  • Page 4: Introduction

    Application The VF05 two-wire guided microwave level transmitter is used to measure the distance, level, and volume of liquids, solids, and granules. The device can be used in storage and reaction tanks, rigid pipelines of suitable diameter, and level reference vessels. The device is HART capable, it can be programmed using HyView software or PACTWARE.

    EPAIR VF05 does not require maintenance on a regular basis. In some very rare instances, however, the probe may need cleaning to remove deposited material. This must be carried out gently, without damaging the probe. Repairs during or after the warranty period are carried out exclusively at the Manufacturer. The equipment sent back for repair should be cleaned or disinfected by the User.

    4.3. W IRING Wiring in non-explosive environments 1. Take the device’s lid off. 2. Put the cable through the cable gland (½" NPT) to the terminal block. 3. Remove the outer insulation for ~80 mm (~3.15″) from the cable so the wires can be accessed, then strip the wires for 4 mm.

  • Page 12: Bus

    N AND OMMISSIONING The VF05 two-wire device is supplied by HYCONTROL with the technical specifications requested by the customer, so it is ready for operation immediately after installation and wiring up. Measuring starts less than 20 seconds after switching on. Attention! The initial current consumption of the device is 3.5 mA right after switching on! If there is a change in the installation data due to shortening a cable probe, the set parameters must be changed according to the application before starting the measurement.

    The device continues measuring while the menu is accessed. Changes made in the menu take effect when you exit the menu. If you do not exit the VF05 menu, the device will automatically return to the measurement display state after 30 minutes. In this case, any changes made in the menu will be ignored.
