Manual low speed
(A2-A3)
Defrosting. Will give adjusted min. speed if run (5-6) is
closed.
Input signals
(1-3)
Adjusted to central control.
(0-5V, 0-10V, 1-5V, 2-10V, 5-10V, 10-0V, 10-2V, 10-5V,
0-20 V Phase cut, 0-20mA, 4-20mA).
See adjusting DIP-switches, page 4.
Frequency
measurement
(3-4)
0-10VDC relates to 0-100Hz. Dvs 0,5V = 5Hz, 5V = 50Hz.
The speed of the rotor is proportional to the frequency.
Run
(5-6)
Must be closed if external start is not being used.
Thermal contact
(7-8)
Must be closed if the thermal contact in the motor is not
being used.
