System Description
The URB 1 is a user-friendly control terminal and display
unit for use with GESTRA CAN bus systems. With the URB 1
all standard functions of the CAN bus systems can be easily
called up and adjusted. The URB 1 uses the CANopen protocol.
Furthermore, the URB 1 makes the parameterization of the
controller very convenient: The switchpoints, the response
sensitivity and the proportional band can be adjusted by
means of the keypad regardless of the actual values (level,
conductivity). The energizing and deenergizing times of the
relays can be customized for the switchpoints.The URB 1 features a continuous display and therefore
meets the requirements of TRD 401 / EN 12952 and
EN 12953 for a second water level indicator. The equip-ment
has also a temperature-compensated conductivity indication
as required by VdTÜV – Bulletin WÜ 100 (Water Level 100).
The equipment indicates also malfunctions such as
faulty electrode, excessively high temperature in a sensor, ambient temperature above max. limit, faulty communication etc.
The following tables specify the GESTRA equipment that can
be displayed by the URB 1:
