Abstract

In some implementations, a controller (126) may receive an input that indicates a proportion of a spray cycle in which a fluid spray system (200) is to be active. The fluid spray system (200) may include at least a first fluid pump (128) configured to supply fluid to a first fluid spray bar (122) and a second fluid pump (130) configured to supply fluid to a second fluid spray bar (124). The controller (126) may determine, in accordance with the proportion, a spraying timing for the first fluid pump (128) and the second fluid pump (130) that minimizes an overlap of an active time of the first fluid pump (128) and an active time of the second fluid pump (130), and/or an overlap of an inactive time of the first fluid pump (128) and an inactive time of the second fluid pump (130). The controller (126) may cause activation of the first fluid pump (128) and the second fluid pump (130) in accordance with the spraying timing.
