Frequently Asked Questions - KI5209 IFM

What is the supply voltage of the KI5209?

The KI5209 generally operates under a DC voltage of 10 to 30 V DC. Check the label on the device to confirm.

How to adjust the sensor's range?

Use a screwdriver to turn the potentiometer on the device. Turn clockwise to increase the range, counterclockwise to decrease it.

How to program the output as normally open (NO) or normally closed (NC)?

Programming is done via a shunt in the connector. Shunt closed = NO (as delivered), shunt open = NC. For type KGE, programming can also be done via wiring.

What does the yellow LED on the sensor mean?

The yellow LED indicates the output status: on = output active (object detected), off = output blocked.

Can the sensor be mounted flush?

Yes, but the range may decrease. Respect the free zone around the active face. For flush mounting, use a sensor designed for this purpose.

What materials can the capacitive sensor detect?

It detects non-contact metals, plastics, glass, ceramic, wood, paper, oils, greases, water and all aqueous fluids.

How to connect the KI5209?

The device is supplied with a connector. Follow the wiring diagram on the label: pins for L+, L-, and output. Use a miniature fuse if necessary.

Is the sensor protected against short circuits?

Yes, IFM sensors have an internal pulsed short-circuit protection. After a short circuit, check proper operation.

How to maintain the sensor?

No regular maintenance is required. Simply keep the active face clean and free from deposits or foreign objects.

What to do in case of malfunction?

First check the power supply and wiring. If the problem persists, the device is not repairable and must be replaced. Dispose of it in accordance with local regulations.

Information

Supplementary note.

Safety instructions1

Please read the product description prior to set-up of the unit. Ensure that the product is suitable for your application without any restrictions.

The unit conforms to the relevant regulations and EC directives.

Improper or non-intended use may lead to malfunctions of the unit or to • unwanted effects in your application.

That is why installation, electrical connection, set-up, operation and maintenance of the unit must only be carried out by qualified personnel authorised by the machine operator.

Functions and features2

The capacitive sensor detects without contact metals, almost all plastics, glass, ceramics, wood, paper, oils, greases, water and all hydrous materials and indicates their presence by providing a switched signal.

Installation3

Notes on flush and non-flush installation3.1

In case of flush installation of non-flush units the sensor properties change and the sensor can remain permanently switched (loss of function).

Observe the free space around the sensing face.

The distances need to be determined by the user in his application.

Electrical connection4

The unit must be connected by a qualified electrician. The national and international regulations for the installation of electrical equipment must be adhered to.

Disconnect power.

Connect the sensor according to the indications on the type label.

Note: use a miniature fuse according to the technical data sheet, if specified. Recommendation: check the safe functioning of the unit after a short circuit.

It is not possible to repair the unit.

After use dispose of the unit in an environmentally friendly way in accordance with the applicable national regulations.

Definitions9

Active zone

Area above the sensing face in which the sensor reacts to the approach of the target.

Output function

Normally open: object within the active zone - output switched.

Normally closed: object within the active zone - output blocked.

Programmable: choice between normally closed or normally open.

Positive switching: positive output signal (to L-).

Negative switching: negative output signal (to L+).

Power-on delay time

The time the sensor needs to be ready for operation after application of the operating voltage (in the millisecond range).

Hysteresis

Difference between the switch-on and the switch-off point.

Leakage current

Current for the internal supply of 2-wire units, also flows through the load when the output is blocked.

Current consumption

Current for the internal supply of 3-wire DC units.

Switch point drift

Shifting of the switch point owing to changes of the operating conditions (e.g. temperature, pressure, air humidity).

Short-circuit protection

ifm sensors which are protected against excessive current by means of a pulsed short-circuit protection. The inrush current of incandescent lamps, electronic relays and low resistance loads may cause this protection to cut in and turn the sensor off!

Operating voltage

The voltage range in which the sensor functions safely. A stabilised and smoothed direct voltage should be used! Take into account residual ripple!
