3.1.3 DETACHABLE TERMINAL BLOCKS

WARNING - ALWAYS CHECK TERMINAL LOCATION AND
ORIENTATION
All connections, except the Ac power supply, are made on removable
terminal strips. Terminal strip removal is achieved by removing the
retaining screws and pulling them directly away from the front panel. The
terminal strips must be carefully installed in the correct position and not up
side down.

3.2.1. STATION NUMBER (STN)
Four bit switches (Switch 1 - Switch 4) are provided on the SYSTEM 32 to
select controller addresses. These are read in hex format providing 16
addresses, 0000 to 1111. The base Station Number is 08 and the bit
switches select an address above that. Setting the bit switch in the on
position is considered a one by the processor.
