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.

URB 2
The operating and display unit URB 2 is designed for installation in control cabinets.
1. Provide cut out in control cabinet, dimensions 174 x 145 mm, max. sheet thickness 10 mm.
2. Unscrew the white fixing nuts
D and remove the back of the housing C. If necessary you can also
unscrew the stud but not more than 35 mm.
3. Put the operating and display unit URB 2
A into the cut-out, replace the back of the housing C,
screw in and tighten the fixing nuts D.

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.
Baud rate Cable length
250 kBit/s 125 m 2 x 2 x 0.34
125 kBit/s 250 m
100 kBit/s 335 m
50 kBit/s 500 m
20 kBit/s 1000 m
10 kBit/s 1000 m
Wiring the connecting sockets
Wire the connecting sockets in accordance with the wiring diagram.

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.

Operator interface
The operating and display unit URB 2 shows parameters, operating conditions and other operating
data. The menus can be selected and all inputs can be made by using the four pushbuttons and the
navigation wheel.
The operator interface of the operating and display unit URB 2 consists of four areas:
Title bar
Display field
Symbol bar
Operating bar
The title bar lists the menus. The selected menu is highlighted by a black background. Due to the
limited space of the display not all menus can be shown.
Note
Current alarm indicators are indicated in the title bar.
The equipment that raised the alarm is flashing.
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.
