Appendix A - Troubleshooting And Hold/Lockout Code

To support the recommended troubleshooting, the Honeywell Sola Controller has a History File. Review the alert history for possible
trends that may have been occurring prior to the actual Lockout.
Alert code and Hold/Lockout code can be accessed through Basic Panel, Enhanced or System Operator Interface Panel.
For instruction on accessing Alert and Hold/Lockout code using Basic Panel display, refer to CHAPTER 3-6 DIAGNOSTIC MODE for
more information.
For instruction on accessing Alert and Hold/Lockout code using Enhanced or System Operator Interface display, refer to CHAPTER 4-
11 FAULT/ALARM HANDLING for more information.
Code: H= Hold message; L=Lockout message
Code Description
1 Unconfigured safety data
2 Waiting for safety data verification
3 Internal fault: Hardware fault
4 Internal fault: Safety Relay key feedback error
5 Internal fault: Unstable power (DCDC) output
6 Internal fault: Invalid processor clock
7 Internal fault: Safety relay drive error
8 Internal fault: Zero crossing not detected
9 Internal fault: Flame bias out of range
10 Internal fault: Invalid Burner control state
11 Internal fault: Invalid Burner control state flag
12 Internal fault: Safety relay drive cap short
13 Internal fault: PII shorted to ILK
14 Internal fault: HFS shorted to LCI
15 Internal fault: Safety relay test failed due to
feedback ON
16 Internal fault: Safety relay test failed due to
safety relay OFF
17 Internal fault: Safety relay test failed due to
safety relay not OFF
18 Internal fault: Safety relay test failed due to
feedback not ON
19 Internal fault: Safety RAM write
20 Internal fault: Flame ripple and overflow
21 Internal fault: Flame number of sample
mismatch
22 Internal fault: Flame bias out of range
23 Internal fault: Bias changed since heating cycle
starts
24 Internal fault: Spark voltage stuck low or high
25 Internal fault: Spark voltage changed too much
during flame sensing time
26 Internal fault: Static flame ripple
27 Internal fault: Flame rod shorted to ground
detected
28 Internal fault: A/D linearity test fails
29 Internal fault: Flame bias cannot be set in
range
30 Internal fault: Flame bias shorted to adjacent
pin
31 Internal fault: SLO electronics unknown error
32-46 Internal fault: SaHfety Key 0 through 14
47 Flame Rod to ground leakage
48 Static flame (not flickering)
49 24VAC voltage low/high
Recommended Troubleshooting of Lockout Codes
1. New Device, complete device configuration and safety
verification.
2. If fault repeats, consult factory.
1. Device in Configuration mode and safety parameters need
verification and a device needs reset to complete verification.
2. Configuration ended without verification, re enter
configuration, verify safety parameters and reset device to
complete verification.
3. If fault repeats, consult factory.
Internal fault
1. Reset module.
2. If fault repeats, consult factory.
1. Check the Module and display connections.
