Product Precautions
GE IC697MEM715 is a 128 KB CMOS expansion-memory daughter board for supported Series 90-70 CPU and programmable coprocessor modules. It expands program and data storage without occupying an additional rack slot.
- Adds 128 KB of battery-backed CMOS memory
- Mounts as a daughter board without consuming another rack slot
- Supports documented Series 90-70 CPU and PCM modules
- Can be configured for program and data storage
Install IC697MEM715 on the documented base module only after rack power is removed and the retained program is backed up. Verify CPU or PCM compatibility, memory configuration and battery-backed retention before returning the controller to service.
Important Notice: Verify IC697MEM715 from the physical marking and current manufacturer documentation before installation or configuration.
Apter Power IC697MEM715 Manuals and Guides
Apter Power IC697MEM715 Product Technical ReferenceApter Power IC697MEM715 Installation and Verification GuideImportant Notice: Use these model-specific records together with the current manufacturer publication and the installed-system documentation.
Series 90-70 program expansion
Adds retained memory to a compatible CPU when the installed application exceeds base memory.
PCM application storage
Expands supported programmable coprocessor memory for documented logic or data duties.
Legacy controller maintenance
Restores the exact 128 KB daughter-board configuration in an installed Series 90-70 system.
Controlled memory migration
Supports a documented backup, replacement and restore process without adding another chassis slot.
Read the applicable GE instructions before work. Verify IC697MEM715 and the installed system configuration.
1
Confirm the complete IC697MEM715 marking and the supported base-module part number before work.
2
Back up the retained program and configuration before removing rack power.
3
Remove all rack power before installing or removing the daughter board.
4
Use ESD controls and avoid contact with CMOS components and connector fingers.
5
Verify the base-module battery condition before relying on retained memory.
6
Seat IC697MEM715 evenly on the documented connectors without bending pins.
7
Confirm configured program and data memory allocation after installation.
8
Restore the approved application and complete a controlled controller functional test.
Technical notes
Install IC697MEM715 on the documented base module only after rack power is removed and the retained program is backed up. Verify CPU or PCM compatibility, memory configuration and battery-backed retention before returning the controller to service.
