parameters must be set when differential level control is required. The parameter values must be set in the unit according to
P01
.
The GET LEVEL function can be used if the parameters affecting the transmitted value are valid. When using differential level control, a minimum
of 20 mm (0.8
″
) hysteresis must be set for the level between the Relay Energizing value and the Relay De-energizing value to avoid frequent
relay state changes.
