MANUALE D’USO – USER MANUAL
In case of anomalies, the EASYSTEAM humidifier warns the operator by means of alarm codes,
visual and acoustic signalling.
Upon verifying of an alarm condition, the display icon switches on, the alarm relay is activated (if
configured), the internal buzzer is activated and one of the following alarm codes is displayed.
The internal buzzer can be inhibited at any moment by pressing the "Silence" key. Pressing the SET
key once restores sound signalling.
There are three types of alarms, depending on their seriousness:
- Automatic reset (the alarm is automatically reset upon disappearing of the problem)
- Manual reset from keyboard (alarm is automatically reset)
- Manual reset by disconnecting the board (serious alarm cannot be silenced)
Without console, it is possible to identify the type of alarm present by counting the flashes of the
red LED on board the Master (e.g. E3 there are 3 flashes followed by a long pause. Whereas, alarm
E0 is signalled by the permanent switch-on of the red LED on Master).
To reset an alarm without automatic reset in display absence, disconnect the electronics. By default,
output Do4 (clamps 7 and 8) is set as alarm relay (second level variable dO4 = 1).

Maximum water level inside cylinder
The water inside the cylinder has reached the
maximum level sensor and absorbed current is
within admitted range (> 0.5A).
(sound signalling is not had during this alarm)
If the water inside the cylinder reaches maximum
level sensor at the beginning of a steam output
cycle, the cylinder completely discharges to
attempt eliminating the foam present (anti-foam
cycle) and steam output starts again. If the level
is still reached after the anti-foam cycle, the
water charge blocks and steam output continues.
Suspended particles produced by oils or
greases present in the charge line can cause the
forming of foam that activates the level.
Completely wash the cylinder a few times by
means of manual discharge immediately after
complete charge.
Water conductivity above 1300S/cm can
cause the forming of foam. Increase frequency
of deconcentration discharges by acting on
parameter S2.
Verify there is no water underneath the cable-
carrier circular tube, on the upper part of the
cylinder. If present, this can penetrate the
circular tube and create a false contact on level.
Carefully dry everything.

Stay of maximum water level inside cylinder
The maximum water level inside cylinder sensor
has been continuously activated for more than
one hour after an anti-foam cycle.
This alarm blocks steam output until its
acquisition (pressing of Silence key).
Use the same arrangement as for the
"Maximum water level inside cylinder".
No connection between NANO EasySTEAM
display and MasterHUM2 electronics
Check connection on J1 connector and of
connection cable.
Functioning anomaly of the ambient probe set
in variable S9.
Check correct configuration of used probe
(variable S9 and electric connections on
specific clamps). If problem persists, replace
the probe.
