Instructions On Commissioning - Siemens SITRANS P500 Compact Operating Instructions

WARNING
Intrinsically safe circuits
With intrinsically safe circuits, use only certified ammeters appropriate for the transmitter.
"Intrinsically safe"
If a non-conforming supply unit is used, the "fail-safe" type of protection will no longer be effective and the approval
certification will be invalid.

Instructions on commissioning

Note
To obtain stable measured values, the transmitter needs to be allowed to warm up for five minutes or so after the supply
voltage is switched on.
The operating data must correspond to the values specified on the nameplate. If you switch on the auxiliary power, the
transmitter operates.
The following commissioning cases are typical examples. Depending on the system configuration, configurations different
from those listed here may be useful.
Following commissioning, the transmitter is immediately ready for use.
The adjustable measuring span corresponds to the information on the nameplate. If the device is factory-set to user-specific
values, the start of scale value and full scale value are stated on the tag plate.
If need be, you can change the parameters by simple user operations on the device even during commissioning.
Safety notice for maintenance
For all devices
WARNING
This device is designed to operate with high pressure and / or hazardous media. For this reason, repair and maintenance
work performed on this device with connected supply lines can result in the leakage of hazardous substances from these
lines.
Therefore you must ensure that substances cannot leak prior to opening or dismantling the device, e.g. block the line or
separate the line from the device.
WARNING
If you are unable to eliminate faults, place the device out of service and protect it against inadvertent commissioning.
CAUTION
If the membrane of the pressure connection is cleaned with pointed or hard objects, you can destroy the membrane.
Therefore, do not use pointed or hard objects to clean the membrane.
NOTICE
Depending on the use of the device and certain empirical values, determine a maintenance interval for the tests to be
carried out repeatedly.
The maintenance interval is also influenced by the corrosion resistance depending on the site of use.
