	E1 Reverse Phase Occurs when connection of power cord is in reverse phase. Before starting work, turn power breaker off. Always connect earths. After work, securely tighten connections. Of the three lines of the power cords, change hook-up of two lines and turn power breakers on. If problem persists Return to top of the page
	E2 Dry Blower Overload Occurs when overcurrent flows through the blower and the overload relay of the electromagnetic switch trips. Blower is Overloaded and Overload Relay Trips If problem persists Return to top of the page
	E3 Convey Blower Overload Occurs when overcurrent flows through the blower and the overload relay of the electromagnetic switch trips. Blower is Overloaded and Overload Relay Trips If problem persists Return to top of the page
	E4 Dry Temperature Upper Limit Occurs when the dry temperature rises above the set and upper limit temperature. Operation will stop automatically. Check upper temperature settings. If pressing SV switch for more than five seconds, unit will enter Engineering Setting Mode. Display will change every time SV switch is pressed during this mode. [Point] Setting Range 0~40 degrees C   Original Setting 10 degrees C Overheat Alarm See for reference Engineering Mode Parameters If problem persists Return to top of the page
	E5 Broken Dry Sensor Occurs when wiring or drying thermocouple (CA sensor) for the process (hopper) temperature controller is broken. Operation stops automatically. Check to see if either the thermocople (CA sensor) is bent, damaged or if wiring is disconnected. If problem persists Return to top of the page
	E7 No. 1 Conveying Malfunction Alarm occurs when hopper does not fill within a set time after start-up of No. 1 Direction conveying. Also occurs when 1st conveying is not done despite repeated 2nd conveying. Need to adjust all sensors in primary or secondary side.
