Control parameters Control parameters and setting values for determining the control func-
tions of a controller. Different parameters apply for each controller type.
NOTE
The control parameters are listed alphabetically.
Pulses max./min.
Significance Maximum no. of pulses
Explanation The Pulses max./min parameter only applies for pulse pumps.
This parameter is used to set the maximum number of pulses per mi-
nute in accordance with the employed pump.
Setting range The Pulses max./min parameter can be set at either 100 or 120 pulses.
Setpoint Specified value at which the control value (chlorine, pH, total chlorine,
conductivity) can be maintained by the controller. The setting range
corresponds to the respective measuring range.
Tn
Significance Integral action time (I-element)
Display Minutes (min)
Explanation On the basis of the integral action time Tn the dosing rate changes con-
stantly until the setpoint is reached. The higher the value of Tn, the lon-
ger it takes until the controller increases the dosing rate.
Tn higher: Control response becomes slower
Tn lower: Control response is faster
Setting range The parameter Tn can be varied from 0 ... 100 min (Tn = 0 means that
the "I-element" is deactivated, i.e. a pure P-control response applies).
It may not be possible to reach the setpoint value.
Tp
Significance Cycle period
Display Seconds (s)
Explanation The parameter Tp only applies for dosing pumps.
With the cycle period Tp a switching period is defined which must be
coordinated with the respective pump type.
Setting range The parameter Tp can be set from 10 ... 180 s.
Example Fast dosing pumps correspond to a low Tp, slow dosing pumps corre-
spond to a high Tp.
