Return Procedure - Siemens SITRANS P500 Kompaktbetriebsanleitung

You can backup application-specific data before changing the measuring cell and reload them afterwards. Use an input
device which supports the HART protocol. (e.g. HART communicator, PC with HART modem and HART software or PC with
HART modem and PDM software). Factory settings will be used if application-specific data are not backed up before the
measuring cell is changed.
Technical developments enable advanced functions to be implemented in the firmware of the measuring cell or application
electronics. Further technical developments are indicated by modified firmware statuses (FW). The firmware status does not
affect whether the modules can be replaced. However, the scope of functions is limited to the function of existing
components.
If a combination of certain firmware versions of measuring cell and application electronics is not possible for technical
reasons, the device will identify this problem and go into "Fault current" mode. This information is provided via the HART
interface.
6.3 Cleaning
WARNING
Dust layers above 5 mm
Danger of explosion in hazardous areas. Device may overheat du to dust build up.
● Remove any dust layers in excess of 5 mm.
NOTICE
Penetration of moisture into the device
Device damage.
● Make sure when carrying out cleaning and maintenance work that no moisture penetrates the inside of the device.
Cleaning the enclosure
● Clean the outside of the enclosure and the display window using a cloth moistened with water or a mild detergent.
● Do not use aggressive cleaning agents or solvents. Plastic components or painted surfaces could be damaged.
WARNING
Electrostatic charge
Danger of explosion in hazardous areas if electrostatic charges develop, for example, when cleaning plastic enclosures
with a dry cloth.
● Prevent electrostatic charging in hazardous areas.
6.3.1 Servicing the remote seal measuring system
The remote seal measuring system usually does not need servicing.
If the mediums are contaminated, viscous or crystallized, it could be necessary to clean the diaphragm from time to time.
Use only a soft brush and a suitable solvent to remove the deposits from the diaphragm. Do not use corrosive cleaning
agents. Prevent the diaphragm from getting damaged due to sharp-edged tools.
NOTICE
Improper cleaning of diaphragm
Device damage. The diaphragm can be damaged.
● Do not use sharp or hard objects to clean the diaphragm.
6.4

Return procedure

Enclose the bill of lading, return document and decontamination certificate in a clear plastic pouch and attach it firmly to the
outside of the packaging. Any devices/replacement parts which are returned without a decontamination declaration will be
cleaned at your expense before further processing. For further details refer to the operating instructions.
