4.1.2 ESI Interface Board Explanation
Goes out when upper-limit switch is tripped
Goes out when lower-limit switch is tripped
Goes on when power to running surface break is applied; not currently in use
Goes on when elevation motor is going down; when elevation motor is plugged in, both
LED 4 and LED 5 light up when elevation motor moves in either direction
Goes on when elevation motor moves down
When light is on, drive board is disabled and running surface will not lock
Goes on when 5 V (volts) is supplied to isolated interface board circuit; if light goes out,
drive will not speed up, display will turn on, and elevation can change
Goes on when 12 V supply properly signals to drive to increase speed
Flashes with each pulse from encoder through drive board; speed signal coming back
from drive
Goes on (dim) once device reaches speed of 8 MPH (13 km/h); LED gets brighter as
device speed increases; hooked into 12 V analog signal to belt drive for forward motion
Similar to LED 10, but for reverse analog signal; light never goes on (reverse mode can
only reach speeds of up to 5 MPH [8 km/h])
5 V supply for non-isolated interface board circuit; if no light, display registers an error
