Troubleshooting
MULTICAL
302 has been constructed with a view to quick and simple installation as well as long and reliable
operation at the heat consumer.
Should you, however, experience an operating problem with the meter, the table below can be used for
troubleshooting.
The meter may only be opened and/or repaired by an authorized laboratory or at Kamstrup A/S.
Before sending us the meter to be repaired or checked, we recommend that you go through the error options listed
below in order to clarify the possible cause of the problem.
Symptom
Possible reason
Proposal for correction
No display function (empty display)
Display is in ”sleep mode”
Press the front button in order to
activate the display.
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 7.8)
If “info” = 2
⇒
Check that the flow direction
matches the arrow on the flow
sensor
If “info” = 4, 8 or 12
⇒
Check temperature sensors. If
defective, replace the meter.
Accumulation of volume (m
3
) but not
of energy (e.g. MWh)
Temperature sensors can be
defective. Check the temperature
sensor cable for visible damage.
Replace the meter
Heat/cooling cutoff
θ
hc
has been
configured too low
(only relevant for meter type 6xx)
Reconfigure
θ
hc
at a suitable value,
or configure
θ
hc
at 180 °C, thereby
disconnecting the cutoff function.
Incorrect temperature reading
Defective temperature sensor
Insufficient installation
Check the installation
Replace the meter
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
Make sure that the sensors have
been pushed to the bottom of the
sensor pockets
Insulate sensor pockets
Replace by longer pockets
