Instructions for adjusting the motor rotation speed
The inverter allows the adjusting of three rotation speeds for the
motor-fan to be carries out:
Vs level (factory setting: 30 Hz): rotation speed in relation to the
burner ignition stage
V1 level (factory setting: 25 Hz): rotation speed in relation to the
first stage of operation
V2 level (factory setting: 50 Hz): rotation speed in relation to the
second stage of operation.
V3 level: to be ignored.
It is not possible to adjust V2 to a lower value than V1 and Vs.
To adjust the output signal frequency in relation to the 3 speed levels
it is necessary to enter programming mode by holding down the SET
key for a few seconds until the LEDS start flashing.
Having entered programming mode, the LEDS related to Vs AND
V3 will begin to flash simultaneously; the meaning of this function
is explained in section "STORING OF THE WORKING INTERVAL
OF AIR SERVOMOTOR". Press the SET key for about 2 seconds
until the green LED related to Vs begins to flash; it is now possible
to adjust the motor rotation speed value in Vs by pressing the +
key to increase the speed value or the - key to reduce it, as many
times as necessary.
Every pressure on the + or - keys corresponds to an increase
or decrease of 0.2 Hz of the inverter output signal frequence. To
quickly change the frequency, hold one of the two buttons down for
a prolonged period (maximum 16 seconds).
The motor follows the adjustment by increasing or decreasing
rotation speed in relation to the frequency set.
The frequency value is displayed approximately by the number
of flashing red LEDS. With each increase of 4 Hz in the output
frequency signal an additional LED will light up (see table 1).
The table 1 represents the intervals in which the set frequency
(INVERTER) can be found, in relation to the number of lit red LEDS.
Having finished the speed adjustment in Vs, press the SET key for
about 2 seconds to bring the current speed level to V1: the green
LED related to V1 begins to flash, as in the figure.
At this point the same procedure described above is repeated to
adjust in sequence the motor rotation speed in V1 and V2, while
V3 is ignored.
