Page 59: Running Ct-6500 In Tandem
For timing application requiring more than 12 timing contact channels, the user can use two or more CT-6500s to time a circuit breaker. A typical application is to use a CT-6500-12 and a CT- 6500-6 to time a 18-contact ATB. To time this circuit breaker, the user can use the following steps: n Connect the CT-6500-12 to phase A and B of the circuit breaker. -
Page 60: Ct-6500 Trouble Shooting Guide
Make sure the contact close state is longer than 10 ms. The CT-6500 has a 10ms de-bounce time, any contact state less than or equal to 10ms is invalid, thus the delay time is probably too slow. - Page 61 9. How does one review the current analysis setting? n Select Analysis (Press key #1). n Select PRINT SETTING (Press key #3).
