4.2.9 Communication
Lost communication
In a network system with custom designed interface modules acting as master on the Modbus, it is
desirable to stop the compressor from running when communication to the master is lost.
If communication is lost it will not be possible for the customer to stop the compressor as long as cool-
ing is requested.
The function will stop the compressor after a certain time,
(Communication time out) when there is no
contact to the master controller. The stop is realized through the MainSwitch . The Main Switch will be
set to OFF. It will remain OFF until the master controller sets it back to ON via Modbus.
Protection of settings
A coded privacy function protects customers’ settings from being read by third parties.
The code must be verified by entering twice.
