Warning to proceed strictly in accordance with the information contained in the doc-
umentation in order to ensure the safety and full functionality of the device.
Information particularly useful during installation and operation of the device.
Information on disposal of used equipment.
BASIC REQUIREMENTS AND SAFE USE
The manufacturer will not be liable for damage resulting from incorrect installation,
failure to maintain a suitable technical condition of the device or use of the device
other than for its intended purpose.
Installation should be carried out by qualified staff having the required authorizations
to install electrical and I&C equipment. The installer is responsible for performing
the installation in accordance with manual as well as with the electromagnetic com-
patibility and safety regulations and standards applicable to the type of installation.
In systems with I&C equipment, in case of leakage, there is a danger to staff due to
the medium under pressure. All safety and protection requirements must be ob-
served during installation, operation and inspections.
If a malfunction occurs, the device should be disconnected and handed over to the
manufacturer for repair.
In order to minimize the risk of malfunction and associated risks to staff, the device
is not to be installed or used in particularly unfavourable conditions, where the fol-
lowing hazards occur:
−possible mechanical impacts, excessive shocks and vibration;
−excessive temperature fluctuation;
−water vapour condensation, dusting, icing.
Changes made to the manufacturing of products may be introduced before the paper version of the
manual is updated. The up-to-date manuals are available on the manufacturer’s website:

−the protection elements used by the manufacturer to ensure transmitter safety may be
less effective if thedevice is operated in amanner not consistent with its intended purpose;
−before installing or disassembling the device, it is absolutely necessary to disconnect
it from the power source;
−no repairs or alterations to the transmitter electronic system are permitted. Assessment of
damages and possible repair may only be performed by the manufacturer or authorized
representative;
−do not use instruments if damaged. In case of malfunction, the device must be put out of
operation.

6. INSTALLATION AND CONNECTION
6.1. General recommendation
Run the signal line "twisted pair" or "twisted pair shielded" in case of high electromagnetic interference.
Avoid running near power cables and large power consumers.
The equipment used with the transmitters should be resistant to electromagnetic interference from the
transmission line in accordance with compatibility requirements.
6.2. Connection with PD connector
Loosen the screw at the top of the connector and the nut connecting the connection to the transmitter
casing, the cable outlet can be set in any direction. It is advantageous to form the cable in the form
of an eave loop in order to prevent the condensate from flowing towards the gland. Connect the wires
according to the marking on the transmitter and Table 2 (depending on the version). A correctly assem-
bled PD connection should have the following tightened: the gland nut, the nut of the connection to the
steel case and the screw connecting both parts of the connection.

6.3. Earthing
Transmitters with PD connections have a ground terminal in the connector, which should not be used
to realise protective earthing or to connect an equalising cable, it is only used for functional earthing.

7. POWER SUPPLY
Table 3. Transmitter supply voltage.
8…39 V DC
Output signal 4…20 mA
2 wires
13…30 V DC
Output signal 0…10 V DC
3 wires
where:
Usup - voltage at the supply terminals of the 4…20 mA current loop [V].
Umin - minimum supply voltage of transmitter.
RLmax - maximum power supply line resistance [Ω].
8. OPERATION
Protect the transmitter against mechanical damage and flooding.
Do not allow any sludge to form on the membrane. Carry out regular inspections.
Temperature range of measuring medium:
•-25 ÷ 130ºC –direct measurement for version without of radiator (M, G1/2);
•-25 ÷ 170ºC –measurement for version with radiator (RM, RG).
Isolation test voltage 110 V DC.
8.1. Setting of measurement range width and “zero” point
Unscrew the electrical connection to access the potentiometer knobs. Connect and power the transmit-
ter according to the technical data. Apply a pressure equal to the lower limit of the measuring range
and bring the output signal to 4 mA (0 V) by turning the "zero" potentiometer knob (turning it clockwise
increases the output signal). After zeroing, set the pressure equal to the upper range limit and use the
"range" potentiometer to bring the output current (voltage) to 20 mA (10 V). Check "zero" again and
repeat the setting if necessary.
Attention:
The user, by means of potentiometers, has the possibility to adjust the "zero" and the range within the
limits up to ±10%.
For transmitters with output signal 0...10 V the "zero" should be set to 0.05 V (transmitters do not reach
0 V).
9. MAINTENANCE
9.1. Periodic inspections
Periodic inspections should be carried out in accordance with thestandards binding for the user. During
the inspection it is necessary to check the condition of pressure connections (absence of looseningand
leakage) and electrical connections (checking the reliability of connections and the condition of seals
and glands).
9.2. Cleaning, washing
In order to remove dirt from the external surfaces of the transmitter, wipe them with In order to re-move
dirt from the external surfaces of the transmitter, they should be wiped with a cloth dampened in water.

Revision 01.A.001/2021.11 9
9.2.1. Diaphragm cleaning
The only possible method of cleaning the transmitter membranes is to dissolve the sludge produced.
Do not remove deposits and impurities from the transmitter diaphragms, which are formed
during operation, mechanically using tools, since the diaphragms and the transmitter can
be damaged.
9.3. Repair
Faulty or non-operational transmitter shall be provided to the manufacturer or an authorized representa-
tive.
9.4. Returns
In the following cases, the transmitter should be returned directly to the manufacturer:
- need for repair;
- need for factory calibration;
- replacement of improperly selected/shipped transmitter.
10. SCRAPPING, DISPOSAL
Worn or damaged devices shall be scrapped in accordance with WEEE Directive
(2012/19/EU) on waste electrical and electronic equipment or returned to the manufactur-
er.
