In some situations, an error code is only the result of another error and not the actual cause of the problem (for example, a fault in the protection detection circuitry can also lead to a protection). Error Codes In case of non-intermittent faults, write down the errors present in the error buffer and clear the error buffer before you begin the repair.

Alignments 8. EN 77 How to Calculate the Value of an Option Byte • Calculate an Option Byte value (OP1 .. OP7) in the following way: • Check the status of the single option bits (OB): are they enabled (1) or disabled (0). • When an option bit is enabled (1) it represents a certain value (see column “Bit value” in the table below). When an option bit is disabled, its value is 0. • The total value of an Option Byte (decimal) is formed by the sum of its eight option bits.
