### Asset Description:
Pump: A device used to move fluid or gas from one place to another. It can include various types of pumps, such as centrifugal pumps, positive displacement pumps, and diaphragm pumps.

### Conditions:
- Pump Running
- SubType NOT HW
- Pump Motor VFD Output % > 35%
- Pump Motor VFD Output % = Daily Average Pump Motor VFD Output %
- OAT < 95 °F
- ABS(Pump Differential Pressure - Pump Differential Pressure Setpoint) > 4psi IF Reporting

### How long the conditions were met:
Met for 2 Hours

Analyse the given conditions of the presented asset and select the option that MOST likely gives the reason for the conditions?
A. Lighting relay schedule over written
B. Mis-sized equipment
C. Unit bypassing or blowing off too much air
D. Static pressure sensors need calibration, repair or replacement


# Answer

Answer: D. Static pressure sensors need calibration, repair or replacement

Guidance Rationale: Given that the pump is running and the motor’s variable frequency drive (VFD) output percentage is both above 35% and equal to the daily average,
this indicates that the pump is operating under stable and expected load conditions. However, there is a significant deviation in the pump differential pressure from its setpoint,
exceeding 4 psi, which points to a potential issue in how pressure is being measured. Since the outside air temperature is below 95 °F, it is unlikely that environmental conditions are responsible for the discrepancy.

Therefore, the most likely explanation is that the static pressure sensors require calibration, repair, or replacement,to ensure accurate readings and efficient pump operation.
