Operational Sequence
1. Operator turns rotary disconnect switch to ON.
The red “E-STOP” pushbutton light will turn on.
2. Operator pulls or releases “E-STOP” pushbutton
in the door of the control panel or the “STOP”
pushbutton on the remote pushbutton station. If
additional E-stops have been added, these also
have to be released.
3. Operator presses the “E-STOP RESET” pushbut-
ton. The “E-STOP” pushbutton light will turn off,
the green “E-STOP RESET” pushbutton light will
turn on, and the “GUARD RESET” pushbutton
light will turn on.
4. Operator turns the “MANUAL/AUTO” selector
switch to the “AUTO” position.
5. To operate the machine the amber-lighted
“GUARD RESET” pushbutton must be pressed.
If the photoeyes are clear the “GUARD RESET”
pushbutton light will turn off. The machine is
ready to operate.
6. Operator places a container inside the enclosure
and sets the retention bar. This process will dis-
rupt at least one of the Guard Photo Eyes.
7. Operator leaves the enclosure and presses the
“GUARD RESET” pushbutton. If the photoeyes
are clear the “GUARD RESET” pushbutton light
will turn off. The machine is ready to operate.
8. Operator presses one of the “UP” pushbuttons.
The operator must hold the pushbutton for one
second. During this one second, the motion
alarm will flash and beep. After holding the push -
button for one second, the Enclosure rises to the
“PRS1” proximity switch and stops. The operator
does not have to hold the button during this first
stage of motion. The alarms will continue to flash
and beep as long as the machine is in motion.
9. To tilt the enclosure and dump the contents, the
operator must press and hold one of the “UP”
pushbuttons until the machine has tilted to the
desired position. The operator must hold the
push button for three seconds before the ma-
chine will start to tilt. During this three seconds,
the motion alarm will flash and beep. If the opera -
tor releases the “UP” pushbutton, the machine
will stop movement, and the operator will have
to hold the pushbutton for three seconds before
the machine will tilt again. This prevents rapid
jogging of the machine. This process may be
repeated until the tilt frame reaches the “PRS3”
proximity switch.
10. If the enclosure is not at the “PRS3” or “PRS4”
proximity switches, the “DOWN” pushbuttons can
be used to tilt the enclosure down without return-
ing the machine to full down. The operator must
hold the pushbutton for three seconds before the
machine will start to tilt. The machine will stop
when either the “DOWN” button is released, or
the “PRS4” proximity switch is reached.
