Operation
Floating control
Commands the actuator to extend
or retract using the proprietary
Siemens FHC/LRC pulsed control
signal or industry standard 3-
position pulsed signals.
0-10Vdc/4-20mA
0-10Vdc or 4-20mA control signal
controls the damper actuator. The
actuator stroke is proportional to
the control signal.
Power failure
Either maintain current position or
fail NO/NC. User selects the
appropriate failsafe position for
application.
Wiring
All wiring must conform to NEC and
local codes and regulations.
