Errors, malfunctions and messages
7.1
Recognising errors, correcting
malfunctions
The electronic controller of the ROTEX HPSU monobloc
compact:
– signals an error by means of the background of the display
lighting up red and shows an error code on the display (see
chap. 7.4).
– shows information messages regarding the operating status
(not signalled by red background lighting).
An integrated protocol saves up to 15 error or other operating
status information messages that last occurred.
Depending on the operating mode, messages are also forwarded
to connected room stations or room thermostats.
7.1.1 Current error display
7.1.2 Reading out the protocol
The protocol can be read out in the
"Special Level"
(see fig. 7-3).
The last received (latest) message is in the first position. All other
previous messages are then pushed backwards by one place
when a new entry is made. The 15th message is deleted on ar-
rival of a new message.
7.1.3 Troubleshooting
Information messages that are displayed
without red back-
lighting
normally result in
no permanent limitations
on the op-
eration of the ROTEX RoCon.
Messages that are displayed
with an error code E.... and red
back-lighting
required error correction by an
authorised and
trained expert heating technician
.
For information on warning messages, see chap. 7.4.
●
Detecting and remedying the cause of the malfunction.
– Contactor triggered:
Nothing shown on the display in the controller. Ascertain
cause of triggering the contactor and remedy fault. Start the
system again.
Once the cause has been remedied, the system will
resume operations as normal.
– Contactor not triggered:
a) No error codes are shown, but the system is not working
properly. Search for and rectify faults (see chap. 7.4).
Once the cause has been eliminated, the system contin-
ues to work normally.
b) Error codes are displayed as long as fault conditions are
present. Search for and rectify faults (see chap. 7.4). If the
fault message is still displayed after the cause of the fault
has been corrected, the system must be disconnected
fromthe power supply for at least 10 in order to unlock it.
Once the cause has been eliminated, the system contin-
ues to work normally.
CAUTION!
Electrostatic charges can lead to voltage arcing
that can destroy the electronic components.
●
Secure potential equalisation before touching
electronic parts (e.g. by touching an earthed
metallic part).
