Appendix A Configuration Examples
This section of the manual will go though an example setup of each kind of system on a “typical”
press. Each example assumes that the hardware installation has been completed and the system
is ready for configuration.
The following examples assume the access system is using “Key Only” mode as described in
Section 2. Other modes may require entering a user code to change certain parameters.
Section A.1 Example Counterbalance Configuration
This example assumes the counterbalance system has been wired to the option board at “AS1".
First, some information needs to be gathered.
From the press counterbalance table mounted on the frame of the machine (or found in the press
manual), we find that at zero die weight, the counterbalance pressure should be 25 psi. The
maximum upper die weight for our example press is 7500 pounds. At that weight, the table says
the pressure should be 78 psi.
The pressure transducer installed on the system is a Setra model C209 that has a pressure range
of 0 to 200 psi and an output of 4 to 20 ma.
Now we go to the “Auto Sets” screen and with the RUN/PROG switch in PROG hit the
CONFIGURE softkey.
Since the counterbalance pressure transducer and valves are wired in at “AS1", move the cursor
to Air Slot 1. Press the CHANGE SETTING softkey. From the pop-up menu, select Counter-
Balance 1 by moving the cursor to Counter-Balance 1 and pressing the SELECT softkey. We
have now told the Automatic Setups module that Air Slot 1 is to control a counterbalance. We
must now configure all the parameters associated with Air Slot 1 for the particular counter-
balance and pressure transducer.
Press the CONFIGURE SYSTEM softkey. The Counter-Balance 1 Configuration menu will
appear.
Temporarily set the mode to OFF. We will change this after all other parameters are set.
Set the Display Weight As to lbs.
Set Max. Die Weight to 7500. This is the maximum capacity of the counter-balance per the
specifications listed above.
Set Min. Die Weight to 0. This is equivalent to have no upper die attached.
Set the Max. Pressure to 78 psi. Per the specifications listed this is the required pressure when
the maximum die weight is attached to the slide.
