Led Indicator - LEGRAND Wattstopper BZ-200 Instructions D'installation

The diagram to the right shows how to configure BZ-250
to provide bi-level lighting control with both Automatic ON
and Manual ON features.
As shown, upon occupancy detection load A turns ON
automatically. To turn ON load B, the user must press
momentary switch B. Both loads turn OFF automatically
when the sensor time delay expires, or manually using
switch A and B. If the sensor input re-triggers within 30
seconds after the load turns OFF, loads A and B turn ON
again. After 30 seconds expire with no sensor input, you
must press the switch to turn ON load B.
The BZ-2xx contains built-in short circuit and thermal protection circuitry that shuts down the +24 VDC output (low voltage red wire)
to prevent permanent damage to the power pack. Removing the excess load from the output restores the BZ-2xx to proper operation.
Connect the excess load to another power pack.
Output is current limited. As the load increases, the BZ output will reach its model-specific maximum output current. Under these
conditions, the output voltage may appear less then the nominal 24-V output and the BZ will indicate the overload conditions with a
continuously blinking LED (as described in the LED Indicator section). In extreme cases, such as a dead short, the output voltage will
appear near zero but will automatically return to normal operating conditions once the excess load is removed.
The LED on the left side of the BZ-2xx indicates the following conditions:
• LED OFF: no power to the BZ-2xx, or the +24VDC output is shorted.
• LED blinking continuously: current output limit is exceeded (too many sensors are connected to the power pack); +24VDC output
shut down.
• LED ON, blinks once every 3 seconds: the relay is open (load OFF).
• LED ON continuously: the relay is closed (load ON).
The lights came ON automatically after I deliberately turned them OFF for a presentation.
• The BZ-2xx is set for the Auto ON Mode and the occupancy sensor time delay expired. The BZ-2xx reverted to Auto ON and then
motion was detected.
▸ Consider increasing occupancy sensor sensitivity and/or time delay.
▸ Generate more motion during presentations.
The load does not turn ON with occupancy detection.
• Mode Switch is set to Manual ON.
• Hold OFF input is active.
