4. Align all other machine hydraulics to simulate clamp tonnage. For
example, if certain pumps are turned off during tonnage, turn them
off at this time. If a certain valve alignment exists during tonnage,
line the valves up accordingly at this time.
5. Enable set-output by transitioning DYC01-B08 (Pro-Set 600 address
B35/392) from a 0 to a 1.
6. Begin increasing the set-output word which controls pressure in 5%
increments while observing the clamp pressure (SYS28, Pro-Set 600
address N41:180). Stop increasing the value when the observed
clamp pressure is equal to the desired tonnage pressure for your
machine. If the desired pressure cannot be reached, evaluate your
settings for the other three set-output words, and verify they are set
properly.
7. Enter the resultant set-output values from DYC09-12 into LPC33-36.
These values are applied to your connected valves when the clamp
completes Low Pressure Close.
8. Disable set-output by transitioning DYC01-B08 (Pro-Set 600 address
B35/392) from a 1 to a 0.
9. Enter the desired tonnage pressure for your machine (step 6) into the
Tonnage Complete Pressure Setpoint (CPC63, Pro-Set 600 address
N43:299).
10. Download your changes to the QDC module (refer to chapter 4 for
detailed instructions).
Set Pressure Alarm Setpoints
After spanning your Low Pressure Close pressure valve, set your Low
Pressure Close maximum pressure alarm (LPC57, Pro-Set 600 address
N43:233) equal to a value you feel should not occur during Low Pressure
Close. Make sure this value is not greater than the Low Pressure Close
Maximum Control Limit (LPC42, Pro-Set 600 address N43:218). Entering
a value of 0 disables this alarm.

Procedure in chapter 4.
