Notes on Module Operation
1. The machine operator monitors and modifies configurations in the microprocessor through
the 4 softkeys and the LID. Communication with the LID and the PSIO is accomplished
through the CCN bus. The communication between the PSIO, SMM, and both 8-input
modules is accomplished through the sensor bus, which is a 3-wire cable.
On sensor bus terminal strips, Terminal 1 of PSIO module is connected to Terminal 1 of
each of the other modules. Terminals 2 and 3 are connected in the same manner. See
, and
. If a Terminal 2 wire is connected
to Terminal 1, the system does not work.
2. If a green LED is solid on, check communication wiring. If a green LED is off, check the red
LED operation. If the red LED is normal, check the module address switches (
, and
). Proper addresses are:
