Nexa Light Codes
Yellow/green repeated blinks
Just received power,-number of blinks corresponds to
program on UTM (3 blinks, pause, 3 blinks=revision 3.3)
Single yellow/green blink
Sensor triggered- dispense should occur immediately after
Low Battery Mode: Slow red blinking light (2.5 seconds
between) and still flashes yellow/green and dispenses when
hand is placed in sensor range.
Low battery indicator- Requires 3 sequential voltage readings
below the low battery threshold to turn on. Should have
1000+ dispenses remaining until shutdown mode will occur.
Red light will not turn off until dispenser is reset.
Shutdown Mode: Slow red blinking light (2.5 seconds
between) and dispenser does not dispense. When hand is
placed in sensor range, you will receive 3 quick red blinks.
Dead battery indicator- Requires 3 sequential voltage readings
below the dead battery threshold to turn on. Red light will
not turn off until dispenser is reset.
Timeout indicator- The dispenser will attempt to dispense for
10 seconds. If it cannot complete a single dispense cycle
(return to home position) after 2 dispense attempts, it will go
into shutdown mode the next time it is able to return home.
However, if after 5 dispenses, it has still not returned home, it
will also go into shutdown mode. This prevents unnecessary
wear on the gears and suggests the dispenser is jammed, has
very low batteries, or the battery cover is not fully secured.
Red light will not turn off until dispenser is reset.
**To reset dispenser- remove battery cover completely and replace
