URB 60 - Installation & Operating Manual -
819699-00
Function
The URB 60 visual display and operating unit collects the data telegrams in the CAN bus from
GESTRA sensors and control units using the CANopen protocol.
When the system is started, the connected devices are automatically recognised by the URB 60 and
entered in a list of equipment along with all parameters. The groups, their home screens and navigation
buttons are displayed dynamically.
Readings, parameters, settings and messages are shown in plain text. When used as the second water
level indicator in boiler systems (TRD 401, EN 12952/ ...53), the level is also presented as a bar chart.
You can select various languages for the plain text display, see page 27 and 40.
Entering parameters with multilevel password security
Multilevel password security prevents parameters and settings from being changed by unauthorised
persons.
Password level (PWL)
PWL 1 = protected parameter settings
PWL 2 = safety-relevant values can only be set at this level
Operation and configuration, see page 23
The URB 60 is operated and configured on the unit itself using the colour touchscreen or via Ethernet
using remote software.
Limitations
■
■
In the event of signal multiplication, as can occur with a level control system (NRR 2-60 and NRR
2-61), only one level controller can be presented as a bar chart on the home screen.
This is indicated by different graphics in the chart and controller/limiter icons at the bottom of the
screen.
■
■
If the system has more than one STL (safety temperature limiter), the one with the lowest ID is shown
on the home screen.
On the limiter screens, all connected temperature sensors are shown with their actual value and limit
value.
■
■
Switchover between µS and ppm must take place both on the URB 60 and the LRG 1x-6x, so that the
displays match.
