After boot controller meets the conditions in order to implement the cleaning operation control device for each room. When each chamber cleaning operations are completed a second pulse controller Which is better, to determine whether the conditions to meet the cinder offline pulse control device, such as the meet began cinder, satisfied, into the cycle interval delay. Length of the delay is determined by the "periodic intervals." When the end of the delay period interval digital pulse controller, into a new round of cleaning operations. After nine brands are brightly powered pulse controller automatically without any action by the latest set parameters to exercise control. The control device has five major state - standby, running, POST status, manual maintenance status, control parameter modification status. Pulse controller with clean compressed air energy Geng, pneumatic pulse signal output, instead of supporting the use of a pneumatic valve, pulse valve, such as pneumatic pulse controller is constituted by a pneumatic pulse combination meter. Characterized by pulse width and pulse period can be adjusted, can achieve automatic control, pneumatic control is relatively easy to grasp. The disadvantage is that period and width in use would change after a period of use, easy to adjust, maintenance workload: Requires a clean environment, operating temperature between -5 ~ 50 ℃; require compressed air.
