Control Inputs - wattstopper BZ-2 Serie Manual De Uso

LOW VOLTAGE INPUTS
Four 5—30 VDC input wires are provided to control the load relay. The inputs may be used in combination or individually, depending on
the needs of the application. See the WIRING section for wiring information.

Control Inputs:

Control ON (Blue wire) – This input is intended for occupancy sensor input.
• Applying 5—30 VDC closes the relay in Auto ON Mode.
• Remove the voltage and the relay opens if no other input is holding it closed.
Hold ON (Orange wire, BZ-250/BZ-250-347 only) – This input is intended for timer or panel input.
• Applying 5—30 VDC closes the relay in Auto ON Mode.
• Remove the voltage and the relay opens if no other input is holding it closed.
• This overrides Control ON input.
Hold OFF (Brown wire, BZ-250/BZ-250-347 only) – This input is used for timer, panel, BAS or load shed input.
• Applying 5—30 VDC opens the relay.
• Remove the voltage and the relay can accept any other input.
• This overrides Control ON and Hold ON inputs.
Momentary Input:
Manual ON/OFF (Grey wire, BZ-250/BZ-250-347 only) – This input is for a low voltage momentary switch.
• Applying 5—30 VDC momentary input changes the relay to the opposite state.
• This overrides Control ON, Hold ON and Hold OFF inputs.
BI-LEVEL CONTROL
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.
