A_20
L2 limit value can be set withing range of -60000 to +60000 digits, with respecting
decimal point settings.
Example: Water level measuring ( Scale 0,200 to 11,000m, L2 limit setpoint is 6.500m )
We set L2 limit value to
006
.
500
and confirm by key.
A_21
Limit L2 numeral hysteresis value (dL2)
can be set within range 0 to 30000 digits, with
respecting decimal point settings.
Due to Limit L2 control settings (A_23) relay acts as described on address A_16.
A_22
Limit L2 time hysteresis (dtL2) can be set in range 0.0 to 299.9 seconds.
When input signal rise over L2 + dL2 value or drop bellow L2 – dL2, device starts to count
down time hysteresis (dtL2) and then is relay opens/closes.
see more at address A_17
A_23
Limit L2 control settings defines relay behavior when limit L2 is reached
We can choose : direct/inverse level mode | direct / inverse window mode

A_24
Output signal type settings has two modes.
First mode (options 0,1 and 2) uses factory calibration where scale begin (A_02) is
assigned to begin of analog output signal and scale end (A_03) is assigned to end of
analog output signal
Second mode (options 3,4 and 5) offers possibility to assign user-defined scale to
analogue output signal (A_25 and a_26). Begin of analog output signal is assigned to A_25
value and end of analogue output signal is assigned to A_26.
A_25
User output signal scale start point can be set withing range of -60000 to +60000 digits,
with respecting decimal point settings. This value represents begining of analogue output
signal.
Example: Water level measuring ( Scale 0,200 to 11,000m,output signal 4-20mA is
assigned for range 5.000 to 10.500m )
We set user output signal scale start point value to
005
.
000
and confirm it by key.
Analogue output signal will be 4mA when measured value will be 5.000.
All settings on this address are valid only for options 3,4 a 5 set on address A_24.
A_26
User output signal scale start point can be set withing range of -60000 to +60000 digits,
with respecting decimal point settings. This value represents begining of analogue output
signal.
Example: Water level measuring ( Scale 0,200 to 11,000m,output signal 4-20mA is
assigned for range 5.000 to 10.500m )
We set user output signal scale start point value to
010 . 500
and confirm it by key.
Analogue output signal will be 20mA when measured value will be 10.500.
All settings on this address are valid only for options 3,4 a 5 set on address A_24.
A_44 L3 limit display in main display mode offers direct access to L3 limit value settings.
A_45
L3 limit value can be set withing range of -60000 to +60000 digits, with respecting
decimal point settings.
Example: Water level measuring ( Scale 0,200 to 11,000m, L3 limit setpoint is 7.500m )
We set L3 limit value to
007
.
500
and confirm by key.
A_46
Limit L3 numeral hysteresis value (dL3) can be set within range 0 to 30000 digits, with
respecting decimal point settings.
Due to Limit L3 control settings (A_48) relay acts as described on address A_16.
