CE MARKINGWhen using ASTAT Plus in the EU, compliance with EMC is Plus range comply with the generic EN 50081-2 and EN 50082-2 ASTAT Plus. Soft power before installing or voltages are present in the motor circuit even when the starter is OFF. Anisolation contactor is recommended, configured to provide automatic isolation when themotor is turned may contain more than one live circuit .

Comparison of starting systemsThere are numerous applications where soft starting and limitedcurrent peak are needed and thereby making direct starting ofsquirrel-cage motors impossible. Traditionally in such cases othertypes of starting with reduced stator voltage have been resorted to. Thebest-known are star-delta starters, autotransformer starters, statorresistance starters or using part winding reduced starting voltage imposes a current limitation, and as aconsequence the starting torque is also reduced, but there will alwaysbe peaks during the change from one point or state to another whichcan damage the machine being driven.

9 In order to analyse theperformances offered by each of these different types of starters, thefollowing table shows the special characteristics of each of them,comparing with the ASTAT that in general all reduced voltage starts produce a reduction intorque in squared proportion to the current in the phases of the motor(not on the line) and the latter in turn is reduced in linear proportion tothe voltage. From this it can be deduced that any start with reducedvoltage reduces the torque in squared proportion to the voltage permotor phase. From this point of view soft starting produces, just like anyother reduced voltage start, a reduction in starting torque, according% of direct start100%30 - 40 or 64%58 - 70%65%33%Depending on adjust,current (in the line)max.

The advantage, of course, is the ease withwhich this ramp can be controlled to produce a soft start in accordancewith the actual requirement of the the comparison table it can be seen that the maximum startingtorque attainable using the soft system is 90% of that which directstarting tends to.
