8. MIN./MAX. MODE:
Conditions:
• Frontal panel switch set on "AUTO".
• Input "ON/OFF" set to ON.
• Switches S1.2 and S1.3 set to OFF.
Smin value setting:
Being switch S1.2 set to OFF and S1.3 in ON, to measure output motor voltage. Adjust Smin
potentiometer until to obtain voltage value desired (factory setting 110V). Finally, adjust
switch S1.3 in OFF position.
Operation:
To use two terminals commented on section 5 (Max. speed) to generate a MIN/MAX mode
depending of input digital signal (CPFL, SCO2-AR,...).
• Circuit open between two terminals => output voltage motor corresponds to minimum spe-
ed Smin (factory setting 110V).
• Circuit closed: output voltage motor corresponds to maximum speed Smax (factory setting 230V).
9. OTHER OUTPUTS
SELV 24V DC output:
Max. current = 100mA in permanently (200mA for 1 second peak every 30 seconds).
Can be used for powering a sensor using:
• 2 wires = current measurement signal 4-20 mA circulating on supply loop,
• 3/4 wires (output voltage 0-10V DC signal or current 0-20 mA signal).
In both cases, the sensor output should be connected to the regulator analogical input IN.
Relay output:
Free voltage contact normally closed if motor output > 0V.
Cutting capacity at 250Vac = 10A (Cos Fi=0.6) / 16A (Cos Fi=1).
10. GREEN INDICATOR LAMP ON FRONT PANEL:
Indicates that motor is running (clear when motor output is > 0V).
