Page 13: Description Of The Backplanes For The Sensor Cubes
Type 8905 Description Description of the backplanes for the sensor cubes Each sensor cube is plugged on a sensor cube backplane. All the backplanes for the sensor cubes have the same design. Thus any sensor cube can be plugged on any sensor cube backplane in the system. The backplanes are connected to each other and feed the sensor cubes with the power supply and the process water. The backplanes are connected in parallel, i.e. if a sensor cube is removed, the other sensor cubes continue measuring. When the sensor cube is removed from its backplane, the interface is tight. A locking pin prevents from unintentional move of the bayonet lever. DANGER Risk of injury due to the nature of the fluid if no sensor cube is plugged on a backplane. If the fluid outlet of the backplane is open, fluid may splash on you. • The fluid outlet must stay closed if the backplane has no sensor cube. • Do not move the bayonet lever with the hand. NOTE The backplane may be damaged if no sensor cube is plugged on a backplane. A short-circuit may damage the backplane if the electrical contacts are touched with a conductive material. ▶ Do not touch the electrical contacts. ▶ Cover the electrical contacts with a correct protection cap: contact the manufacturer.
