DWL Quick Reference

DWL Detailed Reference

On power up all Lights (item 2) on the Driver Warning Light (DWL) will blink 3 times.
Once communications are established with the control box The DWL “Binding Icon” will turn on (item

5).
Signal Icon will appear above the “Binding Icon” icon and will be updated continuously for the first 10

minutes after each power on for determining signal strength from the control box (item 4).
During Normal Operation the lights will be off and the LCD will read “0” in the system status section

(item 6). The DWL cannot respond to flow events if we are not in this state.
If no communication has been received from the control box the LCD will read “1” in the status section

(item 6) until communications with the control box are established which can take as long as 2 minutes
after a new install but is typically less than 10 seconds.

If no pressure exists at the control box the DWL system status will read “2” (item 6).
On a low flow event that has lasted at least 10 seconds the corresponding wheelend light will turn on

continuously (item 2) and the display will show a yellow persistent block at that wheel end location
indicating flow occurred on this trip (item 3). When the flow event goes away the light will turn off but
the yellow block will stay on without power until the next power up event.

On a high flow event that has lasted at least 10 seconds the corresponding wheelend light will begin
blinking (item 2)and the display will show a yellow persistent block at that wheel end location
indicating flow occurred on this trip (item 3). When the flow event goes away the light will stop blinking
but the yellow block will stay on without power until the next power up event.

If the system detects that repeated or severe flow events are occurring and the system the “service
alert icon” will turn on and stay on until the system is repaired (item 1). The service alert indicator will
clear itself after 1-2 days of good conditions on that wheel end. A Stemco HandBat can also be used to
clear the service event manually if desired.
