MANUALE D’USO – USER MANUAL
Failed discharge control auto-test (Pre-alarm)
This alarm does not block steam output; the
cause of the problem must be eliminated prior to
successive test performed every 10 hours of
functioning of the electrodes to avoid occurring
of the blocking error E6.
Alarm is automatically reset upon successive
discharge test if it passes or upon humidifier
switch-off.
Check the discharge or bottom of the cylinder
are not obstructed and the pump is not faulty or
disconnected.
In case pump test I1 is not considered
necessary, it can be disabled by bringing
variable S10=0
Discharge control auto-test failed for second
consecutive time.
This alarm blocks steam output to avoid
damaging the unit and cannot be silenced.
To reset the alarm switch-off humidifier.
Check the discharge or bottom of the cylinder
are not obstructed and the pump is not faulty or
disconnected.
In case pump test I1 is not considered
necessary, it can be disabled by bringing
variable S10=0
In a Master/Slave humidifiers configuration,
the Master unit cannot find a slave connected
to it.
Such alarm does not block normal functioning
and, upon connection restore, the alarm is
automatically reset.
Check connections between master unit and
slave unit.
Check second level MS and Ad parameters
relating to Master/Slave configuration.
In a Master/Slave humidifiers configuration, the
unit has lost communication.
Such alarm blocks the unit but, upon connection
restore, the alarm is automatically reset.
Check connections between master unit and
slave unit.
Check second level MS and Ad parameters
relating to Master/Slave configuration.
Alarm from digital input (usually safety
thermostat) .
This alarm starts if one of digital inputs
configured as alarm persists for more than 5
seconds.
It blocks the steam production and activates the
acoustic signalling (can be switched off).
The alarm is automatically reset when the alarm
input disappears.
(usually safety thermostat)
SERIOUS alarm from digital input (usually
safety thermostat) .
If the E8 alarm persists continuously for a time
longer than t5, starts the E9 serious alarm.
The E9 alarm starts also if in the space of 12
hours occur 3 alarm E8 situations.
It blocks the steam production to avoid the
damage of the unit and it cannot be switched off.
The E9 alarm is disabled with t5=0.
To reset the alarm, the humidifier has to be
switched off.
(usually safety thermostat)
Differential protection upstream of the power
supply line of the humidifier intervenes.
Water present in lower part of humidifier due to
a fault or after maintenance causing unit
dispersion towards the ground.
Bring unit in safe conditions following
instructions in chapter 7.2.
Carefully dry all wet parts and activate the unit
again.
Humidifier produces insufficient steam.
One of the phases may be interrupted. Check
current absorption on all phases.
Check the steam tube is not obstructed by
water stored in a lock of the tube. The tube
must not create siphons (see chapter 8)
