hen the timer is started, then this switch has no effect. S2 is centrally located in the off switch, the timer can switch through the conversion is completed: Charge - open - discharge. Since midway stop charging, even if not to the timer set time, the charging station will return to work status timer output lines. When the C discharge, R/C terminal voltage is zero, the discharge position waiting for start signal S1. Even if the recovery position. Work status timer output line does not change, therefore, the timer is reset when the work which the state remains the same output line, in this moment, C starts charging again, start a timer to change working hours.
