OPERATIONAL SAFETY
ThetransducermeetstherequirementsofEN61010-1standard
intermsofoperationalsafety.
Safety precautions:
The assembly and installation of electrical connections must be
carriedoutbyapersonauthorizedtoinstallelectricalequipment.
Beforeswitchingthe transduceron,onemust checkthecorrect-
nessofconnections.
Thedeviceisdestinedtobeinstalledandusedinindustrialelectro-
magneticenvironmentconditions.
The building installation should be equipped with a switch
or an automatic circuit breaker located near the device,
which should be easy accessible by the operator and properly
marked.
Removal of the transducer housing during the  warranty period
maycauseitsinvalidation.

5.2. Messages after switching on the power
After connecting external signals and switch the power supply
on which is signalled with a green LED (power indicator), the transdu-
cer displays the type, current firmware version and the serial number.
If the transducer is equipped with Ethernet interface (P30U-X2XXXXXX)
IP address is displayed after serial number (stored in memory or recei-
ved from the DHCP server).

5.4. Programming transducer parameters
 Press and hold for about 3 seconds key
to enter the programming matrix. If access is password protected,
transducer will ask for password. If the entered password is incorrect,
Err.Code message will be displayed. Correct password enables
access to the programming matrix. Fig. 8 shows the matrix
in the programming mode. Use or to select
the menu level or navigate the parameters of a given sub-level.
The parameter symbol is displayed at the upper line of the display,
while the parameter is displayed at the lower line of the display.
Press to edit parameter. Press to cancel changing
parameter. Press and hold to exit the programming matrix
and enter the measurement mode. If the transducer remains inactive
for 30 seconds in the parameter programming mode, it will exit the pro-
gramming mode and display the displayed value.
