Description
Circuits
Operation
This is a micro switch that senses the lower limit position of the feed tray.
When the feed tray rises, the bracket disengages from the switch and the switch closes. When the feed tray
descends to its lower limit position, the bracket engages the switch’s actuator, opening the switch.
If the elevator encoder sensor does not detect
"photopassing
\
photointerrupting"
or
"photointerrupting
\
