Design with actuating mechanism
■
Belimo actuators are used for dampers, series BEN, BEE,
BE for 230V AC resp. 24 V AC/DC, Schischek InMax 50.75-S
actuators (universal 24V or 230V supply) are used for
large size of dampers.
■
After connection to the power supply voltage, the
actuator moves the damper blade to the "OPEN" position
or "CLOSED" (according to the corresponding connection,
see wiring diagram). If the power supply is interrupted,
the actuator stops at the current position. The signalling
of the "OPEN" and "CLOSED" damper blade positions is
ensured by two built-in fixed “potential-free” end- limit
switches.
■
The actuator for operating the damper blade is mounted
in an insulated cover/box. It is accessible after removing
the cover lid. The electrical connection of the actuator is
made with a non-flammable cable (or a cable located in
the adjoining cable duct), which passes through an
opening made in the wall of the insulated cover/box when
installing the damper or when connecting the actuator
power cable. The power and control cable must be CAT 3
as BS EN8519.

■
Belimo modulating actuators, BEN (BEE)-SR series for 24V
AC/DC are specially designed for remote control of fire
dampers. The position of the damper blade is adjustable
by means of control voltage 0 (2)...10V DC.
■
The signalling of the "OPEN" and "CLOSED" damper blade
positions is ensured by two built-in fixed “potential-free”
limit switches.
