Application
The type LMC24(-S) is intended for the
operation of air control dampers in venti-
lation and air-conditioning systems.
Mode of operation
Open/Close control by single-wire or
2-wire system.
Product features
Simple direct mounting on the damper
spindle by universal spindle clamp. An
antirotation device is supplied to prevent
unwanted rotation of the whole unit.
Manual operation by self-resetting push-
button
when necessary (the gearing is
disengaged while the pushbutton is held
depressed).
Adjustable angle of rotation with me-
chanical stops.
High functional reliability
The actuator is overload-proof, needs no
limit switches and halts automatically at
the end stops.
Flexible signalling 0…100%, with adjust-
able auxiliary switch (LMC24-S only).
