Hello, We have a Trumatic 500 wit control Bosch cc220. We had the problem with storing graphic programs and the fault battery led indication on PS 100 was on. We changed the batteries for the EPROM module Bosch cp/ mem5 and unit NT1. When restarting the control unit doesn't open normally or respond to the keyboard and it gives the message " MEMORY CORRUPTED ADR# 000001 PUSH KEY TO RESTART". The message comes back the same after pressing restart. Is there anyone who can advise the problem and solution. Thanks, Jamal
If you haven't solved the problem yet. The red LED on the PS100 indicates a 24Vdc error from the incoming supply. The control will still work. Please take picture of screen will booting and forward it to me, behr@icon.co.za Harald
