The URB 1 is a user-friendly operating terminal and display unit for GESTRA CAN
bus systems using the CANopen protocol.The equipment makes retrieving and
processing standard functions of associated system components very easy.
In addition, the URB 1 simplifies the parameterisation procedure: The switchpoints,
proportional band and response sensitivity can be adjusted by means of the keypad
regardless of the actual level. The energizing and de-energizing times of the relays
can be set individually for their respective switchpoints.
The following tables specifiy the GESTRA systems that can be displayed by the
URB 1.
Important Notes
Safety Note
Use operating terminal and display unit URB 1 only for operating and viewing
GESTRA CAN bus systems.
The equipment must only be installed by qualified staff.
Qualified staff are those persons who – through adequate training in electrical
engineering, the use and application of safety equipment in accordance with
regulations concerning electrical safety systems, and first aid & accident prevention –
have achieved a recognised level of competence appropriate to the installation and
commissioning of this device.
Usage for the intended purpose
Use operating terminal & display unit URB 1 only in conjunction with GESTRA
Spector bus systems (CANopen).

■Wire equipment in series. Star-type wiring is not permitted.
■Interlink screens of control cables such that electrical continuity is
ensured and connect them once to the central earthing point (CEP).
■If more than one system component is connected to a CAN bus
network provide the first and last equipment with a terminating resistor
of 120 Ω, Fig. 2
■The CAN bus line must not be interrupted while operating with one or
more system components.
Any interruption will open the control circuit!
If the switching controller has to be replaced be sure to remove first
the terminal strips , Fig. 4
Note: Make sure that all system components connected are
not
operating
before removing the CAN bus line from the terminal strip!

Attention
Note that multi-core control cable with conductors linked in pairs, e. g. UNITRONIC®
BUS CAN 2 x 2 x .. mm2or RE-2YCYV-fl 2 x 2 x .. mm2.
The baud rate (data transfer rate) dictates the cable length between the bus nodes
and the total power consumption of the sensors dictates the conductor size.

The baud rate is set via a code switch. Reduce baud rate if cable is longer than
specified in the table above. Make sure that all bus nodes feature the same settings.
To protect the switching contacts fuse circuit with 2.5 A (anti-surge fuse) or according
to TRD regulations (1.0 A for 72 hrs operation).
When a max. cable length of more than 125 m (up to 1000 m) is desired, make
sure to modify the baud rate accordingly. Refer to pages 75 and 76 for more
details.

Note
■Connect screen only to terminal 3, ensuring electrical continuity and
connect equipment once to the central earthing point (CEP).
■The loop resistance must be under 10 Ω.
■The rated voltage is stated on the name plate.
■Despite correct wiring H.F. interference caused by the installation may
lead to system breakdowns and malfunction messages. If necessary
refer to the fault finding lists of the respective bus equipment.

Basic Settings
CAN-Bus
All level and conductivity controllers and associated electrodes are interconnected by
means of a CAN bus using the CANopen protocol. Every item of equipment features
an electronic address (node ID). The four-core bus cable serves as power supply and
data highway for high-speed data exchange.
The CAN address (node ID) can be set between 60 and 123.
The URB 1 is configured at our works and ready for service with other GESTRA
system components without having to set the node ID.
If several systems of the same kind are to communicate in one CAN bus
network, be sure to assign one node ID for each individual system component
(e. g. controller). Refer to page 75 and 76 for more information.
Factory set default values
The URB 1 features the following factory default settings:
■Baud rate: 250 kb/s
■Node ID: 060 (Do not change this node ID unless required; highest permissible
setting: 123)

Changing factory set node ID of the URB 1 / Adjusting & changing node ID
The factory set node ID of the URB 1 is
“060”. Node IDs below this value are
reserved for other GESTRA bus
components.
If additional operating terminals type URB 1
are used in a CAN bus system, you have to
set their node IDs to values above “060”.
Note that the newly established node IDs
must not be identical with node IDs of other
bus components.
Press and hold button for a few
seconds to enter the address
parameterisation mode.

Possibilities to display bus devices
The URB 1 can display only one level monitoring device, one low-level alarm, one
high-level alarm and one conductivity monitoring device per vessel (e. g. steam
boiler or feedwater deaerator).
If the monitoring systems of more than one vessel are to be displayed, provide one
URB 1 per vessel.
Press button briefly to activate the line

In our example the node ID was set to
“061”.

Setting /changing node IDs of bus-based equipment
The standard default node ID setting of all
bus devices that can be displayed is “OFF”.
This setting acts as a wild card for all bus
devices which are not displayed with the
URB 1.
For each bus device that shall be displayed
by the URB 1 a node ID has to be
established manually.
We recommend to accept the factory set
node IDs of GESTRA bus devices. For the
relevant node ID setting please refer to the
corresponding installation manual of the
device.
