PRETEST FOR SERVO FEED AND PRESS WITHOUT MATERIAL
Now that your servo feed unit has been mounted and the cables have been attached,
you can proceed with testing the unit. The first step is to turn on the main disconnect
switch on the electrical enclosure. Next, at the operator’s console, pull the power on-
off button to the on position. The button should illuminate to indicate that there is
power to the system.
The Pacific Scientific drive preforms an initiate sequence to check it’s internal program.
At this time the display should show the Rapid-Air screen for 5 seconds before starting
the main setup program. If you are comfortable with programming a job then continue,
if not, please refer to the “Programming Procedure” located in this manual.
Follow the programming sequence for the operators terminal to input parameters into
job storage. Your servo feed has been fully tested before it was shipped to your facility
and this procedure is merely a test to insure that all functions are still functional and the
cables are properly seated.
Once you have programmed the required parameters, select the manual mode of
operation. Check that the main air is at least 80 PSi and check that the roll pressure
gage is functional by adjusting the pressure up and down, This is accomplished by
turning the pressure adjusting knob. Open and close the feed and anti-backup rolls
electrically and or manually. Visually inspect that the rolls open and close as you press
the appropriate keys on the keypad or when using the manual levers.
Select the “inch” function (F2 on keypad) on the manual mode screen. Visually check
that the rolls rotate both forward and reverse with the corresponding key. The speed is
preset to creep the rolls at a slow speed for manual positioning of the material.
CAUTION: Do not attempt to place your fingers or any foreign material into the rolls.
Injury to the operator or damage to the servo rolls could result.
After you have verified that the rolls and air logic are operational, you can experiment
with the single cycle moves. The procedure is outlined in the programming section of
this manual.
Now, you can cycle the press and watch the rolls to verify that the signal from the
press window switch signal is functional and actuating at the proper time.
After all the checks have been made and you feel comfortable with the programming
of the servo controller, place the servo in automatic mode. Now cycle the press in
either the inch, single stroke or continous run, the servo feed should react upon the
closure of the press window and signal and simulate a feed progression of material.
