Note
Set switches 1–3 as shown to select a
14-24 Bar setpoint range with a 4 Bar
proportional band.
Adjust the setpoint potentiometer to
20 Bar (which is 60% rotation from
the "-" or CCW end of the setpoint
potentiometer).
Adjust the minimum speed potentiometer
completely CCW (to set the minimum
speed to 20% of 230 V or 46 V).
Setting switch 4 to ON causes the
motor to always run at minimum speed
or greater.
Note 1
If min speed is set to 40%, then output
turns off at 230 V*0,4 = 92 VAC when
input voltage drops to 6,0 V* 0,4 = 2,4 Vdc
