1.1 Validity of these Instructions
This document is a supplement to the Operating Instructions for the appliances listed below.
It is only applicable together with the Operating Instructions for the affected device.
The specifications in this document refer to the software version BT300 v3.9 and UI300 v3.11
/ v4.2 and higher. The following functionalities are not available with software versions <3.0 of
BurnerTronic.
• CO/O

The designation UI300 used in the document applies to UI300-LSB, UI300-V1 and UI300-V2.
This document is applicable for the following devices:
1.2 Faults
NOTICE
The LAMTEC burner controls use different methods to detect fault messages between main
processor and watchdog processor:
BT300/ETAMATIC/FMS/VMS/FA1:
The bus transmission does not generally use different fault numbers to distinguish between
watchdog processor and main processor faults. In order to distinguish the main processor fault
messages from the watchdog processor fault messages, an offset of 10000 is added to the
watchdog processor faults. The main processor fault message H002 becomes the watchdog
processor fault message U10002.
CMS:
CMS allocates different fault numbers to main processor and watchdog processor faults.
An offset is not necessary.

manually and reset the fault.

802 1 1 Integration of a channel into the electronic ratio control needs
too much time.
Channel
This fault only affects the recirculation channel.
Possible causes:
Recirculation valve is sluggish or blocked.
The physical path of the damper is too long.
– When switching on the recirculation damper, run the
recirculation channel with a lower burner firing rate.
– Adjust curve
803 0 0 Channel is out of 1st monitoring band for too long. Channel
– Check the damper for ease of movement.
In case of sluggish operation, clean the damper and make
it run smoothly again.
– Check the function of the servomotor without damper and
replace if necessary.
– For analogue output (VSM), check the ramp speed of the
frequency inverter and adjust it if necessary.
– Adjust the positioning speed in P 453 (reduce value).
Note:
Fault will be fixed with software version 3.9

The fault is due to a channel which is not deactivated or con-
trolled by the electronic ratio control (i.e. in pre-purge or post-
purge).
The fault occurs during an internal self-test.

Cause of
VSM100
fault
Possible cause of error :
– Connection between VSM/LCM GND and protective
earth PE is defective.
– Feedback of the speed variation was too fast
– Fault of VSM
– Fault on the LSB (red LED flashes or is permanently ON)
D1:
185 = VSM100
D2:
0 = Unknown cause
1 = Fault in FlashCRC
2 = DIP switch is inconsistent for input selection
(Namur/3-wire/current, the high byte contains the DIP
switch position).
3 = Like 2, but with a different code position
4 = Like 2, but with a different code position
5 = SRAM fault, high byte contains the code position
6 = Stack error
7 = Fault in CPU self test
8 = RAM error
9 = Delta-T-error. Fixed with VSM version 1.2.0.0.
10 = Fault in reference voltage, the upper 12 bits contain the
values of the reference voltage.
11 = Other fault/crash
12 = PowerOn, the device was shut OFF

889 0 0 The time gap between two remote fault resets is too short.
EN 14459 allows only 4 remote fault resets every 15 min.
The fault reset is monitored by LSB Remote Software, UI300,
LAMTEC SYSTEM BUS and field bus. Exceeding the num-
ber of fault resets causes the fault shot-down 889 and further
remote fault resets are ignored. After a delay time another
remote fault reset is possible.
The fault shut-down H889 also occurs, if a fault reset is sent
without any reason.
A reset by terminal is always possible.
How to reset this fault:
– Wait for 15 minutes until you try to reset the fault again.
– Cut off the power supply from BT300 for an instant,
reconnect it and reset the fault subsequently.

985 0 0 VSM diagnosis fault
Possible cause of the fault:
BurnerTronic expects a VSM module but the exchange of
diagnosis data with the module fails.
– A restart is required.
– Check wiring of the LSB
– Replace VSM

– Check the damper for ease of movement.
If sluggish, clean the damper and make it run smoothly
again.
– Check servomotor function without damper and replace if
necessary.
– For analogue output (VSM), check ramp speed of the
frequency inverter and adjust if necessary.
– Adjust the positioning speed in P 453 (reduce value).
– Reset fault and switch mains voltage off and on again.
