Section 1 OVERVIEW OF THE SYSTEM 2500
1.1 Features
The System 2500 has 8 or 16 channel output capability for Programmable Limit Switch
functions.
Relay, solid state AC, and solid state DC outputs are available.
Multilevel programming security is provided so that fixed setpoints or special access can
be provided on the first 8 output channels.
Timed outputs up to 2 seconds in duration and speed advanced outputs are programmed
through the keyboard.
System 2500 PLS outputs 1 through 8 may be programmed so that they actuate only on
certain machine strokes.
The Die Protection function of the System 2500 has 8 inputs available to the operator for
use with die sensors and probes. These inputs may be used to monitor part ejection, stock
in place, material in position, stock buckling, end of stock, or other factors.
Each die protection input can be programmed for any of the following modes: Static,
Cyclic, Tracking, Transfer, In Position, Single Part detection or Two Part detection. A
special option of Cyclic mode enables the operator to activate a PLS output in the event
of die protection fault on this Cyclic input. This can be used for ejection of bad parts off
an assembly line or similar applications.
Eight internal timing channels are provided so that the operator can create timing
sequences for Cyclic, Transfer, In Position, and Part Detector modes.
The operator can select an output of either Emergency Stop (immediate stop) or Top Stop
for each die protection input monitored.
The System 2500 includes outputs for providing power to external die protection sensors
and also includes a separate power source for Link Model 3040 and 3080 parts detector
units.
As an option, the unit can be programmed to use the die protection inputs and the PLS
output relays in conjunction with an external control package to provide a complete
system for implementing the Automatic Single Stroke function.
