Chapter 3 Initialization and Calibration
NOTICE
The Press Capacity and Calibration items on the Tonnage Monitor Initialization Menu are used
during the calibration procedure. Instructions for setting them are provided in
Adjusting AutoSetPAC To Read the Correct
Disabling/Enabling AutoSetPAC Parameters
The Tonnage/Waveform Initialization Menu allows you to enable or disable the following
AutoSetPAC functions:
•
Low setpoint
•
Repeatability setpoint
•
Setup mode
•
Startup counter
When you disable an item, that functionality is no longer available in AutoSetPAC. For example, if
you disable the low setpoint, the Low Setpoint field does not appear on Program and Run screens and,
therefore, cannot be set.
Low and repeatability setpoints are explained in
AutoSetPAC’s Setpoint Calculation Process
, page
93. The startup counter is discussed in
page
Setup mode allows you to operate the press in Inch without generating low setpoint or repeatability
faults. When Setup Mode is enabled, AutoSetPAC disables low and repeatability setpoints whenever
the press is operated in Inch. In order to be functional, Setup mode also requires that you wire a Setup
Mode circuit in SmartPAC (see Chapter 2 in your SmartPAC user manual). No special wiring is
required if your AutoSetPAC is being used with SmartPAC integrated with WPC 2000.
The high setpoint does not appear on this screen because the high setpoint cannot be disabled.
To enable or disable one of these items, do the following:
1.
Press ENTER with the cursor resting in the desired field until the setting you want is displayed.
The setting changes from ENABLED to DISABLED or from DISABLED to ENABLED each
time you press ENTER.
2.
Move the highlight bar to the next field and repeat step Press ENTER with the cursor resting in
the desired field until the setting you want is di.
Setting Reverse Setpoint % of Press Capacity
The SET REVERSE SETPOINT % item on the Tonnage/Waveform Initialization Menu allows you
to set the percentage that AutoSetPAC uses to calculate the high setpoint for “snap-through” reverse
tonnage. The reverse tonnage setpoint is calculated by multiplying the value you enter in this field by
the full-scale capacity of the press, which is also set on the Tonnage Monitor Initialization Menu (see
Setting Full-scale Tonnage on Your AutoSetPAC
, page 85). Press manufacturers typically recommend
that reverse loads not exceed between 15% and 25% of press capacity. Refer to the manufacturer’s
specifications to determine the correct value for your press.
Actual reverse tonnage values can be viewed in Run mode (see
