Faults - Probable causes - Solutions
241 0 0 Actuator does not move, i.e. no position feedback. Channel
Direction:
P 2 =
backward,
forward
If this indication is shown, the monitoring of fault 271 is damaged.
251 0 0 Actuator cannot find reference position Channel
Direction:
0 backward
1 forward
Check the flap's smooth-running to reference position.
261 Unlimited 3
Actuator returns invalid position (difference to target position too
large)
Channel
271 Unlimited 3
Actuator feedback remains constantly for too long, even when ac-
tuator has moved
Channel
281 1 1 Feedback signal of at least 1 actuator is incorrect Channel
To identify the actuator’s direction of rotation two pulse form sig-
nals, offset 90 degrees, are returned by the actuator.
If fault 281 occurs, these signals are not identified correctly.
Cause of error:
–
back lash
– actuator 0,8 Nm: external torque clockwise >0.2 Nm
– actuator 9 Nm: external torque clockwise >1 Nm
291 Optional 3
Actuator does not reach the final position, because of mixed- up de-
tection.
Channel
Actuators are mixed up while reconnecting. The test for recognising
this fault is described in the manual of the BT300 - print no.
DLT1201.
At least one actuator does not reach it's test position:
–
2 actuators are mixed up
– another problem inhibits the actuator to reach it's test position
320 1 1 Open broken wire at firing rate input
321 1 1 Open broken wire at feedback channel: channel Channel
351 1 1 Invalid fuel change while burner is running
352 Optional 3 Invalid combination of fuel signals (no signals)
353 Optional 3 Invalid combination of fuel signals (several signals)
