5. Enable set-output by transitioning DYC01-B08 (B34/392) to 1.
6. Change the set-output word DYC09-12 (N40:121-124) corresponding
to your clamp tonnage (lock-up) pressure valve in 5% increments
while observing clamp pressure (SYS28, N40:180). Stop changing it
when the observed clamp pressure equals the desired tonnage
pressure. If you cannot reach the desired pressure, verify that the
other three set-output values are correct.
7. Copy the resultant set-output values from DYC09-12 (N40:121-124)
into LPC33-36 (N43:209-212). The QDC module will apply these
values to the valves when the clamp completes low pressure close.
8. Disable set-output by transitioning DYC01-B08 (B34/392) to 0.
9. Enter the desired tonnage pressure for your machine (step 6) into the
tonnage complete pressure setpoint CPC63 (N43:299).
10. Download your changes in LPC and CPC to the QDC module.
Important: If downloading from your programming terminal, download
LPC followed by CPC with download bits B21/5 and 6 (chapter 4).
Set the Profile Pressure Alarm
Set your clamp LPC maximum pressure alarm LPC57 (N43:233) to a
pressure that should:
not be exceeded during the clamp close profile
not exceed the maximum pressure control limit LPC42 (N43:218)
Entering a value of zero disables this alarm.
Download the alarm setpoint to the QDC by downloading the LPC and
CPC blocks.
Important: If downloading from your programming terminal, download
LPC followed by CPC with download bits B21/5 and 6 (chapter 4).
