The group control module GS 9 is used to contr
ol drives.
The signals iss
ued by the smoke and heat exhaust ventilation
bus
6
are given the highest priority. The signals issued by
the ventilation bus
5
are given the second highest priority.
The signals issued by the ventilation pushbutton bus
7
are
given the lowest priority.
If an SHEV OPEN command is given, the motor output will
be switched to OPEN again every 2 minutes for a duration of
30 minutes.
The motors are connected to a 3-pin plug-in terminal
1
.
The terminal 3 of this plug-in terminal is intended to monitor for
cable break and trigger an EMERGENCY STOP.
The motor output is protected by a fuse which is integrated into
the guard circuit.
Cable break in the area of the motor lines and EMERGENCY
STOP operation is indicated by a yellow LED
8
(which flashes
during emergency stop operation).
A potentiometer
3
can be used to change the operating mode
of the module:
- When the potentiometer is set to zero, the operating mode of
the ventilation pushbutton is “OPEN-STOP-CLOSE”,
- A different potentiometer position means operating mode
“OPEN-CLOSE”.
The set voltage value determines the time during which the
drives will be moving towards the “OPEN” position. The STOP
button is without function when the timer is switched on. The
running period does not interfere with the smoke and heat
exhaust ventilation functionality.
The running period voltage is measured at the contacts
9
.
The voltage values are assigned to the following running
periods in “ON” direction:
To ensure observance of guideline ZH1/494, install EMERGEN-
CY STOP pushbuttons on windows that are less than 2.5 m in
height. The design of these EMERGENCY STOP pushbuttons
must comply with standard DIN EN 60204.
The devices used to protect against crushing hazards and the
EMERGENCY STOP button used as an “opener” are connect-
ed in series and integrated into the motor guard circuit (see
drawing). When combined with the GS 9 module, they provide
the following functions:
- If the direction in the module is switched to “OPEN”, the
disruption of line 3 is only defined as a “malfunction” in the
central control unit.
- If the direction “CLOSE” is switched as a ventilation function
(includes ventilation pushbutton, superordinate ventilation,
wind/rain sensor, delayed smoke and heat exhaust venti-
lation reset) and wire 3 is interrupted (equal to actuation of
EMERGENCY STOP pushbutton), the GS 9 module will trigger
an internal malfunction. The drives in this group will be stopped,
while the internal malfunction remains active and is indicated
in the fire pushbutton as well as on the module. Actuating
the module in “OPEN” direction will reset the error message
mentioned above and allow the drive to move again during the
next “CLOSE” operation.
Pressing and holding the “Reset” button in the fire pushbutton
will disable the EMERGENCY STOP functi
on.
Releasing the reset button will enable the EMERGENCY
FUNCTION again.
If a connected timer is switched on, the ventilation function
will be blocked after an emergency stop has been triggered.
Pressing the reset button in the fire pushbutton or on the RWA
9 module of the central control unit will enable the ventilation
function again.
An additional reset button is installed on the smoke and heat
exhaust ventilation bus of the group module in the central
ventilation units LZ 9 to reset the EMERGENCY STOP function
manually (see drawing below). In the event of an EMERGENCY
STOP, the control unit must be reset by issuing an “OPEN” or a
reset command (in combination with a timer).
