3. PAUSE MODE

When the PAUSEkey is pressedfrom the front panel, the microcontroller holdsthe process at the
current Stream with all outputs latched on their current status.
The PAUSE LED on the front panel will light up to indicate the instrument is in PAUSEmode.

4. MANUAL MODE

The Stream Selector instrument STL-96 can be operated manually by means of the front selection key.
The MANUAL MODE is available in both modes of operation, viz.: Timer andPulse Modes. When the
instrument is in MANUAL MODE, the Manual LED on the front panel will light up.
The desired stream has to be selected by user.
The OLED display will indicate as follows: -
The first line of the display shows which Stream Number is active and also the process status.
The second line of the display shows the time in seconds for which the selected Stream is active. This is
not active in Manual Mode.
The third line of the display shows process variable with respect to input signal to the instrument.
The fourth line of the display shows the mode of operation selected.
The following is the sequence in the MANUAL mode of operation:
1) Press STOP key if the instrument is in RUN mode.
2) Press INC key to select desiredStream number (1 to 6).
3) After selecting the desiredStream, press START key to start the process.
4) The corresponding Relay output will activate with potential free contacts.
The Low alarm and High alarm will function corresponding to the process input.
5) The 4-20mA DC output of the corresponding Stream will be active on the terminals.
The 4-20mA DC outputs of the other Streamsget latched to their last values.
6) Also, the Low alarm and High alarm of other Streams will get latched to their last status.
7) For next Stream, the same sequence from Point no. 1 will be applicable.
