Monitoring Manual Output Controls

The operation of manual trip and output override devices can be monitored and reported by connecting them as inputs to Genius blocks.

These inputs should be configured to use references at the end of the Discrete Input Table shown as ªreserved inputsº below.

%Q1024 or %Q12288

There is a one-to-one correspondence between Reserved Inputs and physical outputs.

The GMR software in each PLC automatically monitors the Reserved Inputs. On detection of either manual control, it disables the appropriate Genius diagnostics and the output autotest for the corresponding output circuit(s).

The application program must not command pulse testing on GMR outputs.
