Configuration

The IC697 CPU and I/O system is configured with

MS-DOS or Windows based programming software.

There are no DIP switches or jumpers used to config

ure the system. The CPU verifies the actual module

and rack configuration at power-up and periodically

during operation. The actual configuration must be

the same as the programmed configuration.  Devi

ations are reported to the CPU alarm processor func

tion for configured fault response.  Consult Reference

1 for a description of configuration functions.

Batteries

A lithium battery (IC697ACC701) is installed as shown

in Figure 2.  This battery maintains program and data

memory when power is removed and operates the

calendar clock.  Be sure to install the new battery be

fore removing the old battery.  If during power-up

diagnostics a low battery is detected the Module OK

LED (top) will not stay on.  Specific indication of a low

battery state is detailed in Reference 2.

Removing a Module

The following instructions should be followed when

removing a module from its slot in a rack.

Grasp the board firmly at the top and bottom of

the back of the cover.

Squeeze the rack clips on the back of the cover

with your fingers to disengage the clip from the

rack rail and pull the board firmly to remove it
