English to Portuguese Tech/Engineering Electronics / Elect Eng air conditioning

The term appears in a control board manual, in the "Analogue outputs" configuration table. The whole sentence is" 1= Output configured as Triac (for pulse pilot)". I'm pretty sure "pulse" refers to "impulso", as in " duração do impulso". In the Italian version the term is "per pilotaggio ad impulsi" and in German it is "für Impulssteuerung". Now, the terms "pilot/pilotaggio/Steuerung" have already appeared several times in the text, and it's really refering to "controlo". But I'm not too sure about " controlo dos impulsos", as it resembles Mr. Freud a bit too much:) any suggestions? thank you
