Re: [foxboro] SPEC200

Try Invensys tech support.  Invensys keeps the documentation on file for a long 
time.  If you system invovles using of ECEP then you need to identify its name 
and hunt each one down form Invensys.  Good luck.  I have worked on Spec 200 
when it first came out.  It is a very reliable system.  I have seen plant ran 
for over twenty years with very little problem other than occcasion replacement 
of a card.  Most problems are wires are too old and get brittle.  Or the 
cabinets are full of dusk due to infrequent opening - a manifest of how 
reliable this system is.
The Spec 200 is a modular base IC device.  All cards are designed based on the 
same principle.  The card which the IC is mounted on is insllated in a standard 
19 inch rack.  The system is built by directly wiring to the terminals in front 
of the card.  I/O points or control system is built by interconnecting wires.  
There are  both Analog and Digital type cards.  Controller tuning is via a set 
of screws mounted on the side of the card (you have to pull the card out to 
change the tuning parameters).

Many special application can be done by re-wring the card or changing its gains 
by adjusting its dial on the side.
