MANUALE D’USO – USER MANUAL
- [S9=8] PROPORTIONAL functioning REFERRED TO VALUE SENT ON RS485
(0-100%):
This type of functioning envisions steam output in proportion to value set in register 1537 by
means of Modbus-RTU communication.
In this functioning mode the discharge forcing and steam output controls envision a 1 minute
time-out; if during this period the control is not send back on Modbus, upon expiring of this
time the steam output will be set at zero and
the discharge pump will be disabled. This
places the humidifier in safe conditions in
case of accidental disconnections of the
communication network.
Set the second level variable S9=8 and
connect the instrument to the RS485 line with
clamp 32 to line A (TX+) and clamp 31 to
line B (TX-).
For further information on Modbus-RTU
Protocol of the humidifier, refer to document
“MODBUS-RTU_UMIDMS03”.
HUM2 BOARD DIGITAL INPUTS
Four digital inputs with the following meaning are present on the humidifier electronics:
Digital inputs In1, In2 in low voltage.
Input In1 (clamps 24 and 25): input with configurable meaning depending on second level
variable In1. By default, this input is configured as “main enabling”, active with close contact
between clamps 24 and 25.
Input In2 (clamps 24 and 26): input with configurable meaning depending on second level
variable In2. Input active with closed contact between clamps 24 and 26 or by means of jumper on
board present at side of clamp 26. By default, this input is configured as "discharge pump
activation" to enable discharging the cylinder in the absence of the console. Digital inputs In3, In4
in high alternate voltage (mains voltage).
These inputs feel mains voltage and for them to
function require connection of one of the two
phases (in our case, neutral) to clamp 4.
Input In3 (clamps 4<neutral> and 6<phase> ):
input with configurable meaning depending on
second level variable In3. Input active with input
phase to clamp 6.
Input In4 (clamps 4<neutral> and 5<phase> ):
input of maximum water level in active cylinder
with input phase to clamp 5.
In ES series humidifiers input In4 is pre-wired.
If none of the inputs In1, In2 and In3 is
configured as enabling, the humidifier, for
working, does not need an external enabling.
