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 .
T o enable the periodical drain , set parameter b1 to 64 . In this way , every
24 h the humidi fi 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 insufficient supply water
management
T he humidi fi 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 humidi fi er:
•
displays alarm “EF”
•
activates the alarm relay ,
•
opens the contactor and closes the fi ll solenoid valve for 10 minutes .
A fter 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 .
NO T E: 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 .
T his function is activated using parameter b1 (see paragraph 11 . 6);
normally disabled
12.7 Auxiliary contact management (active
fan request)
T he auxiliary contact can be used to:
- remote signalling of steam production request (but not the actual
value);
- activation/deactivation of an external fan unit , based on whether the
steam production request is present .
A ctivating this function by parameter b1 , the contact is activated
(CLOSED) during steam production , with a delay of A 6 seconds , and
deactivated (OPEN) with a delay of A 7 seconds .
During A 6 and A 7 the symbol (fan) will fl ash on the display , during
activation the symbol (fan) will be on steady .
During the manual drain (see Chap . 6 . 12) the contact will be deactivated
(always after the delay A 7)
During pre - wash (see Chap . 6 . 1) the contact be activated , with the
corresponding delays .
12.8 Manual procedure
T his procedure is used to manually control the devices on the
humidi fi er .
From the main screen , press the PRG button for 2 seconds .
Enter the password 70 using UP or DOWN .
T he display will show MAn
Press PRG .
T he display will show tlr
T hen scroll the various devices using UP and DOWN:
- tlr = Contactor
- drn = Drain pump
- FiL = Fill SV
- drt = Drain tempering SV ( not used )
- ALr = A larm relay
- FAn = A uxiliary contact (fan)
Pressing PRG from any these options shows:
ON if the device is currently active
OFF if the device is currently inactive
Press PRG; the display starts fl ashing
Press UP or DOWN to modify the value
Press PRG to con fi rm .
Press ESC to return to the previous display .
