### 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
- Pump VFD Speed Reporting
- OAT < 95 °F
- ABS(Pump Differential Pressure - Pump Differential Pressure Setpoint) > 4 IF Reporting

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

Looking at the current state of the asset, what is the LEAST likely cause among the options?
A. Fan is overridden
B. Pump is overridden
C. Static pressure sensors need calibration, repair or replacement


# Answer

Answer: A. Fan is overridden

Guidance Rationale: 
Given that the pump is running, the VFD speed is reporting, and the outside air
temperature (OAT) is below 95 °F, we can assume the system is operating under
normal environmental load. However, the absolute difference between the pump
differential pressure and its setpoint exceeds 4 psi, which has persisted for 2
continuous hours. This suggests an issue directly related to the pump’s control
or sensing mechanisms. Possible causes include the pump being overridden or
pressure sensors requiring calibration or repair.

In contrast, the condition "Fan is overridden" does not directly impact pump performance or pressure
regulation and is unrelated to the observed behavior in this context. The fan's
operation is typically associated with cooling or ventilation and does not
influence the pump's differential pressure. On the other hand, if the pump is
overridden, it could lead to abnormal pressure readings, and if the static
pressure sensors are faulty, they could report incorrect differential pressures.
Therefore, the least likely cause for the current state is "Fan is overridden."
