3 Product overview
3.1 Function
Sensor-control module with differential-pressure sensors in proven ceramic-cantilever
technology for climate and clean-room application.
The pressure range from 0 to 6000 Pa (24 in.wg) is covered with 3 types of device. With
each type four measuring ranges are programmable.
Function when the pressure at the “Plus”- connection exceeds the pressure at the
“Minus”- connection.
Depending on the programmed Mode the device can be used as sensor or as a
control module for pressure or volume flow.
•For operation as pressure sensor the device supplies an output signal (0...10 V)
proportional to the measuring range.
•For operation as volume flow sensor the device supplies an output signal (0..10 V)
proportional to the air volume measuring range (
INFO / Range qV). Function in
combination with centrifugal fans and measuring device in the inlet ring. The controller
calculates the volume flow of the fan from the “K-Factor” and pressure differential
between the suction side and the inlet duct.
•For operation as control module for pressure or volume flow the purpose of the device
is to reach and maintain the target value set. To accomplish this, the measured actual
value (sensor value) is compared with the adjusted target value, and the controlled
value is deduced from this. Controlled output (0...10 V) e.g. for activating a speed
controller for fans or an EC-fan directly.
The extended CPG-..AVC type version provides the following additional functions:
•Integrated real-time clock with timer function.
•Operating modes with setpoint adjustment based on outdoor temperature and input
for outdoor temperature sensor.
•RS-485 interface for MODBUS RTU.
•Signal relay that can be assigned different functions.
3.2 Storage
•The device must be stored in its original packaging in a dry and weather-proof room.
•Avoid exposure to extreme heat and cold.
•Avoid over-long storage periods (we recommend a maximum of one year).
3.3 Disposal / recycling
Disposal must be carried out professionally and in an environmentally friendly way in
accordance with the respective national legal stipulations.
"Separate the materials by type and in an environmentally friendly way.
"If necessary, commission a specialist company with the waste disposal.

4 Mounting
•Before installation remove the device from the packing and check for any possible
shipping damage!
•Assemble the device on a clean and stable base. Do not distort during assembly! Use
the appropriate mounting devices for proper installation of the unit!
•Use the templates printed on the device packing to mark the fastening bore holes.
•The pressure measuring depends on position, therefore the mounting must be made
vertical and as possible on a vibration-free place (cable inlet and pressure connec-
tions down).
•The pressure line´s connection should be with plastic-hose (in building), inside diam-
eter 4 / 5 mm. For a firm hold of the hose, its inside diameter must be 1 mm smaller
than the outside diameter of the hose nozzle (step spigot 5 / 6 mm).
•Remove the connection cover for mounting, electrical connection and setting of the
measuring range. Close the lid again carefully before start-up (tightening torque of the
lid screws 1.1 Nm).
•Two lines may only be fed through one cable screw-type gland with a sealing for two
lines.

5 Electrical installation
5.1 EMC-compatible installation of control lines
Pay attention to maintain sufficient distance from powerlines and motor wires to prevent
interferences.
When using a shielded cable the shield must be connected (as short and with as low an
induction as possible!) to the PE conductor on one side at the signal input (of the
evaluation unit).

5.2 Connection Voltage supply
Connection Voltage supply at terminals: “+U
S
” and “GND”. Here, it must be strictly
observedt hat the mains voltage lies within the llowable olerance pecifications (see
Technical data and nameplate affixed to the side).
Danger due to electric current
Only PELV current sources which ensure safe electrical isolation of the operating voltage
in accordance with IEC/DIN EN 60204-1 must be used.
There is no potential isolation between supply voltage and output signal.
5.3 Output voltage 0...10 V
Connection to terminals “A” and “GND” (I
max
see Technical data).
Parallel control of several speed controllers / EC-fans
The maximum possible number of speed controllers / EC fans with 0...10 V input that
can be controlled parallel depends on their input resistance and on the maximum
admissible load of the 0...10 V output.
Example:
•Supply voltage CPG / CTG: 10 V > I
max
for 0...10 V output 0.3 mA (see Technical
data or connection diagram).
•ECblue motor size B: Input resistance R
i
> 100 kΩ (Assembly instuctions fan
seeTechnical data or connection diagram).
•The current consumption for one fan is max. 0.1 mA (I U / R 10 V / 100 kΩ)
✓Result:
A maximum of three ECblue motor size B can be operated in parallel at one CPG /
CTG (total current consumption ≤ I
max
0...10 V output CPG / CTG).
Attention!
•It is not permissible to connect outputs of several devices to each other!
•In case of failure of the control module or interruption of the 0...10 V specification
signal, all parallel connected EC fans/speed controllers are no longer controlled. This
means that all fans stop!

Addressing Addressing
The connections for MODBUS “A (D+)”, “B (D-)” are available double on the module and are
connected with each other internally.
Information
•You must ensure correct connection; i.e. “A (D+)” must also be connected on the
following devices to “A (D+)”. The same applies to “B (D-)”.
•In addition, a "GND" connection must be established, as dissimilar potential (over 10
V!) will lead to the destruction of the RS-485 interface (e.g. lightning).
•Except the data link “A (D+)”, “B (D-)” and “GND” (for automatic addressing additional
“ID1” - “ID2” see following chapter) no further cable cores of the data line may be used.
•Pay attention to sufficient distance from powerlines and motor wires (min. 20 cm).
•A maximum of 64 participants can be directly connected to one another, and another
64 participants via a repeater.
Example for MODBUS connection
MODBUS
26.02.2007
v_modbus_verbindung.vsd

2. J-Y (St) 2x2x0.6 (telephone cable)
3. AWG22 (2x2 twisted pair)
Max allowed wire length 1000 m (CAT5/7 500 m).
Shielding
The use of shielded cables is normally not needed but offers high protection against
electromagnetic interferences, especially high frequencies. However, the effectiveness
of the shield depends on careful installation of the line.
If shielded cables are used, the shield should be placed at “PE” on at least one side
(preferably on the master connection). The occurrence of compensating currents may
have to be considered if the shield is contacted on both sides.
Shield connection correct Shield connection incorrect
When using telephone cable with four cable cores, we recommend the following
allocation:
•A (D+) red
•B (D-) black
•ID1 - ID2 yellow (for automatic addressing)
•GND white
Default interface parameter
•Baudrate 19200
•Bits 8
•Parity Even
•Stop bits 1
•Handshake none
Information
•Addressing is performed depending on version by display, an external terminal or a
PC with the appropriate software (automatic addressing following chapter).
•The MODBUS register description and the information sheet “Network structure of
MODBUS” can be requested from our Support Department V-STE for control systems
