7.4 Cleaning parameters

The following parameter relates to the cleaning function.

Note: A full menu structure is shown in section 11.

7.4.1Start On - P260

Use this parameter to select how the cleaning cycle starts. The selectable options are:

AutoClean

Manual 5s

Off

The default is “AutoClean”.

7.4.2Interval - 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

7.4.3Cleaning 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.

7.5.1Lower 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

7.5.2Upper Range Val - P401

This is the sludge blanket level in metres (or feet if Imperial version) for the maximum mA output. This value is by default set to "Auto".

Parameter values (Metric)			Parameter values		(Imperial)
Default	Min	Max	Default	Min	Max
Auto	0.000m	7.000m	Auto	0.00 ft	23.00 ft

Note: In the case of the default setting the upper limit is defined as being at the programmed transducer blanking distance P623 from the front of the transducer face.
