TCX2-Series Communicating Cabinet Mounted Universal Controller
Applications
General
The TCX2 is a programmable electronic universal controller with communication capabilities. Each control loop may use 2 PI
sequences and 6 binary stages. The TCX2 comes with a built in RS485 communication interface that allows peer to peer
communication with an operation terminal e.g. OPU2-(2TH)-VC or a PC.
Communication plug-ins allow for integration of the controller into a network. These modules are described in their own
manual. Currently available are plug ins for BACnet and MODBUS.
Flexible application configuration is made with a parameter-setting routine using the standard operation terminal.
Complete parameter sets may be copied by use of an accessory called AEC-PM1 or exchanged with a PC using an RS485-USB
converter and the EasySet program.

Installation
See installation sheet no. 70-000599 (www.vectorcontrols.com).
Selection of actuators and sensors
Temperature sensors: Use Vector Controls NTC sensors to achieve maximum accuracy: SDB-Tn10-20 (duct), SRA-Tn10 (room),
SDB-Tn10-20 + AMI-S10 as immersion sensor.
Actuators: Choose modulating actuators with an input signal type of 0-10 V DC or 4-20 mA (Min. and max. signal limitations
may be set with parameters. 3-point point actuators with constant running time are recommended.
Binary auxiliary devices (e.g. pumps, fans, on/off valves, humidifiers, etc.): Do not directly connect devices that exceed
specified limits in technical specifications – observe startup current on inductive loads.
Electrical connections
Use only twisted pair copper conductors for input connections. The operating voltage must comply with the requirements for
safety extra-low voltage (SELV) as per EN 60 730.
Use safety insulating transformers with double insulation. They must be designed for 100% ON-time. When using several
transformers in one system the connection terminal 1 must be galvanically connected. The TCX2 is designed for operation by AC
24 V, max. 10 Amp, safety extra-low voltage that is short-circuit-proof. Supplying voltages above AC 24 V may damage or
destroy the controller or any other connected devices.
Additionally, connections to voltages exceeding 42 V endanger personnel safety. Observe limits mentioned in the technical
specifications. Local regulations must be observed at all times.

Idle display
The idle display is activated when no key has been pressed for 30 seconds.
The contents of the idle display are selectable through parameters UP08 to UP14.
Setting UP08 to OFF will disable idle display. Last active control loop or manual output will remain displayed.
Display of control loop
Active when changing set points. Large digits show input value. Small digits show set point. Horizontal bars top left show which
loop is being displayed.
Override of secondary set point in cascade control
If cascade control is active (with VAV for example) the user can override the primary loop and manually select the set point of the
secondary loop (the loop is then changed to constant air volume mode). This function is helpful for tuning the VAV system. This
feature may be disabled by setting UP02 to OFF.
While the secondary loop is displayed change the set point with UP/DOWN. The hand symbol appears.
Change setpoint again to cancel cascade override. The hand symbol disappears.
Delay on enable function
During a pending delay the hand symbol will be shown. For example the condition to activate the controller with 1FU is met, but a
startup delay is specified. The controller will remain switched off and show the hand symbol until the delay expired.

New Feature: TCX2 is in no-reply-mode for OPU2-VC communication
OFF = TCX2 is in normal mode for communication with OPU2-VC
ON = TCX2 is in no-reply-mode for communication with OPU2-VC
No-reply-mode: This mode allows connecting one operation terminal to multiple controllers.
One controller must be in normal operation mode and all the others must be set to no-replymode. The controllers set to no-reply-mode will follow each command issued by the operation
terminal. They will not send responses and their alarm conditions are not monitored by the
operation terminal.
Setting a controller with only one operation terminal to no-reply-mode will result in
communication error on the operation terminal. In this case parameter UP22 can still be
changed to 0 through the operation terminal.

Setting parameters to configure the controller
TCX2 is an intelligent controller with the flexibility to fit a wide range of applications. The control operation is defined by
parameters set using the standard operation terminal. There are two levels:
1. User/display parameters (password 0009)
2. Control parameters (password 0241)
Recommended set-up procedure:
1. Set jumpers on the back of the controller for inputs and outputs
2. Connect power supply and inputs
3. Make sure Celsius – Fahrenheit settings are correct (UP07)
4. Program input parameters
5. Program control parameters
6. Program output parameters
7. Program auxiliary functions and user settings
8. Test function of unit
9. Switch off power
10. Connect outputs
11. Reconnect power
12. Test control loop
Parameters are grouped according to modules:
How to change parameters
1. Press UP/DOWN buttons simultaneously for three seconds. The display will show firmware version and revision number.
Press the OPTION button to start login.
2. CODE is shown in small display. Select 241 or the number provided by your supplier using the UP or DOWN button. These
are the default access numbers, your supplier may have changed those numbers or blocked access to the parameters
completely. Parameters should only be changed by authorized personnel.
3. Press OPTION after selecting the correct code. The user/display parameters are displayed immediately.
4. Once logged in with 241 control modules are displayed (UI, AL, LP, AO, FAN, DO, CO etc.) – select with UP/DOWN and open
with OPTION. Then select the ID with UP/DOWN keys: 1U, 2U, 3U etc., open with OPTION. As soon as the module is open its
parameters are displayed.
5. Select the parameters with the UP/DOWN buttons. Change a parameter by pressing the OPTION button. Three arrows are
displayed to indicate that the parameter may be modified. Use UP/DOWN buttons to adjust the value.
6. After you are done, press OPTION to save the new value and return to the selection level (arrows disappear when selection is
saved). Pressing left hand POWER button without pressing OPTION will discard the value and return without saving.
7. Press POWER to leave parameter selection and return to control module selection.
8. Press the POWER to leave the menu. The unit will return to normal operation, if no button is pressed for more than 5
minutes.
How to select active alarms on outputs and special functions
1. Select the parameter as described above
2. Press OPTION to start selecting alarms. AL 1 is now shown in the large digits.
3. Press UP to select the alarm 1, press DOWN to deselect the alarm 1. A selected alarm is visible by a dark triangle on the
bottom line of the LCD. The output or function will activate if the corresponding alarm is triggered.
4. Press OPTION to step to alarm 2. Repeatedly press OPTION key to step through all available alarms and select or deselect
them by pressing UP or DOWN.
5. Press POWER to leave the alarm selection routine and return to the parameter selection level.

TCX2 Universal Controller
SETUP AND CONFIGURATION
Copying and restoring the entire parameter set
It is possible to backup and refresh the entire parameter set to a second onboard memory (default memory) or a plug-in memory.
This simplifies substantially the programming of multiple controllers with identical parameter sets.
Removable plug-in memory AEC-PM1
The plug-in memory is an accessory that can be plugged in on the right side of the TCX2. Once connected, the power LED on the
AEC-PM1 lights up. The memory can hold up to 4 individual parameter sets. It is easy for a site engineer to update a variety of
standard installations or for an OEM to program his standard setup based on application.
Auto-load
While copying a parameter set to eeprom, the user may choose the auto-load feature. With this feature set, the parameters load
automatically when powering up the controller. It is thus possible for a non-technical person to perform a parameter update by
simply powering up the controller with the AEC-PM1 plugged in.
Procedure to copy parameter sets
1. Login to engineering parameters as described above.
2. Press UP or DOWN until COPY is selected
3. Press the OPTION key. Select copy source: These are the options:
4. Press OPTION key. Now select copy destination: These are the options:
5. Press OPTION key. Your selection is shown on the large digits: source ID to target ID. For example run time memory to
6. Press the OPTION key to conclude the selection. The Data LED on the AEC-PM1 plug-in blinks to indicate data
Exchanging parameter sets with a computer
Through a USB/RS485 converter it is possible to read and write parameter sets to a computer by the use a free program called
EasySet. The EasySet tool may be downloaded from the vectorcontrols.com website.
To exchange parameter sets, install the EasySetTM configurator program and plug in the USB/RS485 converter to your computer.
Connect the RS485 converter to the OP3 (+) and OP4 (-) terminal of the TCX2 using a twisted pair wire. If an OPU2-VC is
connected, you must first unplug it. In order to use EasySet, select the port of your USB converter first.
Parameter sets may now be read out from the TCX2 to the PC and written back to the TCX2. This makes it possible to keep a
parameter library on computer, exchange parameter sets through emails or keep a log file of all the projects completed.

There are several possibilities for the result:
Good: The copy process was successful
Fail: Err5, Communication problem. The plug in module is either damaged or missing
Fail: Err6, Checksum mismatch. The checksum of the source data was incorrect. Data corruption. This may
happen if the plug-in has not been written to before or data corruption took place.

Input & alarm/interlock configuration
Universal inputs (analog, binary or passive)
Set jumpers on the back of the controller: 0–10VDC (default), 0–20mA, or RT/DI (passive temperature or binary)
Match sensor range to input display. With a differential pressure transmitter having 0–200 Pa measuring range set 01U1
display minimum to 0 and 01U2 display maximum to 200. The allowable range value of -50–205 may be adjusted with
multipliers in 01U3. The largest displayable values are -990–9999.
Passive temperature input is NTC 10k@25°C (77°F). Specified accuracy can only be guaranteed using Vector Controls Sxx-
Tn10 sensors. Range values described above also apply to temperature inputs.
Display resolution (01u1 and 01u2)
Limiting the display range increases set point resolution. A range <25 provides set point steps of 0.1°C (0.2°F). A range
<125 provides set point steps of 0.5°C(0.1°F). Larger ranges increase by 1 step. Square root input range (0xu3) has no
influence.
Note: Fahrenheit and differential steps are doubled.
New Feature: open contact as input type (01u0 = 4 or 5): For an open contact input set the jumper to RT/DI and
parameter 01u0 to open contact (4 or 5). If set to 4 (open contact direct), an open contact reads as a high value (100%), a
closed contact as a low value (0%). If set to 5 (open contact reversed), an open contact reads as low value (0%) and a
closed contact as high value (100%). Note: sensor calibration does not work for binary inputs.
New Feature: potentiometer input (01u0 = 6). A potentiometer may be connected to a passive input to control the
setpoint of a control loop. With the input display minimum and maximum values the range of the potentiometer can be
defined in 100 ohms steps. For example setting the 1u01 to 50 and 1u02 to 120 represents a potentiometer from 5k to 12k
Ohm. The resistance is measured and calculated into a 0-100% value. Based on the potentiometer input, the setpoint will
now be moved between the upper and lower setpoint limits of the control loop. There are other uses for the potentiometer
input. For example, the controller can be enabled and disabled remotely with a potentiometer using an input in
potentiometer mode assigned to the Auxiliary Function Enable/Disable (1FU). Or use Alarm/Interlocks assigned to the
potentiometer input to activate or deactivate outputs. With the potentiometer fully on, for example, another interlock could
activate a boost mode. The potentiometer could then read OFF (65°F) to Full (85°). Add one more wire connected to a 10k-2
resistor and measure the room temperature as well. Thus with 3 wires in total ( potentiometer, common, room temperature)
a well-functioning low cost operation terminal may be realized.
