7 VSD Standardization
Motor standardization (speed acquisition) allows the LMV unit to control the motor rounds at the maximum frequency signal coming from the VSD. A
temporary standardization is factory set only for test purpose. The definite standardization must be performed on site by the Service Center (only if the
fan is supplied), before the plant test.
ATTENTION: To perform standardization, the burner must be in stand-by mode, not it lockout stage. The Safety loop must be
closed (X3-04).

Standardization process for
fan speed
By activating the standardization, without starting the burner up, the air actuator drives to ites maximum opening. Then the fan motor stars and the VSD
drives the motor to its maximum speed. The speed sensor, mounted on the motor, detects the rpm value. LMV stores the data and the motor stops.
ATTENTION: do not enter manually the rpm value of the motor data plate on parameter “StandardizedSp”.
ATTENTION: the power cable that connects VSD to motor must be screened.
