Double sheet sensor UDC-18GMA-400-3E3
Description of sensor functions
The ultrasonic double sheet monitor is used for double sheet detection in all situations in which the automatic distinction between double and single sheets is required in order to protect machines or avoid waste production. The double-sheet monitor is based on the ultrasonic through-beam principle. The following can be detected:
- No sheet, i.e. air,
- Individual sheet
- Double sheet
A microprocessor system evaluates the signals. The appropriate switch outputs are set as a result of the evaluation. Changes in ambient conditions such as temperature and humidity are compensated for automatically. The interface electronics is integrated into a
compact M18 metal housing together with a sensor head.
Switching on
The sensor is equipped with 6 connections. The functionality of the connections is described in the following table. The function input
(PK) is used to assign parameters to the sensor. (See Output pulse extension, Alignment aid and Program selection). During normal
operation, the function input must always be securely connected with +U
lity.

Normal mode
The sensor is working in normal mode if the function input (PK) is applied to -UB or +UB when the power source (Power-On) is supplied,
as shown in the output pulse extension table (see below).
Displays:
LED yellow: Detection of air
LED green: Detection of single sheets
LED red: Detection of double sheets
Switch outputs:
The switch outputs are only active in normal operation!
White: WH Single sheet output
Black: BK Double sheet output

Output pulse extension
Switching the function input (PK) on to -UB or +UB makes it possible to select a minimum pulse width of 120 ms for all output pulses of
the three switch outputs.

Please note:
This can result in a condition in which more than one switch output is switched through!
Display Mode
The selected parameter assignment of the sensor can be displayed by switching the function input (PK) to voltage-free during normal
operation. The green LED displays the program number (the number of flashing pulses (1 ... 4) = the program number).
The outputs are inactive during this time.
If the function input (PK) is switched to voltage-free when power is supplied (Power-On), the sensor will also work in display mode.
If the unit is switched to voltage-free while the function input (PK) is in operation due to an error (broken cable, coming loose because
of vibration), display mode acts as a fault display.
No output pulse extension for switch outputs
Output pulse extension of all switch outputs to at least 120 ms
Parameter assignment
The sensor is equipped with 4 programs for different ranges of application. This makes it possible to work with a wide range of material.
The user can select the program best suited for a specific application.
The default setting, Program 1, is designed so that no change in the setting is required for most applications.

Procedure for assigning parameters
It is possible to switch to additional parameter assignment modes from the display mode:
Alignment mode -->
Program selection mode -->
Alignment aid mode --> (for checking)
When the function input (PK) is applied to -U
ching on function input (PK) on to +U
B
(for > 500 ms), the mode changes. When the "Program selection“ mode is active, swit-
B
(for > 500 ms) selects the next program level.
Disconnecting the power supply causes the system to exit the current mode with the selected program change.
The switch outputs are not active while parameters are being assigned to the sensor!

Amplitude control
During installation, the amplitude control can be used to check whether the ultrasonic amplitude at the receiver is sufficient. If the trans-
mitter is not aligned properly in relation to the receiver, maximum sound energy is not transmitted to the receiver, which may result in
the incorrect detection of materials.
When the sensor detects an area of air (yellow LED lights up), the UDC begins to display the strength of the measured amplitude signal:
- if the signal is weak, the yellow LED flashes at low frequency
- the flashing frequency increases in line with the signal strength
- the yellow LED lights up continuously when the signal strength is sufficient.
The single sheet function (green LED) and double sheet function (red LED) are now active. This can be used to check the correct
function of the sensor.
Program selection
In the program selection mode, the current program is displayed by the green LED (number of flashing pulses = program number).
Applying the adjustment input (PK) to +U
(for > 500 ms) causes the next program to be selected in cyclic sequence (program 1 fol-
B
lows through to program 4).
Notes:
A complete device consists of an ultrasonic emitter and an evaluation unit with an ultrasonic emitter. The sensor heads are optimally
adjusted to each other when they leave the factory. Therefore, they must not be used separately or exchanged with other devices of
the same type. The plug connector on the emitter/receiver connection cable is only intended to be used for easier mounting, not to
replace units.
Very light papers (for example handkerchiefs) or perforated papers are not always suitable for double sheet detection because of their
physical characteristics.
If two or more double sheet controls are used in the immediate vicinity of each other, there may be mutual interference between them,
which can result in improper functionality of the devices. Mutual interference can be prevented by introducing suitable countermeasures
when planning systems.
When installing, care has to be taken that the ultrasonic signal cannot pass around the material that is to be detected, due to
multiple reflections. This can happen if large surfaces are present at right angles to the direction of sound propagation. This can
be the case if unsuitable mounting brackets are used, or if assemblies with large surface are part of the machine. In the latter
case such machine parts should be covered by sound absorbing material or a different location for the installation should be
chosen.
Parameterization using PACTwa re DTM
The double sheet sensor can be connected using a V15S-G-0.3M-PUR-WAGO terminal adapter.

The sensor features a time lock. If no communication request occurs, the time lock blocks parameterization of the sensor 30 seconds
after the supply voltage is connected. Start PACTware before switching on the sensor so that the communication request can be made
in time.
