Maintenance and repair work

6.2.1 Defining the maintenance interval
WARNING
No maintenance interval has been defined
Device failure, device damage, and risk of injury.
Define a maintenance interval for regular tests in line with device use and empirical values.
•
The maintenance interval will vary from site to site depending on corrosion resistance.
•
6.2.2 Checking the gaskets
Inspect the seals at regular intervals
Note
Incorrect seal changes
Incorrect measured values will be displayed. Changing the seals in a process flange of a differential pressure measuring cell
can alter the start-of-scale value.
The seals in devices with differential pressure measuring cells are not designed to be changed.
•
1. Clean the enclosure and seals.
2. Check the enclosure and seals for cracks and damage.
3. Grease the seals if necessary.
6.2.3 Display in case of a fault
Check the start of scale value of the device from time to time.
Differentiate between the following in case of a fault:
● The internal self test has detected a fault, e.g. sensor break, hardware fault/Firmware fault.
Displays:
– Display: "ERROR" display and ticker with an error text
– Analog output: Factory setting: Failure current 3.6 or 22.8 mA
Or depending on the parameterization
– HART: detailed error breakdown for display in the HART communicator or SIMATIC PDM
● Grave hardware faults, the processor is not functioning.
Displays:
– Display: no defined display
– Analog output: failure current < 3.6 mA
In the event of a defect, you can replace the application electronics by following the warning notes and the provided
operating instructions.
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.
