Table 7: Error code table
During the time the cause of fault is diagnosed, the control outputs are dead.
Burner remains shut down
-
External fault indication remains deactivated
-
Fault status signal (alarm) at terminal 10, according to the error code table
-
The diagnostics of the cause of fault is quit and the burner switched on again by resetting
the burner control. Press the lockout reset button for about 1 second (<3 seconds).
Note!
When using coiled igniters, flame detection may be improved by increasing
parameter 228 (tfz). To prevent an extended safety time (TSA, parameter 227) in that
case, the postignition time (t3n, parameter 257) must be reduced to the same extent.
Warning!
If the set safety time (TSA) is too long, the safety functions will become
ineffective. Compliance with the relevant standards must be ensured!
