Mounting and operating instructions Signs and Symbols Warning This symbol signals passages in the manual which must be observed at all times. Non-compliance can cause injuries or material damage. Warning Laser This symbol appears in front of warning passages concerning the danger of laser beams. Information This symbol signals passages with useful information. -
Page 7: Appropriate Use
Mounting and operating instructions Appropriate use The VDM18 sensor is not authorised for use in protecting human safety on machines and during technical applications. The VDM18 is an optical sensor and measures distances without contact. When combined with another VDM18 sensor, the thickness of objects can also be measured. -

Page 9: Electrical Installation
Mounting and operating instructions Electrical installation Warning: Pin 1 and pin 5 must not be connected to operational voltage as this will destroy the VDM18 sensor. Turn the sensor connector plug according to the installation position (Illustr. 1) so that the connection cable can be freely connected without being bent. -
Page 10: Instructions Of Use
Mounting and operating instructions Instructions of use Control panel The VDM18 has various modes and is confi gured using the S and T buttons. Button Set button: Change / confi rm a setting or set a switching point Toggle button: Select a function (proceed to the next function) The selected settings and signal condition are indicated by LEDs. - Page 11 Mounting and operating instructions If no change occurs: Press T button for longer The fi rst function follows the last available function. If the wrong function is selected by mistake, it is not possible to jump directly back to the pre- vious function number.

Page 15: Averaging
Mounting and operating instructions Averaging The measuring result (output signal) is smoothed by averaging. The measured values are read continuously into a memory and the arithmetical mean is formed. Functions 14 and 15 (page 33) determine the number of measure- ments (10 or 100) to be used for averaging. -
Page 16: Automatic Centre Mode
Mounting and operating instructions Automatic centre mode The output characteristic curve 4 – 20 mA is displaced with this function. When the automatic centre function is activated and Q = +U , the current measured value is equated with the output value of 50% = 12 mA. The incline of the characteristic curve is maintained and the minimum and maximum values of the characteristic curve are limited by the measuring range. -
Page 17: Difference Hold Mode
Mounting and operating instructions Difference hold mode When the difference hold function is activated and Q = +U , this function detects the difference between the mini- mum and maximum value of the measuring signal and stores it. If Q = -U , the last differential value is transmitted at the analogue output. -
Page 18: Differential Measurement Mode
Mounting and operating instructions Differential measurement mode Differential measurement can only be used with /88 option of VDM18. Simultaneous connection to SPC control or a PC via the RS 485 interface is not possible with differential measurement. With this measuring procedure, two VDM18.../88 sensors are connected to one another. The measuring ranges can overlap (1), be directly adjacent (2) or apart (3) (Illustr. - Page 19 Mounting and operating instructions 4. Insert reference object of known width in measuring range. Warning: LED “OK” (Good target) must light up on both sensors. 5. Confi gure the second VDM18.../88 sensor as the master. Activate function no. 25 (page 34). Warning: The sensor can only be confi...
