Proximity Switch
The low limit proximity switch (641) is located near the
air cylinder (mounting plate (15) and can be adjusted to
operate at different levels in the bin. See F
IG
. 13.
The pumps operate in fast mode until the ram plate
reaches the low limit. The proximity switch changes the
pumps to the slow mode operation for a user selected
amount of time, after which the pumps stop, the seal
deflates, and the ram raises.
The system timer controls how long the pumps run at
slow speed at the end of bin evacuation. After the time
elapses, the controller stops the pumps, deflates the
seal, and raises the ram up.
NOTE:
See

mation on adjusting the proximity switch and system
timer.
