3.2.1 Water supply process (Inlet)
In this platform, the s/w just use “ 0 ” and “ 1 ” to judge washer water level, “ 0 ” indicates water
does not reach user setting value, “ 1 ” indicates the water reached the user setting value. Below are
the water supply function details:
While inlet process starting, the Inlet triac switched on and supply water to user setting water
level, the time set for inlet process is 2 minutes, while this process exceeds 2 minutes, washing
program will stop time counting; and if this process finished in less than two minutes, the
process running time still calculated as 2 minutes.
While water level does not reach the user setting value in 20 minutes, platform will alarm and
start to run error processing program.
During “ soak ”, “ wash ” and “ rinse ” process, if water level drop one or more levels lower
than user setting value, platform will pause current process and start inlet process, the process
running time counting is stopped at this time. While the platform executing the last time rinse
inlet, the softener inlet valve switched on for 10 seconds at the same time the inlet valve
switched on. While water level does not reach the user setting value in 20 minutes, platform
will alarm and start to run error processing program.
