Table 20 Default Relay Output Status Indication

Note: Although the Input and Output states are pre-defined, the system configuration utility allows the

user to individually associate Indicator states to both Input and Output states. This allows the

user to create custom indication schemes for their application. This can be achieved by

implementing the procedure for configuring the SYSTEM.INI file detailed in PD-8082B.
