Warn. Diagnosis
1)
Warning is displayed for 30 seconds.
2)
Transmitter must be equipped with HART communication protocol.
3)
Warning is displayed only if the function is called by an external HART protocol command.
42 - EN
Description
8 If the flow direction is forward,
the warning is displayed in case
of reverse flow.
12 The HART unit address was
changed to an address other
than zero. The current output
remains frozen at 4 mA.
13 Test the current output. Check
the value displayed at the
connection terminals using a
digital voltmeter or the process
instrumentation.
14 Test the pulse output. Check the
value of output frequency with a
counter.
15 Adjustment started for system
zero point adjustment via the
contact input for internal
adjustment (for ABB Service
only).
16 Warning results only when the
"Noise reduction" function is
activated.
17 Diagnosis or wiring warning
Possible cause
Reverse flow
direction, possibly
defective check valve.
Address 1 ... 15
selected. The current
output thereby
remains set at 4 mA.
Function test, enter
current output directly
in mA for simulation.
Simulation pulse
output on.
The external contact
is closed
For ABB Service
personnel only.
Measuring signal
affected by powerful
interference signal.
Min-Max
over/undershoot for
diagnostic values.
Wiring error for
electrode circuit. Coil
short-circuit to ground
FSM4000
Corrective action
Prevent reverse flow or
change flow direction to
forward/reverse.
Select 0 as address, if
the current output
should be 4 ... 20 mA.
Exit the functional test
of current output.
Exit the functional test
of the pulse output.
The external contact is
open again.
For ABB Service
personnel only.
Set noise reduction to
lower level or
deactivate. If
necessary, contact ABB
Service.

register. Adjust the limit
value, if necessary.
