Overview
The SENSORWORX 4-button wall station provides an attractive and intuitive 0-10V dimming control solution for a low voltage sensor system. Many spaces now require by code (e.g., ASHRAE 90.1, IECC, Title 24) manual on, partial-on, or full range dimming user operation in addition to an occupancy sensor providing automatic off control. The simplest way of achieving this is by adding a low voltage dimmer that interfaces with the power pack controlling the room’s lighting. Adding a switch to a low voltage sensor system also enables users to override a space’s lighting off if necessary. Visually, the unit matches the SENSORWORX line of wall switch sensors and wireless remote wall stations, ensuring a consistent style across multiple spaces on a project. Additionally, the unit’s white LED indicator changes intensity as the dim level is adjusted and then changes to a blue location aid when lights are switched off.
Basic Operation
The SENSORWORX 4-button low voltage dimmer functions as a momentary switch with a pulse length of 250 msec. Typically, it is utilized along with any SENSORWORX power pack with the auxiliary switch input option (e.g. model SWX-900-AX, SWX-950-AX). Low voltage wire (typically 18 AWG) is used to connect the unit to the low voltage power, common, and relay status outputs from the power pack. The unit also has a momentary switch output that is used to signal the power pack. For applications requiring Vacancy (e.g., Manual On) operation, the switch signals the power pack to turn on lighting after the unit’s button is pressed. For applications configured for auto-on operation, the switch allows a user to override lights off regardless of occupancy. To achieve multi-way switching, adding a single button switch (model SWX-801) at each additional switch location is required. To facilitate dimming, the unit has a 0-10V output wire that is connected directly to fixtures. By default, the lights will always come on to the last dim level, however the unit can be programmed to turn-on to a preset level in order to accommodate partial-on applications.
Applications
A low voltage dimmer can be added to any space where 0-10V lighting is present. Energy codes require either Manual On or Partial On to 50% for many spaces such as:

Wiring Diagrams
Standard Wiring
MANUAL ON (VACANCY) OR PARTIAL-ON w/ FULL DIMMING CONTROL
- Lights turn on to last selected level (default) or to preset level (e.g., partial on).
- If no sensor is present, tie power pack low voltage red to low voltage white wire.
- Default operation of the SWX-900-AX is Automatic On (Occupancy) operation. For proper vacancy or partial-on operation, the SWX-900-AX’s OPERATIONAL MODE setting needs to be configured for MANUAL ON (VACANCY).
3-WAY, MANUAL ON (VACANCY) OR PARTIAL-ON w/ FULL DIMMING CONTROL
- Lights turn on to last selected level (default) or to preset level (e.g., partial on).
- If no sensor is present, tie power pack low voltage red to low voltage white wire.
- Default operation of the SWX-900-AX is Automatic On (Occupancy) operation. For proper vacancy or partial-on operation, the SWX-900-AX’s OPERATIONAL MODE setting needs to be configured for MANUAL ON (VACANCY).
- Only one SWX-804 dimmer can be included in 3-way configuration
Operation Settings
This dimmer has several dimming parameters that can be adjusted to accommodate different applications or user preferences.
LED Functionality
- The unit has one white LEDs that indicate the current dim level when lights are on (LED can be disabled)
- When lights are off, the LED changes color to blue as a location aid (can be disabled)
HIGH-END & LOW-END TRIM
- High-end trim enables energy saving task tuning by setting a maximum level (100%-50%) that which users are allowed to raise lights
- Low-end trim enables minimum user level of dimmer to be raised
TURN ON/TURN OFF DIMMING OPERATION
- Sensor turns on lighting to last user level or can be programmed to a preset level (100%, 50%, or custom)
- Sensor can turn off lighting by switching off power (by opening relay) or dimming below electronic off level
- Lighting can also be held at low-end trim level during unoccupied/off state
FADE ON/FADE OFF TIMES
- Adjustable time for level to ramp up to turn-on level (0.75 sec, 1.5 sec, 3 sec, 5 sec, or 15 sec)
- Adjustable time interval for level to ramp down to off (0.75 sec, 1.5 sec, 3 sec, 5 sec, or 15 sec)
DIMMING CURVE
- The dimming curve defines how the dimmer unit adjust its voltage output in response to button commands
- Linear (default), Square Log
