Series HRZ Options Rc3/4 DI tube (1 piece each attached for IN/OUT) DI filter (Optional accessories) (Refer to page 1340.) . Please order separately. Approx. 156 mm Analog Communication Option symbol C HRZ C DeviceNet Communication Option symbol D HRZ D DI Control Kit Option symbol Y HRZ Y NPT Fitting Option symbol N HRZ N Analog communication In addition to the standard contact input/output signal communication and the serial RS-485 communication, analog communication function can be added. The analog communication function enables to write and read out the following items. Circulating fluid temperature setting Scaling voltage - circulating fluid temperature can be set arbitrarily by the customer. For details, please consult our “Communication Specifications” information. Circulating fluid present temperature Electrical resistivity. . Only when the DI control kit (option Y) is selected. DeviceNet communication In addition to the standard contact input/output signal communication and the serial RS-485 communication, DeviceNet function can be added. DeviceNet function enables to write and read out the following items. Run/Stop Circulating fluid temperature setting Circulating fluid automatic recovery start/stop.1 .1 Only when the circulating fluid automatic recovery function (option Z) is selected. .2 Only when the DI control kit (option Y) is selected. For details, please consult our “Communication Specifications” information. Circulating fluid present temperature Circulating fluid flow Circulating fluid discharge pressure Electrical resistivity.2 Alarm occurrence information Status (operating condition) information NPT fitting An adapter is included to change the connection parts of circulating fluid piping and facility water piping to NPT thread type. The adapter must be installed by the customer. DI control kit Select this option if you want to maintain the electric resistance ratio (DI level) of the circulating fluid at a certain level. However, some components have to be fitted by the customer. For details, refer to specification table for this option. Please note that this is not applicable to the fluorinated liquid type. 60% ethylene glycol aqueous solution 0 to 20 0 to 2.0 Note) 0 to 2.0 HRZ00�ｭ-L1-Y HRZ00�ｭ-H1-Y HRZ00�ｭ-W1-Y HRZ010-W1S-Y HRZ00�ｭ-L2-Y HRZ010-W2S-Y Allowable circulating fluid DI level display range DI level set range DI level reduction alarm set range . MΩ・cm MΩ・cm MΩ・cm Applicable model Deionized water Note) The DI filter is needed to control the DI level. (SMC Part No.: HRZ-DF001) Please purchase additionally because the DI filter is not included in this option. Also, if necessary, additionally purchase the insulating material for the DI filter. (SMC Part No.: HRZ-DF002) . Install the DI filter outside the thermo-chiller for piping. Secure the space for installing the DI filter on the rear side of the Thermo-chiller. . It may go outside of the temperature stability range of ±0.1°C when this option is used in some operating conditions. Note) Options have to be selected when ordering the Thermo-chiller. It is not possible to add them after purchasing the unit. 1342
