9.1 High Pressure
Pressure exceeds the pressure setpoint
POSSIBLE CAUSE
POSSIBLE SOLUTIONS
Closed discharge isolation valve
Pressure transmitter incorrectly scaled -
Or, the high-pressure switch* is set incorrectly
Incorrect fault settings
Defective sensor wiring
Defective transmitter
Open the discharge isolation valve completely.
• Pressure Transmitter: correct the scaling value on the controller HMI.
• High Pressure Switch: manually adjust the high-pressure switch setting.
Adjust High Pressure Fault setting.
Repair or replace sensor wiring.
Compare pressure transmitter data (via HMI) with the discharge pressure gauge.
A significant difference between readings indicates either an incorrectly scaled, or
failed pressure transmitter.
The replacement pressure transmitter must have an appropriately scaled 4-20mA
output signal.
