During work on and with the device, the required personal protective equipment must always be worn. Appropriate use The OPTISWITCH 3300 C is a sensor for point level detection. You can find detailed information about the area of application in chapter " Product description". Operational reliability is ensured only if the instrument is properly used according to the specifications in the operating instructions manual as well as possible supplementary instructions.
The EU conformity declaration can be found on our homepage. SIL conformity OPTISWITCH 3300 C meets the requirements to the functional safety according to IEC 61508. Further information is available in the Safety Manual " OPTISWITCH 3XXX".

3 Product description Principle of operation Application area OPTISWITCH 3300 C is a point level sensor with tuning fork for point level detection. It is designed for industrial use in all areas of process technology and is preferably used for bulk solids.
Technical data - Ambient conditions" • Relative humidity 20 … 85 % Lifting and carrying With instrument weights of more than 18 kg (39.68 lbs) suitable and approved equipment must be used for lifting and carrying. OPTISWITCH 3300 C • Transistor (NPN/PNP)
Switching point In general, OPTISWITCH 3300 C can be installed in any position. The instrument only has to be mounted in such a way that the vibrating element is at the height of the desired switching point.
4 Mounting Fig. 2: Measures against moisture ingress Transport Do not hold OPTISWITCH 3300 C on the vibrating element. Espe- cially with flange and tube versions, the sensor can be damaged by the weight of the instrument. Remove the protective cover just before mounting. Pressure/Vacuum The process fitting must be sealed if there is gauge or low pressure in the vessel. Before use, check if the sealing material is resistant against the measured product and the process temperature.

4 Mounting not use an overly long extension tube for OPTISWITCH 3300 C, but check if you can mount a short level switch on the side of the vessel in horizontal position. Extreme vibration caused by the process or the equipment, e.g. agita- tors or turbulence in the vessel, e.g. by fluidisation, can cause the...

The tuning fork must be mounted in a way that takes the arrangement of the filling and emptying apertures into account. To compensate measurement errors caused by the material cone in cylindrical vessels, the sensor must be mounted at a distance of d/6 from the vessel wall.

Marking with screwed version 2 Direction of flow Baffle protection against In applications such as grit chambers or settling basins for coarse falling rocks sediments, the vibrating element must be protected against damage with a suitable baffle. This baffle must be manufactured by you. > 125 mm (> 5") Fig. 7: Baffle for protection against mechanical damage OPTISWITCH 3300 C • Transistor (NPN/PNP)
Cover all housing openings conforming to standard according to EN 60079-1. Connection procedure With Ex instruments, the housing cover may only be opened if there is no explosive atmosphere present. Proceed as follows: 1. Unscrew the housing lid OPTISWITCH 3300 C • Transistor (NPN/PNP)
10. If necessary, carry out a fresh adjustment 11. Screw the housing lid back on The electrical connection is finished. Wiring plan, single chamber housing The following illustrations apply to the non-Ex as well as to the Ex-d version. OPTISWITCH 3300 C • Transistor (NPN/PNP)

Check the vibrating element and the sensor for buildup ement and remove the buildup if there is any. Wrong mode selected Set the correct mode with the mode switch (overflow protection, dry run protection). Wiring should be carried out according to the closed-circuit principle.

6. Pull out the old electronics module 7. Compare the new electronics module with the old one. The type label of the electronics module must correspond to that of the old electronics module. This applies particularly to instruments used in hazardous areas. OPTISWITCH 3300 C • Transistor (NPN/PNP)
15. Screw the housing lid back on The electronics exchange is now finished. How to proceed if a repair is necessary If it is necessary to repair the instrument, please contact the responsi- ble Krohne agency. OPTISWITCH 3300 C • Transistor (NPN/PNP)
With Ex instruments, the housing cover may only be opened if there is no explosive atmosphere present. Disposal The device is made of recyclable materials. For this reason, it should be disposed of by a specialist recycling company. Observe the ap- plicable national regulations. OPTISWITCH 3300 C • Transistor (NPN/PNP)
