DATASHEET AES SD

The exhaust air + smoke extraction control system AES-SD is designed in
connection with the control unit AES-ST3.2 for the operation of one-stage fans in
STAR-DELTA SWITCHING (SD) for ventilating 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.
The fan motor is to minimize the stress on-site Power always switched on star-
delta.
The star-delta starting time is adjustable.
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.
