What does the diagnosis LED ON mean on TeSys Giga contactors ? How many on/off operations left after the LED is ON ?

The diagnostic LED shall be ON,
  1. when the contactor (switching module) reaches its end of life, means it have reached 85% of its electrical life. The electrical life depends on the operational voltage and current, utilisation category, make break current (AC3/AC3e) and depends on application type. So, the remaining number of operations shall also vary depending on multiple factors : 1 beat
  2. Coil undervoltage (A1-A2 <0.8Uc): 2 beats
  3. Coil overvoltage (A1-A2 )1.1Uc): 3 beats
  4. Internal fault: continuous beats
  5. Remote wear diagnosis (RWD) module (only when Advanced version) cannot enable remote alarm for central monitoring: 4 beats
