Description

System controller model SC-770 is a general purpose controller which is used in the master pillar of most TSA portal monitors.

A four line, sixteen character LCD display is used to monitor system status and setup information. Setup is accomplished using the twelve key keypad on the front of the unit. All of the settings and system status are stored in flash memory internal to the unit. The status information can be downloaded using the TSA software.

OPERATION: The SC-770 is programmed with default values before being shipped from the factory. Final setup is necessarily site specific, and should be optimized to meet local requirements.

The unit has a base time interval of 200ms. All internal timing is based on this interval. The number of base intervals used in the moving average may be programmed. The alarm comparisons are performed every 200ms when the system is occupied.

The system also logs system activity to flash memory. Each entry is time and date stamped. Events that are logged to flash memory include: hourly background updates, tamper alarms, background faults and radiation alarms. The flash memory may be downloaded to a PC via the RS-232 port.

The SC-770 controls the discriminator settings via a serial link. The SCA-775 outputs are sent to the SC-770 as differential signals to minimize interference and crosstalk.

Applications

System controller model SC-770 and single channel analyzer model SCA-775 are designed as essential components located in the pillars of TSA’s portal monitors.
