摘要： The air circulation fan associated with a radiator of some machines may include an automatic reversing purge cycle that is utilized to dislodge material from the radiator and/or intake screen of the cooling system housing. The purge cycle is locked out when a person may be in the vicinity of the air intake screen of the machine. A controller determines that a person may be in the vicinity of the air intake screen when the machine is idle stationary, such as by determining that a parking brake is engaged. By locking out the purge cycle during machine idle stationary conditions, the risk of blowing dislodged dirt and/or debris onto a person, who may be servicing the machine or accessing an operator station, can be avoided.

摘要翻译： 与一些机器的散热器相关联的空气循环风扇可以包括用于从冷却系统壳体的散热器和/或进气屏幕移走材料的自动换向吹扫循环。 当人员可能在机器进气屏幕附近时，清洗循环被锁定。 当机器怠速静止时，例如通过确定驻车制动器被接合，控制器确定人员可能在吸气屏幕附近。 通过在机器怠速静止条件下锁定清洗循环，可以避免将可能正在维修机器或操作员站的人员吹走掉的污垢和/或碎屑的风险。
