SENSOREN
The choice of cable, the installation, protection and electrical connection must be conform to the corresponding special
regulations or country regulations. The electrical connection must only be carried out by qualified personnel.
�The
device shall be protected from electrostatic discharge at the time of installation and operation.
�The
device is not suitable for the installation in explosion-hazard areas.
�The
device must be installed with a designated process adapter sleeve.
�The
connected load circuit must be fused to the maximum output current in order to prevent a defect in the output in
case of a short circuit. Do not connect any additional loads to the terminals for the voltage supply of the device.
�The
two poles of the device shall be disconnected from the mains if live parts can be touched during operation.
�The
supply is not electrically isolated from the sensor ground
�An
incorrect installation and wrongly set parameters can interfere with the operation of the application or even cause
damage. Therefore, independent safety devices should always be available and adjustments must only be carried out by
qualified personnel.
�Do
not direct the spray jet to the electric outlet during external cleaning with a high-pressure cleaner.
The DIN 61000-4-part-5:surge is not accomplished completely due to the product design. Therefore, an additional
protective recommended (e.g. a varistor) or the supply by a protected 24V/DC switched-mode power supply for connecting
Operation
Depending on the sensor type, the electrical connection has to be carried out directly
through the terminal block on the electronics or through the built-in M12 plug. The 24
VDC supply voltage is connected according to the wiring diagram. The active PNP
output must be connected exemplary to a processing control system.
Note: The output voltage is proportional to the input voltage!
Example: At a supply voltage of 20 VDC the output signal has a voltage of < 20 VDC.
Please note that the output can only switch the positive side of the supply voltage
(max. 50 mA). Switching load against ground is not possible!
Settings
The switching action of the sensor can be defined via the configuration switch. It is
possible to adjust the logic, a delay time and the switching threshold. Additionally, the
sensor can be connected to a software whereby the measured values can be
monitored online. Thus, the switching thresholds can be adjusted individually
according to the respective process requirements.
Switch 1
Setting 0: full detector, the output switches by the time the sensor tip is covered by a
medium.
Setting 1: empty detector, the output switches by the time the sensor tip is not
covered by a medium (reverse performance).
Switch 2-3
As stated in the chart “delays”, a switch-on delay and switch-off delay of the output
signal can be set (both times are equivalent respectively). The delay can be used
perfectly whenn the medium does not cover the sensor tip permanently (debouncing).
Example 4 sec: The output reacts only 4 seconds after the cover of the sensor tip is
changed. Thereby, turbulent liquid water surfaces can be repressed.
Switch 4-6
The sensor can be set according to the respective medium via the switch-on and
switch-off thresholds. The percentage measured value is non-dimensional. The switch
setting “4, 5 and 6 = on” enables the parameterization of an user-specific switching
threshold via the software of the PC. A hysteresis can be defined through the switchon
and switch-off thresholds whereby secure switching operations can be achieved,
e.g. in frothing media.
Note: The measured value differs depending on the temperature or production
method of the medium. Thus, the switching thresholds should be provided with
tolerances.
