6.3 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)
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
informative 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.
6.4 Display fault memory
If the red LED of the tank monitor flashes permanently it means that critical errors
have already been confirmed, but still exist. These error codes are registered in the
internal error memory of the unit. They can be read out as follows:
Display of the last 5 critical errors from the fault memory
Press SET-button: The display indicates the code of the first critical error
(in the example above F02).
Press SET-button again: the next error code (in example F05) is indicated..
If no button is pressed for 3 seconds the display switches back to temperature and
time.
Only when the cleaning cycle has been active for at least 10 minutes, the tank
monitor resets automatically all critical alarms.
Cancelled critical faults are
transferred to the device's in-
ternal fault memory and can be
consulted at any time.
