There are three washing modes available accessible via the PLC unit.
Allows the washing head assembly to descend to a desired depth and then pause. The AutoBoss unit then walks to the next stop point and the washing head assembly is lifted to the surface. There is then another pause and walk before the washing head descends again to the desired depth. This mode allows for a rapid, light single pass wash of the net. At this setting at least 1,500m2 of net will be washed in 1 hour.
Allows for a more focused “right-sized” washing operation. The washing head will descend to the set depth, pause, and then lift back to the surface, pause, then drop to a second pre-set depth, pause, and then the AutoBoss will walk to the next washing point. The washing head will then be lifted to the surface, pause, then drop to the first depth set point, pause, then lift to the surface. Then AutoBoss will pause and move again to the next washing point and the cycle will repeat. This mode will focus washing in the areas where net is more fouled – at the surface – and run the washing head over this area 3 times while the deeper part of the net just gets one pass.
Allows for a much deeper clean and will enable the washing head to only walk at the surface if that is required/desired. In Mode 3 the AutoBoss will only walk at the surface (mode 1 and 2 alternate between walking when the washing head is at the surface and when the washing head is at depth).
Three washing depths are set—a shallowest point, a mid-point and a deep point. These can be set at anything from zero to the maximum depth of the winch rope.
In mode 3 the washing head will drop to the first set depth, pause, then lift back to the surface. It will then drop to the second set depth, pause, and lift back to the surface. It will then drop to the third set depth, pause, and lift to the surface. Once these three drop/lift cycles have been completed in one location the AutoBoss will walk to the next set point and repeat the cycle.
This results in the strip of net being covered up to 6 times by the washing head assembly. This can be useful in situations of heavy fouling. By changing the depth set points shallower parts of the net can be covered more often than deeper parts of the net.
