Digital_input_function 98 Determines which function will be executed if the

Digital input [97]
on the mainboard or one of the relay
boards is loaded externally with level "1" (= 12 V).
Nominal power output 99 The steam output range given on the name plate derived from the allowable range of suply voltages
Term [Index] Explanation
Output signal 69 Signal 0... 10 V on terminals 12 and 13 (GND), which is proportional to the input signal. Can be used to
control downstream units.
Input signal 72 The electrical signal fed to the control at the ST08 plug of the mainboard or the ST05 plug of the relay board.
Depending on the signal characteristic (Voltage, current or resistivity progress), a certain pin of the
corresponding plug is used. The signal range of the input signal (e.g. 0...10V) is to be adapted by setting of
the related parameter. Using the Correction_x_signal [49] parameters, the output signal of a humidity
sensor may be calibrated.
External controller 73 The control uses the output signal of an external controller to control the power element for steam
generation. The input level of the control can be adapted to different signal types and value ranges. Other
possible input signals are the output signal of a humidity sensor (in connection with the internal PI controller),
the switching contact of a

Hygrostat [6]
(for 
1 step operation [44]
) and a 
Software command [12]
via
the 
Communication interface [13]
.
Dropout delay 74 By assigning the "8" value to one of the relay contacts, a control signal for the delayed closing of a steam
valve is made available for pressure reduction. The dropout delay is set with the "Humidification_off_delay"
paramter. Factory default is 60 s.
Main contactor 75 The installed main contactors are labelled K1...K4. The operating cycles of the main contactor(s) are
monitored and compared with the value specified by the manufacturer for the expected service life. When
the stored value is reached, the message "Service_main_contactor" is generated. After the main contactor
has been replaced, the status message must be deleted, for example using the

Main_contactor_K1_Reset = "1" parameter.

Virtual interlock (safety) system 86 If control via 
Communication interface [13]
was selected, software is used to place a logical switch in
series with the hardware interlock (safety) system. This switch can be opened and closed via

Software
commands [12]
. If the hardware interlock (safety) system is closed and the switch is opened via software
control command, steam production is stopped and the unit is placed in "Remote switch-off" status.
Supply voltage 89 The units are designed for connection to supply voltage ranges (e.g. 380 to 415 VAC in case of a 400 VAC
unit, s. name plate)
Unit name 90 Here, "Plant 1" is entered by default.
Weekly timer 91 The timer makes it possible to program 2 periods per day of the week, each defined by a start time and a
end time. The humidity set-value can be preset for each time period.
Recording 93 The control can record 10 data sets internally on a rolling basis. Snapshots of the unit status are carried out
at intervals of 10 s, which can be helpful for troubleshooting. When the storage space is filled, a new set of
data overrides the oldest entry. The complete record can be saved to a USB stick with NTFS formatting.
Slave 94 The unit functions as a slave in a master/slave arrangement, where a control unit (master) can control up to
3 slaves for the purpose of improving the output performance of the entire system. The slaves are switched
sequentially. The output signal of the master on terminals 12, 13 is connected to the input terminals of the 1.
slave. The input signal assignment of the 1st slave (and all subsequent ones) must be set to "Slave", this
also applies to the output signal assignment for the master and all slaves.
Warning message 95 The electrodes (for the

ELDB [77])
, the blow-down pump and the solenoid valves are items with limited
service life due to wear and tear. They must be checked during maintenance works and replaced if required.
To avoid unplanned maintenance requirements, alerts can be set up for the respective items, which are
activated when a defined state of wear is reached. The criteria for the alerts to be triggered can be defined in
three stages each through the sensitivity setting.
PI controller 96 Internal controller with control characteristics which contain a P roportional part and an I ntergal part. Both
parts can be changed as parameters.
Digital input 97 Digital input on the mainboard and on the relay boards for switching functions. A logical meaning (e.g. timer
start) is assigned to the digital input via the

Digital_input_function [98]
parameter. The digital input must be
wired on-site in accordance with its use, e.g. with a

Pushbutton [106]
or a

Switch (NO) [102]
against
the 20 VDC on terminal 8 on the mainboard terminal strip ST08 or the terminal strip ST05 on the other
available boards. When the
20 VDC voltage is applied (short-term via a

Pushbutton [106]
or permanent
via a 
Switch (NO) [102
] ), as required in accordance with 
Digital_input_function [98]
parameter setting),
the switching function is carried out.
