5-282 C60 BREAKER PROTECTION SYSTEM – INSTRUCTION MANUALCONTROL ELEMENTS CHAPTER 5: SETTINGS5Figure 5-150: 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, theautorecloser runs in the mode as per AR MODE setting. Then the relay checks the AR activation inputs in each protectionpass. 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 modeThe logic allows activation of one mode at a time. Simultaneous multiple activations are ignored and mode switching doesnot happen. However, a FlexLogic operand, AR MODE SWITCH FAIL, is asserted if either simultaneous multiple activations areinitiated, or a single activation is initiated but recloser is already in progress.
