
Flashes at a frequency of approximately twice per second.
If there is a communications fault, check the N2 Bus cabling and EOL termination as well as the address setting on the XTM-105. The address setting must be unique and agree with the address set on the supervisory system.
If there is a configuration error verify that:
1. The software configuration agrees with the actual types and number of expansion modules connected to the XTM-105.
2. The ribbon cable connecting the expansion module communications bus is properly seated.
3. The power watchdog jumper is installed (Figure 12).
All modules are equipped with a protective device that limits the current drawn from the 24 VAC supply to approximately 500 mA. An internal failure or an external short circuit may occur as a result of incorrect wiring to the binary input terminals, which have the same “common” as the 24 VAC supply. If a module is not working (no LEDs light when the input or output is active), check the wiring. If the wiring is correct, replace the module.
The performance specifications are nominal and conform to accepted industry standards. For applications at conditions beyond these specifications, consult the local Johnson Controls office. Johnson Controls shall not be liable for damages resulting from misapplication or misuse of its products. The specifications in Table 14 apply to all modules.

Notes: The analog high/low limits and differentials can be written from a supervisory system.
IF E( ) Item stored in EEPROM. Exceeding the maximum 10,000 write commands causes permanent damage to the XPA. Avoid mapping these points in a continuous process that changes their values at timed increments. Perform manual commands or monitoring only. The supervisory system writes new limits whenever the XTM/XPA comes online or when the AI point is added or modified from the supervisory system.

Johnson Controls offers versions of the XTM-105/XPx-xxx that meet various market specifications (Table 32). The modules offered in North and South America (Table 30) are a subset of those available in other markets and all have been tested for UL, CSA, and FCC agency listings. If you need a module not listed in Table 30 of Appendix C: Ordering Information, have your local Johnson Controls representative contact the product development team in Milwaukee. If there is sufficient demand, additional models may be made available for your market.
The disconnect terminals are a requirement in the German market. They allow the electrician to wire the modules without having the wire electrically connected to the module. Each terminal has a blade switch that is permanently connected to the module (Figure 39). The only difference between the modules with disconnect terminals and those without is the extra height of the body, which is needed to accommodate the larger disconnect terminal blocks. The characteristics and specifications of the two types of modules are otherwise identical.
