PROGRAMMING GUIDE

When the level of liquid in the tank exceeds the reference value set from keypad, a negative error is produced (Error =
Reference – Feedback). Because the complemented output computing mode is selected and because the
complemented output is the speed reference, the higher the error absolute value, the higher the PID output value. This
means that the quicker the level increases, the quicker the pump suction. On the other hand, if the level is lower than
the reference, a positive error is produced, because the PID output is limited to 0%, the pump will not activate; if the PID
output is equal to the min. value for a timer longer than P255 = 1000*P244 = 5sec , the drive is put on stand-by.
