And the BASP led are on in both cpu's. Is a power supply problem? The 24 Volts and 15 Volts led is off and there is no voltage (24 and 15 Volts). The battery 3.6 V is dead too. thanks, Lucio

Hope you have a backup or Eprom with program, CPU might be cleared by now. Have a good look at the S135U manual, for more details about the (error)Leds. regards, Marcjan

Did you try to restart the CPUs with the coord. switch in test position? But most important: What do you read from the ISTACK? KaOst Edit: Did you check the manual -link above. In chapter 6 (from page 263) you might find some help.
