Error message
Cause(s)
Remedy
Number of defective
logs:
The self-monitoring function
of the FCU has detected a
check sum error for one or
more stored logs.
Possible causes
Strong electromagnetic
interference has changed
the measured value
memory.
The internal back-up
battery is dead.
A measurement has been
started and terminated –
for example as a result of
the FCU being switched
off – without any
measured values being
stored.
A measurement
previously conducted
resulted only in a flow
error.
-> The protocol contains
no values.
The defective logs are
deleted automatically.
After the next power up,
this message is not
displayed again if it was
just a brief malfunction.
If this message is displayed
several times, this means
that the internal back-up
battery is probably dead.
Send the FCU to HYDAC
for repair.
No logs stored!
You have tried to print logs,
but the FCU memory is
empty.
Carry out measurements.
Too few points
You have tried to print a
graph, but the selected log
has insufficient
measurement values (min.
3) to produce a graph.
Print out the protocol in the
form of a list.
Battery needs
charging
The rechargeable batteries
are dead.
Measurements are still
possible. However, it is
better to connect a power
adapter, in particular for
printing.
Use power supply
The rechargeable batteries
are dead.
The batteries require a
charging time of ~
11 hours.
You can operate the FCU
using a connected power
supply.
