Recommended measures or causes
Define burner identification and repeat backup
Repeat reset and backup
Repeat reset and backup
Repeat reset and backup
Make a reset, check the connections and repeat the backup
Refer to User Documentation Modbus (A7541)
TÜV test may only be started in phase 60 (operation)
TÜV test default output must be lower than the lower output limit
TÜV test default output must be higher than the upper output limit
No error: Manual abortion of TÜV test by the user
No loss of flame after fuel valves have been shut
1. Check for extraneous light
2. Check wiring for short-circuit
3. Check to see if one of the valves is leaking
1. Check wiring of analog trim specification to see if there is an open-circuit / loose contact
2. Check the process date of the read-in trim specification
(parameter 916; 4 mA = -15% / 12 mA = 0% / 20 mA = 15%)
The curve setting of the VSD / PWM fan must include a reserve for the set trim range.
((Minimum value curve + negative trim range)  curve point  (maximum value curve -
positive trim range))
The curvepoint of the VSD curve is below the permissible minimum value
(diagnostic code = curvepoint number; e.g. 1 = P1)
The curvepoint of the VSD curve is above the permissible maximum value
(diagnostic code = curvepoint number; e.g. 21 = P1)
Fuel 1: The curvepoint of the VSD curve is below the permissible minimum value
(diagnostic code = curvepoint number; e.g. 41 = P1)
Fuel 1: The curvepoint of the VSD curve is above the permissible maximum value
(diagnostic code = curvepoint number; e.g. 61 = P1)
Warning message!
Trim function is in limitation for too long (parameter 535; 916 < 531 or 916 >
532).This can be an indication that the trim function or the VSD curve is set
