Function Description
Press Utility
This function has six sub-functions that can only be
accessed in PROG mode and the J5 access plug is
removed (located on the backside of the LCD).
Set Password (SETPAS): The operator enters a three
digit number to be used as a password when the key
switch is moved from RUN to PROG mode. Set to 000
to turn off the password feature. If you forget your
password, contact the manufacturer.
Clear JOB (CLRJOB): Erases the entire currently
selected job. You must hold in the knob for two seconds.
Clear DATA (CLRDTA): Erases data from the current
selected job but keeps the name. This prevents the
system from automatically copying data from another
existing job.
Clear ALL memory (CLRALL): Warning! Erases ALL
memory of unit entirely. You must hold in the knob for
two seconds. The lower left corner of the LCD should
now tell you that its “Powering Down”. You must cycle
power to the Presscam 8. When you power up, you will
notice “Cleaning Memory” in the lower left corner of the
LCD, wait until the normal screen reappears (about 1
minute). You must reset the Top Dead Center for this
unit over again.
Top Dead Center (SETTDC): This allows you to zero
the press when the Ram is at TDC. Start by inching the
press up to TDC. Then hold in the knob for fi ve seconds.
WARNING: This function should only be used
during installation or when hardware changes.
Never change TDC to fi x a timing problem or any
other problems with limit switches.
Remote Status (Remote): This allows J8 RS-232
serial port to be used as a Remote Status output port
“RMT ON”, or allows the use of the External Ethernet
board Option “TCP ON”, or for the Servo Control out-
put “RMT OFF” (default). (See page 24 for details)
Language Selection (English / Spanish / French):
This changes text between languages.
Now you should have a correctly operating press running
at minimum speed.
4. Cycle the press at maximum speed. Note the
angle where it stopped. Enter the angle at which
the press came to a stop (something past 0º in the
Speed Compensation fi eld. If the press came to
a stop at 30º, then enter this value into the fi eld.
5. Go back to the Limit Switch Setup screen and
turn on Speed Compensation for top speed signal
outputs (usually LS1 and LS2) by selecting the “*”
in the “sp” column.
6. Operate the press at maximum speed again
and check for proper stopping position. Adjust
the Speed Compensation angle (up or down)
accordingly to force the press to stop on top.
7. Go back (one more time) to the Limit Switch Setup
screen and select all the LS outputs you wish to
have speed compensation on by selecting the “*”
in the “sp” column.
WARNING: Some outputs must not be
compensated. An example would be Auto Return
/ Mute Out Limit Switch (usually LS3 or LS4).
WARNING: If the press is stopped during a normal
cycle (not at top stop), it is possible that a Speed
Compensated Output will trigger again as the press
starts to move again to fi nish the current cycle. This
is because you are now starting from 0 SPM and
the stopped press location may have not reached
the true output angle for the compensated output.
If you are using a servo feed initiate, you may have
to turn it off before you return back to top stop to
prevent a possible double feed.
