Practical Commissioning Case

During startup of a refinery utility system, twelve solenoid valves controlled by an ADV569 module failed to operate after commissioning.

Controller diagnostics showed normal communication, and voltage at the module terminals measured approximately 24 VDC. However, field measurements at the valve terminals indicated significant voltage loss.

Engineers discovered an incorrectly terminated common negative conductor affecting one 16-channel output group.

After correcting the wiring:

• All affected outputs responded normally.
• Field voltage recovered to nominal values.
• No hardware replacement was necessary.
• The system completed commissioning successfully.
