20Table 7 — Blower Data — 50HQP120 (cont)LEGEND NOTES:1. A = Standard Rpm/Standard Motor, B = Low Rpm/Standard Motor, C =High Rpm/Standard Motor.2. Unit factory shipped with standard static sheave and drive at 2.5 turnsopen. Other speed require field selection.3. For applications requiring higher static pressures, contact your local rep-resentative. Performance data does not include drive losses and is basedon sea level conditions.4. All airflow is rated at lowest voltage if unit is dual voltage rated, i.e., 380Vfor 380/420V units.5. Airflow in l/s with wet coil and clean filter.FIELD SELECTABLE INPUTSJumpers and DIP (dual in-line package) switches on thecontrol board are used to customize unit operation and can beconfigured in the field.Complete C Control Jumper Settings (SeeFig. 12)WATER COIL FREEZE PROTECTION (FP1) LIMITSETTING — Select jumper 3, (JW3-FP1 Low Temp) tochoose FP1 limit of –12.2 C or –1.1 C. To select –1.1 C as thelimit, DO NOT clip the jumper. To select –12.2 C as the limit,clip the jumper.AIR COIL FREEZE PROTECTION (FP2) LIMIT SET-TING — Select jumper 2 (JW2-FP2 Low Temp) to chooseFP2 limit of –12.2 C or –1.1 C. To select –1.1 C as the limit,DO NOT clip the jumper. To select –12.2 C as the limit, clipthe jumper.ALARM RELAY SETTING — Select jumper 1 (JW1-AL2Dry) for connecting alarm relay terminal (AL2) to 24 vac (R) orto remain as a dry contact (no connection). To connect AL2 toR, do not clip the jumper. To set as dry contact, clip the jumper.Complete C Control DIP Switches — The Com-plete C Control has 1 DIP switch block with five switches. SeeFig. 12.PERFORMANCE MONITOR (PM) — DIP switch 1 willenable or disable this feature. To enable the PM, set the switchto ON. To disable the PM, set the switch to OFF.STAGE 2 — DIP switch 2 will enable or disable compressordelay. Set DIP switch to OFF for stage 2 in which the compres-sor will have a 3-second delay before energizing.NOTE: The alarm relay will not cycle during Test mode ifswitch is set to OFF, stage 2.DIP SWITCH 3 — not used.DIP SWITCH 4 — not used.DIP SWITCH 5 — DIP switch 5 is used to initiate 1 or 3 triesfor the FP1 fault. If water freeze protection for the water coilthen DIP switch 5 can be set to lockout on the FP1 fault afterone try.Deluxe D Control Jumper Settings (SeeFig. 13)WATER COIL FREEZE PROTECTION (FP1) LIMITSETTING — Select jumper 3, (JW3-FP1 Low Temp) tochoose FP1 limit of –12.2 C or –1.1 C. To select –1.1 C as thelimit, DO NOT clip the jumper. To select –12.2 C as the limit,clip the jumper.AIRFLOW(l/s)EXTERNAL STATIC PRESSURE (Pa)0 25 50 75 100 125 150 175 200 225 250 275 300 325 350 3751605BkW 0.79 0.85 0.89 0.94 0.99 1.04 1.08 1.12 1.17 1.23 1.29 1.35 — — — —Sheave/Mtr A A A A A A A C C C C C — — — —RPM 755 790 820 855 890 920 945 975 1005 1035 1060 1090 — — — —Turns Open 5 4.5 3.5 3 2 1.5 1 3.5 3 2 1.5 1 — — — —1652BkW 0.87 0.91 0.96 1.02 1.06 1.11 1.15 1.20 1.24 1.29 1.34 — — — — —Sheave/Mtr A A A A A A C C C C C — — — — —RPM 780 810 845 880 910 940 970 1000 1025 1050 1080 — — — — —Turns Open 4.5 4 3 2.5 2 1 3.5 3 2.5 2 1 — — — — —1699BkW 0.94 0.99 1.04 1.09 1.15 1.20 1.25 1.30 1.35 1.40 1.45 — — — — —Sheave/Mtr A A A A A C C C C C C — — — — —RPM 805 835 870 900 930 960 990 1015 1045 1070 1100 — — — — —Turns Open 4 3.5 2.5 2 1.5 3.5 3 2.5 2 1.5 1 — — — — —1746BkW 1.01 1.05 1.10 1.16 1.21 1.26 1.32 1.37 1.43 1.49 — — — — — —Sheave/Mtr A A A A A C C C C C — — — — — —RPM 825 855 885 915 945 975 1005 1030 1060 1085 — — — — — —Turns Open 3.5 3 2.5 1.5 1 3.5 3 2 1.5 1 — — — — — —1794BkW 1.07 1.11 1.17 1.22 1.27 1.33 1.38 1.45 1.51 1.57 — — — — — —Sheave/Mtr A A A A C C C C C C — — — — — —RPM 840 870 900 930 960 990 1015 1045 1070 1095 — — — — — —Turns Open 3.5 2.5 2 1.5 3.5 3 2.5 2 1.5 1 — — — — — —1841BkW 1.17 1.21 1.27 1.32 1.38 1.43 1.49 1.55 1.62 — — — — — — —Sheave/Mtr A A A A C C C C C — — — — — — —RPM 860 885 915 945 975 1005 1030 1055 1085 — — — — — — —Turns Open 3 2.5 1.5 1 3.5 3 2 1.5 1 — — — — — — —1888BkW 1.23 1.29 1.35 1.41 1.48 1.53 1.60 1.66 1.72 — — — — — — —Sheave/Mtr A A A C C C C C C — — — — — — —RPM 875 900 930 960 990 1015 1045 1070 1095 — — — — — — —Turns Open 2.5 2 1.5 3.5 3 2.5 2 1.5 1 — — — — — — —— — Operation Not RecommendedBkW — Brake KilowattsESP — External Static PressureRPM — Revolutions Per MinuteA — Units with Standard Static/Standard Motor OptionB — Units with Low Static/Standard Motor OptionC — Units with High Static/Standard Motor OptionIMPORTANT: Jumpers and DIP switches should only beclipped when power to control board has been turned off.
