8.3. Operating Sequences
The given times are: operating transfer time, product opening time and contact transfer time. The
definitions 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 configured 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).
