System Setup & Faults
POWERING DOWN
Cause:
Occurs when the 120VAC that powers the
PressCam 8 is removed. Current data is
saved and system locks up to prevent data
from being corrupted.
Cure:
1) Check power input to Presscam 8.
Especially if you are using 24VDC. Your
supply may not be able to handle the
load.
2) Consult factory.
QUALITY CHECK LIMIT REACHED
Cause:
The Part Count fi eld reached the Quality
Count setpoint causing the Counter Output
to drop out.
Cure:
Push the Knob to reset in either RUN or
PROG modes. Part Count
fi eld will reset
to 0.
RELAY OFF S/B ON
Cause:
Output #15 or #16 relay detected off but
should be energized (on)
Cure:
1) Excessive electrical noise.
2) Bad relay.
3) Faulty circuitry.
RELAY ON S/B OFF
Cause:
Output #15 or #16 relay detected energized,
but should be off.
Cure:
1) Relay contact welded closed.
2) Excessive electrical noise.
3) Bad relay.
4) Faulty circuitry.
RESOLVER FAULT 1,2,3,or 4
Cause
: Hardware problem (1), jumping backwards
(2), jumping forwards (3), wrong voltage
levels (4)
Cure
: (same as before)
Check
: Unplug the 8pos connector from the PCB.
Expect about 21 ohms RED to BLK wires,
44 ohms GRN to BLK or WHT to BLK
wires.
SLAVE FAILURE
Cause:
The slave computer is not sending valid data
back to the master.
Cure:
1) Excessive electrical noise.
2) Computer failure.
SLV DATA or JOB FLT
Cause
: Data transfer between computers failed
Cure
: 1) Check for Electrical Noise
2) Check Job memory chip
3) Check Hardware
SPM > 999
Cause:
Unit is only designed to operate up to 999
SPM. If you are not operating outside this
range, then there is a fault in the system.
Cure:
1) The resolver is faulty.
2) Excessive electrical noise.
3) Computer failure.
TDC OFFSET FLT 1 or 2 (Top Dead Center)
Cause
: Master (1) or Slave (2) reports the OFF
SET does not match the other
Cure
: 1) Off-Line job programmer setup
incorrectly.
2) Faulty Job memory chip(s)
3) Electrical Noise
4) Faulty circuitry
TONNAGE BELOW MINIMUM
Cause:
Tonnage never rose above minimum during
the stroke.
Cure:
1) Connection from Load Module to
Presscam 8 is bad.
2) Minimum set too high.
3) Computer board bad.
4) Load module bad or needs calibration.
TONNAGE ABOVE MAXIMUM
Cause:
Tonnage above maximum during the stroke.
Cure:
1) Adjust your stamping pressure.
2) Maximum set too low for job.
3) Computer board bad.
4) Load module bad or needs calibration.
TONNAGE A/D FAULT
Cause:
Calibration input used by the computer is
not reading correctly
Cure:
1) Computer board bad.
