Important Notes
Usage for the intended purpose
Use operating terminal & display unit URB 1 only in conjunction with GESTRA Spector Bus systems
(CANopen).
Safety note
The equipment must only be installed and commissioned by qualified and competent staff. Retrofit-
ting and maintenance work must only be performed by qualified staff who – through adequate training
– have achieved a recognised level of competence.
The equipment meets the requirements of the Low Voltage Directive 2014/35/EU.
Attention
The name plate specifies the technical features of the equipment. Note that any piece of
equipment without its specific name plate must neither be commissioned nor operated.
LV (Low Voltage) Directive
According to the European Directive 2014/34/EU the equipment must not be used in potentially explo-
sive areas.
ATEX (Atmosphère Explosible)
The equipment meets the requirements of the EMC Directive 2014/30/EU.
EMC (Electromagnetic Compatibility)

Description
The URB 1 is a user-friendly operating terminal and display unit for GESTRA CAN bus systems.
The equipment makes retrieving and processing all standard functions of associated system
components very easy. The URB 1 uses the CANopen protocol. 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 list the GESTRA systems that can be viewed by the URB 1.

Enclosure of insulating material with terminals for installation in control cabinets.
The terminals are accessible from the back.
External dimensions: 95 x 95 x 63
Function
The URB 1 communicates with other GESTRA system components via 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.
