7.3 De-sludge parameters

The following parameters relate to the de-sludge function and are found in the setup menu.

Note that minimum and maximum parameters relating to time are 00:00 and 23:59 respectively. Minimum and maximum parameters relating to sludge level are 0.000 to 7.000m (0.00 to 23.00 feet)

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

7.3.1Start On - P250

Use this parameter to select how the de-sludge cycle starts. The selectable options are:

￿None

￿Time

￿Sludge Level

The parameter defaults to “None” which means it is not used.

Parameter values:

Default Min Max

7.3.2Stop On - P251

Use this parameter to select how the de-sludge cycle stops. The selectable options are:

￿None

￿Time

￿Sludge Level

The parameter defaults to "None" which means it is not used.
