Operation, Protection, and Module Status

Operation of this module can be controlled by the

three-position RUN/STOP switch or remotely by an

attached programmer and programming software.

Program and configuration data can be locked

through software passwords or manually by the

memory protect keyswitch.  When the key is in the

protected position, program and configuration data can

only be changed by a programmer connected parallel

only (to the Bus Transmitter module).  The status of a

CPU is indicated by the seven green LEDs on the

front of the module.

Operating Temperature

The CPX 928 requires forced air cooling for proper

operation in ambient temperatures greater than 50C

(122 F).  A fan capable of 70 CFM (including filters)

should be located beneath slot 1 of the rack containing

the CPU.

Fan assemblies (IC697ACC 721. IC697ACC724. and

IC697ACC744) can be ordered for direct mounting on

the IC697 rack.  Refer to the applicable Programmable

Controller Installation Manual for detailed information.
