Follow the procedure below to improve the situation.
Enter the service code (552621) and change the following parameters.
P43 = Breakpoint. Change to a value that will enable you to apply gain to the
real echo whilst avoiding applying gain to a false echo (e.g. pump heads).
P44 = Slope. Change to a value that will enable the true echo to be
distinguishable from any other echoes.
Note: Care should be taken when employing the above two parameters, too much
gain may cause the unit to go to a multiple if the level in the well goes high. Also,
the gain is only a software multiplier it does not increase the raw signal strength.
If the echo is disappearing the transducer needs to be moved to a better position
or upgraded.
P47 = Outside Count. Change to 25. This is the parameter that controls the
movement of the gate. Increasing the value makes the movement of the gate to
another echo that is closer to the transducer less likely.
P82 = Far Loss. Change to 1. This enables smaller echoes to be ‘seen’ at the end
of the units programmed empty distance.
P84 = Mid Loss. Change to 10. See above.
P870 = Fill Damping . Set the value to just above the max rate of filling. If the
unit does decide to go to a closer echo it will do so at the damping rate thus
giving the unit time to recover the true echo before the unit shows a large reading
change.
P871 = Empty Damping . Set the value to just above the max rate of emptying.
If the unit does decide to go to a multiple it will do so at the damping rate thus
giving the unit time to recover the true echo before the unit shows a large reading
change.
