1 Safety information
1.1 Safety
Only allow correspondingly trained, qualified and skilled personnel to carry out installation work.
Reliable operation and the avoidance of damage and hazards are only guaranteed if installation and settings are carried out
carefully in accordance with these instructions.
There may be personal danger by electrically operated windows:
- the forces occurring in the automatic mode can be such that parts of the body could get crushed
- when opened, actuators (spindles) could protrude into the room
For this reason, measures have to be taken prior to starting up the actuators, which exclude the danger of injury.
For safety reasons we recommend to install opening restrictors on bottom-hung windows.
In the event that windows are subjected to rain and/or high wind loads, we recommend connecting a wind/rain sensor to the
MotorController for the automatically closing of the windows.
The MotorController is to be located in a safe place, protected from the effects of fire and smoke.
The MotorController is to be surface mounted.
The MotorController is to be supplied with 230V AC.
The manufacturer does not assume any liability for possible damage resulting from inappropriate use.
1.2 230V AC
230V AC can cause death, severe injury or considerable damage to assets.
The connection of the MotorController is reserved for qualified personnel.
Disconnect all poles of the MotorController from the supply voltage prior to opening, installation or assembling.
Installation and use according to the national regulations.
1.3 Application
The MotorController is exclusively designed for the automatic opening and closing of windows, flaps or doors.
Always check that your system meets the valid national regulations.
Pay particular attention to the opening cross section, the opening time and opening speed.
The cable cross sections depend on the cable length and current consumption (amperage).
1.4 Cable routing and electrical connection
Fuse the 230V AC power supply cable separately on site.
Cable routing and connection - adhere to national regulations.
Establish the cable types, if necessary, with the local approval bodies.
Do not conceal flexible cables.
Junction box must be accessible for maintenance purposes.
Disconnect all poles of the mains voltage prior to starting maintenance work or making changes to the system.
Secure the system to prevent unintentional switching on again.
Route all low voltage cables (24V DC) separate from the power current cables.
Design cable types, lengths and cross sections in accordance with the technical information.
Cable specifications is a guide only, the overall responsibility resides with the electrical contractor on site.
Installation must be in accordance with the national electrical regulations.

2 Structure of the MotorController
Sizes & Versions
The WCC 310 and WCC 320 MotorControllers are available in two different versions namely a Standard and a Plus version.
This installation instruction only deals with the Standard versions. Please see separate installation instruction for the Plus
versions of WCC 310 and WCC 320.
Cards
Each MotorController contains a power supply unit (SMPS), either a WCA 3P3 or a WCA 3P5 for the 10A or 20A version
respectively, as well as a 5W auxiliary power supply for wind / rain sensor. Aside from the power supply units the Standard
version also includes a motorline card type WCA 3M4 or WCA 3M8 with 4 and 8 motor lines respectively and an input card
WCA 3KI with 10 inputs. Additionally, the Standard version is also available in a version with fieldbus interface for KNX.
If additional motor lines, inputs or fieldbus connection is required a Plus version of the MotorController is necessary.
Motor groups and motor lines
A motor group consists of one or more motor lines and all the motor lines are operated simultaneously.
All motor lines on the motor cards (WCA 3M4 & WCA 3M8) can be configured for either a ±24V standard actuators or
MotorLink®actuators. A motor group can contain motor lines with both ±24V standard actuators and MotorLink®actuators,
whereas a motor line only can have ±24V standard or MotorLink®actuators connected.

7 Installation
7.1 Cable routing
See also chapter 8 “Cable dimensioning” in this instruction. Do not reduce the
cable cross sections specified in the cable lengths table.
All cables of the control (except the mains supply cable) carry 24V DC and
have to be routed separate from the mains supply cable.
Adhere to the pertinent national and local regulations when routing the cables.
Ensure that the mains cable can be switched via an external or customer-
supplied two-pole switch element or a switch element controlling all poles –
see drawing.
7.2 Cables into housing
All connection terminals (except the mains terminals) are of the plug-in type.
Connect the connection cables in accordance with the terminal plan. Ensure that the connections are made correctly.
Incorrect cable clamping, mixing up numbers or colours could lead to malfunctions of the control MotorController or of the
external components.
Ensure that the electrical cables are always routed according to the valid national and local regulations.
7.3 Connection of safety earth wire and 230V AC
See chapter 10 ‘Description of cards’, for further description.
7.4 Installation of the ventilation keypad
Ensure that the ventilation buttons are visible and well accessible. Do not install behind protruding walls, door panels or hidden
by the building structure
7.5 Assembly instructions
Always have assembly, installation, repair and maintenance of ventilation systems carried out by qualified personnel
trained for this purpose.
Rules to be adhered to for setting up and installation
The following safety relevant rules have to be adhered to when planning the use of a ventilation system and its set-up and
installation:
•The Provincial Building Ordinance of the provinces
Accident prevention regulations
Adhere to the general accident prevention regulations (APR), the APR for power operated windows and doors, and the
installation rules in your country.
CAUTION:
Live components are directly accessible after opening the system housing.
Prior to inserting / removing cards disconnect to the MotorController from the mains supply.
•adhere to the installation instructions and your local energy providers
•select the place of installation such that free access is guaranteed for maintenance purposes
•select cables according to regulations in this instruction - take the calculation of the actuator supply cable lengths
into account when laying the cables
•connect the cables in accordance with the drawings provided by the manufacturer
•route the cables in the building according to the regulations in this instruction
•check all system functions

8 Cable dimensioning
8.1 Max. cable Length
Maximum permissible cable length from the MotorController to the actuators taking into account the cable cross-section is
shown in the following tables for “± 24V standard actuators“and “MotorLink®actuators“.
8.1.1 Formula for the calculation of the maximum actuator cable length
Max. cable length = permissible voltage drop 2V (UL) x conductivity of copper(56) x cable cross section in mm2(a)
max. actuator current total in amps (I) x 2
For both ±24V standard actuators and actuators with MotorLink® the cross section of the cable must not be less than 0.75mm2
regardless of the result of above formula.
Maximum actuator cable length: Always measured from the MotorController to the last junction box + cable to the motor
Permissible max. voltage drop in the line: 2 Volt
Actuating current: Sum of all actuator power consumption per motor line
Note: do not use the PE wire / green/yellow wire in the motor cable for communication!
Example
Max actuator cable length with cable cross section 0.75mm2and actuator current 2A: (2 x 56 x 0.75) : (2 x 2) = 21m
8.1.2 Max cable length –±24V standard actuators
The actuator supply cable must have 2 wires. If cable monitoring is requested min. 3: 2 wires current carrying / 1 wire for
monitoring.

10 Description of cards and mains connection
Each MotorController includes a main power supply unit (SMPS), an auxiliary power supply (AUX), a motor line card and an
input card.
The size of the power supply unit determines the number and/or types of actuators, which can be connected to the
MotorController. See table with overview of max number of allowed actuators per motor line/ MotorController (chapter 3.2).
10.1 WCC connection to mains and power supply units –WCA 3P3, WCA 3P5
and WCA 3P6
The MotorController WCC 310, is supplied with a 305W SMPS power supply –WCA 3P3.
The MotorController WCC 320, is supplied with a 605W SMPS power supply –WCA 3P5
The power supply is, regardless of size, placed in the bottom of the MotorController beneath the motor line and input card.
An AUX –WCA 3P6 –to which mains is connected, is located to the right of the power supply.
Outlet to mains is in the top of the MotorController.
The MotorController is grounded by means of protective earth via the green screw next to WCA 3P6.

The number of actuators per motor line depends on the actuator type, the total power consumption of actuators
connected to a motor line can max be 10A and the total max power consumption for both motor lines must not
exceed 10A or 20A depending on type of MotorController.
Besides actuators also locking actuators (espagnolettes actuators) type WMB 801/802 and WMB 811/812 can
be connected. The power consumption of the locking actuators are not to be included in the 10A / 20A as
actuators and locking actuators do not run at the same time.
All actuators on the same motor line will run/be operated simultaneously.
All actuators on the same motor line must be of the same type.
Connection / cable diameter: flexible max 6 mm² / solid max 10 mm².
Cable length: see the chapter "Cable dimensioning".

11 Configuration of the MotorController
The MotorController is configured by pressing the two keys ”↑” and ”↓” on the input card, at the same time for 10 seconds.
The MotorController must be configured
- After re-installation, changes, or change of actuators
- When / if MotorLink®actuators are connected
- If the cables have been moved
- When components are removed from the MotorController
Note, during reconfiguration actuator outputs can be activated in both directions.
If the yellow diode on the motor line card blinks after a configuration, an error has occurred in the configuration, see chaptor “Fault
detection via LED” for identification of errors.
Actuators are to be connected on the motor lines. ±24V standard actuators and actuators with MotorLink®can be connected to
all motor lines, but a motor line can only be connected to one type of actuators –either ±24V standard or MotorLink®actuators.
The MotorController will automatically detect the type of actuator, which is connected to the MotorController.
12 Fault detection via LED
12.1 Fault detection on the MotorController
In case of error on the MotorController, the yellow diode on the motor line card will blink and via blink sequence indicate an error
message. Depending on the type of error message will consist of 2 or 3 blink sequences, separated by a seconds pause. The first
blink in an error message has a duration of one second, and thereby indicating when the error message (1st blink sequence)
begins. The remaining blinks of the error message has a duration of 0.5 seconds. The error message is repeated until the error has
been rectified. Between 2 error messages there is a pause of 2 sec.

18
Example of an error message
”7 blinks –1sec. pause –2 blinks –1 sec. pause –1 blinks”.
1. There is an error on a local input
2. The error is on input X10.5, to which a rain sensor might be connected
3. The error is due to no connection to the sensor.
If there are more errors on the MotorController simultaneously, they are shown with priority, i.e. the error message for the most
critical error is shown first and repeated until rectified. Then the error message number 2 is shown and repeated as well until the
error is rectified etc. Below table, list the most common errors.
