Ventilation and Smoke Extraction Control Unit AES-ST3.2
The ventilation and smoke extraction control unit AES-ST3.2 is designed for the
operation of one or two-stage fan motors for ventilation under normal operating
conditions and for emergency smoke extraction. The control unit is 12101 / Part 9
designed in accordance with DIN EN and has a general TÜV certificate.
The functionality of the controller corresponds to VDMA 24177 and the BHE guidelines
for mechanical smoke extraction system.
When bleeding all motor protection are organs in function.
With smoke extraction are all motor protection devices to achieve the longest possible
Longevity bridged to the destruction of the fan motor.
Operation + Display module (internal)
READY Ventilation is switched off. The READY indicator is lit.
An external smoke extraction alarm activates the smoke extraction mode as described in
SMOKE EXTRACTION. In this switch position the fan motor can also be switched on in
ventilation mode by a connected REMOTE SWITCH as described in ON or
ST.1/ST.2.
SMOKE EXTRACTION Ventilation flap drives to OPEN position. In smoke
extraction mode the fan motor is switched to a high speed via the start-up circuit. The
SMOKE EXTRACTION indicator is lit. The motor circuit breaker is disabled. The fan can
only be switched off by resetting the triggering alarm or by the external FIRE BRIGADE
switch.
ON or ST.1 / ST.2 Ventilation flap drives to OPEN position. In ventilation
mode the fan motor is switched on at the selected speed. The OPERATING indicator is lit.
The motor circuit breaker is enabled. An external smoke extraction alarm activates the
smoke extraction mode as described in SMOKE EXTRACTION.
INTERFERENCE Indication that the motor protective device, the repair
switch has tripped or a system fault. In ventilation mode the fan motor off. In smoke
extraction of the fan motor is not switched off. The Message needs to Troubleshooting the
motor protective device and on the controller AES ST3.2 be unlocked.
FIRE BRIGADE SWITCH (external)
The switch has absolute priority. All other control elements are subordinated. It
up to 6 firefighters switch (FWS-P4 / FWS-4S) are operated equally. About LED signal
lights of the plant status is displayed. The detection loop is monitored for open and short
circuit.
On It is the smoke extraction triggered
OFF The system is independent of the previous mode Switched off. The fan motor
is no longer energized and the flap is fed in.
Motor circuit breaker (internal)
To monitor the motor rated currents for each fan level, various Motor protection devices
are connected. Alternatively, a monitoring (PTC) without additional equipment. When
triggered, a message is sent. The Message must be on the AES-ST3.2 reset. The fan
shutdown after Tripping occurs only in ventilation mode.
Fan enable (external)
If the ventilation in ventilation or smoke extraction is switched operation, carried out the
In-circuit the associated exhaust flap. Only when the flap over a Limit switch (NC) ON
signals, the fan is enabled for switching. In order ensures that the ventilation is not
working against the closed vent flap. Is no release contact connected, switch flap and
ventilation simultaneously.
Application
Function
Remote switching (external)
The remote switch can be connected as an additional switch for ventilation mode
and is subordinate to the OPERATING & DISPLAY MODULE.
0 or OFF Ventilation is switched off.
ON or ST.1 / ST.2 Ventilation flap drives to OPEN position. In ventilation mode the
fan motor is switched on at the selected speed. The OPERATING indicator is lit.
The motor circuit breaker is enabled. Smoke extraction mode is activated if an
external smoke extraction request is received.
Flap actuation (external)
If the ventilation is switched on in ventilation or smoke extraction mode, the
associated ventilation flap is actuated. For maximum functional reliability the flap
output is fed via a separate fuse.
Operating / Ready / Smoke extraction / Overload (signal)
Non-isolated (+ 24VDC) relating to the forwarding of a parent body.
ARM - automatic smoke alarm (external)
For connection of up to 20 automatic smoke detectors. When is detector alarm
smoke extraction triggered. The detection loop is a short circuit, wire break and
missing alarm insert monitored. The alarm is latching. The reset of the alarm via
the "System Reset", or by pressing the reset button on the manual call HRM-3 for 1
second.
BMZ - central fire alarm (external)
In Message triggering by the BMZ or interruption of the connecting line is
triggered smoke extraction. The detection loop is on Short monitored. The release
is optionally storing or self-resetting. To be set using selector switch on the control
part.
HRM - manual smoke vent button (external)
For the connection of up to 20 manual call points, in execution as smoke vent
button or alternatively connected as manual call points in-stage version over
Opener will. The setting is made via the selector switch on the control unit. In
detectors operating is triggered smoke extraction and stored the alarm.
Selector switch in position "DKT" (tripping: 20mA current signal)
The detection loop is monitored for open and short circuit. A Resetting the alarm
can be made directly at the smoke vent button.
Selector switch in position "DKM" (triggering: NC / wire break)
The detection loop is monitored for short circuits. Resetting the alarm
carried out by previous provision at the tripped detectors and hand
subsequent resetting by "System Reset".
INTERFERENCE / Warning (signal)
Isolated signal contact system disorder.
Possible causes: power supply is missing or main switch off control Blown fuse,
low voltage supply is broken, triggered motor monitoring, fault the detector loops,
repair switch.
Triggering ventilation (internal)
Switching outputs for switching on the fan stages 1 or 2 in accordance with the
Request by external detector / controller.
Analog output 0-10V (internal)
For two ventilation levels and for the smoke extraction operation, the signal level
be set separately on the AES-ST3.2.
Repair switch - Signal input (external)
In ventilation mode is performed fan shutdown and fault.
In smoke extraction operation only fault occurs, no Fan Off!
The repair switch must always be carried out with load disconnect.
LT - lamp test (internal)
Control input for controlling the indicator lights on the control and display module.
Optical on-board diagnostics (internal)
For quick and easy diagnosis of system status on the Controller AES ST3.2
visually.
Operating mode (ready, tripped and fault)
Per detector loop, whether this has been triggered or a fault.
Fault to repair switch and the motor protective device
System-reset (internal: Button)/(external: Input Kl.60:61)
For central resetting the controller to the standby mode, after withdrawal of
allowances to the individual detector loops.
Lock function(external control input +24VDC)
Work several AES ST3.2 on only one common smoke extract fan, provides the
barrier function provides a possibility that only a control part always active can be.
With Lock function is active, the controller is disabled, this included also the
fireman's switch. There is fault / alarm is generated.
