Page 5: Safety
The overfill prevention system NB 220, consisting of a transducer and a level probe, may only be used to avoid overfilling of contain- ers. The overfill prevention system NB 220 is only suitable for operation with stationary containers and stationary-use containers used for the storage of the following liquids. -
Page 6: Predictable Incorrect Application
Any use other than the application explicitly permitted in this instruc- tion manual is not permitted. Predictable incorrect application The overfill prevention system NB 220 must never be used in the fol- lowing cases: • Hazardous area (Ex) and liquids If the device is operated in hazardous areas, sparks may cause deflagrations, fires or explosions. -
Page 7: Modifications To The Product
The manufacturer shall not be liable for misprints. Product description The overfill prevention system NB 220 consists of a level probe and a transducer. The level probe and the transducer are connected by means of a two-wire signal cable. -
