Periodical drain
When using water rich in substances such as humus and lime, a periodical
drain cycle should be set for the cylinder to avoid accumulating
residues.
To enable the periodical drain, set parameter b1 to 64. In this way, every
24 h the humidifi er will drain all the stagnant water in the cylinder, and
the display will show code "dP" (periodical drain). If the periodical drain is
enabled, the number of hours between two periodical drain cycles can
be set using parameter "bE".
Note:
For the manual drain function, see chap. 6, for the mechanical drain see
paragraph 9.4.
12.5 Automatic insuffi cient supply water
management
The humidifi er checks whether there is no supply water or the fl ow-rate
of supply water is too low, by controlling if the current at the electrodes
increases after opening the fi ll solenoid valve.
In this case, the humidifi er:
•
displays alarm "EF"
•
activates the alarm relay,
•
opens the contactor and closes the fi ll solenoid valve for 10 minutes.
After the 10 minutes, the fi ll solenoid valve is opened, the contactor closed
and the phase current measured: if it increases the alarm is deactivated,
otherwise the procedure is repeated.
NOTE: the alarm is reset automatically and is managed according to the
procedure described above.

12.6 Alarm relay switching

Once the operating hours corresponding to the cylinder maintenance
request have been reached ("CY" alarms), the alarm relay (if there are
no other alarms active) will switch for 10 seconds every 12 hours, until
reaching the "Mn" alarm.
This function is activated using parameter b1 (see paragraph 11.6);
