Altering the WARN and FAIL Set Points
1. Insert the maintenance key and turn the keyswitch
from RUN to PROG (enter the password when
asked).
2. Turn the Knob until the WARN fi eld is highlighted.
3. Push the Knob and enter in the new value (one
digit at a time, left to right).
4. Do the same for the FAIL fi eld.
NOTE: Since there is only one FAIL set point, it
should be the worst case value for all the die and
speeds used.
Motion Detection: The PressCam 8 needs to see
motion within the time period selected or a fault will
occur (lack of motion). Set this value to the minimum
value that does not generate a fault. This will enable it
to detect faults faster.
Drift Detection: The PressCam 8 has built in Drift
Detection. If the press starts to move without a brake/
clutch signal, a drift fault will occur. The threshold is .2
spm and cannot be user altered.
90° Stop Test: Inch the press up to top. Select this
feature and press the Knob. Now, run the press. The
PressCam 8 will shut down when the press reaches
90°. The press will come to stop at some point after.
This shows the worst case stop time.
Servo Setup
Interface. Output of data is via a RS-232 DB-9
connector located on backside of LCD screen. 9600
Baud, 8 bit no parity, 1 stop bit.
The PressCam 8 can be confi gured for either DCE
(standard; J6 & J7 jumpers horizontal) or DTE (optional;
both jumpers removed and installed vertical, straddling
both J6 & J7).
PressCam 8 DB-9 pin out (DCE confi guration):
1 DCD 2 TX, TO SERVO
3 RX, FROM SERVO 4 DTR
5 GND 6 DSR
7 RTS 8 CTS
9 NC
(DTE confi guration reverses pins 2 and 3)
The only pins used by the PressCam 8 are 2,3,5. Pins
1,6,8 are tied to +15V, and Pins 4,5,7,9 are tied to
ground.
Each PressCam 8 job stores individual Servo Setup
information and outputs thru the RS-232 every time the
unit is powered up (after the Knob is pushed), after you
exit from the Servo Setup screen, and after a job change.
The Servo Setup screen can be accessed only while in
PROG mode.
