Setup Channel screen allows to configure:
= General device settings: Int./Ext. Reference, Gas density, Engineering Units,
Full Scale Flow in L/Min and Relays assignment.
= Alarm Properties: Mode, High and Low settings in % F.S., Delay Time, Action.
= Totalizer Properties: Mode, Start Flow, Stop Volume, Action.
= Program Properties: Batch parameters and Timer Settings.
Press the Esc button under GENER. on the display in order to make General settings.
The following Internal/External/Program Reference display will appear.
e.2.6.1 Internal/External/Program Reference
The INT/EXT/PRG refers to point of origin for the valve control reference signal. To
change this, press the button UP, DOWN, ENTER respectively. In the internal reference
mode, the control signal is set by the user with the SDPROC controls (see section
e.2.4).
Pressing the ENTER button on the front panel under PRG on the display of the SDPROC
will toggle the reference between PROGRAM BATCH and PROGRAM TIMER. When
complete with settings, press the ESC button under EXIT on the display, to go to the
Density screen. The following Setup Gas Density Display will appear.
e.2.6.2 Setup Gas Density Display
The proper settings of the gas density (in grams per liter) are required for mass based
engineering units (LBPH, LBPM, GrPH, GrPM). Press the ENTER button under (--->)
on the display, to move the flashing cursor to the desired position. Pressing (+) or (-)
will increment or decrement the particular digit respectively. The numbers will change
from 0 to 9 and next to decimal point (.). Pressing (+) button one more time will change
highlighted position of the cursor back to 0. The same is true in backward direction
when pressing the (-) button. Only one decimal point is allowed. If changing position
of the decimal point is required, change decimal point to any desired digit, next move
cursor to the required position and adjust it to the decimal point with (+) or (-) button.
When complete with gas density settings, press the ESC button under NEXT on the dis-
play, to go to the Engineering Units screen. The following Setup Engineering Units
Display will appear.
