7.3 Tank monitor: Handling multiple faults
For every alarm - whether informative (green) or critical (red)
– an error code blinks
in the display.
If several faults occur simultaneously, the code for the most recently occurring fault
blinks in the display.
If both informative and critical faults occur, priority is always given to the critical error
code (in the example this would be fault F10)
Exception in cooling mode: sensor faults flash alternately with critical or informative
alarms.
Cancelling faults:
(both LEDs flash alternately)
The most recently occurring fault (example F10) blinks in the display.
Press RESET button -> The horn switches off, the most recently occurring fault
(example F10) continues to blink in the display.
Identify the fault using the list of faults -> Press RESET button ->
the red LED continues to flash in order to indicate that there are further critical
faults.
The next fault (in the example F11) blinks in the display:
Identify the fault using the list of faults -> Press RESET button -> etc.
When the last critical fault (example F02) has been reset
: (red LED permanently
lit)
Der The first informative fault (example F34) blinks in the display:
Identify the fault using the list of faults -> Press RESET button ->
The green LED continues to flash in order to indicate that there are further informa-
tive faults.
The next informative fault (example F20) flashes in the display...
When the last informative fault has been reset, the green LED goes out, while
the red LED stays on permanently.
It is only when the cleaning cycle is active for at least 10 minutes that the tank monitor
resets all critical alarms.
7.4 Tank monitor: Display fault memory
If the tank monitor's red LED is permanently lit, it means that critical faults have al-
ready been acknowledged, but still exist. These error codes are registered in the
device's internal fault memory and can be consulted as follows:
Show the last 5 critical faults from the fault memory
SET button in OFF mode: the code for the first critical fault is displayed (in the
above example F02).
SET button again: the next error code is displayed (in the example F05).
If no button is pressed for 3 seconds, the display switches back to the time.
It is only when the cleaning cycle is active for at least 10 minutes that the tank monitor
resets all critical alarms.
Cancelled critical faults are
transferred to the device's in-
ternal fault memory and can
be consulted at any time.
