1 Scope
This part of IEC 62386 specifies a bus system for control by digital signals of electronic lighting equipment which is in line with the requirements of IEC 61 347 (all parts), with the addition of DC supplies. This document is only applicable to IEC 62386-102:2014 and IEC 62386-102:2014/AMD1:— control gear that implements thermal gear protection. NOTE Requirements for testing individual products during production are not included.

9 Method of operation
9.1 General The requirements of IEC 62386-102:2014 and IEC 62386-102:2014/AMD1:—, Clause 9 apply with the following additions. 9.2 Thermal gear behaviour Depending on the control gear temperature, various states can be identified within a control gear: • Normal: the control gear temperature is in the defined temperature ranges. • Overload: the control gear temperature exceeds the defined overload temperature threshold (T ovl ). • Shutdown: the control gear temperature exceeds the defined shutdown temperature threshold (T shut ). All possible state transitions are illustrated in Figure 2.Starting from a normal state, if the control gear temperature rises above T ovl , the control gear shall enter the overload state. If the control gear temperature increases even more, rising above T shut , the control gear shall enter the shutdown state. When the control gear temperature drops below (T shut – H shut ), but above T ovl , the control gear shall return to the overload state. When the control gear temperature drops below (T ovl – H ovl ), the control gear shall return to the normal state. Figure 3 illustrates this case.
