Important Notes

Usage for the intended purpose

The operating & display unit URB 2 may only be used in conjunction with GESTRA CAN bus devices.

Any type of use differing from the usage described above must be considered as improper. The resulting risk will have to be borne by the user alone. The manufacturer hereby expressly rejects any claims for any damage resulting from improper usage.

Safety note

The equipment must only be installed and commissioned by qualified and competent staff. Retrofitting and maintenance work must only be performed by qualified staff who – through adequate training – have achieved a recognised level of competence.

ATEX (Atmosphère Explosible)

According to the European Directive 94/9/EC the equipment must not be used in explosion risk areas.

System description

The URB 2 is an operating & display unit for all GESTRA CAN bus devices that uses the CANopen protocol to register all the data telegrams coming from the sensors, control units and actuators that are provided by the CAN bus.

The following readings, parameters and settings can be displayed and – with the exception of the actual values – also be changed by means of the URB 2.

Function

The operating & display unit URB 2 evaluates at regular intervals the data telegrams of all sensors, controllers and actuators in a CAN bus system. The readings, parameters, settings and messages are indicated in plain text. When used as second water level indicator in boiler plants (TRD 401, EN 12952 /

...53), the level is also indicated in the form of a bar graph.

Several languages can be selected for plain text display.

The password protection prevents unauthorized persons from changing parameters and settings.

If other menu levels are selected via the start window and neither a button nor the navigation wheel is then actuated, the operating & display unit URB 2 will automatically return to the start window after 5 minutes. The time-out function is not effective during manual operation or in the parameterization mode.

The help function in the various operating levels offers additional information on how to operate the equipment.

Wiring

Bus cable, cable length and size

To connect the equipment use the supplied M12 connecting sockets.

Note that screened multi-cored twisted-pair control cable is required as Bus line, e. g. UNITRONIC® BUS CAN 2 x 2 x ...mm² or RE-2YCYV-fl 2 x 2 x ...mm².

Control cable assemblies (cable with plug and connector) of various lengths are available as add-on equipment.

The cable length dictates the baud rate (data transfer rate) between the bus nodes, and the total power consumption of the sensor dictates the conductor size.

Attention

Wire equipment in series. Star-type wiring is not permitted!

Connect screens of the bus cables once to the central earthing point (CEP).

If two or more system components are connected in a CAN bus system, the first and the last device must be provided with a terminating resistor of 120 Ω (terminal

CL/CH). We recommend that you use the URB 2 with a connecting socket equipped with ­terminating resistor either as first or as last device.

Only one operating and display unit URB 2 may be used per CAN bus network.

The CAN bus system must not be interrupted during operation.

In the event of an interruption a malfunction alarm is raised.

The operating and display unit URB 2 must not be applied in parallel with the operating, display & automatic control device SPECTORcontrol.

The display field changes its appearance according to the indicated menu. The symbol bar shows the available functions of the activated menu.

The operating bar consists of four pushbuttons and a navigation wheel. The symbol bar indicates the functions assigned to the pushbuttons and the control of the navigation wheel.

Attention

Do not press several pushbuttons at the same time or when using the navigation wheel. Incorrect data input may occur.

To ensure correct entries press the respective pushbutton or use the navigation wheel for one second.

Specification of keys and navigation wheel

The functions allocated to the keys and the navigation wheel of the operating and display unit URB 2 depend on the activated menu. The allocation is shown in the symbol bar.

Press key to view the associated help text in a separate menu window. Press button to confirm the parameter settings.

Press button for approx. 1 sec to confirm the parameter settings of values or devices. If only one value can be changed in the menu the indicator in the parameterisation mode will go to the value to be set.

Turn the navigation wheel to the left or to the right to select menus, devices or parameter settings. In addition, if the symbol is shown, you can confirm this selection by pressing the navigation wheel.

To make larger modifications of the entered data more quickly use keys and for a fairly rough selection. Then use these keys or the navigation wheel for the subsequent fine tuning.

To activate the manual mode of the individual devices use key . The equipment will be controlled only by the operating and display unit URB 2 unless it is deactivated. The manual mode is indicated in the indicating bar of the start menu by the symbol .

The activation or deactivation of the password protection is indicated in the symbol bar of the start window by or .

The key has several functions. When the parameterisation mode is active it can be used to cancel the current modifications and to go back to the original setting. Furthermore it closes the active ­submenu and opens the master menu. To return to the start menu press the key several times.
