Troubleshooting
MULTICAL
801 has been constructed with a view to quick and simple installation as well as long and reliable
operation at the consumer.
Should, however, an operating problem with the meter occur, the table below can be used for troubleshooting.
Repairing the meter, if needed, we recommend only replacing battery, temperature sensors and communication
modules. Alternatively, the whole meter ought to be replaced.
Kamstrup A/S must make major repairs.
Before sending in the sensor for repair or check, please use the error detection table below to help you clarify the
possible cause of the problem.
Symptom
Possible reason
Proposal for correction
No function in the display
(empty display)
Power supply missing
Change backup battery or check
mains supply
No energy accumulation (e.g.
MWh) and volume (m
3
)
Read “info” in the display
Check the error indicated by the
info code (see paragraph 6.8)
If “info” = 000
⇒
Check that the flow direction
matches the arrow on the flow
sensor
If “info” = 004, 008 or 012
⇒
Check the temperature sensors. If
defective, replace the sensor pair.
Accumulation of volume (m
3
),
but not of energy (e.g. MWh)
Inlet and outlet sensors have been
interchanged either in the
installation or at the connection
Mount the sensors correctly
No accumulation of volume (m
3
) No volume pulses
Check that the flow direction
matches the arrow on the flow
sensor
Check the flow sensor’s
connection
Incorrect accumulation of
volume (m
3
)
Erroneous programming
Check that the pulse figure on the
flow sensor matches the calculator
Incorrect temperature reading
Defective temperature sensor
Insufficient installation
Replace the sensor pair
Check the installation
Temperature indication a little
too low, or accumulation of
energy (e.g. MWh) slightly too
low
Bad thermic sensor contact
Heat dissipation
Too short sensor pockets
Place the sensors at the bottom of
the sensor pockets
Insulate the sensor pockets
Replace by longer pockets
