The modifications of the controller configuration and parameter settings described in this sec tion can only be performed after the valid key number has been entered.

The valid key number for initial start-up can be found on page 123. To avoid unauthorized use of the key number, remove the page ormake the key number unreadable. In addition, it is pos sible to enter a new, customized key number (–> section 7.15).

2.1 Setting the system code number

21 different hydraulic schematics are available. Each system configuration is represented by a system code number. The different schematics are dealt with in section 4. Available controller functions are described in sections 5, 6 and 7.

Changing the system code number resets previously adjusted function blocks to their default set tings (WE). Function block parameters and parameter level settings remain unchanged. The system code number is set in the configuration and parameter level.

2.4 Calibrating sensors

The controller is designed for the connection of Pt 1000 sensors. The resistance values of the Pt 1000 sensors can be found on page 112.

If the temperature values displayed at the controller differ from the actual temperatures, the measured values of all connectedsensors canbe readjusted.To calibratea sensor,the currently displayed sensor value must be changed such that it matches the temperature (reference tem perature) measured directly at the point of measurement. Sensor calibration is to be activated in CO5 via function block F20. An incorrect sensor calibration can be deleted by setting F20 - 0.

5.1 Weather-compensated control

When weather-compensated control is used, the flow temperature is controlled according to the outdoor temperature. The heating characteristic in the controller defines the flow temperature set point asa functionof theoutdoor temperature(–> Fig.5). The outdoor temperature required for weather-compensated control can either be measured by an outdoor sensor or it can be re ceived over an 0 to 10 V input.

6.8 Priority operation

In many district heating systems with primary DHW heating, the allotted amount of water can not meet DHW heating and heating operation demands when they are required at the same time. As a result, the capacity requiredfor DHWheating needs to be taken from the heatingsys tem when great heating loads occur; and this, until DHW demand has been concluded. Nevertheless, heating operation is not to be interrupted simply. Only the amount of energy re quired for DHW heating is to be deducted. This can be achieved by using the priority functions Reverse control and Set-back operation.

For the individual controller, this means that storage tank charging is activated when the water temperature in the storage tank falls below theadjusted deactivation valueof T =

7.3 Forced operation of the pumps

When the heating circuit pumps have not been activated for 24 hours, forced operation of the pumps is started between 12.02h and 12.03h. This is done to avoid that the pumps get stuck when they are not operated for a longer periodof time.In the DHW circuit, the circulation pump is operated between 12.04h and 12.05h, the other pumps between 12.05h and 12.06h.

7.4 Return flow temperature limitation

The temperature difference between the flow and return flow indicates how well the energy is used: the greater the difference, the higher the efficiency. A return flow sensor is sufficient to evaluate the temperature difference when theflow temperaturesare preset.The returnflow tem perature can be limited either to a value depending on the outdoor temperature (variable) or to a fixed set point. When the temperature measured at return flow sensor RüF exceeds the limit value, the set point of the flow temperature (flow temperature of the heating system, charging temperature) is reduced. As a result, the primary flow rate is reduced and the return flow temperature falls. In systems Anl 2.x and 4.1, the

7.9 Releasing a control circuit/controller over the binary input

The release of an individual control circuit or the controller using the binary input only becomes effective when the respective control circuit is in automatic mode (icon ). The released control circuit always works in automatic mode; the deactivated control circuit behaves as if it were transferred to stand-by mode . It remains active, however, in any case for processing of external demand. The control circuit can be releasedvia thebinary inputwhen the binary input is either a make contact (bE = 0) or a break contact (bE = 1).

Note:

In systemswith supplementary heating circuit without a valve(Anl 2.x, 4.x), BE1 only influences the operation of this heating circuit. In system Anl 3.0, BE1 influences the operation of the entire controller (except for processing of an external demand).

7.10 Processing of external demand in control circuit Rk1

The controller can process binary or analog requests for an externally required signal by a more complex secondary system, provided the inputs SF2 or RF2 are not assigned to a sensor. The standard 0 to 10 V signal is basically intepreted asa0to120°Cflow temperature de mand, i.e. the flow temperature demand is 12 °C/V.

NOTICE

Overheating may occur in the heating circuits of the primary controller without control valve.

Excessive charging temperatures in DHW circuits without control valve controlled by the pri mary controller are excluded when the default settings of the controller are used: while storage tank charging is active, no flow temperature higher than the charging temperature is used by the primary controller. Nevertheless, if the Priority for external demand function is activated, the external demand is also processed during storage tank charging.

8.5 Sending text messages in case of error

If a dial-up modem is connected to RS-232/modem communications module (-> section 9.1), the controller can send a text message to a mobile phone when an error occurs. As soon as a fault has been registered in the error status register, the text message indicating a controller fault is sent. On the mobile phone, the following error message is displayed:

[Date] [Time] [Phone no. of the controller] Controller fault TROVIS 5573 # [controller ID of the faulty controller]

80 EB 5573 EN

Page 81

Operational faults

The time stamp [Date], [Time] is added by the text messaging center, not by the controller. If an error message is transmitted via the device bus to a controller equipped with a dial-up modem, the controller ID of the faulty controller is sent, instead the controller ID of the “modem control ler”. A detailed error message is not available.

Note: The controller ID is indicated in the extended information level under Info 2 listed as the first value in the sequence (-> section 1.8).

When Modbus is activated and, at the same time, the dial-up in case of error is released, the connection with the building control station is established first, and then the text message is sent. If the first attempt to connect to the building control station fails, the controller tries again until the programmed number of redialing attempts has been exhausted.

In Germany, the access numbers (TAPnr) of the SMS service center are currently:

D1 network: 0171 252 1002 (alternatively, 0171 252 1099 is also possible)

9.1 RS-232/modem communications module

When lookingonto thecontroller front, the connection for the optional communications module is located on the left side in the controller housing (RJ-45 jack). A dial-up modem can be con nected to the controller over the RS-232/modem communications module. A dial-up modem is required in case the controller is to be connected to the telecommunications network. In this case, the controller works autonomously and can issue an alarm call to the building controlstation when errors occur. Additionally, the buildingcontrol station can dial up to the controller, read data from it, and send new dataonce thevalid keynumber has been writ ten to holding register no. 40145.

Note: If a wrong key number has been written to holding register no. 40145 for the third con secutive time, the controller immediately interrupts the modem connection and generates an “Err 7“ error message (Unauthorized access occurred). As a result, the call to the configured control systemis triggered and a textmessage is sent. Bit D6 is deleted assoon as the error sta tus register has been read by the control system and the connection has been terminated.

In special cases, the Lock dial-up function can be selected to stop dial-up in case an error occurs. Using the Dial-up also upon corrected error function, the controller additionally informs the building control station when a previously signaled error no longer persists.

Thanks to the Automatic modem configuration function, the dial-up modem connected to the controller does not need to be preset; it is configured automatically by the controller.

9.2 RS-485 communications module

When looking onto the controller front, the connection for the optional communication module is locatedon the left side in thecontroller housing (RJ-45 jack). A constant bus connection isre quired (data cable) to operate the controller together with the RS-485 communcation module. The bus line links the control units/devices in an open ring. At the end of the bus line, the data cable is connected to the control station using a RS-485/RS-232 converter (e.g. CoRe01, refer to Data Sheet T 5409 EN).

The maximum range of the bus connection (cable length) is 1,200 meters. A maximum of 126 devicescan beconnected to such a segment. For greater distances or when more than 126 devices are to be connected to a line, repeaters (e.g. CoRe01) must be used to regenerate the level. A maximum of 246 devices with 8-bit addressing can be connected to a bus.

If no communication is established between the control system and controller, the time of any access by the control system to dynamic process can be restricted by the Control system moni- toring function. The controller resets the monitoring function, provided the valid Modbus requests are registered. However, in case of an error, all level bits are initialized back to “autonomous” after 30 minutes have elapsed.

NOTICE

You are required to follow the relevant standards and regulations concerning lightning and surge protection on installation.

9.3 Description of communication parameter settings

Station address (ST)

This address is used to identify the controller in bus or modem mode. In a system, each control ler needs to be assigned a unique address.

Modem dialing pause (P)

It is recommendable to pause for approx. 3 to 5 minutes between dialing up to the control sys tem/the text messaging center to avoid a permanent overloading of the telecommunications network. The

Modem time-out (T)

When thecontroller connects to the control station (GLT)but without addressing a Modbus data point, the connection is terminated after the time specified for the error status register has not been read during the GLT connection, the controller dials up the GLT again after the When sending a text message, the specified time is without meaning.

Number of redialing attempts (C)

The controller tries to dial up to the control system again, observing the in case the GLT/text messagingcenter isbusy orthe functionthat triggeredthe callhas notbeen reset bythe controller. After the specified number of redialingattempts have failed, “OFF“ is indicated in the controller's extended information level. The dialing attempt counter is automatically reset at 12:00h and the controller tries to connect again. Resetting of triggered call = Reading the error status registers (HR40150)

Phone number of control station (TELnr)

Enter the phone number of the control system modem including the dialing code, if necessary. Short pauses between the numbers can be entered using P (= 1 second); the end of the string is to be marked by “–“. The phone number may include a maximum of 22 characters. Example: “069, 2 sec. pause, 4009, 1 sec. pause, 0“: 0 6 9 P P 4 0 0 9 P 0 – (= 11 characters)

9.4 Memory module

The use of a memory module (order no. 1400-9379) is particularly useful to transfer all data from one TROVIS 5573 Controller to several other TROVIS 5573 Controllers.

The memory module is plugged into the RJ-45 jack at the side. Once the module has been con nected, “73 SP“ is displayed. If the memory module already contains data from a different TROVIS 5573 Controller, turn the rotary pushbutton until “SP 73" is displayed.

Pressing the rotary pushbutton to confirm “73 SP“ causes the controller settings to be trans

ferred to the memory module. Pressing the rotary pushbutton to confirm “SP 73“ causes the saved controller settings to be

transferred from the memory module to the controller.

During the data transfer, the bars on the display indicate the progress. When the transfer was successful, “I.O.“ is displayed. After that, the connection between controller and memory mod ule can be terminated.

Using TROVIS-VIEW (order no. 6661-1014), it is possible to configure all controller settings in a convenient user interface on the PC and to document these settings.

9.5 Data logging

A data logging module (order no. 1400-9378) saves the following controller data every two minutes:

Temperatures measured by the sensors

Control signals [%]

Switching states of the pump outputs

Error status register and its archive data

Access to the controller settings

The data logging module is connected to the RJ-45 jack at the side of the controller. The controller starts to write over the oldest data as soon the memory of the data logging mod

ule is full after approximately eight days. The current memory capacity of the data logging

Info 2

module can be read in the extended information level under quence (range of values: 0 to 6035). Directly after inserting the data logging module, data can be first read after the first scanning cycle has been performed.

The Datalogging Viewer software allows the data to be viewed in graph format. The USB converter 3 (order no. 1400-9377) is required to connect the data logging module to a com puter. The Datalogging Viewer software is supplied with the USB converter 3.

Danger!

Risk of electric shock!

For electrical installation, you are required to observe the relevant electrotechnical regulations of the country of use as well as the regulations of thelocal powersuppliers. Makesure all electri cal connections are installed by trained and experienced personnel!

Notes on installing the electrical connections

Install the 230V powersupply linesand thesignal lines separately! To increase noise immu

nity, observe a minimum distance of 10 cm between the lines. Make sure the minimum dis tance is also observed when the lines are installed in a cabinet. The lines fordigital signals(bus lines)and analogsignals (sensorlines, analog outputs) must

also be installed separately! In plants with a high electromagnetic noise level, we recommend to use shielded cables for

the analog signal lines. Ground the shield at one side, either at the control cabinet inlet or outlet, using the largest possible cross-section. Connect the central grounding point and the PE grounding conductor with a cable≥10 mm² using the shortest route. Inductances in the control cabinet, e.g. contactor coils, are to be equipped with suitable in-

terference suppressors (RC elements). Control cabinet elements with highfield strength, e.g. transformers or frequency converters,

should be shielded with separators providing a good ground connection.

Overvoltage protection

If signal lines are installed outside buildings or over large distances, make sure appropriate

surge or overvoltage protection measures are taken. Such measures are indispensable for bus lines! The shield of signal lines installed outside buildings must have current conducting capacity

and must be grounded on both sides. Surge diverters must be installed at the control cabinet inlet.

Connecting the controller

The controller is connected as illustrated in the following wiring diagram. Open the housing to connect the cables. To connect the feeding cables, make holes in the

marked locations at the top, bottom or back of the rear part of the housing and fit suitable grommets or cable glands.

90 EB 5573 EN

Page 91

Electrical connection

Connecting the sensors

Cables with a minimum cross-section of 2 x 0.5 mm² can be connected to the terminals at the back panel of the housing.

Connecting the actuators

0 to 10 V control output:

Use cables with a minimum cross-section of 2 x 0.5 mm². Three-step or on/off outputs:

Connect cableswith at least 1.5 mm²suitable for damp locations to the terminals of the con troller output. The direction of travel needs to be checked at start-up.

Connecting the pumps

Connect all cables with at least 1.5 mm² to the terminals of the controller as illustrated in the wiring diagram.

CAUTION!

The electric actuators are not automatically supplied with a voltage by the controller. They can be connected over terminals 25 and 28 to an external voltage source. If this is not the case, connect a jumper from terminal 18 to terminals 25 and 28.
