2
Double Start
Run command is set when both Start 1 and Start 2 sig-
nals are high. It is reset when both the start signals are
low.
This can be used for a simple tank level control with hys-
teresis: if the tank has to be filled, two NC contact sen-
sors will be placed at minimum and maximum levels.
The drive will start below the minimum and stop above
the maximum.
If the tank has to be emptied, two NO contact sensors
have to be used. The drive will start above the maximum
and stop below the minimum.
3
Start sign 1 + Analogue
Run command is set when Start 1 signal is high and a
selectable analogue input is below (or above) a program-
mable threshold.
This can be used for a tank level control, where the ana-
logue measurement is used for both starting the pump
and controlling the speed.
4
Solar only
Run command is always active. Actual running condition
is determined by DC voltage level available from the solar
array.
