Endress+Hauser Micropilot FMR62 - Heartbeat Monitoring

Micropilot FMR62
78 Endress+Hauser
Device functionality checked on demand
• Verification of the correct functioning of the measuring device within specifications.
• The verification result provides information about the condition of the device: Passed or Failed.
• The results are documented in a verification report.
• The automatically generated report supports the obligation to demonstrate compliance with
internal and external regulations, laws and standards.
• Verification is possible without interrupting the process.
Advantages
• No onsite presence is required to use the function.
• The DTM triggers verification in the device and interprets the results. No specific knowledge is
required on the part of the user.
(DTM: Device Type Manager; controls device operation via DeviceCare, FieldCare or a DTM-based
process control system.)
• The verification report can be used to prove quality measures to a third party.
• Heartbeat Verification can replace other maintenance tasks (e.g. periodic check) or extend the
test intervals.
SIL/WHG-locked devices
Only relevant for devices with SIL or WHG approval: order code 590 ("Additional approval"), option
LA ("SIL") or LC ("WHG").
• The Heartbeat Verification module contains a wizard for the proof test which must be performed
at appropriate intervals for the following applications:
• SIL (IEC61508/IEC61511)
• WHG (German Water Resources Act)
• To perform a proof test, the device must be locked (SIL/WHG locking).
• The wizard can be used via FieldCare, DeviceCare or a DTM-based process control system.
In the case of SIL-locked and WHG-locked devices, it is not possible to perform verification
without taking additional measures (e.g. bridging the output current) because the output
current must be simulated (Increased safety mode) or the level must be approached manually
(Expert mode) during subsequent re-locking (SIL/WHG locking).

EH
Heartbeat Verification + Monitoring
Function
• In addition to the verification parameters, the corresponding parameter values are also logged.
• Existing measured variables, such as the echo amplitude, are used in the Foam detection and
Build-up detection wizards.
"Foam detection" wizard
• The Heartbeat Monitoring module contains the Foam detection wizard.
• This wizard is used to configure automatic foam detection, which detects foam on the product
surface on the basis of the reduced signal amplitude. Foam detection can be linked to a switch
output in order to control a sprinkler system, for example, which dissolves the foam.
• This wizard can be used via FieldCare, DeviceCare or a DTM-based process control system.
"Build-up detection" wizard
• The Heartbeat Monitoring module contains the Build-up detection wizard.
• The wizard is used to configure automatic buildup detection, which detects the buildup of deposits
on the antenna on the basis of the increased area of the coupling signal. Buildup detection can be
linked to a switch output in order to control a compressed air system, for example, to clean the
antenna.
• This wizard can be used via FieldCare, DeviceCare or a DTM-based process control system.
