14. If a menu is left without pressing ENTER, any change to that
menu item will NOT be stored. If no button is pressed for
3 minutes then the gauge will exit programming mode and
any changes which have not been stored will be ignored.
To access the Long User Code (LUC) menu (alarm point &
serial communications):
1. Press and hold ENTER until "SECUr COdE" appears (this
will take approximately 5 seconds).
2. Enter the 6 digit long user security code (it will be shown as
you enter it) and press ENTER. If the code is incorrect, the
gauge will exit programming mode.
3. ALARM SET MENU: If the code is correct then the alarm set
menu will be accessed, the display will show "A1Hi GAU 1"
followed by some volume amount and "n OPn" or "n CLS".
For dual displays, A1 and A2 are driven by the left volume,
and A3 and A4 are driven by the right volume. The display
shows the alarm number, the polarity, high or low set point,
and the alarm set point. Each alarm now has two points
for activating and deactivating the alarm, a high point and
low point. Each alarm can also be opened or closed if the
display goes into a "noL" or "bdL:xx" condition. This is
done in the "A1noL", "A2noL", "A3noL",or "A4noL" menu.
The alarm will be activated when the display goes above the
high set point but will not be deactivated until the display
goes below the low set point. For example, for alarm 1
high set at 535.4 barrels with the alarm contacts closed
(alarm active) when the product level is below the set point
(contacts open/alarm inactive at the set point and above),
the display would read "A1 Hi GAU 1" and "535.4 n CLS".
Another example, for alarm 3 low set at 45.2 barrels with
the alarm contacts open (alarm inactive) when the product
level is below the set point (contacts closed/alarm active at
the set point and above), the display would read "A3 LO
GAU 3" and "45.2 n OPn".
4. Press ↑ UP or ↓ DOWN to move the alarm set point up or
down. Each time the button is pressed the point is moved
by one inch. To get close to a point quickly, there are six
speed buttons: press 4 to increase by 10 inches, press 1
to decrease by 10 inches, press 5 to increase by 50 inches,
press 2 to decrease by 50 inches, press 0 to set the alarm
point to zero, or press 7 while in the low alarm menu to set
the low alarm equal the high alarm set point. To toggle
the polarity (alternate between closed and open) press the
decimal point button.
5. Press ENTER to store the new alarm setting, "StorE" will be
shown momentarily.
