    Basic switch input module. No comms



    Sometimes all you need is a light switch.  The L2-SW module controls a Zone of lights by reading input signals from attached switches connected to the PDM Port, and creates a Channel signal on the PDM.  Up to 128 driver modules can listen to the Channel creating a group, or Zone, of lights.  The L2-SW can be “stacked” underneath any driver so both switch inputs and lights can be attached to the same PDM Port.  Perfect for closets and single-fixture rooms that require only one PDM port.  Only one L2-SW is allowed per Channel to create the PWM Channel signal.  The L2-SW also sends 12VDC Accessory Power from the Accessory Power Regulator (L2-APR) to the RJ45 Port through a protection fuse.  An L2-APR is required to power the microcontroller in the L2-SW.  Up to 16 L2-SW are powered by the L2-APR in the middle of the PDM.  The L2-SW is a low cost switch solution and does not communicate over the PDM comm bus.  Use an L2-DM if remote control or keypad input is desired.  Because the L2-SW uses the same LumenCache wall switches as the L2-DM, upgrading to the controlled L2-DM takes just seconds.  The L2-SW includes 6 Modes of operation to support all kinds of basic switch and button inputs.  It can read on/off, momentary, top/bottom switches, and occupancy sensing. The occupancy sensor enabled modes have setup macros allowing dimmed automatic restore based on occupancy detection, and can be overridden to full On by pressing a wall switch button.

    L2-SW SET button and indicator LED operation:

    The green LED indicator on the front face of the L2-SW indicates one of 6 Mode states (0..5) by flashing the Mode number, then a small pause, then repeating the cycle.  Wait for the pause and count the number of flashes to obtain the mode.

    Press the SET button on the face of the L2-SW to increment the Mode and cycle from 0 (solid LED indicator) to 5 flashes (Mode 5). Pressing the SET button when you see 5 flashes will return to Mode 0 (LED on solid).  


    MODE

    MODE NAME

    PORT DEVICES

    DESCRIPTION

    0

    Always OFF

    n/a

    Output zone channel remains OFF.  Ignores all switch inputs from the Port. Helpful during installation or when a channel needs to always be commanded OFF.

    1

    Normally Open Switch

    N/O door switch, Relay

    Sets zone to OFF when the switch input is shorted.  Sets zone to 100% when the switch input is open. Motion sensor will set output level to Motion Level. Used for toggle switches or automatic door pushbuttons. 4700k-ohm resistor in series with switch to allow occupancy features.

    2

    Normally Closed Switch

    N/C door switch, Relay

    Opposite action of Mode 1.  No occupancy detection. Turns on the zone when the input is an open circuit.

    3

    Button Toggle ON/OFF

    Buttons, L3-KP1, L3-TP1

    Toggles output between OFF and 100% each time the momentary button is released.   Top and Bottom buttons do the same function when using an L3-KP1.  No occupancy detection.

    (4)

    Top/Bottom Switch

    L3-WK1

    Two momentary buttons:  Tap the Top button to set output to ON. Tap the Bottom button to turn OFF the zone.  Occupancy detected will set output level to Motion Level if the light is Off. Occupancy ending will turn Off the output. Default mode.

    5

    Always ON

    n/a

    Output zone channel remains ON.  Ignores all switch inputs from the Port. Helpful during installation or when a channel needs to always be commanded ON.


    Tool-free commissioning using Configuration Macros:

    In addition to selecting the 6 Modes of operation, the SET button can be used to run configuration macros that store advanced settings.

    To Reset or Store values in the L2-SW memory, count the LED indicator flashes and set the current Mode to one of the modes in the table below, then hold the SET button for 6 seconds or until you see fast flashes. This will run the Configuration Macro as follows:

    SET button RESET/STORE functions (HOLD 6 seconds to perform configuration macros)
