Stream Sequencer Unit (SSU1)

The system is based on an 8-bit microcontroller. It is to be used for selecting one of the EIGHT streams by SYNC. The pulse from Analyzer if the trigger mode is Pulse. Stream selection will be according to preprogrammed timings if the trigger mode selected is TIME. With the help of a keypad and display on the front, the system allows to set and modify the following parameters of each stream.

Full scale value for Scaling analog input
Skip/Unskip a stream
Stream On Time
Power On status
Alarm set-points

In pulse mode, the system allows to skip/Inskip specified stream and in time mode if the value of Stream On time is programmed as zero, it is skipped. When the system is put in RUN mode, through the front keypad, the sequence is executed. The relay contacts are switched ON and OFF as per the predefined sequence. The Powered contacts will be used to switch the ON and OFF Solenoid Valves fitted in the system. Potential free contacts for each relay are provided for remote status indication. Alarm relays are also switched On and Off as per the input from the analyzer. Analog input is continuously sampled. The value of analog input is continuously displayed in RUN mode. When the PAGE key is pressed, Latched value for each stream is displayed for streams 1 to 6 respectively. Analog output for each stream is updated after its sampling & analysis are completed.
