Trox Technik Compact XM0, Installation And Commissioning Instructions

Page: 28 / 45

The GUIV3-M adjustment device offers the same range
of functions as the internal display of the control compo-
nent, setting via this display is useful if the control com-
ponent is difficult to access due to an unfavourable
installation orientation. Connecting and patch cables
allow for easy commissioning. All illustrated connecting
cables, software and operating instructions are included
in the supply package of the adjustment device,
rechargeable battery 2.4V (2x AA Ni-Mh) not included.
To ensure proper operation of the adjustment device,
use the cables included in the supply package.
8.3 PC software WINVAV2
Fig. 28: Connection to the PC with interface adapter
GUIV3-S
With the WINVAV2 software, actual values can be read
and parameterised and time diagrams can be created.
The software is installed on a customer PC.
The control component is connected to the GUIV3-S
interface adapter with a service plug and patch cable.
The USB cable is then used to connect the PC and
GUIV3-S. The software comes with the GUIV3-S inter-
face adapter, all the connecting cables shown, and the
operating instructions. To ensure proper function, the
cables in the supply package must be used.
8.4 Functional test
Personnel:

Skilled qualified electrician

HVAC technician
For commissioning, we recommend creating commis-
sioning documentation in which the function of the ter-
minal unit is checked and documented.
The function test of the terminal unit can be carried out
in various ways,
Ä
Chapter 8.2 ‘Service tools func-
tional overview’ on page 27 .
The internal display is sufficient for most function tests,

on page 23
To check the function of the VAV terminal unit, check the
position of the damper blade on the damper blade shaft
(marked),
Ä
3.2 ‘Position of the damper blade’
on page 10 .
Preparation:

Switch on the supply voltage; the green LED indi-
cates that the supply voltage is properly connected.

Wait until the synchronisation run has been com-
pleted.

Switch on air conditioning system.
Note: The system pressure at the volume flow con-
troller must be sufficient for a proper function test.

The test function is started and the LED
flashes once briefly at 2-second intervals.

Measure the actual value signal with a volt-
meter, read the volume flow rate actual value
on the display and log it.
8.5 Setting of the control component
8.5.1 Setting constant value operation (F)
If the factory-set value qv
vconst
is to be changed, or an
ordered variable volumetric flow controller is to be con-
verted to a constant volumetric flow controller, this can
be adjusted on the internal display or via the service
tools described. Here, the constant value is set to q
vmin
.
Since q
vmin
= q
vconst
with constant control. In this case,
the q
vmax
value has no relevance and no further setting
is required.
For constant value operation, no control signal may be
specified at terminal Y.
