LINK Systems System 2500 PLS - Manual (Page 6)

System 2500 Operating & Installation Manual - Revision 07 1-2
A stroke counter and presettable batch counter, parts counter, and quality check counter
are standard.
One hundred setups can be stored in nonvolatile memory and recalled by job number or
name. Each setup can contain as many as 60 setpoints or dwell times for PLS outputs
along with complete programming information for each die protection input.
A sturdy, compact single resolver unit is used by the System 2500 as position transducer.
Motion Detection to detect resolver de-coupling from the machine shaft is standard.
Programmable offset capability to align resolver zero with machine zero is standard.
The Operator Interface Terminal (OIT) includes user friendly keyboard programming
with LCD display menus and prompting.
The System 2500 PLS displays angle and speed in 1 degree and 1 rpm increments.
The System 2500 PLS can operate at speeds up to 2000 rpm with solid state outputs.
1.2 Components
The System 2500 consists of three major components interconnected by cabling (see Figure 1).
These components are:
C Logic Unit - This is the primary component of the system which contains the
power supply and most of the electronic circuitry. Connections are provided on
the Logic Unit for wiring both the outputs (such as limit switch relay contacts)
and inputs (such as the die protection sensors).
C
Operator Interface Terminal (OIT) - This component is a panel mounted unit
consisting of a keyboard and two displays. The OIT allows the operator to
program the System 2500.
C
Resolver Unit - This is the position transducer for the system. It mounts on the
machine and is coupled to the crankshaft. The Resolver Unit reads the crankshaft
position and provides it to the Logic Unit.
