4.2.2 Operation restart when alarm is generated

This product has two types of operation depending on the alarm being generated.

The restart is different depending on the operation mode.

[ 1 ] When the following alarm occurs, this product stops.

・AL01：Low level in tank ・AL17：flow rate failure ・AL18：High circulating fluid discharge temp ・AL19：High circulating fluid return temp. ・AL21：High circulating fluid discharge pressure ・AL24：Memory abnormal ・AL27：forced a stop ・AL30： refrigerant circuit abnormal ・AL31：sensor abnormal ・AL32： controller abnormal

After resetting the alarm (Refer to 「10. How to Reset Alarms 」) when resuming operations press and hold the. [RUN／STOP] key for approximately 1 second. (Refer to “Chapter 7 Alarm Notification and Troubleshooting“)

[ 2 ] When alarms except those shown above are generated the compressor stops, and the

circulating fluid pump continues running for a fixed time (*). At this time, the "RUN" lamp flashes. In case of resetting the alarm (Refer to 7.3 "What to do when an alarm occurs") while the pump is operating, pressing the "RUN / STOP" key once (1 second) causes the compressor to operate and the operation of the product will resume. (This operation only occurs when this function is set. For details, refer to 5.3.6 Alarm Setting Menu. )
