Figure 5–97: SINGLE-POLE AUTORECLOSE LOGIC (Sheet 1 of 3)
In runtime, AR mode can be changed through the mode control logic as shown in the following diagram. Initially, the autore-
closer runs in the mode as per AR MODE setting. Then the relay checks the AR activation inputs in each protection pass.
The AR mode is switched to the new mode when
• Only one of four activation inputs is high, and
• AP RIP operand is low, and
• The mode to be activated is different from the current AR mode
The logic allows activation of one mode at a time. Simultaneous multiple activations are ignored and mode switching does
not happen. However, a FlexLogic operand, AR MODE SWITCH FAIL, is asserted if either simultaneous multiple activa-
tions are initiated, or a single activation is initiated but recloser is already in progress.
