System 2500 Operating & Installation Manual - Revision 07 2-19
The operator can use the cursor to select a data value, then key in the proper value and press
ENTER. When a 'down arrow' symbol is displayed as the last character on the bottom line of the
display, this indicates that another data line is available to the operator by pressing the down
arrow key while the cursor is on the bottom line. In the same way, an 'up arrow' symbol
displayed as the last character on the top line indicates that another data line is available by
pressing the up arrow key while the cursor is on the top line. Using the arrow keys the operator
can access both lines of data which must be entered. (NOTE: The MAX SPEED and MIN
SPEED shown on the top line of the first screen are for display only and cannot be entered on the
PLS Output Speed Advance screen. To change the value of MAX SPEED the operator must go
to the MOTION DETECTOR data screen, Section 2.5.2. To change the value of MIN SPEED
the operator must go to the TOPSTP ADVAN data screen, Section 2.5.4).
Both setpoint angles for Output Speed Advance must be entered for proper operation. The data
must be entered correctly or an error will be generated. This means that the angle entered for
maximum speed must be a smaller number than the angle entered for minimum speed (must
occur earlier in the stroke). After all data has been entered, programming of Output Speed
Advance is complete. Thereafter any PLS setpoint which is programmed as advanced (see
Sections 2.4.1.5) will be adjusted according to this data. For example, as the speed increases an
'on' setpoint will actually turn on earlier in the stroke than the angle that is programmed. Since
this function is for advancing programmed setpoints, any setpoint to be speed advanced should
have its angle programmed for proper operation at minimum machine speed.
WARNING: PLS OUTPUTS OF THE SYSTEM 2500 ARE NOT TO BE USED AS THE
PRIMARY INPUTS TO A PRESS CONTROL.
2.6 COUNTERS
The System 2500 PLS has four counters: Part Counter, Batch Counter, Quality Check Counter,
and Stroke Counter. To access the counter routines the operator must select COUNTERS from
the Main Menu. From the Counter Menu the operator may select any of the four counters.
2.6.1 PART Counter
The part counter is used to count the number of parts of a run. From the part counter display the
operator can view the current part count, the part count limit and the part counter status (active or
inactive). If the part counter is inactive, the count will not change. If the part counter is active,
the count will increment in one of two ways:
1. If a Die Protection input is programmed to act as a Part Detector (either 1 Part or 2
