IV.
Calibration and Alignment
1.
Shafts, sprockets, and sensor points are permanently oriented to each other at the factory
2.
Alignment is set in the controller firmware
3.
The system counts pulses from the position sensors and encoders which are located on the
platters. The system stores these pulses in the hard drive.
4.
The number of pulses can be adjusted to center the bins.
5.
The calibration sequence resets the “home” position for the RoboCrib program to bin 111.
Note: If bins do not align correctly contact AutoCrib for instructions on fine-tuning the machine.

Bin Doors & Baffle Assemblies
1.
Bin Doors
a.
There are 15 levels.
b.
Each door has an LED indicator which light red when the door is sensed to be open or
unlatched.
c.
The doors are spring-loaded and are latched by a solenoid assembly.
d.
The doors will open after the fetch command has been completed.
e.
The doors have a safety switch interlock.
i.
Prevents the system from turning when a door is open.
ii.
The door switches can be over-ridden by moving the bin door bypass to
“Test”.
2.
Baffle Assembly
a.
The moveable baffles adjust according to the size of the bins.
b.
The baffle assembly is protected by a slide pot assembly that converts its absolute
position into a signal which is sent to the controller. This signal is used to position the
baffle doors and calibrate at start-up.
c.
The baffle assembly can be removed and replaced. (There are four screws on the
vertical Z channels and on ribbon cable connection.)
VI.
Wind Protection
1.
Mechanical Wind Indicator
The Wind Indicator is a bead on a spring-loaded string which is attached to the center
post of the main platter.
a.
The bead and string are housed in a clear vertical tube.
b.
The tube has markings which indicate how many winds from the zero position the
main platter has traveled.
c.
As the main platter turns, the string is wound around the center post. The bead rises
and falls accordingly.
d.
Wind Indicator only indicates the number of winds currently on Main platter.
2.
Model C RoboCrib
a.
An electronic wind indicator and restrictor are located on the Main platter and
LSP/Serpentine Chain.
b.
A 10-turn pot is driven by sprocket idler assemblies which are near the MP motor and
LSP motor.
i.
The pot translates the absolute position of the platter into a signal.
ii.
The signal is sent to a PIC chip in the RoboCrib controller.
iii.
This restricts the platters to no more than 2-1/2 winds from the zero position
in either direction (CW/CCW).
c.
The number of winds is indicated by LEDs on the controller.
