3 Product overview

3.1 Operational area

The devices are designed as temperature control units for stable compartments in single or central

exhaust air installations.

•In installations with single suction, fans, aps and heatings are controlled via the outputs.

•In central exhaust installations, these devices are used in combination. The devices controls

the exhaust air ap and the heatings for one compartment. At the same time the exhaust air

volumes of all the compartments connected are signaled to a Master*. The speed is calculated

from the sum of the exhaust air volumes and the fans connected are readjusted.

In order to be able to network several devices, these are equipped with a bus interface. In this way, for

example, the supply air temperature sensor connected to the Master* can be communicated to all

system users. Fault messages on stall devices are transmitted and displayed as a group fault; in

addition the total exhaust air volume of the ventilation system is determined.

UNIcon Type CTE/AH(X)-L

The control module Unicon type CTE/A(X)H-L has signal outputs e. g. for the control of ETAvent fans

and damper control motors.

Acontrol Type PTE-6AHQ(X)-L and PTE-10AHQ(X)-L

The voltage controllers model range Acontrol type PTE-6AHQ(X)-L and PTET-10AHQ(X)-L have an

operating output for voltage-adjustable 1~ motors with a maximum control current of 6 A or 10 A.

Master*

A device which controls and monitors the bus communication and performs central control functions

3.2 Maintenance

The device must be checked for soiling and, if necessary, cleaned in periodic intervals.

3.3 Transport

•The device is packed ex factory to suit the transport method previously agreed.

•Always use the original packaging materials when transporting the device.

•Avoid shocks and impacts to the device during the transport.

•During manual handling the human lifting and carrying restrictions must be observed and

adhered to.

3.4 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).

4 Mounting

4.1 General notes

Attention!

The following points must be complied with during the mechanical installation to avoid causing a defect

in the device due to assembly errors or environmental inuences:

•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!

•Do not mount equipment on vibrating base!

•When mounted onto lightweight walls, there must be no impermissibly high vibrations or shock

loads. Any banging shut of doors that are integrated into these lightweight walls, can result in

extremely high shock loads. Therefore, we advise you to decouple the devices from the wall.

•Do not allow drilling chips, screws and other foreign bodies to reach the device interior!

•The plastic washers must be installed between the screw heads and the housing for models

with mounting holes on the inside of the housing!

•The device should be installed in a location where it will not be disturbed, but at the same time

can be easily accessed!

•Depending on the housing model use supplied stoppers for cable inlets, cut off necessary cable

inlets respectively to the cable diameter. Or alternative use cable inlet for cable glands. Any

cable ducts openings not used must be sealed!

•Care must be taken to avoid direct radiation from the sun!

•The device is designed for vertical installation (cable inlet down). A horizontal or reclined

installation is only permissible after technical release of the manufacturer!

•Be sure to observe proper heat dissipation ( Technical data, heat dissipation).

4.2 Minimum space requirement

In order to ensure sufcient ventilation of the device, clearance on all sides of at least 50 mm has to

be maintained to the housing walls, switch cabinet doors, wiring ducts, etc. The same clearance

applies to the installation of several devices next to each other.

When installing several devices on top of each other, the danger of reciprocal heating exists. This

layout is only then permissible when the air suctioned from the upper unit does not become warmer

than the permissible ambient temperature ( Technical data). I.e., a correspondingly larger clearance

or thermal shielding is required.

4.3 Outdoor installation

Outdoor installation is possible up to -20 °C when the controller supply is not switched off. Installation

must be protected from the effects of weather as much as possible, including protection from direct

sunlight!

4.4 Installation location for agriculture

In order to avoid damage caused by ammoniac vapours, the controller shall not be installed in the

stable, but rather in an outhouse wherever possible.

4.5 Temperature inuences during commissioning

Avoid condensation in the controller and hence functional faults attributable to condensation by storing

the controller at room temperature!

5 Electrical installation

5.1 Safety precautions

Danger owing to electric current

•Work on electric components may only be carried out by trained electricians or by

persons instructed in electricity under the supervision of an electrician in accordance

with electrical engineering regulations.

•It is forbidden to carry out work on electrically live parts.

•A second person must always be present when working on energized parts or lines who

disconnects in case of emergency.

•Inspect electrical equipment periodically: retighten loose connections –immediately re-

place damaged lines and cables.

•Always keep switch cabinets and all electrical supply facilities locked. Access is only

allowed for authorized persons using a key or special tool.

•Operating the device with the housing cover removed is prohibited because energized,

exposed parts are present inside the device. Disregarding this regulation can lead to

severe personal injury.

•The required protective earth connection is established using screws between the hous-

ing parts in metal terminal space covers and housing casings. Commissioning is only

permissible after these screws have been properly attached!

•Metal screwed-connections are not permitted in plastic housing parts because there is

no potential equalization.

•Never clean electrical equipment with water or similar liquids.

Information

The respective connections are represented in the enclosure of this manual ( Connection diagram)!

5.2 EMC-compatible installation

5.2.1 Motor feeder cable

The applicable standard for interference emissions is EN 61000-6-3. Compliance with this standard is

achieved through the use of an unscreened motor feed cable.

5.2.2 Signal cable

Pay attention to sufcient distance from powerlines and motor wires to prevent interferences. The

control cable may not be longer than 30 m. Screened control cables must be used when the cable

length is longer than 20 m. When using a shielded cable connect the shielding to one side only, i.e.

only to the control unit with the protective ground (keep cable short and with as little inductance as

possible!).

5.3 Mains connection

Power from the mains is connected to terminals: PE, L1 and N. Here, it must be strictly observed that

the mains voltage lies within the allowable tolerance specications ( Technical data and nameplate

afxed to the side).

Danger owing to electric current

The mains voltage must comply with the DIN EN 50160 quality characteristics and the dened

standard voltages in IEC 60038!

5.4 Fan connection

5.4.1 Control module type CTE.. for ETAvent-fans

The connection of ETAvent-fans depends on the version. For an inverted control (10 - 0 V, 100 - 0 %

PWM) an accordant programming at the base menu is necessary ( IO Setup ).

Information

For use of ETAvent fans (version 0 - 10 V / 10 - 0 V) in central exhaust air installations the controller

output 1(terminals A1 / GND) is used for the exhaust air damper. The ETAvent is then connected to a

controller output which has to be programmed ( Installation - IO Setup).

5.4.2 Voltage controllers type PTE.. for 1~ fans

The motor is connected at terminals U1 and U2. Several motors can be connected to the device.

Attention!

The maximum total control current (specied for electronic voltage regulation) for all motors

may not exceed the device’s rated current.

If the maximum control current for electronic voltage regulation is not known, a supplementary

20 % of the rated motor current must be allowed for.

When controlling motors from other manufacturers, the controllability and the maximum

current for electronic voltage regulation should be requested from the manufacturer.

Information

•It is recommended that a separate motor protection unit be foreseen for each fan.

•For motors with thermistors “TB”e.g. type S-ET10.

5.4.2.1 Running noise

When controlling ventilators using electronic voltage regulators, motor noise can occur (due to the

system), which can be troublesome (Phase cutting = series “P...”).

On fast running ventilators with a high level of air noise, this noise is relatively low. On slow running

ventilators with a low level of air noise, this noise may be dominant in the lower speed range due to

the occurrence of resonance.

For systems where noise is critical, we recommend using our ETAvent fans in combination with

ventilation computer without power stage type CTE/AH(X)-L.

5.5 Motor protection

Attention!

Motor thermostats cannot be connected to these controller. I.e. a separate motor protection is

required. We cannot under any circumstances accept liability for damage to the motors which

do not have the required motor protection. It is recommended that every fan is equipped with a

separate motor protection unit e.g. type S-ET10 ( connection diagram)!

The existing malfunction entry (terminals D3-*D3) can only be used for display of the existing

malfunction.

•For voltage controllers type PTE.. e.g.. when a motor protection unit has tripped

•For control module type CTE.. fault indication ETAvent-fan

The fault display also disappears as soon as the fault has been eliminated. The fault can be

acknowledged by pressing the

ESC

key. If the fault persists, after approximately 60 minutes (time

span can be adjusted under “Alarm”)“Alarm Ventilator”reappears.

5.6 Analog inputs for sensors

Input E1 for temperature sensors in compartment

•Terminals “E1”/“GND”

•Sensor type TFR (Part.-No. 00089846) in scope of delivery

Input E2 (function programable)

•Terminals “E2”/“GND”

•Sensor not in scope of delivery

•For example for measuring the supply air temperature in single devices or for networking only

on the “Master”device. When networked, the supply air temperature is transferred via bus from

the “Master”to the other devices.

•For example temperature sensor for controlling the heater or shutter independently of the sensor

in the stall (separate control circuit).

•For humidity sensor with 0 - 10 signal (e.g. type MFTG-100V Art. No. 384033). The internal

plugs for input 2 must be plugged to 0 - 10 V ( humidity control).

5.7 Control output A1, A2, A3 (0 - 10 V) and PWM

The devices have three 0 - 10 V outputs and one PWM output (alternative use as a further 0...10 V

output).

It is not permissible to connect outputs of several devices to each other!

The following functions are pre-programmed at the factory (other functions can be assigned in

the IO Setup):

0 - 10 V Output:

•Output 1: terminals “A1”/“GND”(I

max

10 mA). For ETAvent fans with 0 - 10 V signal or exhaust

air dampers in the compartment (IO Setup: A1 function = “0”→ventilation)

•Output 2: Terminals “A2”/“GND”(I

max

10 mA). Regulator 2 e.g. for throttle shutter after the

exhaust air fan in the stall (IO Setup: A2 function = “2”→shutter) factory inverted (10 V...0 V)

i.e.: 10 V = shutter CLOSED, 0 V = shutter OPEN

•Output 3: Terminals “A3”/“GND”(I

max

10 mA). For Heating (IO Setup: A3 function = “1”→

Heating )

PWM output alternatively 0 - 10 V

•Output PWM: terminals PWM / +24V. For ETAvent fans with PWM input (IO Setup: PWM

function = “0”→ventilation)

•To change to 0 - 10 V output plug internal jumper “J1”at the top!

Information

Inverting outputs and setting curve points possible (e.g. for not linear ouput) in IO Setup ( Installation

menu).

5.8 Voltage supply for external devices (+24V, GND)

There is an integrated power supply for external devices, e.g. a sensor. Terminal +24 V, output voltage

tolerance +/- 20%. max. load current Technical data.

It is not permissible to connect outputs of several devices to each other!

In case of overload or short circuit (24 V –GND), the external power supply is shut down (multi-fuse).

The device performs a “Reset”and continues operation.

5.9 Relay outputs (K1, K2, K3)

The device has three relay outputs, the following functions are pre-programmed at the factory. Other

functions can be assigned in “IO Setup”. Max. contact load 5A / 250 V AC.

K1: Fault indication

•Connection of the oating contacts to the terminals 11, 12, 14.

•For operation the relay is energized i.e. terminals “12”and “14”are bridged (factory setting not

inverted).

•With power failure, internal fuse failure, temperature malfunction or fan error, the error message

relay at the corresponding control unit of the compartment drops, the terminals “12”and “11”are

bridged. The “Master”unit identies a malfunction of a network user via the data link, i. e., if a

network user displays a malfunction, the error relay in the master unit also drops. Due to this

function the fault relay of the “Slave”devices can be assigned if necessary different functions.

•The fault message via the relay can be acknowledged with the “ESC”key. If the fault persists

(e.g. sensor break) a message is received again after the adjustable time span “Alarm Pause”

(factory setting 60 minutes).

The error message is not to be layed in the same cable as the bus line.

K2: Heating

•Connection of the oating contacts to the terminals 21, 22, 24.

K3: Peak load fan

•Factory setting relay “K3”for function “peak load fan ”assigned( “Installation”-“IO Setup”).

A second fan can be switched on via the terminals “31”und “32”.The activation must be made in

“Installation”-“Ventilation”(peak load).

Information

Inverting relay function in IO Setup( menu installation) possible.

5.10 Communication

5.10.1 Network by Modbus

The device comes equipped with a RS-485 interface for networking via a Modbus. Connection to

terminals “D+”,“D-”and “GND”.

A maximum of 32 network users can be connected to the data bus. One of these devices is the

Master.

The Master always has the address 1(display of address in installation menu:- - - - -).

The address must be set in the “Bus”menu. The sensor for the supply air and the group fault

must be connected at the “Master”device!

5.10.2 RS-485 - network design and interface parameter

You must ensure correct connection; i.e. "D+" must also be connected on the following devices to

"D+". The same applies to "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).

general example for Modbus device connection

The data line must be conducted from one device to the next. No other type of wiring is allowed!

Always use only two wires of one lead (twisted pair) for the connection.

Examples for Modbus connection

Recommended wire types

1. CAT5 / CAT7 cables

2. J-Y (St) 2x2x0.6 (telephone wire)

3. AWG22 (2x2 twisted pair)

When using telephone ex with four cable cores, we recommend the following allocation:

“D+”= red, “D-”= black, “GND”= white

Information

•Pay attention to sufcient distance from powerlines and motor wires (min. 20 cm)

•Do not use wire shield

•Except the data link " D+" , " D-" and " GND" - connection may no further cable cores of

the data line be used.

Information

If any matters are unclear, please contact our V-STE support department for control systems -

ventilation technology. The information sheet "Network structure of Modbus" R-TIL08_01 contains

detailed information about Modbus.

5.11 Potential at control voltage connections

The control voltage connections (< 50 V) relate to the joint GND potential (Exception: Relay contacts

are potential free). There is a potential separation between the control voltage connections and the

earthed conductor. It must be ensured that the maximum external voltage at the control voltage

connections cannot exceed 50V (between “GND”terminals and “PE”earthed conductor). If necessary,

a connection to the earthed conductor potential can be established, install bridge between “GND”

terminal and the “PE”connection (terminal for screening).

5.12 Zenec main switch for ETAvent fans

With ETAvent fans an emergency operation at maximum speed is possible (100 % function)

in the case of a fault in the master control technology or failure of the preset signal (0 –10 V

or PWM signal).

Type Zenec, Part. no. 349022

Switch position:

•Position

: Switches off the fan (lockable)

•Position

: Operation Control

•Position

100 %

: fans supporting the 100 % function run with maximum speed.

Technical data:

•Housing protection IP65,

•Dimensions (w x h x d) 86 x 121 x 117

•Contact rating AC 250 V 20 A

Feature:

By connection of the terminals “7”and “8”in the “Zenec”according to the circuit diagram ( Appendix

–Connection Diagram ETAvent), a fault message can be suppressed in switch position “0”(fault

message via the integrated fault message relay in the ETAvent fan).

If this fault message is not suppressed in switch position “0”the terminals do not have to be

connected.
