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 0.75mm2and 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 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!

10 Description of cards and mains connection
Each MotorController includes a power supply unit (SMPS), an auxiliary power supply (AUX) and a main control card. Motor line
can input cards for additional motor lines and inputs (e.g. for key pads) as well as a field bus card can be added when necessary.
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).
WCC connection to mains and power supply units –WCA 3P3, WCA 3P4
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 3P4.
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 right 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 4A and the total max power consumption for both motor lines must not
exceed 10A or 20A depending on MotorController type.

15
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
actuaators 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.

X11
For connection of master / slave connection via WSK-Link™.
Data:
11.1 24V IN
11.2 Communication IN
11.3 0V IN
A master-slave connection via WSK-Link™ enables signals to be distributed between several MotorControllers
or/and the MotorController may be used as slave in a 120V UPS smoke ventilation system.
On the master MotorController, either use input X5 or X6 for the master-slave connection. On the slave
MotorController, the connection is done via X11.
It is possible to connect several MotorControllers in a master slave connection. However, the max total number
of MotorControllers on the WSK-Link™ must not exceed 10 units. The max cable length between two units must
not exceed 200m, see examples below, for how to connect the MotorControllers.
Sharing of signals from weather station
Example 1
Example 2
MotorController #2 and #3 are both master and salve MotorControllers.
See under X10 for connection of weather station
WCC 3xx as slave in a 120V UPS supplied smoke ventilation system
Example 1
Example 2
See WSC 3xx instruction for further information about connection to smoke ventilation system.

20
Even though the connecting method of MotorControllers shown in the #2 example, enables a physical larger
system, with longer distances between MotorControllers, WindowMaster recommends connecting the master
slave MotorControllers as shown in example #1. As only the master sends e.g. smoke commands and slaves
only respond to commands received from the master, the response time in example 2 is heavily increased in
comparison with the response time in example 1.
