Electrical connection must be done in de-energized state!

With regard to possible occurrence of electrostatic charge on non-conductive parts of the level meter, all level meters for explosive spaces (ULM–70Xi type) must be grounded. It will be done using a screw placed on the head of the level meter under the cable outlet.

The supply voltage source should be preferably realized as a stabilized power supply unit with safe voltage from 18 to 36 V DC (18 ÷ 30 V DC for Xi version), which can be a part of the evaluation or display device.

In case of strong electromagnetic interferences (EMI), parallel cable ducting with power lines, or when cable length exceeds 30 m we recommended to use shielded cable.

It is also necessary to design and take measures to reduce the effects of static electricity to a safe level in the wiring.

Installation in explosive atmospheres needs to be carried out in compliance with CSN EN 60079-14 (Electrical installations for explosive gaseous atmospheres – Part 14: Electrical installations in dangerous areas other than mining) and possibly also in compliance with other standards relating to the area concerned.

If during the scanning of the tank in the bottom of the display appears the dialog "press OK to stop" (see figure) the level meter already found no further obstacles and "TEACHING" mode may be terminated. If it is not terminated, the level meter is still ready for the possible presence of obstacles (e.g. paddles of the agitator). Once it registers a further obstacle, the dialogue disappears and the obstacle is erased. This process may be repeated up to 1000 cycles. After this the "TEACHING" mode is automatically stopped.

The temperature is measured inside the tank where the level meter is installed.If the temperature of the measured medium is different, we recommend you to carry out the temperature compensation "MEDIUM TEM-PERATURE" because of accuracy (see p. 15). Then the displayed temperature is an average value from the temperature set in the "MEDIUM TEMPERATURE" and the actual temperature measured by the sensor.
