Setting unit AST10 5851
The VAV compact controller GDB181.1E/3or GLB181.1E/3can be used with or without
an internal VAV/CAV controller.
The following parameter are available in the unit:

1) If the function type "3pt+sensor" has been selected for the VAV compact controller, a value can be
set, but does not have any influence
The setting of parameters "Motor direction" and "Address" (only in connection with
DESIGORX...) is made at the DIL switches.
Adjustment of all other parameters occurs by means of the setting unit AST10via
terminal UC with digital communication.
The VAV controllers GDB181.1E/3or GLB181.1E/3together with the RCE84.21forms
a room temperature cascade controller with the room temperature as the main control
variable and with the air volume as the auxiliary control variable.
In this control type, the deviation of the room temperature defines the setpoint for the air
volume. The air volume is then kept at this setpoint by the auxiliary control, i.e., the
pressure fluctuations in the duct, which appear as a fault variable, have no influence on
the air volume and thus no influence on the room temperature.
The control response for the "Air volume" auxiliary variable is P (proportional).
The air volume actual value in the air duct is acquired via the differential pressure p by
means of a membrane pressure sensor. The differential pressure is converted
electronically to an air volume signal, which is made available at terminal UC (core 9) as
a DC 0...10 V output signal (e.g. for air volume indication).

otherwise, the contrary applies
The DC 010 V signal at terminal Y serves as the setpoint for the air cascade control
loop. The setpoint, in dependence of the pressure situation in the supply air duct and
within the limits of maxV and minV , determines the required air volume.
Depending on the input switch setting (open/close) of inputs Y1 and Y2, control occurs
to the desired CAV value. With an open input, the GDB181.1E/3or GLB181.1E/3
controls to minV , and with a closed input to maxV .
With the aid of parameter Vn , the measuring range of the GDB181.1E/3or
GLB181.1E/3can be adjusted at the factory (box manufacturer) to the respective
nominal volume of the unit for the air boxes. This ensures that the maximum permissible
nominal volume of the unit is not exceeded.
100 % nominal air volume of the air box then corresponds to DC 10 V of the measuring
range of the GDB181.1E/3or GLB181.1E/3. This setting can be checked at terminal
UC.
With the aid of the setting parameters minV and maxV , the air volume can be limited by a
minimum and maximum air volume.
With supply/extract air control, a room over- or underpressure up to 20 % max. at equal
duct cross sections and pressure ranges with the aid of parameters maxV and minV of
the cascade controller.
For supply and extract air control, parameters maxV and minV allow for duct
compensation of max. 20 %.
By switching signal inputs Y1 and Y2, the air dampers can be completely opened or
closed, independent of maxV and minV .
Full closure of the air volume occurs via the digital signal input Y2. If this input is
connected to ground (G0) and if signal input Y1 is open, full closure occurs without
consideration of minV .
The signal is triggered by an external switching contact (e.g. window contact) or theRCE84.21room temperature controller.

In order to utilise the VAV compact controller GDB181.1E/3or GLB181.1E/3without the
VAV/CAV controller, reset the "Function type" parameter of "VAV+CAV" to "3pt+sensor".
This can be done with the aid of setting unit AST10.
In order for the parameter change to become effective, voltage supply (AC 24 V) must
be interrupted.
With this function type setting, the VAV compact controller records the actual value for
the air volume in the air duct via the differential pressure p with static pressure sensor.
The differential pressure is converted electronically into an air volume signal which is
available at terminal UC as a DC 0..10 V output signal (air volume actual value).
Switching the terminal inputs Y1 and Y2 defines the direction of rotation of air dampers(3-position control).
The following table shows the influence of terminal switching on air damper control for
function type "3pt+sensor".

The VAV compact controller is designed for attachment on damper shafts that are at
least 30 mm long. It consists of a base group and a two-part housing.
The base group consists of:
a base plate made from steel with air damper attachment mechanism for varying shaftcross sections and diameters (see "Dimensions") and a rotary angle limiter
maintenance-free, noise-free spur gearing
magnetic hysteresis coupling with low contact power transmission and an actuator
that is thus protected against locking and overload, even during continuous operation
The housing is made from hard plastic. Do not remove its cover. The following is located
below the cover:
the controller electronics
the membrane pressure sensor with electronic circuit
the synchronous motor for damper actuation.
For manual adjustment of the air dampers, the gearing can be decoupled via the
gearing attachment mechanism on the side of the housing.A centring element made from hardened, sintered steel is available for the VAV compact
controller GLB181.1E/3(10 Nm) (separately supplied accessory). This ensures a proper
connection between damper shafts of smaller diameters (810 mm) and the connector
plug and the longitudinal movement of the VAV compact controller is reduced by means
of excentric movement.
The flows in the measured line are sufficiently low so that no contamination of the flow
sensor must be expected. In severely contaminated environments, we recommend
using the 4 287 1088 0air filter.
The mounting accessories (mounting bracket) as part of the delivery ensures full
adoption of the reaction torque to maximum load.
Electrical connection occurs via a fixed connecting cable at the bottom of the housing.
The cable ends are equipped with ferrules.

AC 24 V operating voltage is necessary for supplying the VAV compact controller.
The operating voltage must comply with the requirements for safety extra-low voltage
(SELV) as per EN 60 730.
Use safety insulating transformers with double insulation in accordance with
EN 60 742; The transformers must be made for 100% runtime.
Observe all local safety rules and regulations pertaining to sizing and protecting
transformers.
Electric connection in parallel of the VAV compact controllers GDB181.1E/3 withGLB181.1/3 is permissible only if the operating voltage is within the required tolerance.
Voltage drops at the feed lines must be considered.
Do not mechanically couple the actuators.
Selection of the VAV compact controller type depends on several torque factors. After
obtaining the damper torque rating (Nm/m2) from the manufacturer and determining the
damper area, calculate the total torque required to move the damper as follows:
Total Torque = Torque Rating Damper Area
Determine the required type of VAV compact controller from the table below:
If [ ])1SF
NmtorqueTotal then use type
5 Nm GDB181.1E/3(5 Nm)
10 Nm GLB181.1E/3(10 Nm)
1) Safety factor SF: When calculating, non-definable variables such as slight misalignment, damper
age, etc. must be included as a safety factor.
We recommend a safety factor of 0.80 (or 80 % of the torque characteristic).
Do not open the actuator!
The unit is maintenance-free. Any repair work must be conducted by the manufacturer
only.
The setting values for Vn , maxV , minV and the selected function type ('VAV+CAV' or
'3pt+sensor') must be entered in the plant papers.
There are no limits to the mounting position, however, the housing must remain
accessible (gearing attachment mechanism!). The cable connection for UC must be
accessible for the AST10 setting unit (e.g. terminal in the control cabinet).
Observe the permissible ambient temperature and humidity (refer to "Technical data").
The mounting brackets must be installed so that the pivot's insertion in the base plate of
the VAV compact controller's base group is sufficient and enough play is ensured
toward the shaft centre; this is necessary especially for small shaft diameters which
cause bigger excentric movements.
Use the centring element at shaft diameters of 810 mm to ensure a clean connection.
Mount this element between the damper shaft and the connector plug as per the
mounting instructions.
Manually adjust the actuator only when no voltage is applied.
Where required, you can set the rotational angle range by positioning the adjusting
screw accordingly.
The VAV compact controller is delivered with mounting instructions.

Check the mechanical settings as per the plant-specific requirements and especially
to ensure that the dampers close tight
Check the rotational direction
Use the red slider (while no voltage is supplied) to manually adjust the dampers or the
actuator.
Fasten the actuator securely to avoid side load and blocking of the actuator
Check lines for differential pressure measurement for correct connection
Check the settings at the DIL switches as per the plant documentation and seal them,
where required
The setting unit AST 10 is needed for checking or setting the setting values for Vn ,
maxV , minV and for the function type ('VAV+CAV' or '3pt+sensor'). After separating the
AST10 from the VAV compact controller, wait for one minute before Y, Y1 and Y2
work as per the specifications
The sensor signal is correct after a maximum of two minutes following application of
AC 24 V operating voltage or after interruption of the voltage supply. During this time,
the VAV compact controller conducts zero point calibration of the differential pressure
sensor
If the AST10 setting unit is connected, no analogue voltage can be measured at
output UC.

If a window contact, that was switched via terminal Y2 (core 7) of the GDB.../GLB...or
E1 of the RCE84.21, is open: Window closed, i.e., comfort mode. If this is not the case,
we must assume that the window is closed. For applications with complete closure of
the air volume, the terminals Y2 (core 7) of the reference controller and of the cascade
