4/6 Landis & Staefa Division
• Prior to commissioning, it must be made certain that the wiring is in compliance with
the plant diagram.
• The switch on and switch off delays for the control output must be set with the
respective potentiometers at the rear of the unit, as specified.
• The detector should be fitted to the power part without applying any force! When
fitting, the bar, terminal block and inscription can be used as orientation aids. To
avoid damage when fitting the detector, the bar on the detector and the terminal block
on the power part must face one another, with the inscriptions on both unit sections
mirror-inverted. Caution: Do not exert any pressure on the pyramid-shaped plastic
insert (optics) of the unit!
• After applying operating voltage or after fitting the detector, the unit will be switched
on for 1.5 min (initialization phase). This means that the contact of control output
Q23/Q24 will be closed.
• The switch on delay starts when the first movement is detected.
• The switch off delay starts after the last movement is detected.
• If the unit's detection zone shall be confined, the part of the detector that should not
monitor the space can be covered with adhesive tape that is impervious to light.
