The level meter UltraPro 1000 is equipped with protection against reverse polarity and output
current overload.
Protection against dangerous contact is secured by low safety voltage that complies with
EN 33 2000-4-41.
Electromagnetic compatibility according to EN 55022/B, EN 61326/Z1 and EN 61000-4-2 to 6.
Explosion proof of ULM–70Xi type complies with the following standards: EN 60079-0 : 2007;
EN 60079-11 : 2007 ; EN 60079-26 : 2007 and examined by FTZÚ-AO 210 Ostrava - Radvanice
certificate No.: FTZÚ 09 ATEX 0277X.
Special conditions for safe use UPS-1000:
The device is designed for connection to the isolating repeater IRU-420. When the other approved
supply unit is used, whose output parameters satisfy above mentioned output parameters, it is nec-
essary to have a galvanic separation or, if supply unit without galvanic separation is used (Zener
barriers), it is necessary provide potential equalization between sensor and point of barrier earthing.
For application in zone 0 the present explosive atmospheres - mixture of air with flammable gases,
vapour or mists must comply: 0,8 bar < p < 1,1 bar. The device must be installed in such a way, to
prevent mechanical damage of sensor face. It is necessary carried out earthing by screw which is
placed on head of level meter.
The device must be installed in such a way, to prevent mechanical damage
of sensor face.

ManipulaTion anD MainTenance
The level meter does not require any personnel for its operation. Follow-up displaying device is
used to inform the technological entity operating personnel on the measured substance level height
during the operation.
Maintenance of this equipment consists in verification of integrity of the level meter and of the sup-
ply cable. Depending on the character of the substance measured, we recommend to verify at least
once per year the clarity of the ultrasound transducer emitting field and to clean it, respectively. In
case any visible defects are discovered, the manufacturer or reseller of this equipment must be
contacted immediately.
It is forbidden to perform any modifications or interventions into the UPS-1000 level
meter without manufacturer's approval. Potential repairs must be carried out by the
manufacturer or by a manufacturer authorized service organization only.
Installation, commissioning, operation and maintenance of the UPS–1000 level meter has
to be carried out in accordance with this instruction manual; the provisions of
regulations in force regarding the installation of electrical equipment have to be adhered
to.
Installation in areas with potentially explosive atmospheres must be carried out in accordance
with standard EN 60079-14 (Electrical apparatus for explosive gas atmospheres - Part 14:
Electrical installations in hazardous areas other than mines) and respectively in accordance
with other standards that apply to a given area.
The device must be installed to prevent tensile overload rope electrode level meter.
