Parameterization

Notes on setting:
When setting the control values the display shows:
l
the selected parameter
in the message line
l
the control value (conductivity, temperature, hysteresis) and
the delay time DL before a relay closes or opens
in the upper 7 segment display.
l
the relay number
in the lower 7 segment display.
Setting:
Submenu: "PARA UL/LL".
With
enter submenu
"PARA UL/LL".
With
select PARA UL LF
With
enter selected submenu: Setting of
upper limit value UL LF (relay 1).
<- Relay number (e.g. 1) is displayed.
With
set the flashing figure
(setting range 0-9).
With
accept and go on to next figure.
Here the maximum setting range is the
configured recorder range Rec 1.
After the last figure go on to HYST OG LF.
With
set the flashing figure and enter
with
.
Setting range is 0 ... ±10 % of recorder
range.
After the last figure accept with
and go on
to "DL UL LF".
The set hysteresis works symmetrically with positive and negative deviation around the set control
value.
Example:
With an upper control value UL of 2.85 mS/cm and a hysteresis of 0.15 mS/cm
the relay switches when the measured value exceeds 3.00 mS/cm and switches back
when the measured value goes below 2.7 mS/cm.
