Keep the jumper because it may be needed in the future. T place a jumper in the installed psitin, place the jumper n bth pins (Figure 9). Jumper blcks J2 and J3 establish input mdes and wrk in cnjunctin with ptentimeters P1 and P2. See Selecting an Input Mde. Jumper Pins Jumper Blck Remved (psitined n ne pin) Installed (psitined n bth pins) Jumpers n J7 and J8 must be set fr the crrect input vltage range and number f input devices. (See Table 4.) Jumper blck J7 sets the vltage range fr the input signal(s). If the jumper n jumper blck J7 is incrrectly set, the cntrl may perate in an unexpected manner. See Trubleshting. Jumper blck J8 selects the number f input signals used. When dual inputs are selected, Terminal 3 f TB3 (TB3-3) is enabled. The VFD66 cntrl varies the speed f the fan mtr in accrdance with the higher value f the tw input signals received. If the jumper n jumper blck J8 is incrrectly set, the cntrl may perate in an unexpected manner. See Trubleshting. Jumper blck J9 selects maximum frequency utput f the cntrl. Remve the jumper fr 50 Hz mtrs, typically used in Eurpe. Install the jumper fr 60 Hz mtrs, typically used in Nrth America. Pwer t the VFD66 cntrl must be discnnected and recnnected befre frequency changes take effect. De-Rating the VFD66 Cntrl fr High Temperatures and High Altitudes Ambient air temperature and altitude f the installatin affect the maximum utput ampere rating f the VFD66 cntrl. High air temperature makes the heat sink less effective in dissipating the generated heat. High altitudes have thinner air than lwer altitudes, which is less effective in dissipating heat. The less effective the heat sink is, the lwer the maximum utput ampere rating f the VFD66 cntrl. Temperature De-Rating Fr temperatures up t 122 F (50 C), the maximum utput ampere rating is unaffected by temperature. At temperatures between 122 F (50 C) and 140 F (60 C), the maximum utput ampere rating is decreased. The VFD66 cntrls are nt designed t perate in temperatures abve 140 F (60 C). See Figure 10 fr temperature de-rating fr 208/230 VAC mdels. See Figure 11 fr temperature de-rating fr 400/460 VAC mdels. Figure 9: Jumper Placement n Pins Jumper blcks J5 and J6 have jumpers installed n the tw middle pins f each jumper blck. These jumpers activate the internal ptentimeters. Mving the jumpers frm the factry-installed psitin disables the internal ptentimeters. 6 VFD66 Series Cndenser Fan Speed Cntrls Prduct/Technical Bulletin

See Figure 10, Figure 11, and Table 5. If a VFD66Exx type (208/230 VAC) is used and the temperature is belw 122 F (50 C), the VFD66 cntrl may be used fr lads up t 10.6 amperes at any altitude belw 3300 ft (1000 m). If the temperature arund the VFD66 cntrl reaches 140 F (60 C), the rating is different. Accrding t Figure 10, the VFD66 cntrl is rated fr nly 7.5 amperes at 140 F (60 C). If the VFD66 cntrl is used in Denver, Clrad (altitude 5200 ft), the utput rating is reduced. (See Table 5.) When the temperature is less than 122 F (50 C), the VFD66 cntrl is rated fr 9.96 amperes, as shwn by the equatin: De-Rated Maximum Output Amperes = 10.6 Amperes x 0.94 = 9.96 Amperes If the VFD66 cntrl is used in Denver, Clrad (altitude 5200 ft), and the ambient temperature reaches 140 F (60 C), then the VFD66 cntrl is de-rated t a 7.5-ampere maximum current draw due t the high ambient temperature and is further de-rated t 7.05 amperes f current draw because f high altitude. De-rated Maximum Output Amperes = 7.5 Amperes x 0.94 = 7.05 Amperes VFD66 Series Cndenser Fan Speed Cntrls Prduct/Technical Bulletin 7

Turning P1 Clckwise (CW) increases minimum speed setting, Cunterclckwise (CCW) decreases minimum speed setting. P2 determines whether the mtr idles at minimum speed r shuts ff at minimum speed. P2 must be set at full CCW r full CW psitin; intermediate settings have n effect. Figure 12 illustrates three pssible mtr speed curves. When P2 is rtated fully CCW, the mtr idles at the minimum speed set by P1 at input values belw the end f the prprtinal band (Curve A in Figure 12). When P2 is rtated fully CW, the mtr shuts ff at the minimum speed set by P1 when the input is belw the bttm end f the prprtinal band (Curve B in Figure 12). In Curve C, the minimum mtr speed (P1) is set at 0% f maximum mtr speed and the psitin f P2 has n effect. 8 VFD66 Series Cndenser Fan Speed Cntrls Prduct/Technical Bulletin

Ratimetric transducers vary the signal vltage frm 10-90% f the 5 VDC supply pwer as the pressure ges frm minimum t maximum f the transducer rating. Nte: Nn-ratimetric transducers generate mre errr than ratimetric transducers. 0-10 VDC P499 transducers are nt ratimetric. The J7 jumper psitin sets the input signal vltage range. Install the J7 jumper when using a 0-5 VDC transducer. Remve the J7 jumper when using a 0-10 VDC transducer. Nte: Applicatins using 0-10 VDC transducers require a separate 15 VDC pwer supply. The J3 jumper psitin establishes the lw r high pressure range f P1 (Table 9). P1 adjusts the pressure setpint and establishes the pressure value at which the VFD66 cntrls drive the fan mtr at maximum speed. P2 adjusts the prprtinal band ver which fan mtr speed is cntrlled. Figure 13 illustrates J3, P1, and P2 settings in Electrnic Pressure Transducer Input mde with a P499 transducer (0-500 psi).

Operatin The VFD66 cntrls feature tw diagnstic LEDs: POWER and ALARM. (See Figure 14.) The POWER LED illuminates when pwer is applied t the VFD66 cntrls. When pwer is discnnected frm the VFD66 cntrls, this LED remains illuminated while the pwer supply capacitrs discharge. If the mtr is nt running when pwer is remved, the LED may remain illuminated fr up t 5 minutes, while the capacitrs discharge. The ALARM LED indicates fault cnditins and prvides diagnstic infrmatin. Cnstant illuminatin f this LED indicates that the mtr is verladed and the VFD66 cntrl shuts dwn the mtr. When the ALARM LED flashes, the VFD66 cntrl has shut dwn the mtr. The number f times the ALARM LED flashes indicates the cause f the fault. (See Trubleshting.)

The VFD66 cntrl adjusts the utput frequency t match the available input pwer. (See Figure 15 and Figure 16.) 10 VFD66 Series Cndenser Fan Speed Cntrls Prduct/Technical Bulletin
Examples These examples use a VFD66 cntrl rated fr 400/460 VAC at 50/60 Hz. The cntrl is used in Nrth America, s the maximum supply vltage is 460 VAC at 60 Hz. If the supply vltage is 460 VAC (100% f 460 VAC), the VFD66 cntrl runs the mtr at full speed (460 VAC at 60 Hz). If the supply vltage drps t 368 VAC (80% f 460 VAC), the VFD66 cntrl can nly prvide 368 VAC and the cntrl reduces the utput frequency t 53 Hz. If the supply vltage drps t 276 VAC (60% f 460 VAC), the VFD66 cntrl can nly prvide 276 VAC and the cntrl reduces the utput frequency t 40 Hz. If the supply vltage drps belw 276 VAC (60% f 460 VAC), then the VFD66 cntrl stps the mtr and des nt restart it until the supply vltage rises t at least 276 VAC. Unexpected Operatin If the VFD66 cntrl perates in an unexpected manner, check the jumper psitin n jumper blcks J7 and J8. See Figure 3, Table 10, and Table 11 fr pssible peratin scenaris when the jumper psitin is nt crrect fr the input device cnnected t the VFD66. Table 10: Pssible Operatin Scenaris Related t Jumper Blck J7 If the cntrl is set fr. 0-10 VDC (J7 jumper installed) 0-5 VDC (J7 jumper remved) And if the cntrl receives. The result is 0-5 VDC the VFD66 cntrl nly drives the mtr at half f the full mtr speed. 0-10 VDC the VFD66 cntrl nly uses 0-5 VDC and the mtr reaches full speed when the input signal is at 5 VDC. Table 11: Pssible Operatin Scenaris Related t Jumper Blck J8 If the cntrl is set fr. ne input (J8 installed) ne input (J8 installed) tw inputs (J8 remved) tw inputs (J8 remved) And input devices are used tw nne ne nne The result is. the secnd input device is ignred. the VFD66 cntrl runs the mtr at full speed nly. the VFD66 cntrl runs the mtr at full speed. the VFD66 cntrl runs the mtr at full speed nly. Shutdwn The ALARM LED indicates fault cnditins and prvides diagnstic infrmatin. Cnstant illuminatin f this LED indicates that the mtr is verladed and the VFD66 cntrl shuts dwn the mtr. When the ALARM LED flashes, the VFD66 cntrl has shut dwn the mtr. The number f times the ALARM LED flashes indicates the cause f the fault. See Table 12. After shutdwn, there is a 30-secnd time delay befre the VFD66 cntrl initiates an autmatic restart. The result is ne f the fllwing: If the fault cnditin is crrected, the VFD66 cntrl cntinues t perate. After 500 secnds, the fault rutine resets autmatically. If the fault persists, the VFD66 cntrls lck ut again, requiring reset. Resetting a Lcked-Out VFD66 Cntrl T reset a lcked-ut VFD66 cntrl, fllw the prcedure belw: 1. Discnnect pwer frm the VFD66 cntrl. 2. Wait 5 minutes t allw the internal capacitrs t fully discharge. 3.

Selecting a Mtr IMPORTANT: D nt exceed the VFD66 cntrl s maximum utput ampere rating. Exceeding the cntrl s maximum utput ampere rating can cause the VFD66 cntrl t shut dwn n an verlad fault. The VFD66 cntrl allws the mtr t develp trque that varies with the current. The mtr prvides maximum trque at its maximum current draw. Use these guidelines t select the prper mtr fr use with the VFD66 cntrl.! CAUTION: Risk f Equipment Damage. Mtrs used with the VFD66 cntrls must meet certain specificatins fr prper perfrmance and peratin. Mtrs that d nt meet these specificatins may be damaged. Required Mtr Specificatins Mtrs used with the VFD66 Series Cntrls must: have variable trque peratin be UL Recgnized and CSA Certified, r equivalent be AC inductin 3-phase mtrs be rated fr 208/230 VAC, 60 Hz (230 VAC, 50 Hz) r 460 VAC, 60 Hz (400 VAC, 50 Hz) have ball bearings have an Inverter Rating (400/460 VAC mtrs) have Insulatin Class F r better On 400/460 VAC mdels, the mtr insulatin system must be deemed suitable by the mtr manufacturer fr use n PWM (Pulse Width Mdulated) IGBT (Insulated Gate Biplar Transistr) variable frequency drives. These are als referred t as inverter-rated mtrs. The VFD66 cntrls are suitable fr use with thermally prtected mtrs r mtrs intended by their manufacturer fr fan speed mdulating applicatins. Multiple Mtrs A VFD66 cntrl can cntrl multiple mtrs; hwever, the sum f the Full Lad Amperes (FLA) ratings fr the mtrs must nt exceed the maximum utput amperage rating f the VFD66 cntrl, including any de-rating due t altitude and/r temperature. Ordering Infrmatin T select the prper mdel f the VFD66 cntrl fr a specific applicatin: 1. Lcate the nameplate (dataplate) n the mtrs intended fr use with the VFD66 cntrl. 400/460 VAC mtrs fr use with the VFD66 cntrls must be inverter-rated mtrs. See Selecting a Mtr fr further infrmatin. 2. Identify the FLA ratings f each mtr t be cntrlled by the VFD66 cntrl. If mre than ne mtr will be cntrlled, add the ratings f all the mtrs t determine the ttal FLA. 3. Adjust the VFD66 cntrl s current rating fr temperature and altitude. See De-Rating the VFD66 Cntrl fr High Temperatures and High Altitudes. 4. Cmpare the sum f the amperage draw f the mtrs t the adjusted current rating f the VFD66 cntrl. If the current required is between tw VFD66 cntrl mdels, select the mdel with the higher amperage rating. 5. Cnfigure the prduct number f the desired VFD66 cntrl by adding the apprpriate 3-letter suffix t VFD66. See fr prduct number cnfiguratin. See Table 15 fr standard mdels.
