501 S: SW.-UPDATE ACT.
!: # 501 0x48
0x49
0x4A
UNCERTAIN Substitute set
(Substitute set
of failsafe
status)
O.K.
Low
High
New amplifier
software loaded Cause:
New amplifier or communication software version
is loaded.
Currently no other functions are possible.
Remedy:
Wait until process is finished. The device will
restart automatically.
502 S: UP-/DOWNLO. ACT.
!: # 502 0x48
0x49
0x4A
UNCERTAIN Substitute set
(Substitute set
of failsafe
status)
O.K.
Low
High
Upload/download
of device data
active Cause:
Up- or downloading the device data via operating
program. Currently no other functions are possible.
Remedy:
Wait until process is finished.
586 P: OSC. AMP. LIMIT
$: # 586 0x10
0x11
0x12 BAD Sensor Failure O.K.
Low
High
Oscillation
amplitude too low Cause:
The fluid properties do not allow a continuation of
the measurement.
Causes:
Extremely high viscosity
Fluid is very inhomogeneous (gas or solid content)
Remedy:
Change or improve process conditions.
587 P: TUBE NOT OSC
$: # 587 0x10
0x11
0x12 BAD Sensor Failure O.K.
Low
High
No oscillation
possible Cause:
Extreme process conditions exist. The measuring
system can therefore not be started.
Remedy:
Change or improve process conditions.
588 P: GAIN RED.IMPOS
$: # 588 0x10
0x11
0x12 BAD Sensor Failure O.K.
Low
High
Gain reduction
impossible Cause:
Overdriving of the internal analog to digital
converter.
A continuation of the measurement is no longer
possible!
Causes:
Cavitation
Extreme pressure shock
High gas flow velocity
Remedy:
Change or improve process conditions, e.g. by
reducing the flow velocity.
601 S: POS. ZERO-RETURN
!: # 601 0x53 UNCERTAIN Sensor
conversion
not accurate
(measured
value from
sensor not
accurate)
Constant Positive zero return
active Cause:
Positive zero return is active
Remedy:
Switch off positive zero return:
Access:
BASIC FUNCTIONS
→ SYSTEM PARAMETER →
CONFIGURATION
→ POS. ZERO RETURN
( → OFF)
691 S: SIM. FAILSAFE
!: # 691 0x48
0x49
0x4A
UNCERTAIN Substitute set
(Substitute set
of failsafe
status)
O.K.
Low
High
Simulation failsafe
active Cause:
Simulation of response to error is active.
Remedy:
Switch off simulation:
Access:
SUPERVISION
→ SYSTEM → OPERATION →
SIM. FAILSAFE MODE ( → OFF)
No. Device status message
(local display)
PROFIBUS measured value status
Extended
diagnostic
message in the
