USER MANUAL KG0007 IFM

• Nominal sensing range (Sn) 8 mm (measured on an earthed metal plate and water; a shorter sensing range for other materials).

• Automatic adjustment to the medium to be detected. Installation Mount the unit by means of a mounting device. Secure it by means of the nuts provided so that it cannot work loose. Non-flush installation. Open space around the sensing face: Minimum distance when several switches of the same type are mounted:

setting button LED’s red, yellowElectrical connection Disconnect power before connecting the proximity switch. Connection strictly to the indications on the type label. Core colours: BN = brown, BU = blue. Adjustment The unit detects the "damped" state (= medium present) and the "undamped" state (= no medium present) and sets the optimum switch point.

The yellow LED flashes at 1 Hz (= unit is in the programming mode). Remove the medium and increase the distance between the medium and the unit until the red LED goes out. If the red LED flashes at 8 Hz, the interval between the "damped" and the "undamped" signals is too short. Press the setting button twice. The unit passes into the operating mode with the switch point being unchanged.

The yellow LED continues to flash at 2 Hz. The red LED goes out. Press briefly.

The yellow LED goes out briefly (= unit is in the operating mode). Place the medium into the detection area of the sensor and press the button briefly.

The yellow LED goes out briefly, then flashes at 2 Hz; In addition, the red LED flashes at 1 Hz Steps 2 and 3 can also be taken in reverse order: first align the unit without the medium being present and then place the medium into the detection area until the red LED goes out.If the setting of the switch point is not possible (the signals for damped/undamped follow too close), the red LED flashes after step 4 (= adjustment error). Press the setting button once. The unit then passes into the operating mode with the switch point being unchanged. Locking / Unlocking The unit can be electronically locked to prevent unwanted adjustment of the set parameters: Operation Check the safe functioning of the switch. The operation of the proximity switch is maintenance-free. For perfect functioning make sure that:

• the sensing face and the open space are kept free of deposits and foreign bodies, particularly for installation with the sensing face facing upwards. LED display:
