The Stack Light consists of a stack of four (4) colored lights: Red, Amber, Blue and Green (Top to Bottom). The stack light is situated to be reasonably visible from the circumference of the machine. The warning horn will produce a sound loud enough to be heard in a production environment while standing near the circumference of the machine.
The stack lights and warning horn have following meanings:

Warning Horn: The Startup Warning horn will sound for three seconds prior to the actual energizing or startup of a machine, which includes the enabling and recovery of servo powered systems.
The operator is required to push and hold the start button for the entire duration (three seconds) of the warning horn. If the operator releases the start button prior to the end of the horn, the machine will not start and the horn will cease to sound. The horn cycles on and off every ½ second for the duration of the alarm.
The Fault Warning alarm will sound when a fault exists and has not been acknowledged. The alarm will cycle on and off every 0.2 seconds until the fault has been acknowledged.
