13.2 Errors/defects caused by the transmitter
Symptom Possible
reason
Remedy
Power supply voltage too low
Check power supply voltage
(> 14 V DC, < 30 V DC)
Cable resistance too high
Larger cable cross section
Transmitter is defective
Check current output
(see section 14
Self-monitoring
functions
)
Replace transmitter if necessary
Current output does not react
or reacts incorrectly
Upper range value has been
reached
Expand measuring range (channels 5
and 6)
Current output is unsteady
Shield not grounded or
bonding conductor not
connected
Ground cable shield or connect bonding
conductor in cable gland
Display blinks constantly
Power supply voltage too low
Supply voltage must be > 14 V DC at
the terminal
Power supply voltage too low Check supply voltage
Empty display
Transmitter is defective Replace
transmitter
Channel ] shows error
number
see error code table, section 13.2.1
Wrong parameterization (e.g.
wrong unit for temperature
coefficient alpha)
Check the programmed log data and
their signs (equations in section 11
might be helpful)
Wrong density or
concentration is displayed or
temperature is "not"
compensated
Specified measuring range
has been exceeded
Requires new programming data
Air or gas bubble in the liquid
see section 13.1
Errors/defects caused
by the liquid
Transmitter is incorrectly
connected to transducer
Check sensor connections
Defective transducer
Check transducer coils if necessary
(see section 13.3)
No frequency signal or
senseless frequency between
test terminals on display
board
Transmitter is defective Replace
transmitter
Transmitter is incorrectly
connected to transducer
Check Pt1000 connections
Displayed temperature is
wrong
Defective transducer
Check temperature sensor (see section
13.3)
