The following settings apply to the signal device:
Redox controller
parameters page 1
(signal device)
The set point (W) function is used to set the nominal value within the measuring range.
Value range: 0 mV to 1000 mV
The switch difference (XSD) function is used to specify the switch hysteresis around
the set point. The stated percentage refers to the nominal value.
Value range: 0.0 % to 30.0 %
The starting time of the corresponding relay can be delayed by the time specified with
the switch delay time on function.
Value range: 0 sec to 240 sec
The switch-off time of the corresponding relay can be delayed by the time specified
with the switch delay time off function.
Value range: 0 sec to 240 sec
The set point difference (LW) function can be used to enter the absolute interval
between switching point 2 and the set point.
Value range: 0 mV to ± 1000 mV
The switch difference (X2SD) function can be used to specify a switch hysteresis
around switching point 2. The stated percentage refers to the absolute value of
switching point 2.
Value range: 0.0 % to 30.0 %
Through selecting the module selection function one returns to configuration module
selection.
Page 2 displays additional parameters on a second page of settings.
The following settings apply to the 2-point PID controller:
Redox controller
parameters page 1
(2-point-PID)
The set point (W) function is used to specify the nominal value within the measuring
range.
Value range: 0 mV to 1000 mV
The proportional area (XP1) function is used to specify the proportionality factor for the
P-proportion of the controller.
Value range: 0 % to 999 %
