*1. Definition of symbols in the "Error reset" column.
・・・ Errors that can be reset.
・・・ Errors that cannot be reset.
・・・ Errors that will be automatically reset after the cause of the error is removed.
*2. Power supply fault can be detected only when the switch setting "Automatic recovery after power supply fault " on the unit is set to
"Disable." (The default setting is "Enable.")
*3. If a unit comes to a stop due to a preliminary error, the unit will resume normal operation if the error conditions are cleared within a
certain amount of time. If the error conditions persist beyond the predetermined time, the unit will come to an abnormal stop.
*4. " * " shows types of components. (0/1: COMP for MAIN circuit, 2: COMP for SUB circuit, 5: FAN 1, 6: FAN 2, 7: FAN 3)
Display setting (Control board display *)
SW3-3: OFF
High pressure

* Display settings can be either of the MAIN BOX and the SUB box.
Display is switched in the 3 second intervals.
