The first or top line of the message is not custom and is the same as the top line in the standard lockout message. This
line permits the user to navigate to the Lockout Detail page.
The lockout message (standard or custom) displays continuously while the lockout condition persists. The user may elect
to exit the message to view other pages by pressing the “Left arrow” or “Home” button which navigates to the Home page.
The lockout condition is displayed on the Home page (see Fig. 27) which permits the user to re-display the lockout
message. Pressing the “Right arrow” button when the lockout fault code line has input focus causes the lockout message
to be re-displayed.

Table 5. Fault Message Summary.
Fault Code System Failure Recommended Troubleshooting
Fault 1
*No Purge Card*
No card is plugged into the
purge card slot.
1. Make sure the purge card is seated properly.
2. Inspect the purge card and connector on the relay module
for damage or contaminants.
3. Reset and sequence the relay module.
4. If the fault code reappears, replace the purge card.
5. Reset and sequence the relay module.
6. If the fault persists, replace the relay module.
Fault 2
*AC Frequen/Noise
Excess noise or device
running on slow ac.
1. Check the relay module and display module connections.
2. Reset and sequence the relay module.
3. Check the relay module power supply and make sure that
both frequency and voltage meed the specifications.
4. Check the backup power supply, as appropriate.
Fault 3
*AC Line Dropout
Ac line dropout detected.
Fault 4
*AC Frequency*
Device running on fast ac.
Fault 5
*Low Line Voltage*
Low ac line detected.
Fault 6
*Purge Card Error*
Purge card timing changed
since card was initially read.
1. Make sure the purge card is seated properly.
2. Inspect the purge card and connector on the relay module

*Flame Amplifier*
Flame sensed when flame not
present.
1. Check wiring and correct any errors. Make sure that the
flame sensor wires are in separate conduits. Check for
noise coupling into the flame detector leadwires.
2. Make sure that flame detector and flame amplifier are
compatible.
3. Remove the flame amplifier and inspect connections.
Reset the flame amplifier.
4. Reset and sequence the relay module.
5. If the code reappears, replace the amplifier.
6. If the fault persists, replace the flame detector.
7.
If the fault persists, replace the relay module.
