System description

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.

Wiring

Note that multi-core control cable with conductors linked in pairs, e. g. UNITRONIC BUS CAN 2 x 2 x .. mm

or 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.

Wiring diagram

For wiring diagram refer to page 4.

Attention

■ 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

operating

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.

Tools

■ Screwdriver for slotted screws, size 2.5, completely insulated according to

VDE 0680

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.

Node ID for GESTRA bus-based device URB 1

Example: Conductivity monitoring and control

Example: Level monitoring and control

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.

Setting /changing node IDs of bus-based equipment

The standard default node ID setting of all bus devices that can be displayed is “O 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.
