Group D Display shows . . . Cause Remedial action
D 1 LINE INT. Power failure. Delete error message in
Note: no counting during RESET/QUIT. menu. Reset
power failure. totalizer(s) if need be.
D 2 CUR.OUTP. I Current output overranged. Check instrument parameters
and correct if necessary.
Error message deleted
automatically after cause
has been eliminated.
D 3 PULS.OUTP. P Pulse output overranged. Check instrument parameters,
Note: totalizer deviation correct if necessary, and reset
possible totalizer(s). Error message
deleted automatically
after cause has been
eliminated.
D 4 ADC Analog/digital converter Error message deleted
overranged. automatically after cause
has been eliminated.
D 5 FATAL. ERROR Fatal Error, Replace signal converter
all outputs set to “min.” (see Sect. 8.4) or contact
values. Krohne Service, having
first noted down hardware
information and error status,
see Fct. 2.02.
D 6 TOTALIZER Counts lost Delete error message in
(overflow, data error) RESET/QUIT. menu.
D 7 „STARTUP“ Hardware fault, Replace signal converter
cyclic flashing Watchdog activated. (see Sect. 8.4) or contact
Krohne Service.
D 8 BUSY Displays for flow, Change setting in
totalizers and errors disabled. Fct. 1.04.
D 9 Unsteady display – Process product Increase time constant,
– conductivity too low, see Fct. 1.02, or switch on.
– particles/air inclusions
– too large or inhomogeneous
– Pulsating flow
– Time constant too low or
switched off.
D 10 No display Power OFF. Switch on power
Check power fuse(s) Replace if defective
F1 (F1 and F2 with DC). (see Sect. 8.2).
Group I Fault / Symptom Cause Remedial action
I 1 Receiver instrument Incorrect connection/polarity Connect properly,
indicates “0”. see Sect. 2.4.
Receiver instrument or current Check output (see Sect. 7.2)
output defective. with new milliammeter:
Test ok, check connection
cables and receiver instrument,
replace if necessary.
Test faulty, current output
defective. Replace signal
converter (see Sect. 8.4)
or contact Krohne Service
Current output disabled, Activate under Fct. 1.05.
see Fct. 1.05
Short-circuit between current
Check connection and cables,
output and pulse output. see Sect. 2.4. Voltage between
I+ and I ⊥ approx. 15 V.
Switch off device, eliminate
short-circuit, and switch
device on again.
I 2 Unsteady display – Process product Increase time constant,
– conductivity too low, see Fct. 1.02
– particles/air inclusions
– too large or inhomogeneous
– Pulsating flow
– Time constant too low or
switched off.
