Art. no.: 77039
Application
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.
Function
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.
Notes
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.
