User Manual of EM730 Series Inverter keyboard displays SLEEP, and SLEEP disappears automatically after wake-up. It has a sleep indication digital output signal (the Y1 output terminal has been set to: No. 59 function sleep indication), which can be used to control the sleep small pump. Wake-up logic: When the feedback pressure is less than the wake-up pressure (F09.30), after the wake-up delay time (F09.31),wake up. The entire sleep wake-up logic is shown in the figure below. Sleep wake-up logic diagram Notes If you want to select sleep to be effective, please modify F09.27=3 in the shutdown state to seal the dormant pipe. Modification in the running state is invalid.
If debugging finds that the time to enter the dormant state is too long, the F09.46 pressure feedback increment value can be appropriately increased. If F09.27=3 is modified in the shutdown state and it still does not sleep, the PID adjustment dead zone value of F09.47 can be appropriately increased.
