During work on and with the device, the required personal protective equipment must always be worn. Appropriate use VEGAPULS C 23 is a sensor for continuous level measurement. 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.
USA and Canada. Safety instructions for Ex areas For Ex applications, only devices with corresponding Ex approval may be used. Observe the Ex-specific safety instructions. These are an integral part of the operating instructions and are enclosed with every device with Ex approval. VEGAPULS C 23 • Modbus and Levelmaster protocol...
Constituent parts Fig. 1: Components of VEGAPULS C 23 Radar antenna Electronics housing Mounting thread Connection cable Type label You can find the type label on the sensor housing as well as on the type label support on the connection cable.

Principle of operation Application area VEGAPULS C 23 is a radar sensor for continuous level measurement. It is suitable for liquids and solids in virtually all industries, particularly in the water and waste water industry.
Transport Transport must be carried out in due consideration of the notes on the transport packaging. Nonobservance of these instructions can cause damage to the device. VEGAPULS C 23 • Modbus and Levelmaster protocol...
Mounting accessories The mounting accessories include e.g. bracket and mounting bracket and are used for stable mounting of the sensor at the measuring point. The parts are available in various versions and sizes. VEGAPULS C 23 • Modbus and Levelmaster protocol...
Mounting bracket For the wall mounting, a mounting bracket with opening for thread G1½, e.g. from the VEGA product range, is recommended. The mounting of the sensor in the bracket is carried out via a G1½ counter nut of plastic. Take note of chapter "Mounting instructions" for the recommended distance to the wall.

Fig. 11: Recommended socket mounting of VEGAPULS C 23 If the reflective properties of the medium are good, you can mount VEGAPULS C 23 on sockets longer than the antenna. The socket end should be smooth and burr-free, if possible also rounded. Note: When mounting on longer sockets, we recommend carrying out a false signal suppression (see chapter "Parameter adjustment").

This ensures that the interfering reflections from the agitators are saved with the blades in different positions.

Older systems do not always have an integrated Bluetooth LE. In these cases, a Bluetooth USB adapter is required. Activate the Bluetooth USB adapter via the VEGA project assistant (see supplementary instructions "Bluetooth USB adapter"). After activating the integrated Bluetooth or the Bluetooth USB adapt- er, devices with Bluetooth are found and created in the project tree.

• Checking the output signal • Treatment of measurement errors A smartphone/tablet with the VEGA Tools app or a PC/notebook with the software PACTware and the suitable DTM offer you further com- prehensive diagnostic possibilities. In many cases, the causes can be determined in this way and the faults eliminated.
This status message is inactive by default. Maintenance: Due to external influences, the instrument function is limited. The measurement is affected, but the measured value is still valid. Plan in maintenance for the instrument because a failure is expected in the near future (e.g. due to buildup). This status message is inactive by default.
