Differential
The “DIFFERENTIAL” or dead band setting allows for a hysteresis to
be programmed in to the conductivity trip point. A programmed hyster-
esis value prevents the bleed relay and solenoid from cycling on and off
repeatedly when the conductivity reading hovers around the trip set
point. The value entered in the “DIFFERENTIAL” is the amount of
conductivity, away from the trip “SET POINT”, that the bleed relay will
shut off.
Press “ENTER” from this screen to change the value. The value will
have a flashing cursor indicating that it can be changed. Press the “UP”
or “DOWN” key to increase or decrease the value. Press “ENTER” to
save the “DIFFERENTIAL” value.
