Belimo
Operation
Damper is delivered in closed position. When
electric actuator is connected to the power
supply damper will open. When the damper
reaches the end position (damper open), in
which is it blocked, the electromotor will stop.
Closing fire damper takes place automati¬cally
when a power failure occurs. Thermal tripping
device that comes with fire damper causes
power circuit break at a temperature of 72 °C
(inside or outside duct). If checking is needed
for proper functioning of fire damper, pushing
the switch on the thermal tripping device will
close damper. When switch on tripping device
is released, the damper will open.
Damper can be opened without connecting
to a voltage with enclosed handle turning in
the direction of the arrow on electric actua -
tor (clockwise). Damper can be locked in the
desired position by fast turning back handle
a quarter of a turn (counterclockwise) for Be-
limo BF, and by puling brake on Belimo BFL
and BFN.
To unlock the electromotor, turn handle clock -
wise for a quarter of a turn for Belimo BF, or
release brake for Belimo BFL and BFN. After re -
lease, damper will be closed by return spring.
When damper is opened manually, electric
actuator will not move the damper into closed
position after power failure (ther¬moelectric
fuse).
