9.
Enter this observed maximum Clamp Open pressure (from SYS28)
into FOC42, SOC42, TOC42, and OSC42 (Pro-Set 600 addresses
N43:338, N43:398, N43458, and N43:518), the Clamp Open
Maximum Pressure Control Limits.
10.
While maintaining this maximum Clamp Open pressure, observe the
actual valve set-output value in the System Status Block
(SYS41-SYS44, Pro-Set 600 addresses N41:193-N41:196) that
corresponds to your selected Clamp Open pressure valve. Copy this
value into FOC44, SOC44, TOC44, and OSC44 (Pro-Set 600
addresses N43:340, N43:400, N43:460, and N43:520), the Selected
Clamp Open Pressure Valve Outputs for Maximum.
11.
Disable set-output by transitioning DYC01-B08 (Pro-Set 600 address
B35:392) from a 1 to a 0.
12.
Download your changes to the QDC module (refer to chapter 4 for
detailed instructions).
Test Your Clamp Open Pressure Valve(s) for Linearity
1.
Select pressure setpoints for Clamp Open that are typical of the
pressures you would run during normal machine operation. Enter
these setpoints into OPC10, OPC13, OPC16, and OPC37 (Pro-Set
600 addresses N43:546, N43:549, N43:552, and N43:573).
2.
Download changes to the QDC module (refer to chapter 4 for detailed
instructions).
3.
Jog your clamp to the full close position (mold halves mated).
4.
Enable First Clamp Open (DYC02-B10, Pro-Set 600 address
B35/410). The clamp should move from its start position through the
First Clamp Open profile, and then execute Open Slow. If no motion
is observed, check the following:
- Verify that none of your clamp or ejector overtravel alarms are set.
The QDC module inhibits clamp open if SYS07-B00 through
SYS07-B05 are set
- Verify that no programming error codes exist in SYS61 and
SYS62
5.
Upon completion of Clamp Open, observe the pressure reported back
for 1st clamp open segment 2 (OPS13, Pro-Set 600 address
N43:721). If the observed pressure is not approximately equal to the
setpoint entered in OPC13, then check:
- Was your valve and solenoid alignment the same for Clamp Open
profile execution and Clamp Open action in set-output?
