2.5 Controls and displays
2.5.1 Panel
layout
Fig 1 shows the layout of the front panel. It contains the keyboard and liquid crystal display
(LCD). The keyboard is used to access the LCD and to:-
•
programme the flowmeter with site data, for example. path lengths, angles, heights
•
set up the inputs and outputs (including simulation for test purposes)
•
set up the relay functions and values on which to switch
•
display ultrasonic waveforms
•
display measurements and results
•
display diagnostic data
2.5.2 Screen organisation
The LCD screens are all numbered as listed in Appendix 1: LCD Screens.
The screens are arranged in levels, the lower levels being selected and accessed from the
one above.
When a lower level is displayed, it overlays the one above so that each is visible.
The ARROW keys move a highlighted area around each screen.
The ENTER key actions the highlighted instruction, for example to select a lower level screen.
The ESCAPE key reverts to the previous screen.
When the highlighted box requires data, the NUMBER keys are used.
The ENTER key stores that data in memory.
There are 4 FUNCTION keys at the bottom of the screen. Their function changes according to
what is displayed above them on the screen.
The display goes blank to save power 15 minutes after the last key stroke. Pushing any key
powers it up.
2.5.3 The status indicator
The status indicator operates as follows:
•
Continuous green – contentment
•
Continuous red – alarm condition exists or has occurred earlier and has not been
acknowledged. The meaning of this is defined by the user via screen S30: Fault Relay
Configuration, and details of the fault can be identified in screen S10: Fault Status (for
example, all faulty ultrasonic paths or depth paths).
•
Either light flashing evenly – running on battery.
•
Either light “blipping” on intermittently – running in power save intermittent mode.
•
No light at all – power off and battery run down.
With the alarm reset key the operator acknowledges the alarm and resets it.
The operation and setting up are described in Section 4: Installation, Appendix1: LCD
Screens and Appendix 2: GAFA Screens.
Note that the GAFA PC software provides similar facilities either locally via the front RS232
connector or the IR link, or remotely via a modem.
