Use this parameter to select how the cleaning cycle starts.
The selectable options are:
x AutoClean
x Manual 5s
x Off
The default is “AutoClean”.
7.4.2 Interval - P264
Use this parameter to programme the interval between cleaning cycles (see also P444 - cleaning duration).
This parameter is programmed in hours and minutes.
Default Min Max
1:00 0:10 1:39
7.4.3 Cleaning Time - P444
The duration of the cleaning cycle can be programmed in seconds
Default Min Max
0:10 0:10 0:20
7.5 mA output parameters
The following parameters are used to program the mA current output.
7.5.1 Lower Range Val - P400
This is the sludge blanket level in metres (or feet if Imperial version) for the minimum mA output, either 0 or 4mA
as programmed using P403.
Parameter values (Metric) Parameter values (Imperial)
Default Min Max Default Min Max
0.000m 0.000m 7.000m 0.00 ft 0.00 ft 23.00 ft
