Page 46: Can-Bus
Additional Information CAN-Bus The CAN bus can be used to connect two or more controllers with each other or with the data logger to exchange data. Controller 1 Controller 2 Controller 3 Datalogger (valgfrit) Controller n 1. The controllers are connected in series with the CAN bus cable (1). 2. - Page 47 Tips & Tricks Instead of setting the flow rate for the system using a flow rate limiter, it is better to adjust the flow rate using the switch on the pump and by means of the “max. speed” setting on the controller (see 6.3.4). This saves electricity! The service values (see 8.) include not only current measurement values and operating states, but also all of the settings for the controller.
