1. Xa unikezelo lwamandla okusebenza lwecandelo I no-II lwe kupholile ilahlekile, umqondiso we “#1, #2 ukusilela kobonelelo lwamandla” uthunyelwa ngaphandle, kwaye i-transformer engundoqo epholileyo epholileyo yohambo lwesekethe iqhagamshelwe. Kufuneka kuxelwe kwi-dispatcher ngokukhawuleza, kwaye isethi yokukhusela kufuneka ivaliwe.

2. Xa ukutshintshwa kwamandla okusebenza kwinqanaba le-I kunye ne-II lihluleka ngexesha lokusebenza, “i-cooler full stop” ivuliwe, kwaye i-transformer ephambili ye-cooler full stop trip circuit ixhunyiwe ngeli xesha. Kufuneka kuxelwe ngokukhawuleza kwi-dispatcher ukukhubaza le setethi yokukhusela, kwaye umsebenzi wencwadana kufuneka uqhutywe ngokukhawuleza. Ukutshintsha, okufana ne-KM1, ukusilela kwe-KM2, akunakuba kukuvuselela ngamandla.

3. Xa nayiphi na enye yeesekethi ezipholileyo isilela, yahlula i-cooler circuit yodwa.
