W22, E22 Maximum filling time and W23, E23 No electrode current
Function:
monitoring of the filling cycle
Procedure:
if the filling cycle ist not finished within 20 minutes (maximum
filling level or reference current not reached) a warning is triggered. If the
current is below 1.5 % warning W23 is triggered otherwise warning W22.
The
procedure
is as follows:
• 20 minutes filling -> W22 or W23 active
• 20 minutes filling
• 60 minutes waiting
• 20 minutes filling
• 20 minutes filling
• 60 minutes waiting
• 20 minutes filling -> E22 or E23 active
At the end of a filling cycle of 20 minutes the warning message can change
from W22 to W23 or vice versa.
If a module with activated warning W22 or W23 goes on standby the warn-
ing message remains existing (advantage: you can see at any time that a
module has problems with the water supply).
In addition to the normal monitoring of the maximum filling time the filling
cycle is interrupted after 300 seconds for 5 seconds (except with the oper-
ating mode Ship).
When the steam production is restarted (main contactor activated) the filling
valve is blocked for 60 seconds (awaiting current rise due to the heating
up of the water).
