SETUP 2.1 determines the measurement unit for the displayed
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 unit will have consequences for operator and
SETUP-level values.
Please note that the span (SETUP 2.3) has to be adapted as well; the
calculation is not done automatically.
This setting determines for height and its span the number of digits
following the decimal point. The following can be selected:
00000 - 1111.1 - 222.22
With the span, the sensor signal is converted to a height. The span 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 4245.8 cm.
The selected unit is cm with no decimals.
The span is 4245.8. Enter for SETUP 2.1: "cm", SETUP 2.2: "1111.1",
SETUP 2.3 "42458" and SETUP 2.4 "00000".
Enter here the "not measured" quantity which is present without a
sensor signal being generated.
Also, a negative offset can be entered: do press the middle and right
button simultaneously.
When the level signal is zero, then it is possible to ignore or disable
the low level alarm. The following settings can be selected:
DEFAULT: in case of a low level alarm and no signal, it will
switch the alarm output and indicate the alarm on the
display.
NO RELAY: in case of a low level alarm and no signal, it won't
switch the alarm output but will indicate the alarm on
the display only.
IGNORE: in case of a low level alarm and no signal, it won't
switch 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 level is lower than this value. With value 0.0 this function
is disabled.
The high alarm is set with this setting. An alarm will be generated as
long as the level is higher than this value. With value 0.0 this function
is disabled.
An alarm generated by SETUP 3.2 "low" can be ignored during X-time
period. If the actual level is still incorrect after this delay time, then an
alarm will be generated.
An alarm generated by SETUP 3.3 "high" can be ignored during X-
time period. If the actual level is still incorrect after this delay time,
then an alarm will be generated.
One transistor output is available to transmit the alarm condition.
Assign with this function the type of alarm to be transmitted:
low level alarm, high level alarm, both alarms, or none.
