2 Operation

Synco™ 700 devices may only be operated by staff who have been instructed by SBT HVAC Products or their delegates and whose attention has been drawn to potential risks.

2.1 Functions of the bus operator unit

The RMZ792 bus operator unit is used to make all settings and readouts required for operating a device. All entries made on the bus operator unit are transmitted to the respective device where they are handled and stored; the operator unit itself does not store any data. The information required by the user is generated by the devices and transmitted to the operator unit for display. The text catalog in different languages and the description of the operating structure of all operable Synco™ 700 devices are stored locally on the exchangeable memory card (RMA792) in the operator unit.

2.2 Operating concept

On the software side, all settings and readout values are arranged as datapoints (operating lines) of the menu tree. Using the operating elements, every datapoint can be selected, displayed or set. All menus appear on the LCD as clear-text. The bus operator unit has several languages preprogrammed; when commissioning the plant, the required language must be activated. The Operating Instructions for the user are integrated in the Installation Instructions (G3113).

3112P01

3.2 Remote operation and local operation

The bus operator unit provides access to the datapoints of the bus users’ user and service levels. But the datapoints of the bus users’ password level are to be accessed via the local RMZ790 and RMZ791 operator units. For this reason, the RMZ792 bus operator unit cannot be used for configuring and commissioning plant.

3.3 Navigating on the device list

During commissioning, the device list (list containing all bus users) is generated. Datapoints are always to be accessed via the device list – with the exception of the favorite pages (refer to section 3.4 “Quick access with favorites”). By selecting the required unit from the device list, the operator reaches the menu tree of the unit needed.

Menu tree and navigation are not any different from local operation with the RMZ790 or RMZ791.

When pressing the INFO button during navigation, the following information is displayed:

15/52

Building Technologies Bus operator unit RMZ792 CE1P3113en HVAC Products 3 Operation of devices 03.04.2006

Page 16

• The device name and – if appropriately set – the device address

• The current position in the menu tree (path)

• Long text relating to the selected datapoint

The information is displayed as long as the button is kept depressed.

3.4 Quick access with favorites

The favorite pages provide a user interface matched to the requirements of every day use. On the favorite pages, simple datapoints of any devices from the device list can be combined. From their location in the menu tree of the respective device, the datapoints are copied to the required favorite page. This makes navigation much more efficient. All favorite pages are identified by the

symbol in the corner at top right. This makes it

easy to distinguish between favorite pages and the unit’s menu tree.

3.5 Information describing what is visible

Certain Synco devices deliver information that describes what is visible. When using this information, the user interface only displays datapoints that are important for the controller’s current configuration. If a device does not support this kind of information, the bus operator unit will display all available datapoints – independent of the device’s configuration. For this reason, datapoints may assume values that do not make sense and setting values may not trigger any actions because the device’s current configuration does not support them or they are inactive.

The following types of devices do not contain information describing what is visible:

3.6 Error handling

Possible cases

Error / error message Cause / remedy

Caution! Device version not supported

• The device description version of the bus operator unit and the software version of the target device do not match

• Find compatible versions of memory card and device (VVS)

• Exchange the memory card (RMA792) of the bus operator unit or the target device

16/52 Building Technologies Bus operator unit RMZ792 CE1P3113en

HVAC Products 3 Operation of devices 03.04.2006

Page 17

Error / error message Cause / remedy

Caution! Device not responding

• Communication with target device is not possible

• Is the device in operation?

• Is the device connected to the Konnex

bus?

• Has the device address been changed?

Datapoint shows a value that does not make sense (e.g. room temperature 655.3 °C)

The device does not support information describing what is visible; datapoint has no meaning in the current configuration

Setting does not produce any effect The device does not support information

describing what is visible; datapoint has no meaning in the current configuration

3.7 User-defined text

User-defined text from the devices is adopted, which means that the display on the bus operator unit is identical with that on the local operator unit (RMZ790 / RMZ791). The bus operator unit reads the user-defined text from the respective device. The RMZ792 displays the default text until the text from the device is received.

Notes

4 Power supply

The bus operator unit can be powered in 3 different ways:

• Via Konnex bus (45 mA)

• Via an external power source (AC 24 V)

• Via the service interface of a Synco™ controller (not recommended)

• When using the cable supplied with the bus operator unit, plug correctly the RJ45

connector into the appropriate socket of the RMZ792 (audible click)

• Move the KNX / EXT slide switch for selecting the type of power supply to its end position

4.1 Power supply via Konnex bus

• If the bus operator unit is used in a location where AC 24 V power supply is not available (mobile use, installation in some other space), the unit can be powered via the Konnex bus

• Power supply must be such that 45 mA are available for the bus operator unit. This necessitates at least 2 active decentral bus power supplies via Synco™ controllers or 1 central bus power supply

• The slide switch at the rear of the bus operator unit must be set to KNX

• Using the cable supplied with the unit, the RMZ792 is to be connected to a Konnex

bus socket (figure a) or a Synco™ controller (figure b)

• The Konnex bus cable is to be connected to terminals CE+ and CE– on the base (figure c; observe polarity)

4.3 Power supply via Synco™ controller

• In exceptional cases, the bus operator unit can also be powered via the service interface of a Synco™ controller. Because of the additional power consumption of the bus operator unit, this type of power supply is possible only if the controller is equipped with no more than 3 extension modules

• The slide switch at the rear of the bus operator unit must be set to EXT

• The bus operator unit is to be connected to the service interface of the Synco™

controller using the cable supplied with the unit

If the bus operator unit is connected while the controller is in operation, the extension modules might deliver fault status messages. The faults may lead to short-time interruptions of plant operation. The fault status messages must be acknowledged and reset.

4.4 Error handling

Possible cases are:

Error Cause / remedy

Bus operator unit does not start Bus operator unit is cyclically

restarted Konnex bus is locked Operating values of the bus users

are not correctly displayed or cannot be changed

Backlit display very faint Controller indicates failure of

extension modules, parts of the plant fail

• Wrong polarity CE+ / CE–

• Wrong polarity G / G0

• Insufficient power supply via Konnex bus

(undersized bus power supply, too low bus voltage)

• Wrong slide switch position (KNX / EXT) or switch in an inadmissible intermediate position

• RJ45 connector not correctly plugged in (no contact)

The slide switch is in the EXT position and the bus operator unit was connected while the controller was in operation. Remedy:

1. Acknowledge the fault status messages and

reset them.

2. Connect the bus operator unit to a controller

with no extension modules or switch on the controller only after the bus operator unit has been connected.

Important!

6 “Commissioning” menu

• Prerequisite for trouble-free operation of the bus operator unit is correct assignment of the device addresses of all bus users including the line couplers

• The device addresses of all bus users and line couplers must accord with their positions in the network topology (area.line.address). Wrong device addresses can lead to unexpected responses and results when commissioning the bus operator unit

6.1 Device address

Like all other bus users, the bus operator unit must have an unambiguous device address. The device address can be set in 3 different ways. Depending on usage, one or the other method is the more suited. The RMZ792 is supplied with the device address set to 0.2.255 (area.line.address).

With device address 255, Synco™ devices do not send any process data. Device addresses 253 and 254 are reserved for special devices.

6.1.1 Automatic address search

• Automatic address search is recommended in situations where the bus operator unit is subsequently fitted to an existing plant without having knowledge of the existing address assignment

• At the request of the operator, the bus operator unit looks for the subnetwork address (SNA, consisting of area and line) in the superposed line coupler. If no subnetwork address is received, the last setting of area and line will be used

• Now, starting at 252, the bus operator unit searches for a free device address within the line. If the address is already used, a new automatic search attempt is made using an address whose value is reduced by 1. The search continues until a free device address is found. The device address is set to 255 if no free device address can be found

6.1.2 Manual assignment of addresses

• Manual assignment of addresses is recommended in situations where the bus operator unit has a firm place in the network and the address from a network plan has already been defined and is known

• Area, Line and Device address are manually predefined by the operator

• If the area or the line is changed, the bus operator unit looks for the subnetwork

address (SNA, consisting of area and line) in the superposed line coupler. When the line coupler delivers an SNA, the device adopts the line coupler’s SNA and overwrites any deviating manual settings. If no SNA is received, the set value of Area or Line will be adopted

• If the required device address is already used by some other device, the setting value will be reset to the previous value

6.1.3 Address assignment with the ETS

• This programming mode is used when addresses in the Konnex network are assigned with the ETS

• Area, line and device address are predefined in the ETS

• Set the Programming mode on the bus operator unit to On

• Use the ETS to load the respective device address

• After the bus operator unit has received the address, the Programming mode will

automatically change to Off

6.1.4 Error handling

Error Cause / remedy

No communication with other bus users The device address is 255, which means

that communication is not active. Set the device address to a value between 1 and 252 (automatic search or manual predefinition).

The subnetwork address (area or line) of the line couplers and / or the bus users do not correspond. Check the subnetwork addresses or

The subnetwork address (SNA) has not been adopted by the superposed line coupler

reassign them. There is no superposed line coupler, or

the line coupler is configured in a way that it does not send the SNA to the line. Configure the line coupler accordingly or

predefine the SNA manually. Fault status message 6001 >1 identical bus address

There are several bus users with identical

device addresses on the network. Correct

the device addresses on the respective

devices accordingly.

6.2 Activating communication

Communication is activated when:

• The device has a valid device address

• Bus power supply is available

• The device is not on the commissioning menu

6.2.1 Submenu “Communication”

A detailed description of communication is given in Basic Documentation P3127 “Communication via Konnex bus”. Basic knowledge of device addresses and network topologies is a prerequisite here.

Operating line Range Factory setting

Area 0…15 0 Line 0…15 2 Device address 1…255 255 Search address --- / Address found --Programming mode Off / On Off

Setting values Area, Line and Device address are used to manually create individual device addresses. Automatic address search is triggered via operating line Search address. A successful address search is acknowledged with status Address found. Status Address failed indicates that the address search has been unsuccessful. For assigning addresses via the ETS, the programming mode must be set to On. After successful address assignment, the ETS will automatically switch the value back to Off.

• If a line coupler superposed in the network topology delivers SNA information other than the values set for the area and the line, the line coupler’s values will be adopted

• If 2 devices have identical device addresses, an error message will be delivered

7 Data backup

• Making a backup copy of the settings

• Restoring the safe settings after unsuccessful changes

• Securing or restoring the settings when changing the memory card

When commissioning is completed, the settings of the bus operator unit can be saved. Later – e.g. after unauthorized changes or after inadvertent changes or deletions of settings – these settings can simply be retrieved.

Data backup or restoration of data can take place at 2 different locations:

• Locally, that is, on the memory card (RMA792) of the bus operator unit

• On the second device, that is, on the memory card of a second bus operator unit

connected to the bus

Storage on a second device is especially practical when, for compatibility reasons, the memory card of the bus operator unit must be replaced.

Data backup saves the following settings:

• Device list including the device name, order and display format

• Favorite pages with all datapoints

• Names and order of favorite pages

• Setting the display of fault status messages on the bus (refer to section 8.5 “Display

of bus fault status messages”)

All other settings (device address, language, etc.) will not be saved. After successfully restoring all settings, the bus operator unit will be restarted. The following status messages will be displayed, depending on the action performed:

Note

10 Faults

As a matter of principle, the bus operator unit only handles faults of devices contained on the device list.

When starting up, it can take up to 3 minutes for the device fault information to be updated, depending on the size of the device list.

When using network topologies with line couplers, it must be made certain that the line couplers forward correctly the devices’ fault information (LTE broadcast) to the bus operator unit (filter tables must be appropriately configured).

10.1 Display of faults

Fault status messages delivered by the bus users are displayed by the bus operator unit on a number of menus. Faults can be acknowledged by the bus operator unit and – if permitted by the respective device – can also be reset.

The fault LED in the fault button flashes or is lit when faults are pending:

State of LED Description

LED dark No faults pending LED flashes Unacknowledged faults LED lit Fault still pending or not yet reset

The state of the LED (flashing / steady on) can differ between the bus operator unit and a bus user if a fault relay has been configured on the operator unit.

Additional information about faults is given at different locations:

Location Description

Info page Fault status message bus Display of the most severe error (also refer

to subsection 10.1.3 “Info page and menu

“Fault status message bus”” Device list on the Main menu Fault symbol indicating faulty devices Menu Faults current List of a maximum of 20 faults sorted by

priority, state of acknowledgement and date

/ time of day Menu Fault status message bus Display of the most severe fault (also refer

to subsection 10.1.3 “Info page and menu

“Fault status message bus”” Fault menus of the respective de-

vices

Fault information from the local fault menus

in the menu tree of the respective control-

lers or devices (e.g. fault history)

The type of acknowledgement of a fault status message is determined by the fault source (e.g. Synco™ 700 controller). Depending on the type of acknowledgement demanded, a fault status message is acknowledged in one of the 3 following ways:

Type of acknowledgement Description

None Fault must neither be acknowledged nor

reset. The fault status message disappears

automatically when the cause of the fault

has been removed Acknowledge The fault is displayed until it is acknowl-

edged (even if in the meantime, the cause

of the fault has been removed) Acknowledge and reset The fault must first be acknowledged and,

after removal of the cause of fault, reset

10.1.1 Device list on the “Main menu”

Note

The fault state of the devices is shown on the main menu by a symbol on the right hand side. The symbols have the following meaning:

Fault symbol Description

Device in order, no fault pending Device faulty Device reads information about the fault Possibility of device failure, information about fault cannot be read

or is not periodically forwarded

After starting up the bus operator unit, it can take up to 3 minutes for the fault state of all devices to be updated, depending on the size of the device list.

10.1.2 Menu “Faults current”

Main menu > Faults > Faults current

This menu combines a maximum of 20 pending faults. The faults are sorted by fault priority.

The order of fault status messages on the fault lists of Synco™ controllers and the bus operator unit can differ, depending on priority information.

10.1.3 Info page and menu “Fault status message bus”

Fault status message bus and Main menu > Faults > Fault status message bus

The above example shows a “most severe fault” of all devices on the device list or of all Synco™ devices in the entire Konnex network. The display depends on the setting described in section 8.5 “Display of bus fault status messages”.

10.2 Faults of non-listed bus users

Fault status messages from bus users not contained on the device list are handled differently (refer to section 8.5 “Display of bus fault status messages”, depending on the setting of parameter Fault status message bus:

41/52

Building Technologies Bus operator unit RMZ792 CE1P3113en HVAC Products 10 Faults 03.04.2006

Page 42

Notes

• Setting Device list only: Fault status messages from non-listed bus users will be ignored.

• Setting All devices: If, at present, the fault status message from a non-listed bus user is the most severe pending, it will only appear on the menu and on info page Fault status message bus. The fault LED will not be lit. Acknowledgement and reset with the fault button is not possible and must be made locally on the respective device.

10.3 Acknowledgement of faults

When pressing the flashing fault button, all faults to be acknowledged will be acknowledged. Only faults of devices from the device list will be acknowledged. Acknowledgement can take place from any of the menus.

• When a device list is full, acknowledgement of faults can take up to 1 minute

• Faults of Synco™ devices not contained on the device list cannot be acknowledged

10.4 Resetting faults

Only faults of devices from the device list can be reset. In contrast to fault acknowledgements, faults must be reset on an individual basis. A reset is made by pressing the illuminated fault button. To ensure that the fault and the reset command can be unambiguously assigned, resetting of the current or the displayed fault can only take place on the following menus:

• On info page Fault status message bus of the bus operator unit

• On menu Fault status message bus of the bus operator unit

• On menu Faults current (faults 1…20) of the bus operator unit

• On the Main menu of the bus operator unit when the faulty device has been selected

• Locally on the faulty device (by pressing the fault button)

• Faults of Synco™ controllers can be reset via the bus operator unit only if setting

Remote reset of fault is activated. Example of universal controller type RMU710: Main menu > Commissioning > Communication > Basic settings

• Faults of Synco™ devices not contained on the device list cannot be reset.

10.5 Deleting faults

The fault history of a controller cannot be deleted from the bus operator unit; this is only possible locally on the actual bus user.

11 Memory card

11.1 Content of memory card

The exchangeable RMA792 memory card contains text catalogs in different languages and the device descriptions of the bus users. The version of the bus user and that of the respective device description must accord. For new versions or new types of Synco™ devices, the memory card must be updated, that is, exchanged. If incompatible, the bus operator unit will display an appropriate error message.

11.2 Exchanging the memory card

To exchange the memory card, the bottom of the housing must be opened. The memory card must be exchanged when power is disconnected. The memory card can be removed and replaced with no need for using a tool. When the unit is open, protective ESD measures must be observed; the electronic components on the printed circuit board must not be touched.
