“Password active“
Switches the password request on/off. If the password request is set “on“, the system / program
parameters can only be changed after the password has been entered.
“Password”
Without password the system data are unprotected against unwanted change. Therefore a
password should be set as soon as the installation is completed and regular operation has
commenced. The factory preset password is “0000”, it can be set to a value between 0000 and
9999.
“Pairs of sensors“
Defines the number of connected sensors. Those sensors are then available for measuring. To a 2-
channel system I20-2 max. 2 sensors can be connected, at a 4-channel system I20-4 max. 4
sensors can be connected.
“Sensor type“
Currently the sensors IS/IE20-30S or IS/IE42-30S and ISQ/IEQ42FS or ISQ / IEQ160S are
available. For those sensors characteristic curves for linearization purposes exists.
“Default settling time”
Defines the default time which the system requires to achieve stable measurement results, if the
program parameter “settling time” is not available. For details refer to chapter 3.7.2.
“Measurement mode“
Sets how the measuring is to be triggered. The following modes are available:
• Ext. Single (default setting)
Here a single measuring is performed. For doing so, the signal “Measuring start“ must be
externally applied. Another measuring requires a new flank of the “Measuring start“ signal.
• Demo
The demo mode is only intended for test and demonstration purposes. In this mode
measuring is performed until the demo mode is switched off again. For doing so, another
mode must be selected. The repetition time of the measuring is 4 ms.
• Ext. Permanently
Here the measuring is maintained as long as the signal “Measuring start“ is applied.
The repetition time of the measuring is 4 ms.
• Ext. Special
As Ext. Permanently, but: the highest value measured during a measurement cycle is
displayed and maintained until a new measurement cycle is started. This also applies for
the 0-1-2-Warning outputs.
“Hold if 2-sheet“
Selection: “yes” or “no“.
• Yes:
The outputs (0-sheet, 1-sheet and 2-sheet) are activated according to the number of
sheets between the sensors. If the equipment detects 2-sheet, the output 2-sheet is
activated and the equipment is blocked until the 2-sheet condition is cleared, see
Section “Mode of operation 2-sheet hold“.
• No:
The outputs (0-sheet, 1-sheet and 2-sheet) are activated according to the number of
sheets between the sensors. The equipment does not block the operation if double
sheet is encountered.
