What does it mean when the Nordson EFD Controller displays 'System Alarm: Heater Fault'?
A 'System Alarm: Heater Fault' indicates a failed heater or shorted RTD in the valve. To address this, switch off the controller, wait 5 seconds for the valve to fully discharge, and then switch it back on. If the alarm persists, refer to the troubleshooting section of the valve manual. If the Heater Fault alarm continues, contact Nordson EFD.
