5.1
General information
The FLOWSIC600-XT does not include mechanical moving parts. The meter body and ultra -
sonic transducers are the only components that come into contact with the gaseous
media. Titanium and high-quality steel ensure that these components are resistant to
corrosion, provided that the meter is installed and operated in accordance with the relevant
specifications.
This means that theFLOWSIC600-XT is a low-maintenance system.
User Warning Limits can be configured to provide early warnings for possible issues with
contamination. Maintenance is limited mainly to routine checks to determine the
plausibility of the measured values and diagnostic results produced by the system.
SICK recommends that Maintenance Reports be created and filed on a regular basis
( → p. 101, §5.2.4 ). Over a period of time, this provides a comparison data base useful when
diagnosing problems.
5.2
Routine checks
Proper device function can be determined directly on the front panel of the FLOWSIC600-XT.
The FLOWgate™ operating software provides a user-friendly option for the performance of
routine checks (connect to the device, → p. 86, §4.3.1 ).
5.2.1
Checking the meter state
The FLOWSIC600-XT checks its own meter state with a system of user warnings and
alarms. If the I/O interfaces are configured to indicate alarms and/or user warnings, it is
not necessary to manually check the meter state.
The system status in the FLOWgate
TM
operating software provides a general overview when
a visual feedback on the meter's state is desired.
5.2.1.1
Function check on the display
If there is a warning or malfunction on the device, the corresponding symbol is shown in the
Signal Processing Unit display.
▸
An active error or warning is shown flashing in the LC display. Current errors or warnings
can be retrieved under “Device status” /“Current events” with error code; status
messages see → p. 116, §7.1 .
▸
The status output can be configured to show whether the meter state “Measurement
valid”, “Warning”, “Error”, “Maintenance necessary”, “Backward flow” or status
“Configuration mode” becomes active.
The operating conditions (gas composition, pressure, temperature, flow
velocity) of the individual Maintenance Reports should be similar. When the
individual reports are compared, it is recommended to evaluate and document
deviations.
Table 13 Symbols
Symbol Significance Description
Device status: Malfunction The device has an error, the measured value is invalid.
Device status: Warning The device has a warning, the measured value is still valid.
Registered events Events have occurred since the last event summary reset.
