EXPLANATION OF SETUP MENU 2 – HEIGHT

If desired the height of the level column can be calculated and displayed.
Note: The linearization influences the operator values for level and percentage and not the height.

EXPLANATION OF SETUP MENU 3 – ALARM

With these settings, it is determined how the level will be monitored and the functionality of the
transistor / relay outputs be determined.
Please be aware that the alarm levels can be programmed at operator level as well. Moreover, the
function can be locked or hidden (setup 4.1).

SETUP – 2.1 determines the measurement unit for height:.
The following units can be selected:
mm - cm - m - mtr - inch - ft - mmwk - mmwc - cmwk - cmwc
mwk - mwc - inwc - ftwc - mbar - bar - psi - no unit.
Alteration of the measurement unit will have consequences for operator
and SETUP-level values.
Please note that the Span (2.3) has to be adapted as well; the calculation
is not done automatically.
This setting determines for height the number of digits following the
decimal point. The following can be selected:
00000 - 1111.1 - 2222.22
With the span, the sensor signal is converted to a height.
The span for height is determined on the basis of the selected
measurement unit at 20mA.
The more accurate the span, the more accurate the functioning of the
system will be :
Example Calculating the span for height > next page
Let us assume that the sensor generates 20mA at a level
of 2,481.3 cm, the selected unit is "cm".
The span is 2481.3
Enter for SETUP – 2.3: "2481.30".
This setting determines the number of decimals for Span (SETUP 2.3).
The following can be selected:
0 - 1 - 2 - 3 - 4 - 5 - 6
Enter here the "not measured" height which is below the sensor, in case a
pressure transducer is used for example to measure the level.
Also, a negative offset can be entered: do press the middle and right
button simultaneously.
The alarm function can be set to monitor either level, height or percentage
(of the sensor input signal).
The behavior of the monitoring function for low and low-low alarm values
can be adjusted for those cases where the sensor input signal is at its
lowest value (4mA, 0% or below its cut-off point), for example when the
tank is empty.
The following can be selected:
DEFAULT: Normal behavior: a low / low-low alarm condition switches
on the alarm output(s) and the display will indicate the
alarm status.
NO RELAY: A low / low-low alarm condition will NOT switch on the
alarm output(s), the alarm status is indicated on the display.
IGNORE: A low / low-low alarm condition is completely ignored: no
output will be switched and no indication on the display.
The low-low alarm is set with this setting. An alarm will be generated as
long as the value lower as this value.
The low alarm is set with this setting. An alarm will be generated as long
as the value is lower as this value.
