PERATIONAL MODES

The level meters can either work in the "basic" mode that measures the level height (Fig. 17), or in

the "inverse mode" that measures distances (Fig. 18).

(measurement of level height)

ETTING UP

After the level meter has been installed, set it up using the "DOWN" and "UP" buttons (see ﬁ g. 16).

The LED indicator "MENU" indicates the on-going set-up procedure of the level meter. You can

set up the "basic mode", which measures the level height (Fig. 17) and set up the "inverse mode"

to measure distances (Fig. 18).

BASIC MODE :

Low margin (4 mA or 0 V) setting up

The tank ﬁ lls up to the level required

Press the "DOWN" button for at least 2 seconds to activate the set-up mode (the LED indicator

"MENU" blinks slowly). Keep the "DOWN" button pressed for another 3 seconds to directly set the

value to 4 mA (0 V). In this case, item 3 can be omitted.

function

Slow ﬂ ashing (1–2 sec., depends on the measuring interval) – reception of

reﬂ ected signal (echo) from the measured level. Correct function.

Fast blinks – the measured value is in "dead zone" of the level meter, or the

ultrasonic transmitter is polluted.

Dark – the measured value is in "dead zone" of the level meter, or the

ultrasonic transmitter is polluted. Incorrect installation or malfunction.

Slow blinks – signalization setting limit 4 mA (0 V).

Fast blinks – signalization setting limit 20 mA (10 V).
