4 Design and Functions
4.9 Actuator
4.9.1 Operation after Power ON/Long RESET
The actuators have internal position feedback using an incremental encoder. For the automat-
ic adjustment of the position detection, the actuators move to the reference mark set in param-
eters P 455 - P 457. The actuators carry out a transposition test, if activated by P 461. After
passing this test the actuators move to position for the closed damper.
4.9.2 Direction of Rotation/Position Damper Closed
For actuator 662R550... (0.8 Nm) direction of rotation of factory setting is clockwise in quad-
rant from 12 o'clock to 3 o'clock position (P 458 - P 460/channel 1 - channel 3). Adjust ’closed
damper’ position between 12 o’clock and 3 o’clock position as follows:
•
12 o’clock position

P 458 - P 460 = 0
• 3 o’clock position

P 458 - P 460 = 1
For actuator 662R5001...(1,2 Nm), 662R5003...(3 Nm) and 662R5009... (9 Nm) direction of
rotation of factory setting is counter-clockwise in quadrant from the 12 o'clock to 9 o'clock po-
sition (P 458 - P 460/channel 1 - channel 3). Adjust ’closed damper’ position between 12
o’clock and 9 o’clock position as follows:
•
12 o’clock position

P 458 - P 460 = 0
• 9 o’clock position

P 458 - P 460 = 1
4.9.3 Detection of Actuators with Mixed-up Connections
While replacing BT300 make sure actuators are re-connected to the correct channel. Label
the plugs/cables to prevent faults or use the ’transposition test’ in BT300 (parameter 461 = 1).
Automatic transposition detection according to this principle is not possible if channel 1 or
channel 2 are moved to 9 o'clock position (662 R 550...) or 3 o'clock position (662R550...) for
referencing.
To detect transposition of actuators you must implement certain features into burner design.
•
The actuator on channel 1 requires a mechanical stop at an angle of 94° (+- 2°).
• The actuator on channel 2 requires a mechanical stop at an angle of 104° (+- 2°).
• The actuator on channel 3 does not need a mechanical stop.
After a long RESET (e.g. after BT300 is switched on), all actuators automatically align position
detection.
Next, channel 1 will not be moved, channel 2 moves on 99° further from 12 o'clock position
and channel 3 moves 108.5° in a clockwise direction.
If actuators are connected to correct channel, none of the actuators will be blocked.
If two actuators are transposed, one of the actuators is blocked and therefore does not reach
its target position. This leads to an error message, and a burner start-up is prevented.
In versions 3.7.0.0. and 3.8.0.0., the detection of inverse connected actuators and referencing
at the 3 o'clock / 9 o'clock position cannot be selected.
From version 3.9.0.0. on, the detection of inverse connected actuators and referencing of
channel 3 at the 3 o'clock / 9 o'clock position can be selected.
