Frequently Asked Questions - 797.90 Paulmann
How do I install the Paulmann 797.90?
Disconnect the power supply. Connect the module according to the wiring diagram provided. Mount it securely with screws or adhesive (if surface mount). Ensure the sensor lens is unobstructed.
What does the 'ON Threshold' mean?
The ON threshold is the light level (lux) at which the sensor activates. If ambient light is below this level, the module will turn on the connected light when motion is detected.
How does the timer reset function work?
The 3X timer reset means that if the sensor detects motion again within the off-delay period, the timer resets and restarts. After three consecutive resets, the module may behave differently (see flowchart).
What happens if I press the switch for more than 5 seconds?
Holding the switch for more than 5 seconds (ON >5S) will reset the module to factory defaults or enter a programming mode, as per the flowchart.
Can I use this module with LED lights?
Yes, it is compatible with LED lights up to 200 W. Ensure the total load does not exceed the module's rating.
What is the detection range of the sensor?
The approximate detection range is up to 8 meters with a 120° angle, but this may vary based on mounting height and environment.
How do I adjust the light sensor threshold?
Turn the potentiometer labeled 'LUX' (if present) using a small screwdriver. Set it to the desired brightness level where the module should activate.
Why does my light stay on continuously?
Check if the timer is set too long, or if there is continuous motion within the detection area. Also ensure the light sensor is not covered or set to a high threshold.
Can I use this module outdoors?
No, it is rated IP20 for indoor use only. Exposure to moisture may cause damage.
How do I clean the module?
Wipe the surface with a dry, soft cloth. Do not use water, solvents, or abrasive cleaners.
