During work on and with the device, the required personal protective equipment must always be worn. Appropriate use The VEGACAP 98 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.
That is why we have introduced an environment management system with the goal of continuously improving company environmental pro- tection. The environment management system is certified according to DIN EN ISO 14001. Please help us fulfil this obligation by observing the environmental instructions in this manual: • Chapter " Packaging, transport and storage" • Chapter " Disposal" VEGACAP 98 • Relay (DPDT)
– If necessary, further certificates Information: Optional instrument features are also described in this operating instructions manual. The respective scope of delivery results from the order specification. Constituent parts The VEGACAP 98 consists of the components: • Process fitting with probe • Housing with electronics • Housing lid Fig.
The capacitance change is converted by the electronics module into a switching command. Voltage supply VEGACAP 98 is a compact instrument, i.e. it can be operated without external evaluation system. The integrated electronics evaluates the level signal and outputs a switching signal. With this switching signal, a connected device can be operated directly (e.g.
Technical data - Ambient conditions" • Relative moisture 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. VEGACAP 98 • Relay (DPDT)
Mounting instructions Inflowing medium If the instrument is mounted in the filling stream, unwanted false measurement signals can be generated. For this reason, mount the instrument at a position in the vessel where no disturbances, e.g. from filling openings, agitators, etc., can occur. VEGACAP 98 • Relay (DPDT)
Wiring plan - single chamber housing Wiring plan We recommend connecting VEGACAP 98 in such a way that the switching circuit is open when there is a level signal, line break or failure (safe state).

Inductive loads also result from the connection to a PLC input or output and/or in combination with long cables. It is imperative that you take measures to extinguish sparks to protect the relay contact (e.g. Z diode) or use an electronic version with transistor output. VEGACAP 98 • Relay (DPDT)
Note: As a rule, always set the mode with the mode switch (5) before start- ing setup VEGACAP 98. The switching output will change if you set the mode switch (5) afterwards. This could possibly trigger other con- nected instruments or devices.

The measuring system is immediately ready for operation. ment The switching point must no longer be set with VEGACAP 98. The probe has an active tip and a screen segment. Thanks to the screen segment, the so called standing capacitance, caused by the vessel after installation of the probe, is mainly compensated.

Remove the electronics module. Check the resistance between the the probe two plug connections. There must no longer be a connection (high impedance). If there is still a connection, exchange the instrument or return it for repair VEGACAP 98 • Relay (DPDT)

In both cases, the probe must be repaired in our premises. Contact 4 against vessel The electrical connection between contact 4 and metal vessel (not the mounting boss or probe flange) should good. Measure the resist- ance value between contact 4 and vessel with an ohmmeter (range very small). • Shortcircuit (0 … 3 Ω) - optimum connection • Resistor > 3 Ω - bad connection VEGACAP 98 • Relay (DPDT)
3. Remove the housing cover 4. Loosen the screws of the terminals with a Allen wrench. 5. Pull the connection cables out of the terminals. 6. Loosen the two screws with a Torx screwdriver. VEGACAP 98 • Relay (DPDT)
Clean the instrument and pack it damage-proof • Attach the completed form and, if need be, also a safety data sheet outside on the packaging • Ask the agency serving you to get the address for the return ship- ment. You can find the agency on our homepage. VEGACAP 98 • Relay (DPDT)
