74Table 13 — Job Site Parameters*With variable flow systems this point may be configured to the lowerend of the range.NOTE: Other parameters: Screens are normally left at the defaultsettings; they may be changed by the operator as required. The timeand persistence settings on the VFD_CONF table can be adjustedto increase or decrease the sensitivity to a fault condition. Increasingtime or persistence decreases sensitivity. Decreasing time or per-sistence increases sensitivity to the fault.INPUT EQUIPMENT SERVICE PARAMETERS IF NEC-ESSARY — The EQUIPMENT SERVICE table has sixservice tables.VERIFY VFD CONFIGURATION AND CHANGEPARAMETERS IF NECESSARY (Fig. 40)VFD CHILLER FIELD SET UP AND VERIFICATIONLabel Locations — Verify that the following labels have beeninstalled properly and match the chiller requisition:• Surge Parameters — Located inside the control panel. SeeFig. 14.• Refrigeration Machine Nameplate — Located on the rightside of the control panel. See Fig. 14.• External Machine Electrical Data Nameplate — Located onthe right side of the VFD as viewed from its front. SeeFig. 40.• Internal Machine Electrical Data Nameplate — Located onthe inside of the left VFD enclosure door. See Fig. 40.• Record all nameplate information on the Initial Start-upChecklist at the end of this manual.PARAMETER TABLEMotor Nameplate Voltage VFD_CONF - from chiller information nameplateCompressor 100% Speed VFD_CONF - from chiller information nameplateLine Freq=60 Hz?

Enter 0 otherwise.Minimum Load Points (Tsmin, IGVmin) OPTIONS - Per Chiller Requisition (Tsmin, IGVmin) per job data - See ModifyLoad Points section. Refer to table located in the control panel.FULL (Maximum) load points (TsMax, IGVmax) OPTIONS - Per Chiller Requisition (Tsmax, IGVmax) per job data - See ModifyLoad Points section. Refer to table located in the control panel.Surge Line Shape Factor OPTIONS - Per Chiller Requisition. Refer to table located in the control panel.Chilled Medium SETUP1 - Enter Water or BrineEvaporator Refrigerant trippoint SETUP1 - Usually 3 F (1.7 C) below design refrigerant temperature*Evaporator Flow Delta P cutout SETUP1 - Per Chiller Requisition if available or enter 50% of design pressuredropCondenser Flow Delta P cutout SETUP1 - Per Chiller Requisition if available or enter 50% of design pressuredropHigh Condenser Water Delta P Enter the maximum value for the condenser water pressure drop if chiller isconnected to a condenser water manifold system. Otherwise leave at default.Diffuser Option (compressors with Split Ring Diffusers) SETUP2 - ENABLE for 4 and 5 frame compressors with Split Ring Diffusers.See table in control panel for values.Diffuser Full Span mA (Compressors with Split RingDiffusers)SETUP2 - Enter diffuser actuator full span mA value for 4 and 5 frame compres-sors with Split Ring Diffusers. See label on side of diffuser actuator for values.IMPORTANT: The VFD controller has been factory config-ured for use and communications to the International ChillerVisual Controller (ICVC). Some parameters are specific tothe chiller configuration and will need to be verified prior tooperation. All command functions must be initiated fromthe ICVC.:Fig. 40 — Machine Electrical Data NameplateINTERNAL EXTERNALa19-1626
