1. How do safety light grids function for monitoring hazardous areas?
Answer:
Safety light grids are multi-beam photoelectric safety devices that are designed to immediately stop dangerous movement of a machine. Transmitter and receiver are set up in the access area of the danger area to stop the plant when the light beam is interrupted. This is implemented by a suitable safety relay and its relay contacts.

2. How do capacitive sensors detect levels through a tank wall?
Answer:
The level sensors of types KQ/KG/KI/ can detect levels through plastic walls. The sensor with the new ifm handling concept is adjusted so that the plastic wall is suppressed and the sensor reacts only to the medium behind it. In addition, residues of liquid can be suppressed with ‘full adjustment’.

3. What level sensors are suited for the detection of viscous or adhesive media?
Answer:
The LMT level sensor is perfectly suited for the detection of viscous media, powders and media containing solids such as ketchup or vegetable oils. Its sanitary design ensures that it is ideal for the food industry and it has approvals to EHEDG /3A. The unit operates to the impedance spectroscopy method. It examines the electrical behaviour of the media to be monitored in the frequency range between 50 and 200 MHz. The various media show characteristic behaviour. The presetting of the unit allows detection of the presence of certain media; deposits or foam, however, are suppressed.

4. What sensors enable complete and smooth product transport via a robot arm by means of vacuum?
Answer:
The PQ pressure sensor qualifies for this task thanks to its small compact design. The unit measures the precise pressure and underpressure in pneumatic applications with its silicon measuring cell. The measuring cell is insensitive to liquids such as condensation water and deposits.

5. What display options does the PG2xxx electronic manometer provide?
Answer:
The clearly visible scale features an LED ring, which has one LED per tick mark. This LED ring displays the adjusted set and reset points, alternatively it can be adjusted as trend display. The LED display indicates the current measured value. The user can select between different display units. In combination with the two touch fields, the alphanumeric display is also used for a menu-guided parameter setting of the unit. Thanks to its rotatable display, the manometer can also be mounted in difficult installation situations such as upside-down mounting.

6. How do you reliably set optimum ingress resistance on the connectors of the ecolink series?
Answer:
The integrated end stop reliably protects the O-ring against excessive pressing. This excludes mounting errors caused by tightening the nut too much. The need for mounting by means of an expensive torque wrench that is difficult to handle is eliminated. The vibration protection of the nut is implemented using a saw tooth contour on the integrated metal sleeve. With this measure the connector is easy to mount and at the same time it protects the nut against unintended loosening, e.g. in cases of strong vibration in the installation.

7. What temperature sensors can be connected to the TP3xxx transmitter plug (head transmitter)?
Answer:
The unit detects the connected sensor type and configures itself accordingly. The following temperature probes can be connected:
a. temperature sensors of types TM, TS, TT. b. RTD resistance thermometers (Pt 100 or Pt 1000).

9. What can I do with ifm's modular mounting set?
Answer:
ifm offers a wide selection of accessories for installing and aligning sensors based on a clamp which is fastened using only a single screw. The sensors are kept securely in position, at the same time they can be moved freely in all axes. The clamps can be mounted on rods and bars, on surfaces and common industrial aluminium profiles.

10. Do I use a diffuse reflection sensor, a retro-reflective sensor or a through-beam sensor?
Answer:
  • A diffuse reflection sensor is used if a photoelectric sensor is to detect an object directly.
  • Retro-reflective sensors with polarisation filter are used for reflective objects. The polarisation filter enables reliable detection.
  • Through-beam sensors are the most reliable option for detection. If the installation position allows, the interruption of the light beam between transmitter and receiver ensures maximum reliability in operation.

11. How do I find the right installation location for the efector octavis vibration sensor?
Answer:
Only install the octavis in a thick housing wall and vertically to the machine surface using the spacer in the direction of the strongest vibrations. This is usually the radial direction.

More details in chapter 5 of the installation instructions

12. How do I use and update the FDT container?
Answer:
Software installation can be carried out from the CD (order no. E30110) or from the ifm download area

Here, you will also find drivers for Windows 7 (32/64 bits). A new download is necessary to update the device drivers (DTM). If the FDT software is already installed, only the DTM will be updated. After installation the new device drivers have to be updated in the library. To do so, press the "Update " button in the device selection wizard.

13. How many read/write heads can I connect to the DTE100 RFID evaluation unit?
Answer:
Up to 4 read/write heads can be connected to the DTE100 RFID evaluation unit .

14. How do I calculate whether the flow sensor functions with the available flow rate?
Answer:
Using the free ifm service tool the flow velocity, the flow rate or the inside pipe diameter can be calculated quickly and easily.

15. How do I set up a TCP/IP connection to ifm sensors using the Ethernet interface (O2D, O3D, O2I, VSE)?
Answer:
Connect, for example, the cable E11898 between the PC and the ifm unit. Under Control Panel/Network Connections a LAN connection is set with the IP address 192.168.0.10 as client.

The software allows the network to find the connected sensors. The connection is set up via a mouse click.

17. What do I use the O2D contour sensor for and what do I use the O2V pixel counter for?
Answer:
The object recognition sensor O2D is used in applications where defined contours are to be recognised.

An O2V object inspection sensor is used for variable contours.


18. Can I also connect ifm light grids or light curtains to the AS-i bus and how do I do this?
Answer:
Using the module AC007S ifm light grids and ifm light curtains can be connected to the AS-Interface bus.

19. Is it necessary to check ifm fail-safe sensors?
Answer:
A recurrent test as needed, for example, for mechanical contacts is not necessary because the sensor is self-monitoring. However, please note the maximum service life of the sensors. If the service life is exceeded, the probability of a dangerous failure is higher. For ifm fail-safe sensors the maximum service life therefore corresponds to the test interval.

20. Can I connect safety-related clocked sensors to evaluation units from competitors?
Answer:
Yes! You will find connection examples in the download area of the ifm web site.

21. What type of lights are allowed for use as muting lamps with the safety relay G2001S?
Answer:
The safety relay G2001S has a "current sense" (= current monitoring). Therefore you need a minimum current consumption. The right resistance value can be 820 ohms to 10 k ohm. Apart from the usual muting lamps (24 V DC / 0.5 to 5 watt) it is also possible to use LED lights if the consumption corresponds to the mentioned values.
