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).

System description – continued –
The URB 1 communicates with other GESTRA system components via a designated
CAN bus using the CANopen protocol to DIN ISO 11898.
The URB 1 can also be used to operate and display further system components
during operation.
