Wiring operations shall only be carried out without voltage!
Taking into account the potential occurrence of electrostatic discharge on non-conducting parts of the level meter, it is necessary to ground
the flange of level meters ULM–53Xi–20–F, located in an explosive atmosphere, using a ground terminal!
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 ČSN 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.
The supply source should be preferably designed as a stabilized source of safe voltage 18 V
to 36 V DC (max. 30 V DC for version Xi), which is part of the downstream processing or display system.
In case of strong ambient electromagnetic disturbance, parallel run of the input cable with the power line or its length exceeding 30 m, we recommend
using a shielded cable.
Set-up elements
Device type with setting using buttons
The measuring range is setup by means of two buttons "DOWN" and
"UP".The "DOWN" button is used to enter to the setting mode (setting
the 4 mA or 0 V limit) and to decrease the output current or voltage.
The "UP" button as an opposite function (setting the 20 mA or 10 V limit
and increasing the output current or voltage). Values are confirmed
by simultaneous pressing of both buttons for about 1 sec. The setting
process is indicated by yellow "STATE" LED indicator.
For detailed information please read at the instructions manual.
Device type with setting using a magnetic pen
The measuring range is setup by touching of the magnetic pen to
sensitive spots "EMPTY" and "FULL" . The "EMPTY" spot is used to
enter to the setting mode (setting the 4 mA or 0 V limit) and to decrease
the output current or voltage. The "FULL" spot as an opposite func-
tion (setting the 20 mA or 10 V limit and increasing the output current
or voltage). Values are confirmed by touching of the magnetic pen to
the sensitive spot for about 3 sec. The setting process is indicated by
yellow "STATE" LED indicator.
For detailed information please read at the instructions manual.

Function
short flashing (repeated depending on the measurement interval approx. 1 ... 2 s) - correct function, receipt of signal (echo)
reflected from the measured surface
fast flashing – the measured surface is in the dead zone of the level meter or the ultrasound transducer is dirty
off – the level meter is not capable of receiving the echo. Incorrect installation or malfunction

slow flashing – 4 mA (0 V) threshold setting indication
fast flashing – 20 mA (10 V) threshold setting indication
3 short flashes – setting confirmation
