Enables remote operation (start and stop) by communication. Lights up during remote operation. Lights up when the product is started, and goes off when it is stopped. Flashes during stand-by for stop or anti-freezing function, or independent operation of the pump. Flashes with buzzer when alarm occurs. Lights up when the surface of the fluid level indicator falls below the L level. Equipped with a timer for start and stop. Lights up when this function is operated. Equipped with a power failure auto-restart function, which restarts the product automatically after stopped due to a power failure, is provided. Lights up when this function is operated. Makes the product start or stop. Changes the item in menu and enters the set value. Decreases the set value. Increases the set value. Press the [MENU] and [RUN/STOP] keys simultaneously. The pump starts running independently to make the product ready for start-up (release the air). Press the [�云 and [��] keys simultaneously. The alarm buzzer is stopped and the [ALARM] indicator is reset. Shifts the main menu (display screen of circulating fluid discharge temperature and pressure) and other menus (for monitoring and entry of set values). Displays the circulating fluid current discharge temperature and pressure and alarm codes and other menu items (codes). Displays the circulating fluid discharge temperature and the set values of other menus. No. Description Function PV SV Alarm This unit has 35 types of alarms as standard, and displays each of them by its alarm code on the PV screen with the [ALARM] lamp ([LOW LEVEL] lamp) lit up on the operation display panel. The alarm can be read out through communication. .1 “Stop” or “Continue” are default settings. Customers can change them to “Continue” and “Stop”. For details, read the Operation Manual. .2 “AL19, AL31, AL32” are disabled in the default setting. If this function is necessary, it should be set by the customer referring to the Operation Manual. .3 For water-cooled models, the alarm is not activated. .4 This alarm function can be used when the option (sold separately) is used.
