|
The TEC Model 1414 has been environmentally and seismically qualified by
type testing to IEEE Standards 323-1974 and 344-1975. The system is manufactured by TEC
under its Nuclear Quality Assurance Program in accordance with ANSI N45.2. The system is
qualified as documented in TEC Test Report No. 517-TR-03. The configuration for the Model 1414-7-(4) system (a typical three-channel system) consists of up to three monitoring channels per rack. Each channel consists of a field-mounted sensor and preamplifier. Signal processing electronics are located in the control room cabinet. A standard 19-inch rack-mountable system also is available. The field-mounted equipment consists of an Endevco 2273AM1 Accelerometer as the sensor, with a TEC Model 504A Charge Converter as the sensor preamplifier, serving each of the sensor sites in-line between the accelerometer and control room equipment. The signal is then rerouted to the control room signal processing equipment mounted in the Model 1414-7-(4) Rack. From the Model 504A, the signal travels directly to the Model 914-2 Valve Flow Monitoring Module. The Model 914-2 conditions and processes the signal, and displays and distributes any signal causing an alarm indication. The Model 133C Alarm Modules provide single-channel alarm functions. |
