12 Actuators X53 / X54
One or 2 actuators can be connected to the LMV36... system, depending on the
selected operating mode (refer to chapter
Selection of operating mode
).
Caution!
When mounting the actuators, it must be made certain that the mechanical link
to the controlling elements is form-fitted!

Figure 77: Fuel actuator (X54)
When using 2 fuel actuators for each type of fuel, they must be connected to the
AGM60... switch unit (refer to chapter
AGM60...
). Otherwise, the fuel actuator must be
connected directly to the LMV36...

12.1 Function principle
The actuators are driven by stepper motors. The resolution reached when making 1
positioning step is 0.1°.
The running speed of the actuators is fixed at 5 seconds for a positioning angle of 90°
for SQM33.4, SQM33.5, and SQN1.
The speed is 10 seconds for a positioning angle of 90° for SQM33.6.
The SQM33.7 requires 17 seconds for a positioning angle of 90°. An optical incremental
transducer is used to monitor the current position. Due to the use of a gear train with
almost no backlash, position control is not required.
12.2 Definition of angles
The angles and angular ranges are specified in the Data Sheets of the relevant
actuators.
SQM33.4…: Refer to Data Sheet N7813
SQN1…: Refer to Data Sheet N7803
