Друкувати сторінкуThe ASHE Stream Selector Model STL-96is a microcontroller based Instrument for the accurate process
control of a multi-stream system in Analytical applications. The STL-96Stream Selector has a 20
character by 4 line back-lit OLED display which showsthe process status and various setting parameters
for application specific timing and control of the six Streams. The STL-96 instrument provides a total of
18 nos. of potential freerelay contacts with LED indications on the front panel.
Besides the above, the instrument provides six nos. of 4 to 20mA retransmission analog outputs
corresponding to each stream.The instrument providesSample and Hold feature for these 4 to 20mA
retransmission outputs.
The STL-96Stream Selector offers two modes of operation, namely the AUTO and MANUAL modes. The
operational logic is as under:
In the Manual mode, the operator can select a particular Stream number.
In the Auto mode, there are two sub-modes of operation, viz., the Timer mode and Pulse
mode.
In the Timer mode, the selected Stream Number is active for the set time.
In the Pulse mode, the number of Streams selected based on the Pulse input.
1. RUN MODE
After Power Supply is switched on, in the RUN mode of operation, the Stream Selector will execute the
desired sequence of the Streams. The selected Stream output relay gets energized and the
corresponding Low Alarm, High Alarm and 4 to 20mAAnalogOutputgets activated. The RUN LED on the
front panel will light up to indicate the instrument is in RUN mode.
The status of outputs is as follows: -
2. STOP MODE
When the Operator presses theSTOP key from the front panel, the microcontroller stopsthe process at
the current stream and deactivatesthe selected relay output with latched 4-20mA Output.The STOP
LED on the front panel will light up to indicate the instrument is in STOP mode.
