Page 28: Operation
Operation Understanding Trip-Free Operation The stored-energy mechanism has an instantaneous trip-free capability. If the Series 2000 Circuit-Switcher is closed into a fault sensed by the user-furnished relaying, the mechanism will immediately trip. To accomplish trip- free operation, the stored-energy mechanism uses two spring assemblies: one for closing and one for opening. -
Page 29: Manual Operation
Operation Manual Operation To trip the interrupters: Push the manual TRIP lever counterclockwise as indicated by the TRIP lever label. See Figure 24 on page 23. The opening latch in the stored-energy mechanism will release, discharging the opening spring. This action trips the interrupters and forces the opening and closing pistons in the mechanism downward, as shown by movement of the indicator to the Discharged window. -
Page 30: Understanding The Optional Remote Gas-Density Monitor
Operation Understanding the Optional Remote Gas-Density Monitor The remote gas-density monitor provides local and remote indication of the gas density in each interrupter in terms of percent full. The system can be wired to provide remote indication of the gas density of each interrupter via three analog 0- to 1.0-mA dc outputs.
