Description

Specifications

The T-Line is part of the I/O Hardware family of control modules and is designed specifically for zone control. The T-Line consists of the T320, T320v, T540, and T540v ("v" indicates the board has a flow sensor). A single main board provides the power circuitry, the microprocessor, and nonvolatile memory. The name of the module indicates the number of outputs and inputs which it provides. The T-Line modules are designed to be mounted directly on the equipment being controlled, such as VAV boxes, heat pumps, unit ventilators, and fan coil units.

Each T-Line module communicates with the CMnet through a Tnet Interface module (TNI) (see Figure 6). Each T-Line module can store an optional default algorithm (see T-Line Default Algorithm Downloader TI for more information) which maintains the space temperature in the event that communications is lost with the TNI module.

Each T-Line module is associated with a single T-Line Graphic Function Block (GFB) downloaded into the TNI module. Sample T-Line GFBs are available from the BBS which can be used as a starting point for customizing the GFBs for your specific application. However, before customized FBs can be downloaded, they must be made in Eikon according to the Zone GFBs standards. The small percentage of Zone GFBs which can not be made in Eikon can be reviewed and encrypted by Dealer Services.

NOTE: To operate this module based on a schedule, it must be networked with a Gateway module.

Power: 24 VAC ±10%, 50-60 Hz, 2.4 VA (0.10A) maximum.

Inputs: T320/T320v - (2) Dry contact or thermistor. T540/T540v - (4) Dry contact or thermistor, two of which can be configured as 0-5 VDC. Custom translation tables allow nonstandard signals. If used, the RSZ+ requires 2 inputs.

Outputs: (T320,T320v = 3; T540, T540v = 5): Digital outputs, rated 1 Amp @ 24 VAC. See Figure 2 for allowable configuration.

Flow Sensor: (T320v, T540v only) Range of 0-2" w.c.,

0.003" wc resolution.

Status Indicator: LED indicators for visual status of receive, transmit/run, and each output.

Communications: EIA-485 port for communicating on the Tnet.

Memory (T-Line): Non-volatile storage of default control algorithm.

Memory (TNI): 128k bytes of non-volatile storage divided into 8 banks of 16k per module (virtual and real).

Protection: Bussed output relays to eliminate phasing problems, surge protection on network lines and on input power, arc suppression on relays. (Use the Optional T-net Protection Board (TNPB) which is available for additional network surge protection.)

Limitations

1. No pulse accumulation inputs are allowed on T-Line FBs, except for the TLO button reserved for the enhanced zone sensor (RSZ+).

2. The TLO button on the RSZ+ can only be connected to Universal Input #2 on the T-Line's enhanced zone sensor port (pin 3).

Trending

Using virtual modules to increase the number of FBs in the TNI decreases the memory available for trending. If all 40 FBs are used, only a very limited number of points can be trended. No enhanced trending capabilities are available.

3. For T540 and T540V, digital output 5 can only be used for start/stop control.

4. Digital outputs 1 and 2 can only be used for VAV Flow Control on the T540v and T320v.

Figure 2 lists the possible output configurations of the T-Line modules.

T-Line Modules Not For Time Critical Applications

T-Line modules have been designed to meet low-end, high-volume terminal control applications. As a result, time-critical applications (such as short time delays and trend intervals of less than one minute) should not be used with these modules. ALC recommends that all time delay functions and trend intervals on T-Line FBs be set to greater than or equal to 1 minute.

No pulse accumulation inputs are allowed on T-Line FBs, except for the TLO button reserved for the ALC enhanced zone sensor (RSZ+).

T-Line Mounting

NOTE: Before mounting any T-Line board, make note of the board's I.D. number. The board I.D. number can be found on the large 28 pin integrated circuit (I.C.) (see Figure 5).

1. Remove the T-Line board from the Snap-Track.

2. Position the Snap-Track in a convenient location, providing at least 1½" clearance on each side for wiring purposes. Mount by using self-drilling screws and drill directly into the plastic near the edges of the Snap-Track so that the screws will be visible when the T-Line board is installed (see Figure 3). This prevents loose screws from shorting out the back of the T-Line Board.

3. Mount the T-Line board on the Snap-Track by pushing it firmly into the grooves.

Addressing

T-Line modules are not addressed by dip switches; instead they are programmed with an I.D. number at the factory. The board I.D. number can be found on the large 28 pin I.C. Enter this number on the parameter page of the TNI Function Block (FB #15). See Parameter Page on page 24.

Virtual Modules

NOTE: The use of virtual modules decreases the memory available for trending.

use the maximum of 40 GFBs per TNI, the TNI will use the real module and at least three virtual modules to store GFBs.

In some cases, a module (real or virtual) will not support 10 GFBs due to the size of the GFBs. For those cases, it is necessary to add one or more virtual modules and distribute the GFBs among them. For example, a TNI may contain 8 modules (1 real and 7 virtual), each containing 5 GFBs (8 x 5 = 40). Some room should be left in the physical module's memory for enhancement and features to be added to the module driver. See the section "Adding T-Line Modules" for more information on hardware and software procedures.

As shown in Figure 4, a TNI has the capability of acting as one real module and seven virtual modules. This allows one TNI to have a total of eight addresses either in sequence or not. Each module (real or virtual) contains 16k bytes of memory. Virtual modules are addressed on the module driver (FB #15) parameter page. The virtual module addresses do not have to be contiguous if the TNI exec is 4.07 or higher. The TNI itself (real module) is physically addressed using the hardware dip switches.

TNI modules allow for the use of virtual modules in order to increase the maximum number of GFB's that may exist in each TNI (see Figure 4). Each TNI virtual module is an addressable node on the CMnet that may contain up to 10 GFBs (if memory allows) and one module driver (FB #15) as long as the maximum of 40 GFBs per TNI module (including virtual modules) is not exceeded. To

CMnet - Maximum 700 GFBs

address = 10

The CMnet can support up to 100 control modules (1 FB each) and 700 GFBs (not including module drivers) for a total of 800 FBs.

Default Algorithm Downloader

NOTE: For more information, please reference the T-Line Default Algorithm Downloader TI (part no. TITDAD).

Each T-Line module has the capability of storing a default algorithm which maintains the space temperature in the event that communications are lost with the TNI module.

NOTE: Each T-Line FB uses channel 27 to indicate whether communications are good (DI=ON) or bad (DI=OFF).

Figure 6: Tnet Architecture

The T-Line Default Algorithm Downloader is a communications program which enables you to download default algorithms from your computer directly to the T-Line modules. The computer connects with the T-Line modules through an Opto Repeater or Tnet Adapter. Refer to the T-Line Default Algorithm Downloader Technical Instructions for more details.

Power and Communication Wiring

1. Connect the 24 VAC power wires to a single T-Line

module as described in the following steps.

a. Terminate AC power at the wiring source

(usually a circuit breaker or other AC source).

b. Terminate power to the high voltage side of the

transformer.

c. Remove the T-Line's power jumper (see Figure

5). This prevents the module from being powered up until proper voltage is verified.

Important Notice

Avoid damaging the T-Line modules communication circuits.

• IF you have multiple T-Line modules powered

by the same transformer,

• IF you have multiple T-Line modules powered

by separate transformers, but have their grounds connected (either through wires or through conduit),

THEN you must observe the same polarity on the T-Line modules’ AC-power connections.

CAUTION: The T-Line modules are Class 2 devices (less than 30 VAC). Take appropriate isolation measures when mounting a T-Line module in a control panel where Class 1 devices or wiring are present.

NOTE: If wiring the T-modules together in a bus power

configuration (several T-modules sharing a single transformer as shown in Figure 8), care must be taken in the wiring and transformer sizing. The average current value for a T-module is 100 mA (0.1 Amps), but the peak current value for a T-540v with all outputs on is 670 mA. Therefore, the wire and transformer must be sized larger than apparent from the averaged value of the module VA rating. See Figure 7 on calculating wire and transformer requirements for a bus power configuration.

NOTE: To protect the Tnet communication wires, ALC highly recommends installing TNPBs at the beginning and end of each Tnet leg as shown in Figure

d. Terminate the two power wires to the 24 VDC

and GND terminals indicated in Figure 5. Note the polarity. See "Using Quick Disconnects" later in this document for guidelines.

e. Verify that 24 VAC is present at the power input

and replace the power jumper.

2. Connect the Tnet communication wires to the same T-Line module as described in the following steps.

a. Remove the module's power jumper. b. Check the Tnet communication wiring for shorts

and grounds.

c. Terminate the Tnet communication wires to the

Tnet screw terminals indicated in Figure 5.

Note the polarity of the Tnet wires coming from the TNPB.

d. Replace the module's power jumper.

3. Go to the next T-Line module on the Tnet and connect the AC power wires as in step 1, using the same polarity as on the first T-Line module. Do not connect the communication wires yet.

4. To check for proper power polarity, measure the AC voltage between one of the communication wires and one of the communication terminals. If the AC voltage is greater than 5 VAC, reverse the T-Line module’s power wires and remeasure.

• If the voltage is still greater than 5 VAC, then

check for one of the improper wiring configurations on page 12. Rewire the T-Line modules according to one of the figures on page 10 and remeasure.

NOTE: Whenever possible, terminate and verify power and communications to all modules before terminating any inputs or outputs.

BEFORE wiring power or communications to any T-Line modules on the Tnet, use the following procedure.

To avoid excessive voltage drops, use the following formula (copper wire):

Wire Resistance =

(# of T-modules) * (max. peak current)

5 V drop allowed

Example: Six T540v modules

1.24 Ohms =

5 Volts

6 * 0.670 A

The above formula and resulting values in feet are conservative and do not take into account the decreased current as the wire pair extends past each module.

From the above Formula: The total resistance allowed when wiring six T540v modules = 1.24 ohms

From the Wire Table: 12 AWG wire has a resistance of 1.588 ohms per 1000 feet.

1.588 Ohms 1000 ft

1.24 Ohms X

1.588 X = 1240 => X = 780.85 ft.

Thus, you can use a total of 780 ft. of 12 AWG wire to connect the six T540v modules. This means that you can run a pair of wires to the modules a distance of 390 ft., after that distance you will need to add another transformer.

The sizing of the transformer should be adjusted to compensate for the non-sinusoidal waveshape of the current requirements. The VA rating of the T-module should be multiplied by three (3) when computing multiple T-modules being supplied by one transformer.

Example: Six T540 modules (6 modules) ∗ (2.4 VA per module ∗ 3) = 43 VA

T-modules are used on a T-net, then an Opto Repeater (part no. REPOPT) must be inserted into the T-net after the first 20 modules (see Fig. 6). A maximum of 40 modules may be on a T-net with the use of an Opto Repeater.

Zone Sensor Wiring

CAUTION: Because the standard zone sensor inputs are not surge protected, they should only be used for thermistors or the enhanced zone sensor. Any other use could result in damage to the hardware.

Adding T-Line Modules

Hardware Procedure

1. Add the new T-Line module(s) to the existing T-net (see the section "Power and Communications Wiring" for more details).

2. Enter the I.D. number for the new module on the parameter page of the TNI module driver (FB #15). Refer to the section on Addressing for more information.

3. Use one of the two methods described below to make the TNI recognize the new T-Line module(s). Either method is sufficient.

Software Method -- Zap the TNI as follows:

a. Go to the Modstat page for the TNI. b. Press [Esc] to get a pop-up menu. c. Type in ZAP.

Hardware Method -- Turn the TNI module's power off then back on.

Standard Zone Sensor (Using the Enhanced Zone Sensor Port)

1. Remove the module's power jumper.

2. For input 1 (UI 1), connect the zone sensor wires to pins 1 and 2 on the 8-pin receptacle on the T-Line module (see Figure 17).

3. Replace the power jumper.

4. Input the channel number, offset, and gain on the

Figure 17: Standard Zone Sensor connections

Software Procedure

1. Run FBfit to determine if the new T-Line FB will fit

with the other T-Line FBs into an existing real or virtual module (16 kB).

2. If it fits, add the FB to config.txt, compile, and download memory to the real or virtual TNI modules to which the FB is being added.

3. If it doesn't fit, add a new virtual module and the FB to config.txt, enter the new virtual module address on the real TNI module driver parameter page, and download parameters to the real TNI and download memory to the new virtual module (see the section "Downloading Memory" for more details).

Rev. (29-JUN-99) • TNI v4.7

T-Line zone FB parameter page (UI 1 uses channel number 31 and UI 2 uses channel number 32).

5. If using input 2 (UI 2) on the Enhanced Zone Sensor Port, repeat steps 1-4, connecting the sensor between pins 1 and 3 on the 8-pin connector on the T-Line module see Figure 17.

NOTE: When making a sensor cable, disregard the numbers imprinted on the plastic connector.

Enhanced Zone Sensor

1. Remove the module's power jumper.

2. Plug the Amp 8-pin connector to the 8-pin receptacle. If you are constructing your own cable, use the crimper shown in Figure 20. Refer to Figure 18 for the cable wiring configuration. Use 22 AWG wire.

Shown in Figure 19, the enhanced zone sensor provides local setpoint adjust, timed local override, and occupancy indication.

Local Setpoint Adjust

Use the sensor's left switch to adjust the occupied setpoints. When this switch is placed in the middle position, the setpoints specified on the T-Line FB parameter page are in effect. The switch's left position lowers the setpoints by an amount specified on the parameter page (default is 3 degrees). The switch's right position raises the setpoints by the same amount.

Timed Local Override

Use the sensor's right switch to activate the zone override. The switch is spring loaded and always returns to the right position. This switch has no effect when the zone is scheduled occupied. When the zone is scheduled unoccupied, toggling the switch causes the zone to become occupied. The amount of override time is equal to the number of times the override switch is toggled multiplied by the "override increment per toggle" parameter as defined on the parameter page. For example, if the increment is set at 60, toggle the switch once for an occupancy of 60 minutes, twice for 120 minutes, etc. Once the zone is occupied from this switch, pressing it again and holding it in the left position for the reset interval (three seconds default) causes the zone to become unoccupied.

Occupancy Indication

The LED on top of the sensor lights up whenever the zone is occupied, whether from a regular schedule, the action of the Local Override Switch, or a telephone override.

NOTE: Pins 4 and 7 must be connected to utilize the occupancy indicator.

ALC part no. CON is a package of 8-wire connectors and covers (AMP part nos. 641237-8 and 640550-8) which require 22 AWG standard wire. Other connectors are available by calling your local AMP distributor at 800526-5142. The cable wiring configuration is show in Figure 18. The cable should not exceed 50 ft.

NOTE: When making a sensor cable disregard the numbers imprinted on the plastic connector.

Procedure

Local Access (Optional)

The T-Line modules are not equipped with direct access ports. This means that troubleshooting the modules can be difficult for one person since the controlling TNI may not be located near the T-Line module undergoing maintenance. Using this procedure, it is possible to

Rev. (29-JUN-99) • TNI v4.7

1. Pull CMnet cable to each T-Line module at the same time the Tnet communications cable is run (see Figure 21).

NOTE: It is very important to isolate the CMnet cable from the T-Line modules with an Opto Repeater at the TNI (see Figure 21). Otherwise a shorted sensor could crash the entire CMnet.

2. Check the CMnet wires for shorts and grounds.

3. Remove the module's power jumper.

4. Terminate the CMnet wires to the yellow and green wires of the sensor cable (pins 5 and 6) at the T-Line module as shown in Figure 22. Observe the proper polarity.

5. Insert the module's power jumper. The CMnet may now be accessed at the Enhanced Zone Sensor using its Remote Terminal Connector port.

NOTE: This method bypasses the priority arbitration provided by the gateway module (GCM2 or the LANgate). To avoid potential communication errors, make sure that no one attempts to communicate with the system at the same time this method is used.

Input Wiring

The T-Line's inputs may accept dry contact, thermistor, or 0-5 VDC signals (see Figure 23 for jumper settings). For non-standard inputs, refer to section "Custom Translation Tables."

One input is dedicated to measuring space temperature. A second input is used for either the Enhanced Zone sensor's local setpoint adjust/TLO switch, or a general purpose 10k Ohm thermistor/dry contact input. Inputs 3 and 4 of the T540 and T540v modules are jumper selectable for either 0-5 VDC (with a sensor output impedance of 10k Ohm or less), or 10k Ohm thermistor/ dry contact (see Figure 23). Note that the enhanced zone sensor, if used, requires two of the T-Line's inputs.

Some current switches that are not true contact closures may not go to zero Ohms when the switch is closed. Any switch which has more than 412 Ohms effective resistance (0.2 V) when closed must have an interposing relay when used with T-Line modules.

NOTE: The output impedance of any 0-5 VDC source should not exceed 10k Ohms.

Procedure

1. Remove the T-Line's power jumper.

2. Check the sensor wiring for shorts and grounds.

3. Terminate the sensor wires to the Input and GND terminals as shown in Figure 23. See "Using Quick Disconnects" for guidelines.

4. Select the proper jumper settings for inputs 3 and 4 (modules T540 and T540v only).

5. Replace the T-Line's power jumper.

Rev. (29-JUN-99) • TNI v4.7

6. Verify the input by measuring the voltage between the GND terminal of the analog input and the positive terminal. The input voltage for thermistors should be between 0 and 5 V.

7. Enter the channel number, offset, and gain on the T-Line zone FB parameter page as listed in the "Channel Number" section.

Custom Translation Tables

In addition to the inputs already mentioned, it is possible to create custom translation tables for non-standard thermistor or slidepot inputs. Provided on the parameter page of the TNI module driver are two user-definable tables for translating these inputs.

The following are typical applications for the custom translation tables:

• Thermistors other than Type 2 (such as Type 3).

• Slide potentiometer inputs.

• Non-linear voltage inputs (0-5 VDC maximum

range).

These tables use a 10 point linear translation method to approximate a non-linear curve of resistance or voltage to the desired units.

Procedure

Input Ohms Input Value

0 x 10 Ohms = 300

230 x 10 Ohms = 150

405 x 10 Ohms = 120

752 x 10 Ohms = 90

935 x 10 Ohms = 80

1172 x 10 Ohms = 70

1478 x 10 Ohms = 60

1879 x 10 Ohms = 50

2406 x 10 Ohms = 40

7032 x 10 Ohms = 0

32767 x 10 Ohms = -60.8

Figure 24: Example Custom Table for a Precon Type 3

Thermistor Sensor

4. Determine the resistance or voltage at the desired settings. This information may be obtained either from manufacturer reference tables or through testing.

5. Select a custom translation table that is not currently in use. Record the custom gain from this table for use when defining inputs which will use the custom translation table in the module.

6. Enter the scaled voltage or resistance input on the left and then enter the corresponding value on the right (see Figures 24 and 25 for examples).

1. Display the TNI module driver parameter page (FB #15).

2. For thermistor, slidepot, and other resistance inputs set the option "Is input specified in voltage?" to NO. For voltage inputs, set the option to YES.

3. Determine the accuracy and range needed. Note the following:

• Values which lie between two defined entries are

interpolated linearly by the FB.

• The first and last entries of the resistance table

should always be set to zero and infinity (32767 x 10 represents infinity) in the event that the sensor should short or open. In the case of voltage inputs, the first and last input voltages should be set to zero and 5 V. These are the default values.

The resistance values of the slidepot in Figure 25 (left column) were obtained by measuring the

Input Ohms Input Value

0 x 10 Ohms = -1.00

474 x 10 Ohms = -1.00

607 x 10 Ohms = -0.75

910 x 10 Ohms = -0.50

1210 x 10 Ohms = -0.25

1540 x 10 Ohms = 0.00

1860 x 10 Ohms = 0.25

2150 x 10 Ohms = 0.50

2360 x 10 Ohms = 0.75

2400 x 10 Ohms = 1.00

32767 x 10 Ohms = 1.00

Rev. (29-JUN-99) • TNI v4.7

resistance of the positions of the slidepot in 1/8 increments (far left, 1/8, 1/4, 3/8... far right).

Note that the slidepot input values (see Figure 25, right column) are defined with a setpoint-bias rather than absolute temperatures. These input values are multiplied by the "Enhanced Sensor: Setpoint Input Bias" parameter (see Figure 31) as the slidepot is adjusted (see Note #3 below) and then added to the zone setpoint. This method allows you to globally modify the above parameter for all T-Line function blocks in the TNI module instead of changing the lookup table parameters for each zone.

7. Download parameters to this FB.

8. To activate these tables enter the gain of the

translation table used (either 15.00 or 15.06) on the T-Line FB parameter pages that contain the input for which the table applies. Set the offset to 0.00.

NOTES:

1. The minimum resistance for the slide pot can not go

below 4.7k Ohms. If the resistance does go below

4.7k Ohms, insert a 4.7k Ohm resistor in series with the slide pot. A zero Ohm reading may simulate a

TLO pulse to the module in cases where a TLO momentary contact may be in parallel with the slidepot.

2. The lowest resistance range allowed on a slidepot input is 5k Ohms. This guarantees that sufficient resistance exists between steps to allow for good linear approximation.

3. To be able to set the "Enhanced Sensor: Setpoint Input Bias" parameter for slidepots, the slidepot must be connected to input 2 (pins 3 and 1 in place of the RSZ+).

Some field adjustment of parameters may be necessary in order for the flow readings on the T-Line VAV Control FB to match the reading obtained during the test and balance procedure. The calibration process consists of two phases: (1) adjusting the flow sensor zero point, and (2) adjusting the flow sensor gain.

This process may be conducted at the RSZ+ if the procedure described in the "Local Access" section was followed.

Adjusting the Zero Point

Use the following procedures to adjust the flow sensor's zero point.

1. Turn off the AHU serving the VAV box to be calibrated.

2. Select the TNI module driver (FB#15) for the module to be calibrated.

3. Display the status page.

4. Note the FB's Current Value(s) and 0.00 Value(s) from the Calibration Table (See Figure 29).

Figure 27: Flow Sensor connections

3. Connect the flow sensor by attaching the positive total pressure line to the transducer's HI side and attaching the static pressure line to the transducer's LO side (see Figure 27).

NOTE When connecting tubing to the sensor ports, grasp the housing between your thumb and forefinger so that the port designation is covered and the port is supported. Ease the tubing onto the port. Do not expose the port to forces greater than 5 pounds in a direction perpendicular to the port centerline. Thin-walled 1/4" Tygon or equivalent tubing is recommended.

4. Replace the T-Line's power jumper.

Rev. (29-JUN-99) • TNI v4.7

5. Display the parameters page.

6. Note the Flow Zero Offsets line from the parameters page (See Figure 28).

7. Calculate the Offsets for each FB as follows:

• FB# Flow Zero Offset = 0.00 Value - Current

Value

Example for determining the FB# Offset:

FB#1's 0.00 Value = 130

FB#1's Current Value = 128

FB#1's Flow Zero Offset = 130-128 = 2

8. Enter the calculated FB#(s)'s Flow Zero Offset in the appropriate FB# on the parameter page (See Figure

27).

Older versions of the T-line (Revs 3 and 4, see Figure 28) had fuses and fuse sockets to protect the board from surges and wiring errors on the communication terminals. These fuses have been replaced with 100 Ohm resistors to allow wiring mistakes and power surges to occur without having to replace blown fuses. This change to 100 Ohm resistors necessitated reducing the number of T-modules to 20 modules maximum and 1500 feet of wire maximum. For greater than 20 boards, or 1500 feet of wire, a REPOPT must be used as shown in Figure 6. If you are installing a newer T-module that has 100 Ohm resistors into an existing older T-net that has more than 20 modules, replace the 100 Ohm resistors with 0.125 (1/8) amp pico fuses (order ALC part number FUSEPKG).

Production Date

The production date of the module can be determined by a sticker on the front of the module. The first three characters indicate the type of module. The next three indicate the date (year/month/week) of manufacture. The month is in hexadecimal. The last four characters are ALC production codes.

Using Quick-Disconnects

T-Line boards are designed with male quick-disconnect terminals upon which female quick-disconnects are fixed. A quick-disconnect connector is fastened to a wire by means of a crimper. All quick-disconnect connectors for the T-Line boards must be 0.032 inches thick. These connectors are available from manufacturers such as AMP, T&B, and 3M.

Crimping & Terminating QuickDisconnects

WARNING: Always follow proper safety precautions when handling wires to avoid electrical shock or equipment damage.

1. Using a wire stripper, strip about ¼" of insulation

from the wire.

2. Insert the bare wire into the cylindrical end of the

female quick-disconnect until it is almost within the flatter portion.

3. Crimp the cylindrical end of the quick-disconnect to

the wire using a crimper as shown in Figure 30.

4. Terminate the wire by firmly pushing the connector onto the desired quick-disconnect terminal, as shown in Figure 31.

Removing Quick-Disconnects

When removing connectors from the quick-disconnect terminals, rock the connectors from side-to-side while pulling, as shown in Figure 32.
