Double plate sensor UDCM-30GM-085-3E3
Description of sensor functions
The ultrasonic double-sheet monitor is deployed in all situations in which the automatic distinction between single and double 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,
- single sheets
- double sheets or multiple sheets
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 evaluation electronics are integrated into
an evaluation unit together with a sensor head in a compact M30 metal housing.
Electrical connection
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
ality.

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 mode!
White: WH Single sheet output
Black: BK Double sheet output
Gray: GY Air 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 function input (PK) is switched to voltage-free during operation due to an error (broken cable, coming loose because of vibration),
the 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 materials. 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.

The specified intended uses of program 1 ... 4 show orientation values for the user. In specific individual cases, the appropriate program
to be selected for the respective material used must be empirically determined. The starting point here should be standard program 1.
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
ing on function input (PK) to +U
(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!
(for > 500 ms), the mode changes. When the "Program selection“ mode is active, switch-

Amplitude control
During installation, the amplitude control can be used to check whether the ultrasonic amplitude at the receiver is sufficient. If the transmitter 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 follows
B
through to program 4).
Notes:
A complete device consists of an ultrasonic emitter and an evaluation unit with an ultrasonic receiver. 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.
During installation, ensure that the ultrasonic signal cannot bypass the material being detected through multiple reflections. This can
happen if, for example, large surfaces for sound reflection exist transverse to the direction of sound transmission. This can be caused
by the use of unsuitable holding devices or large-surface system components. In the case of reflective system components, they must
be covered with sound-absorbing material or a different installation site must be chosen.
To ensure problem-free detection of double sheets, an air gap is required between the sheets. This prerequisite might not be met in
cases where two sheets adhere to each other by means of an oil film, thus resulting in the detection of a single sheet only.
If two or more UDCM 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.
Parameterization using PA C Twa r e 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.
