USA: +1 330 486 0001 Singapore: +65 6779 9091 Double sheet sensor 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 +UB or -UB, to avoid possible interference or improper functionality. 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 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 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. 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.

USA: +1 330 486 0001 Singapore: +65 6779 9091 Double sheet sensor Programs *) The measurements were made under the following conditions: d = 45 mm, a = 10 mm,  = 0° *) The measurements were made under the following conditions: d = 45 mm, a = 10 mm,  = 35° 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 -UB (for > 500 ms), the mode changes. When the "Program selection“ mode is active, switching on function input (PK) on to +UB (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! Modes 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 yello w LED flashes at low frequency
• the flashing frequency increases in line with the signal strength
• the yellow LED lights up continuously wh en 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 B (for > 500 ms) causes the next program to be selected in cyclic sequence (program 1 follows 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.

USA: +1 330 486 0001 Singapore: +65 6779 9091 Double sheet sensor 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 PACTware DTM The double sheet sensor can be connected using a V15S-G-0.3M-PUR-WAGO terminal adapter. Connect the sensor to the terminal adapter according to the table below. 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.
