EPROM Technology and Data Retention

The module uses UV-erasable EPROM technology for permanent program storage. A quartz window on top exposes the memory chips for erasure. You can erase the contents with 15 minutes of strong UV light exposure. The ABB 07 PS 61 R1 retains all data for over a decade without power. Consequently, you never need a backup battery for this memory module. The plastic housing protects the quartz window from accidental light exposure. A protective label covers the window during normal operation.

Compatibility and System Integration

You insert this memory module into any Procontic CPU or memory expansion slot. The 64-pin edge connector matches the standard Procontic memory interface perfectly. The CPU automatically loads program data from this module at power-up. You can also use the module as a permanent program backup device. The ABB 07 PS 61 R1 works with Procontic 07ZE and 07ZB central units. It cannot write data during normal CNC operation. Therefore, you need a separate EPROM programmer to burn new memory chips.

Installation and Handling Guidelines

You must ground yourself before handling this EPROM memory module. Static discharge will destroy the sensitive memory cells instantly. The quartz window requires protection from direct sunlight and fluorescent light. Ordinary room lighting will not affect the stored data significantly. You should cover the window with the provided label after programming. The module draws no power from the Procontic backplane during operation. It only supplies stored program data when the CPU requests it. The operating temperature ranges from 0°C to 55°C.
