1 Safety information

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 supplied by 120 V AC
The manufacturer does not assume any liability for possible damage resulting from inappropriate use.

120V AC

120V 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.

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).

Cable routing and electrical connection

Fuse the 120VAC 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 (24VDC) 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 Plus versions. Please see separate installation instruction for the Standard
versions of WCC 310 and WCC 320.

Cards

Each MotorController contains a power supply unit (SMPS), either a WCA 3P3 or a WCA 3P4 for the 10A or 20A version
respectively, as well as a 5W auxiliary power supply. Aside from the power supply unit the Plus version also includes a main
control card type WCA 3CP, which includes a touch screen for easy configuration of the MotorController. Motor line and input
cards, as well as fiedbus cards, can be added to the MotorController depending on requirements.

Selection of cards

The Main control card type WCA 3CP allows connections of 2 motor lines and 2 keypads. If more than 2 motor lines or 2
keypads are required, the necessary cards can be added.
Cards:

- WCA 3M4 motor line card, allows additional 4 motor lines.

- WCA 3M8 motor line card, allows additional 8 motor lines.

- WCA 3KI input card, allows additional 10 keypads (requires WCA 3M4 or WCA 3M8).

A fieldbus card must be added, if communication via KNX or BACnet is required.
Fieldbus cards:

- WCA 3FK fieldbus card, fieldbus interface for KNX

- WCA 3FM fieldbus card, fieldbus interface for BACnet / MSTP

- WCA 3FB fieldbus card, fieldbus interface for BACnet IP

Installation of cards may only be done when there is no power on the MotorController. Motor line and input cards are ordered
together with the MotorController and mounted to the MotorController from the factory side, whereas the fieldbus cards are
delivered as individual products and are to be mounted by the customer – see separate installation manual for mounting of
fieldbus card.

The item no. of the MotorController specifies the type and mounting of the cards - see "Variants of MotorController" for more
information

Motor groups and motor lines

A motor group consists of one or more motor lines and all the motor lines are operated simultaneously.
The motor lines on both the main control card (WCA 3CP) and the motor line cards (WCA 3M4 or WCA 3M8) can all 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 motorline only can have ±24V standard or MotorLink® actuators
connected.

Adding MotorControllers

The natural ventilation installation can be expanded by adding more MotorControllers and creating a master/slave connection
among them. The master/slave connection is done directly on the WSA 3CP card. The total cable length between 2
MotorControllers must not exceed 200m.

8 Cable dimensioning

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“, “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 + actuator cable
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 actuator cable!

Example

Max actuator cable length with cable cross section 0.75mm2 and 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 monitoring is desired use min. 3: 2 wires current carrying / 1 wire for monitoring.

±24V standard actuators

Do not use the PE wire / green/yellow wire!
