Page 2: General Precautions
The sensor must be protected against accidental knocks and used in accordance with the instrument’s ambient characteristics and performance levels. Sensors must be powered with non distributed networks. 2. TRANSMITTERS WITH AMPLIFIED DIGITAL OUTPUT Transducers: KMC series Outputs: CANopen (*), J1939, CANopen Safety (*) (*) with CiA 404 Device Profile Installation remarks - The transducer must be grounded (normally through the machine body or equipment it is installed on). -
Page 3: Electrical Connections
Many industrial applications, especially in hydraulics, could present dangerous phenomena like cavitation, liquid hammer or pressure peaks, due for example to pumps The KMC series, upon request, is available with an integrated pressure snubber which, start and stop or fast closing of a valve. -
