Figure 2. Motor Speed versus Pressure Ramp for 0–750 PSI Transducer

PL = 262 PSI; PH = 420 PSI; C 3, C 4, C 6, and C 7 use default settings.

Figure 5. Motor Speed versus Pressure Ramp for 0–500 PSI Transducer

PL = 170 PSI; PH = 260 PSI; Calculate new values for C 3 and C 4. When connecting a second P499V transducer, then also change Parameter C 6 to 3.4V and change C 7 to 5.2V.

Figure 7. Motor Speed versus Pressure Ramp for 0–500 PSI 4–20 mA Transducer

PL = 135 PSI; PH = 219 PSI; Calculate new values for C 6 and C 7.
The C450CQN can use temperature, pressure, or humidity to control the VFD68 output to a motor. Set the AI2 mode switch to V.
