8.3. Operating Sequences
The given times are: operating transfer time, product opening time and contact transfer time. The
denitionsofthesetimesaregivenbelow:
1. Operating transfer time (OTT) – IEC 60947-6-1 §3.2.6
Thistimeismeasuredfromtheinstantthemonitoredsupplydeviates(notconsideredasavailableanymore)totheclosingof
maincontactsonanavailablealternativesupplysource,exclusiveofanypurposelyintroducedtimedelay.Inotherwords,this
istheglobaltransfertime,excludingallprogrammabledelays(timersconguredto0).
Ifthesupplydeviationisnotmonitoredbytheproductitself,butbyanexternalcontroller,OTTtimestartswhentheorderis
received by the product.
2. Product opening time I-0 or II-0 (POT)
This time is measured from the instant that the monitored supply is not considered as available to the opening of the main
contacts,exclusiveofanypurposelyintroducedtimedelay.Iftheproductiscontrolledviaexternalorders,thistimeis
measured from the moment when the order is received to the opening of the main contacts.
3. Contact transfer time (CTT) – IEC 60947-6-1 §3.2.5
This time is measured from the parting of one set of main contacts from one power supply to the closing of a second set of
main contacts on an alternative power supply; this is the duration between the opening of the contacts on the initial position
andtheclosingofthecontactsonthepositionreached,inotherwords,itisthetimein0(disconnectiontime).
