Fault Finding
6.3.1 Lockouts/Blockings
Several checks are included to protect the boiler and its environment. High limit switch is constantly
monitored, safety times are constantly compared etc.
Any violation of (programmable) limits (and/or internal thermostat functions) will lead to an
error/fault or warning condition. The fan will not operate if there is a lockout or blocking condition.
6.3.1.1 Lock-out reset
Severe error will cause a lockout condition which can be cleared by pressing the reset button on the
control. In case of lockout and blocking conditions, Fan will not operate. Blocking error will be
resolved automatically if the cause of the error disappeared.
Error codes / Faults can be divided in two groups:
•
Lock-out condition codes
•
Blocking condition codes
Complete list of errors of the controller is given in the following table:
NOTE: The Error / Fault codes are visible only through a PC interface
ERROR
CODE
DESCRIPTION CAUSE AND POSSIBLE SOLUTION
LOCK-OUT ERRORS
01 Flame lockout
after several
ignition trials
Lockout signal after no flame and all ignition trials are expired. This error
condition is stopping the boiler from running. To get to the normal
operation again, manual/remote reset is required. By using the local
reset key, number of resets are not limited. However, all remote resets
(communication) are limited to 5 resets per hour.
02 False Flame
Indication Error is created if flame current is detected in illegal situations (no heat
demand currently present, gas valve closed, safety time passed). This
error condition requires manual reset action.
03 High Limit error High Limit error is created if the safety cut-off switch opens due to an
overheat situation in the application,
04 APS related Errors If the APS is configured and the APS does not open or close within the
configured time limits Error 4 is generated. If the APS is not configured
but an APS switch is detected on the input Error 4 is also generated.
05 Fan Tacho signal
error
If the measured fan speed is not within 900 RPM of the requested fan
speed in 20 seconds, error will be generated
08 Flame circuit error During normal operation of the ignition controller, flame circuit is
regularly checked. This check has predictable behaviour and several
steps. If check fails, error 8 will be set.
09 Gas valve driver
circuit error During normal operation of the ignition controller, valve drive circuit is
regularly checked. This check has predictable behaviour and several
steps. If check fails, error 9 will be set.
13 Remote reset
lockout (volatile) All remote resets (communication) are limited to 5 resets per hour. If the
limit is exceeded, Volatile lockout error is set; the error disappears after
power off/on the boiler.
21 ADC error
Internal controller error.
25 CRC error
Matching error on CRC codes (different software versions).
BLOCKING ERROR
34 Low Mains Voltage Low Mains voltage (less than 150 +/- 10 VAC) will trigger this error.
When Mains brought back (VAC), error is resolved in 10 seconds.
