2 - HEIGHT

21 determines the measurement unit for height.
SETUP
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 (
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
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 100% signal.
The more accurate the span, the more accurate the functioning of the
system will be :
Example Calculating the span for height
Let us assume that the sensor generates 100% signal at
a level of 2,481.3 cm, the selected unit is "cm".
The span is 2481.3
Enter 2481.3 for
Enter here the "not measured" height which is below the sensor.
Also, a negative offset can be entered: to do so press the middle and right
button simultaneously.

3 - ALARM

When the level is zero (or the offset value
ignore or disable the level monitoring. The following settings can be
selected:
in case of a low-level alarm and zero level, it will switch
DEFAULT:
the alarm output and indicate the alarm on the display.
in case of a low-level alarm and zero level, it won't switch
NO RELAY:
the alarm output but will indicate the alarm on the display
only.
in case of a low-level alarm and zero level, it won't switch
IGNORE:
the alarm output and nothing will be indicated on the
display.
The low alarm is set with this setting. An alarm will be generated as long
as the actual level is below this value. Entering 0.0 disables this function.
The high alarm is set with this setting. An alarm will be generated as long
as the actual level is above this value. Entering 0.0 disables this function.
An alarm generated by

period. If the actual level is still incorrect after this delay time, then an
alarm will be generated.

A transistor output is available to transmit alarm conditions. Assign with
this function the type of alarm to be transmitted:
