USER MANUAL KN5101 IFM

• Adjustable to the target medium by means of a programming but- ton or by an electrical signal on the function check output. Installation LED’s red, yellow, green push button Units of the type KNM30BSA... should be mounted into the ves- sel wall. The sensor is in contact with the target medium. Suitable for dry target medium. Units of the type KNM30NSA... should be mounted outside the vessel. The sensor detects the target medium through the vessel wall. Suitable for both dry and liquid target media. Only for non-metallic vessels.Electrical connection Disconnect power before connecting the unit. Connect according to the indications on the type label. Setting

• With target medium absent The setpoint is adjusted while the vessel is empty. When target medium is detected, the sensor’s output switches. The switch-on and switch-off points are automatically generated.

• With target medium present For most applications setting the sensor while the vessel is empty is suf- ficient. You can, if you wish, make an additional adjustment with the target medium present (e.g. to obtain an optimum excess gain for spe- cial applications). *You can adjust the setpoint via pin 2 (fc output). (signal length = duration of pressing the button) Type FPKG: (+U

) to pin 2; type FNKG: (-U

) to pin 2. Press the button and keep it pressed (5 ... 10s).* Now release the button. The green LED flashes slowly (approx. 1 Hz), after approx. 5s it flashes faster (approx. 2 Hz) (= unit is in the programming mode). The yellow and green LED’s are lit (= unit is set and is in the operating mode). Press until the green LED flashes (max. 5s), then release the button.* LED green flashes (= unit is in the programming mode); after a short time the green LED lights (= unit is set and is in the operating mode).

2The setpoint values made with an empty vessel are not overwritten by automatic setting while the vessel is full. You can update adjustment with the vessel full as often as you wish. (Automatic setting with the vessel full will return the “full“ setting to the factory default.) If adjustment is not possible (e.g. “empty“ signal strength and “full“ signal strength are almost the same), the red LED flashes after setting (in addition the function check output provides a 2Hz signal). Press the button briefly (= acknowledgement) and repeat setting. Locking / Unlocking: *You can also lock/unlock the unit via pin 2 (fc output). (signal length = duration of pressing the button) Type FPKG: (+U

) to pin 2. Type FNKG: (-U

) to pin 2. Press for at least 10s* Press for at least 10s*

At first the green LED flashes slowly, then faster. After 10s it goes out. The unit is locked. After 10s all LED’s go out for a short time. The unit is unlocked and the LED’s indicate the current operating status.Operation Check whether the unit functions properly. Indication by LED’s and by the function check output: LED green unit is ready for operation LED yellow lit = output is switched flashing = output is short-circuited LED red
