  • Page 8 A/B switch. Circuit Breaker Initiate Feature A built-in solid-state initiate device is used to operate the circuit breaker from the DigiTMR S2. Operational modes include Open, Close, Open-Close, Close-Open, and Open-Close-Open. Multiple operations such as Open-Close, Close-Open, and Open-Close-Open can be initiated using a programmable delay or by sensing the circuit breaker’s contact condition.
  • Page 9 Vanguard's Windows®- based Circuit Breaker Analyzer application is included with each DigiTMR S2. The software can be used to control the unit, review test records, and create circuit breaker test plans. Test records can be exported to PDF, Excel, and XML format. All future software updates can be downloaded from the Vanguard web site at no additional charge.

  • Page 10: Operational Modes

    1.2.2. Time-versus-Travel Circuit Breaker Analyzer Mode In Time-versus-Travel mode, the DigiTMR S2 applies a test voltage of 35 Vdc to each of the contact channels, thus allowing an analog to digital converter (A/D) to determine a close, open, or an insertion resistor as the state of the contact. The DigiTMR S2 records into memory 20,000 readings (in on second) from the A/D’s and the transducer position counters.
