Gruppe D Display shows . . . Cause Remedial action
D 1 Line Int. Power failure.
Note: no counting during
power failure. Delete error message in
RESET/QUIT. menu. Reset
totalizer(s) if need be.
D 2 I Overrange Current output overranged.
(Flow > measuring range) Check instrument parameters and
correct if necessary. Error message
deleted automatically after cause
has been eliminated.
D 3 P Overrange Pulse output overranged.
Note: totalizer deviation
possible
(Flow > I Max) Check instrument parameters,
correct if necessary, and reset
totalizer(s). Error message deleted
automatically after cause has been
eliminated.
D 4 Totalizer Counts lost
(overflow, data error) Delete error message in
RESET/QUIT. menu.
D 5 ADC Analog/digital converter
overranged. Error message deleted
automatically after cause has been
eliminated.
D 6 Fatal Error Fatal-Error, all outputs set to
“min.” values. Replace signal converter
(see Sect. 8.3) or contact KROHNE
Service, having first noted down
hardware information and error
status, see Fct. 2.02.
D 7 Startup
cyclic flashing Hardware fault,
Watchdog activated. Replace signal converter
(see Sect. 8.3) or contact
KROHNE Service.
D 8 Pipe empty The measuring tube is empty.
This message appears only when
the Option ”empty pipe
identifier“ is built in and when the
function is switched on under Fct.
3.06 Application, submenu
“empty pipe“. Fill the pipe.
D 9 Unsteady display – Process product
conductivity too low,
particles/air inclusions too large
or inhomogeneous
– Pulsating flow
– Time constant too low or
switched off.
Increase time constant,
see Fct. 1.02, or switch on.
Power supply OFF Power supply ON D 10 No display
Check power fuse F5. Replace if defective
(see Sect. 8.2).
Group I Fault / Symptom Cause Remedial action
Incorrect connection/polarity Connect properly, see Sect. 2.4.
Receiver instrument or
current output defective. Check output (see Sect. 7.2) with
new milliammeter: Test ok,
check connection cables and
receiver instrument, replace if
necessary. Test unsuccessfully,
current output defective. Replace
signal converter (see Sect. 8.3) or
contact KROHNE Service
Current output disabled,
see Fct. 1.05 Activate under Fct. 1.05.
Short-circuit between current
output and pulse output. Check connection and cables,
see Sect. 2.4. Voltage between
I+ and I
⊥ (connecting block XC
Pins d16 and z18), approx. 24 V.
Switch off device, eliminate short-
circuit, and switch device on again.
I 1 Receiver instrument
indicates “0”.
External voltage source defective Check power lines and/or external
voltage source, and replace if
necessary.
