resses with of the “DOWN” pushbuttons. The
operator must hold the pushbutton for three sec-
onds. During this time, the motion alarm will flash
and beep. After holding the pushbutton for three
seconds, the machine will tilt the enclosure back
to the “PRS4” switch.
If the machine was at either the “PRS3” or
“PRS4” switches the “DOWN” button doesn’t
have to be held on. The machine will lower to the
“PRS4” switch, wait for a half second, and then
the enclosure will lower to the “PRS2” switch.
If the machine is not at the “PRS3” or “PRS4”
switches, the operator will hold the “DOWN” but-
ton until the machine reaches the “PRS4” switch,
release the “DOWN” button, and then press it
again for three seconds to start the machine
lowering to the “PRS3” switch. Once the motion
starts, the operator does not have to hold the but-
ton. The motion alarm will continue to flash and
beep as long as the machine is in motion.
Notes:
If Photo Eye is obstructed at any time, all motion will
stop and the “GUARD RESET” pushbutton light will
turn on. No motion can occur until the operator has
cleared the obstruction and pressed the “GUARD
RESET” pushbutton.
If the E-STOP or STOP is pressed, the op-
erator must perform steps 2, and 3 to resume opera-
tion.
Run Time Fault Sequence
1. If any motion takes longer than 20 seconds, a Run
Time Fault has occurred. The fault could be caused
by a tripped overload relay, blown fuses, damaged
hydraulic lines, faulty valve, damaged wiring, or a
damaged or faulty proximity switch.
2. Once a run Time Fault is detected, all machine
motion stops, and the lighted “GUARD RESET”
pushbutton will flash. Qualified personnel should
examine and check the machine for the cause of
the problem before it is returned to operation. After
the problem has been corrected, the machine can
be reset by turning the “MANUAL/AUTO” switch to
the “MANUAL” position and pressing the “GUARD
RESET” pushbutton for 5 seconds. The light will
turn off, and machine operation can be resumed.
Manual Mode
There are two uses of the “MANUAL” mode.
1. To stop and correct and automatic motion started
in error. Turning the “MANUAL/AUTO” switch to
the “MANUAL” position will stop the automatic
motion. The machine can be manually operated
with the “UP” or “DOWN” pushbuttons to return
the machine to a particular starting position.
2. The second use is for qualified personnel to test
and diagnose problems with the machine by use
of the “UP” or “DOWN” pushbuttons.
