DATASHEET AES D2M

The exhaust air and gas extraction control system AES-D is designed in
connection with the control unit AES-ST3.2 for the operation of one
stage fans in DIRECT SWITCHING (D) for the ventilation in normal
operation and for emergency smoke extraction.
The functionality of the control system corresponds to VDMA 24177.
The main switch, which can be shut off, is horizontally placed on the
outside of the control unit. It can be used as an emergency-off switch if
the control unit is attached in visual proximity to the fan motor. The main
switch can also be locked in the On position or sealed to prevent
unintentional shut-down of the system.
On the front of the operating and display module, the ventilation system
can only be switched to SMOKE EXTRACTION or READY mode or to
ON. OFF switching is not possible. The operating conditions are
displayed optically. The overcurrent triggering must be unlocked on the
motor protection device after the disturbance is eliminated.
When air is being exhausted, all motor protection devices are
functioning to prevent motor damage.
During smoke extraction, all motor protection devices are bypassed so
that the longest possible function duration can be achieved before the
fan motor is destroyed.
The AES switching device should be installed as closely as possible to
the associated fan outside of the area from which smoke is to be
extracted and be accessible via escape and rescue routes.
The power supply for smoke extraction fans must be connected
directly on the NSHV and designed to maintain function.
In the case of smoke extraction, fan motors may not be operated by
frequency converters or similar control devices.
Observe the permissible motor switch-on speed / h when starting up
in smoke extraction mode. Otherwise the fan motor can be destroyed
due to the bypassed motor protection devices!
Smoke extraction systems must undergo a complete function check
every 3 months and be serviced once a year.
Project-related smoke extraction switching systems, special switches,
emergency power supply on request.
