SV2 Series Safety Shut-off Valves
VALVE FAULT CODES
There are several possible fault conditions, some of which are dependent on the valve configuration ordered and installed
accessories. The HMI and PC Tools provide detailed fault code descriptions and remediation steps for the operator to follow to
rectify any fault condition. The information in this section details all of the possible fault codes and their remediation steps.
NOTE: Upon valve reset after a fault, the software will not allow the valve seats to be re-powered by the burner control for 7
seconds to accommodate various flame failure response timings.
