USER MANUAL
FIRST IGNITION
1.
Verify that the default setting is compatible with the signal connection made; if different, configure the
electronics correctly before powering up as described in chapter 2.
2.
Before connecting the humidifier, check the correct connection of the phases and of the type of input
signals; check also the correct connection of the mains water, the water drain and the steam tube.
If the mains water connection line has been made with pipes that may contain oily residues or
other substances that generate foam, it is essential to wash it by letting the water run for a few
minutes.
3.
Check that there are no water leaks inside the humidifier.
4.
Give power supply to the humidifier.
5.
The humidifier will run a water drain for a few seconds, emitting a long beep.
6.
The humidifier is now in STAND-BY mode. To switch it on, press the ON/OFF – STAND-BY key: the
humidifier will display the humidity value measured by the probe, if configured in
4-20mA PROPORTIONAL mode, or it will display the current consumption, if configured in ON/OFF
and 0-10V PROPORTIONAL mode.
7.
The humidifier to work requires the digital input 1 to be enabled by means of a voltage free contact
(terminals 24 and 25 on the electronic board MasterHUM2) regardless of the selected operating mode
and if the parameter In1 = ± 2. When not enabled, the display alternates the word OFF to the normal
display.
STEAM PRODUCTION
1.
Set the required humidity value by pressing the SET key and increasing the value with the UP key, in the
4-20mA PROPORTIONAL models (if the set value is higher than that measured by the probe, steam
production begins); or give ON/OFF or 0-10V consent in the ON/OFF or PROPORTIONAL 0-10V
models.
2.
Allow the cylinder to fill up until the water starts boiling, then completely empty the cylinder with the
MANUAL DRAIN key to start the pump. Repeat the operation 1-2 times.
3.
Now the humidifier is operational and can function properly in a completely autonomous way.
SMART PRODUCTION FOR LOW CONDUCTIVITY
Smart production function with low conductivity water.
Set parameter S11=1 if all the following conditions are true:
-
the requested percentage of steam production Pr was not reached;
-
at start-up, the cylinder fills up completely and triggers the level sensor;
-
the current measured with a cylinder full of water is greater than 0.5A, but it is not sufficient to
guarantee the required steam production.
With the "Smart production for low conductivity" function activated, the humidifier automatically regulates
the percentage of steam production based on the conductivity of the water. If the water is not sufficiently
conductive at the first start, the percentage of steam production is reduced to avoid reaching the level sensor
and the consequent blocking of the machine.
The humidifier will not work immediately according to the
steam production percentage set with parameter Pr, but the purpose of the procedure is to reach it
gradually
. When the function is active, the value of the calculated steam request can be displayed in the PrL
parameter (first level of programming).
The Smart production for low conductivity function only modifies the percentage of steam production. In the
case of water with extremely low conductivity, it is advisable to modify the following parameters:
S2
Deconcentration discharging interval: set
30 ÷ 50 min
S4
Discharge of water for inactivity: set
0
S8
Set
= 0
to activate step water loading
