The "border" between static and electromechanic steps is defined with a dedicated
−
parameter in the static setup menu.
The power of a standard electromechanic step must be equal to or higher than the
−
biggest static step.
The setting of the step power is carried out as usual, setting in P.02 the kvar of the
smallest step and in P.06... the coefficients of the various steps, both static and standard.

Starting from this position, press at the same time the keys +, - and SCROLL for 5
seconds, until the display will show St.S indicating the access to Static setup menu.
Press the MANU/AUTO key to enter the subsequent parameter.
Press the MODE key to return to the previous parameter.
Press the + and - keys to view and change the setting of the selected parameter.
The setup exit is automatic once the last parameter is exceeded.

After having closed one step output, the measure acquisition is suspended for the
time specified by this parameter, in order to allow the external static contactor to
connect the capacitors. This function allows to avoid regulation oscillations. Set this
value according to the technical characteristics (closing time) declared by the
manufacturer of the static contactor.
Same as previous note, referred to disconnection.
Number of static steps. If set to ALL, all of the 11 outputs are treated as static steps.
Otherwise, setting for instance 6, steps from 1 to 6 are considered static, while step
from 7 to 11 are considered electromechanic.
Minimum time between two switching of the electromechanic steps.
2.6 DIAGNOSTIC READINGS
To estimate the behaviour of the regulation, it is possible to access two diagnostic
readings that indicate the average distance from the setpoint in the last 5 seconds. This
indication helps to find the parameter setting that gives the best results on a certain plant.
