CAN
A CAN network is of multi drop type which means that all units are connected in parallel on the
same cable. In a CAN network every unit must have a unique address or ID-number.
On the CA 44x series one part of the address is set default depending on type of device, the other
part of the address is set by a hexadecimal switch, marked "ID". Choose address by pump number
as in table below. If the device has a unique address and contact with the network master, the CAN
LED is still fixed green. For error codes of the CAN LED see PC 441 User guide.
Use the following addresses to achieve correct functions.
