WARNING
Flashing Red light on Light Stack
•
Green Light
–
A green light indicates power has been applied to the controller, and the system is in normal
operating mode.
–
This light turns off when there is a fault or when in bypass mode.
•
Amber Light
–
The amber light flashes when the slowdown limit switch is triggered, or the distance measured with
the laser indicates the trolley or bridge motion has crossed into a slowdown area. The amber light
changes to steady state if the stop area is entered.
–
The amber light is turned off when in normal operation outside of a No-Fly zone.
•
Red Light
–
The red light turns on when a fault occurs in the controller or laser, or when the protected zone is
breached. The red light stays solid red until a breach or other fault is cleared. In this state all
control is stopped until the fault has been cleared.
–
The red light also flashes if no zones are configured such as on initial startup. In this state the red
light will flash until at least one zone is enabled.
–
The red light is turned off when in normal operation outside a No-Fly zone, and when there is no
fault with the lasers or controller.
