Detailed Description
POC 2 switch output does not match valve seat 2
powered/not powered status.
Could be due to swapped internal SOLENOID 1/SOLENOID
2 connections or swapped internal POC 1/POC 2
connections. Can occur if valve electronics orientation is
swapped in field or electronics is replaced in field.
May also be due to failures of POC switch, solenoid or
electronics.
High gas pressure above threshold.
Pressure Module not configured for low and high gas
pressure functions.
Pressure out of allowed range.
Pressure Module communication fault or pressure
measurement reading error.
System pressure above Pressure Module rating.
Detailed Description
Factory Key storage is corrupt. Internal micro memory flash
corrupted or factory initial key installation missed. Field
recovery not possible.
Installer password is not configured (set to default value).
OEM password is not configured (set to default value).
Installer account is temporarily locked down due to too many
login attempts with wrong password.
OEM account is temporarily locked down due to too many
login attempts with wrong password.
Installer password reset feature is temporarily disabled due
to too many unsuccessful reset attempts.
OEM password reset feature is temporarily disabled due to
too many unsuccessful reset attempts.
OEM reset password is not configured although the feature
is enabled.
Solenoid 1 relay was detected closed during SSOV cycle
test.
MV1 terminal is not energized.
Possible internal valve electronics fault.
Solenoid 1 feedback not sensed at valve main electronics
while MV1 terminal is energized. Possible internal valve
electronics fault.
Solenoid 1 expected and detected mode do not match.
Solenoid 1 terminal signal is not valid. Frequency or duty is
out of expected range.
MV2 terminal is not energized.
Possible internal valve electronics fault.
Solenoid 2 feedback not sensed at valve main electronics
while MV2 terminal is energized.
Possible internal valve electronics fault.
Remediation Steps
Remove power and shut-off gas supply as necessary.
1.) Remove valve front electrical and rear solenoid enclosures.
2.) Inspect internal wiring between solenoids and valve electronics. The solenoid number is indicated by
the direction of flow arrow and number (2) in the valve casting. Ensure the appropriate solenoid connector
is placed in the appropriate terminal (SOLENOID 2) on the valve electronics assembly.
3.) Inspect internal wiring between solenoid proof of closure switch(es) and valve electronics. The
solenoid number is indicated by the direction of flow arrow and number (2) in the valve casting. Ensure
the appropriate solenoid proof of closure connector is placed in the appropriate terminal (POC 2) on the
valve electronics assembly.
4.) Replace cover and restore power and gas. Reset valve and burner management system, monitoring
for proper POC operation in conjunction with valve LEDs and burner management system inputs.
5.) If fault persists, replace valve main electronics.
6.) If fault persists, replace entire valve.
1.) Reset valve and burner management system, observing burner operation for proper pressures.
2.) Adjust appliance regulator as necessary.
3.) Recommission Low gas pressure setting as necessary.
1.) Reset valve and burner management system, observing burner operation for proper pressures.
2.) Adjust appliance regulator as necessary.
3.) Recommission High gas pressure setting as necessary.
NOTE: Low and High gas pressure settings must be configured before valve will be operational.
1.) Commission Low and High gas pressure settings as necessary.
1.) Verify the Pressure Module rating is correct for the application.
2.) If the pressure module is correct, reset valve and burner management system, observing burner
operation for proper pressures.
3.) Adjust appliance regulator as necessary.
4.) If inlet pressure is higher than Pressure Module rating, remove power and shut off gas supply and
replace Pressure Module with higher rated model.
Remove power and shut-off gas supply as necessary.
1.) Remove valve front electrical enclosure and verify the Pressure Module terminating connector is fully
inserted in the socket labeled 'PRESSURE' in the electrical enclosure.
2.) Check for a nearby source of strong electro-magnetic interference. Reset valve and burner
management system when corrected.
3.) Remove Pressure Module from valve body.
4.) Inspect the O-ring provided on the Pressure Module to ensure that it is clean and fully seated in its
oval groove.
5.) Verify the Pressure Module is correctly seated on the valve body locating posts, is flush against the
valve casting and the O-ring is compressed.
6.) Verify the correct mounting location and pressure port are being used for the valve model - refer to
documents 32-00017 and 32-00029.
7.) Recommission Low and High gas pressure settings as necessary.
1.) Verify the Pressure Module rating is correct for the application.
2.) If the Pressure Module rating is correct, reset valve and burner management system, observing burner
operation for proper pressures.
3.) Adjust appliance regulator as necessary.
4.) Recommission Low and High gas pressure settings as necessary.
5.) Test Low and High gas pressure trip points as necessary.
Remediation Steps
6.) If inlet pressure is higher than Pressure Module rating, remove power and shut off gas supply and
replace Pressure Module with higher rated version.
Replace valve main electronics board.
