PV SV PV PV Flashing Lights up Alarm code Flashing Accumulated time Displayed item . Set values vary depending on the model. Convenient Functions �� Unit conversion function The unit can be changed between °C and °F and MPa and PSI. �� Timer operation function Timer for ON and OFF can be set in units of 0.5 h up to 99.5 h. Ex.) Can set to stop on Saturday and Sunday and restart on Monday morning. �� Low tank level detecting function The reduction of the fluid level in the tank is notified by alarm code. �� Power failure auto-restart function Automatic restart from stoppage due to power failure, etc. is possible without pressing the key and remote operation. �� Key-lock function Can be set in advance to protect the set values from being changed by pressing keys by mistake. �� Function to output a signal for completion of preparation Notifies by communication when the temperature reaches the pre-set temperature range. �� Anti-freezing operation function If the temperature approaches freezing point, e.g. in winter at night, the pump operates automatically and the heat generated by the pump warms the circulating fluid, preventing freezing. �� Independent operation of the pump The pump can be operated indepnedently while chiller is powered off. You can check piping leak and remove the air. Orange indicator lights up. Red indicator lights up. Timer The time remaining can be checked. Ex. SE.02 “ON timer” Self Diagnosis and Check Display for Easy Maintenance Display of 35 types of alarm codes Operation is monitored all the time by the integrated sensor. Should any error occur, the self diagnosis result is displayed by the applicable alarm code from 35 types. This makes it easier to identify the cause of the alarm. Can be used before requesting service. Changeable alarm set values Setting item Circulating fluid discharge temperature rise Circulating fluid discharge temperature drop Circulating fluid discharge pressure rise Circulating fluid discharge pressure drop Set value 5 to 48°C 1 to 39°C 0.05 to 0.75 MPa. 0.05 to 0.18 MPa. Ex. AL01 “Low level in tank” Alarm codes notify of checking times. Notifies when to check the pump and fan motor. Helpful for facility maintenance. Check display The internal temperature, pressure and operating time of the product are displayed. . The fan motor is not used in water-cooled refrigeration. . These are displayed only for air-cooled refrigeration. Ex. AL28 “Pump maintenance” Ex. drv. “Accumulated operating time” Displayed item Circulating fluid outlet temperature Circulating fluid return temperature Compressor gas temperature Circulating fluid outlet pressure Compressor gas discharge pressure Compressor gas return pressure Accumulated operating time Accumulated operating time of pump Accumulated operating time of fan motor.
