Page 4: System Overview And Range Of Applications
System Overview and Range of Applications System Overview SCAN light curtains consist of a transmitter and a receiver. Like a light barrier, they work with modulated infrared light and stand out due to the following features: • Measurement field up to 6 m wide, from 900 to 3000 mm high •... -
Page 5: Range Of Applications
Range of Applications The scope of SCAN applications ranges from simple detection or measuring tasks, such as controlling projection or the presence of an object, to contour or shape recognition. Overhang control Customer machine Measuring of widths control Loop control... -

“light path interrupted”) is output either as an aggregate signal at the switch output or as a single measurement value within a serial data stream via the RS 485 interface of the receiver. Display Elements SCAN SCAN transmitter receiver Vor Anschluss Vor Anschluß... -
Page 8: Rs 485 Data Interface
The signal statuses of the individual light axes (“light path unobstructed” or “light path interrupted”) are transmitted as a serial data stream over the RS 485 interface. The transmission takes place in half duplex mode at 19.200 baud in the Leuze lumiflex- specific protocol described below. -

The individual light axis are made available to the user bit-by-bit beginning at memory position VB20 (1 = light, 0 = no light), continuing from the first light axis (at the SCAN connection) to the last light axis (at SCAN´s free end). -
Page 10: Contamination And Error Signal Output
This pnp output normally carries +24V DC. In case of a weak receiver signal caused by contamination or misalignment, or in case of a fault, this output is switched to high resistance. The output is short-circuit-proof and can carry up to 70 mA. SCAN... -
Page 11: Mounting
Mounting Standard Mounting SCAN units are mounted by means of through holes in the profile end pieces. (For the distance between holes, see the dimensional table on page 17 and the dimensional drawing on page 18.) The holes have a diameter of 5.3 mm. -
Page 12: Mounting Scan With The Protective Mounting Profile
Mounting SCAN with the Protective Mounting Profile To provide additional mechanical protection, the SCAN can be snapped into a protective mounting profile. This is recommended for larger measurement heights and when the units need to be adjustable. The protective mounting profile can be used with either a standard mounting bracket or a swivelling mounting support with vibration damping.. -
