Notes on Module Operation
1. The machine operato r mo nit ors and modifies conf ig urations in the microp r oc es s o r through
the 4 softkeys and the LID . Communication wit h th e LID and the PSIO is accompl ished
through the CCN bus. The communication between the PSIO, SMM, and both 8-input
modules is ac complished throug h the sensor b us, which is a 3-wire cable.
On sensor bus termina l s tri ps, Terminal 1 of PSIO modu le is connected to Termin al 1 of
each of the other modules . Terminals 2 and 3 are conn ec t ed in the same manner. See
Figure 49, Figure 50 , Figure 51, Figure 52, and Fi gure 53. If a Term inal 2 wire is conn ected
to Terminal 1, the system does not work.
2. If a green LED is solid on, check commu nic a tion wiring. If a green LED is off, che c k the red
LED operation. If the r ed LE D is normal, check the mo dul e address switches (Figu re 49,
Figure 50, Figure 51, Figure 52, and Figure 53). Proper addresses are:
