RENNERtronic: The user-friendly basic control

Performance features

Pressure control within two adjustable pressure bands:
Customers can determine two pressure bands within limits set by the factory. Based on these pressure bands the compressor is controlled.

Monitoring of adjustable maintenance intervals:
For different compressor components, such as air or oil filters, maintenance intervals can be programmed. A message appears when maintenance is due.

Fault memory:
The last ten messages stating the current operating hours are displayed on the control for diagnostic purposes.


Different code levels:
The menu system is protected from unauthorised changes by various code numbers (e.g. factory code, service code, customer code).


Base load change over function:
The control has a base load change over function that can be activated via the menu (additional module required).


Control of frequency converters: A PI control is integrated for controlling compressors with variable speed control. This control determines the rotating speed setpoint depending on the set pressure limit and transmits this to the converter as an analog signal (additional module).


Modbus RTU:
Serves, for instance, for the connection to a higherlevel control system or a building control system (Industry 4.0 Ready).
