Product description It functions even when exposed to strong external vibration or changing products. Solid detection in water If OPTISWITCH 3100 C was ordered for detection of solids in water, the tuning fork is adjusted to the density of water. In the air or when covered by water (density: 1 g/cm³/0.036 lbs/in) OPTISWITCH 3100 C signals "uncovered". Only if the vibrating element is also covered with solids (e.g. sand, sludge, gravel etc.) will the sensor signal "covered".
Product description 3.4 Storage and transport Packaging Your instrument was protected by packaging during transport. Its capacity to handle normal loads during transport is assured by a test according to DIN 55439. The packaging of standard instruments consists of environment-friendly, recyclable cardboard. In addition, the sensor is provided with a protective cover of cardboard. For special versions PE foam or PE foil is also used. Dispose of the packaging material via specialised recycling companies.
Mounting 4 Mounting 4.1 General instructions Switching point In general, OPTISWITCH 3100 C can be mounted in any position. The instrument must be mounted in such a way that the vibrating element is at the height of the requested switching point. Moisture Use the recommended cables (see chapter "Connecting to power supply") and tighten the cable gland.
Mounting Handling The vibrating level switch is a measuring instrument and must be treated accordingly. Bending the vibrating element will destroy the instrument. Warning: The housing must not be used to screw in the instrument! Applying tightening force on the housing can damage its internal mechanical parts. To screw in, use the hexagon above the thread. 4.2 Mounting instructions Socket The vibrating element should protrude into the vessel to avoid buildup.
Mounting In abrasive solids, mounting according to illustration b. has proven. A spout forms in the concave protective sheet preventing wear of the protective sheet. Horizontal mounting To achieve a very precise switching point, you can install OPTISWITCH 3100 C horizontally. However, if the switching point can have a tolerance of a few centimeters, we recommend mounting OPTISWITCH 3100 C approx. 20° inclined to the vessel bottom to avoid buildup. a. b. 20° Fig.
Mounting 1 2 Fig. 5: Orientation of the tuning fork in case of flow 1 Marking with screwed version 2 Direction of flow Adhesive products In case of horizontal mounting in adhesive products, the surfaces of the tuning fork should be vertical in order to reduce buildup on the blades. On the screwed version you will find a marking on the hexagon. With this, you can check the position of the tuning fork when screwing it in. When the hexagon touches the seal, the thread can be still turned by approx.

Maintenance and fault rectification 7 Maintenance and fault rectification 7.1 Maintenance When used as directed in normal operation, OPTISWITCH 3100 C is completely maintenance free. 7.2 Rectify faults Causes of malfunction OPTISWITCH 3100 C offers maximum reliability. Nevertheless faults can occur during operation. These may be caused by the following, e.g.: l l l l Sensor Process Power supply Signal processing Fault rectification The first measure to be taken is to check the output signal.
Maintenance and fault rectification l Wrong mode selected à Set the mode switch on OPTISWITCH 3100 C to "max". Set the correct mode on the signal conditioning instrument (A: overfill protection; B: dry run protection). ? Signal lamp flashes red l Electronics has detected a failure à Exchange instrument or return instrument for repair 7.3 Exchange the electronics In general, all oscillators of series WE60 can be interchanged.
Maintenance and fault rectification 6 Remove the old oscillator 7 Compare the new oscillator with the old one. The type label of the oscillator must correspond to that of the old oscillator. This applies particularly to instruments used in hazardous areas. 8 Compare the settings of the two oscillators. Set the adjustment elements of the new oscillator to the same setting of the old one. Information: Make sure that the housing is not rotated during the electronics exchange.
Dismounting 8 Dismounting 8.1 Dismounting procedure Warning: Before dismounting, be aware of dangerous process conditions such as e.g. pressure in the vessel, high temperatures, corrosive or toxic products etc. Take note of chapters "Mounting" and "Connecting to power supply" and carry out the listed steps in reverse order. With Ex instruments, the housing cover may only be opened if there is no explosive atmosphere present. 8.
