The Dimming Module controls a Zone of lights by reading input signals from attached switches or keypads 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-DM can be “stacked” underneath any driver so both switch inputs and lights can be attached to the same PDM Port.  Only one L2-DM is allowed per Channel to create the PWM Channel signal.  The L2-DM 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-DM.  Up to 16 L2-DM are powered by the L2-APR in the middle of the PDM.  L2-DM can receive commands and transmit their output status over the PDM communication bus to interface to third party control systems and the L2-EGW Ethernet Gateway.  Solving many more roles than just a dimmer for lighting, eleven modes of operation allow the L2-DM to read on/off, momentary, top/bottom switches, motion sensing, occupancy sensing, exhaust fan controls, ceiling fan controls, doorbells, and 1 to 8 button keypads.  No software or gateway is required for most configuration steps, even setting basic lighting scenes thanks to 1 button macros.  Advanced settings can be accessed using the L2-EGW.

L2-DM SET button and indicator LED operation:

The green LED indicator on the front face of the L2-DM indicates one of 11 Mode states (0..10) 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-DM to increment the Mode and cycle from 0 (solid LED indicator) to 10 flashes (Mode 10). Pressing the SET button when you see 10 flashes will return to Mode 0 (LED on solid).  


MODE

MODE NAME

PORT DEVICES

DESCRIPTION

0

Remote Only

n/a

Ignores all switch inputs from the Port. Only responds to serial data commands via the Comm Bus.

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. Used for toggle switches or automatic door pushbuttons.

2

Normally Closed Switch

N/C door switch, Relay

Opposite action of Mode 1.  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.

4

Top/Bottom Switch w/ Restore Level

L3-WK1

Two momentary buttons:  Tap the UP button to set output to Restore Level. Tap UP button again to set output to 100%. Tap the DOWN button to turn OFF the zone.

(5)

Top/Bottom Switch w/ Restore Level and Dim/Raise

L3-WK1

Tap the UP button to set output to Restore Level. Tap the UP button again to set output to 100%. Tap the DOWN button to set output to OFF.  Hold the UP button to raise output to 100%.  Hold the DOWN button to lower output to 1%.  Default mode.

6

Button Toggle ON/OFF w/ Dim/Raise

L3-KP1, L3-TP1

Tap to cycle between A)Restore Level, B)100%, and C)OFF.  Hold when output is below 50% to raise output level. Stops at 100%.  Hold when above 50% to dim output. Stops at 1%. Alternate mode is selectable via Gateway commands.  Top and Bottom buttons on an L3-WK-D respond the same to the tap feature.

7

Silent Follower

n/a

Ignores all switch inputs and responds to level replies from DM messages with the same ID. This mode does not send a reply message to a level change.

8

Keypad, Touchpad

L3-KP*, L3-TP*

Performs one of 4 functions responding to one of 8 keypad buttons being pressed.  Any of the buttons can A)Request a Scene, B)Toggle a Zone ID, C)Toggle a Scene on/off, D)Raise the last zone button pressed, or E)Dim the last zone button pressed. Buttons 1..8 can be spread across multiple attached keypads attached to the L2-DM in groups of 4.

Manually set and view the ID number:

Typically the ID #s will be assigned by the L2-EGW Gateway.  To manually assign an ID # of an L2-DM, Hold the SET button for 3 seconds and release.  Then tap the SET button the number of times of the ID. The green LED will flash each time you press the SET button.  Wait 5 seconds without pressing the button and the LED will remain solid for 2 seconds indicating the ID has been stored. To check the ID, hold the SET button for 3 seconds, release, and count the LED flashes.
