9-4. Fault Conditions

A fault condition occurs if the system encounters an isolation fault, encounters operating conditions outside operational limits, or if there is a serious

problem with the system. Should a fault condition occur, the output is immediately turned off, the red Fault LED flashes and the Stop

button

LED flashes. If the active screen on the LCD display is Run Status or Parameters, a message describing the particular fault condition will appear on the

display. If the active screen is Program, press the Run Status

button to display the fault condition.

Pressing the Decrease

button will acknowledge the fault and the red Fault LED will stop flashing and remain on continuously. However, the

Stop

button LED will continue to flash indicating that the process has stopped.

To obtain additional information regarding the fault condition and suggested solutions to resolve the fault, press the Increase

button, and the

LCD display will indicate possible solutions based on the type of fault condition. In most cases, a fault condition will indicate that service is required.
