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 before starting up the actuators, which exclude the danger of injury. For safety reasons, we recommend installing opening restrictors on bottom-hung windows. If windows are subjected to rain and/or high wind loads, we recommend connecting a wind/rain sensor to the motor controller for the automatic closing of the windows.The motor controller is to be located in a safe place, protected from the effects of fire and smoke. The motor controller is to be surface mounted. The motor controller is to be supplied with 230V AC. The manufacturer does not assume any liability for possible damage resulting from inappropriate use.

230V AC
230V AC can cause death, severe injury or considerable damage to assets. The connection of the motor controller is reserved for qualified personnel. Disconnect all poles of the motor controller from the supply voltage before 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 the opening speed. The cable cross-sections depend on the cable length and current consumption (amperage).

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.
The junction box must be accessible for maintenance purposes.
Disconnect all poles of the mains voltage before 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 following the technical information.
Cable specifications is a guide only, the overall responsibility resides with the electrical contractor on site. Installation must be per the national electrical regulations.

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 a fieldbus interface for KNX. If additional motor lines, inputs or fieldbus connection is required a Plus version of the MotorController is necessary . WINDOW-MASTER-WCC-320-Standard-Versions-FIG-1

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.

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“ and “MotorLink® actuators“.

The 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 the above formula.

Maximum actuator cable length: Always measured from the motor controller 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 0.75mm2 and actuator current 2A: (2 x 56 x 0.75) : (2 x 2) = 21m

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.

Connection of wind/rain sensors type WLA 330 or rain sensor WLA 331. Wind/rain sensor is connected to both WCA 3KI and WCA 3P6 on X9 and X2 respectively. S3.X9 is potential free / dry contact.

Data

9.1 close all / safety (all motor groups)
9.2 Momentary action / maintained action
9.3 GND / 0V
Momentary action: the actuator only runs for as long as the keypad is activated.
Maintained action: the keypad is activated shortly and the actuator runs until the keypad is re-activated.

With the default values are input:
”Active” if the contact resistance is smaller than 4kΩ ”Inactive” if the contact resistance is bigger than 8kΩ. For values between 4 and 8kΩ the result will depend on the supply voltage. Input has pull up approx. 1mA. (min 0.7mA, max 1.4mA)

Connection of wind/rain and rain sensors
WLA 330 and WLA 331– the settings of the sensors are set on the sensor. WINDOW-MASTER-WCC-320-Standard-Versions-FIG-18

DIP switch 1-3 on WLA 330 must be set for wind speed tolerances. Please refer to the installation instructions for WLA 330 for DIP switch settings. If no wind/rain or rain sensor is connected to S3X9, a 10kΩ resistor must be connected between S3X9.1 and S3X9.3.

S3 X10

S3.10 is potential free/dry contact.

Data:

10.1 Open all
10.2 Close all
10.3 GND / 0V

X10.1 and X10.2 have lower priority than the individual inputs X1-X8. X10.1 and X10.2 us blocked for a period of 30min after X1-X8 had received a command.

Configuration of the motor controller

The motor controller is configured by pressing the two keys ”↑” and ”↓” on the input card, at the same time for 10 seconds. The motor controller 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 motor controller

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.

Fault detection via LED

Fault detection on the motor controller
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 second 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.

Example of an error message
”7 blinks – 1sec. pause – 2 blinks – 1 sec. pause – 1 blink”.

There is an error on a local input
The error is on input X10.5, to which a rain sensor might be connected
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. The below table, lists the most common errors.

Hardware error

If there are any hardware errors on the MotorController it will be indicated by the diodes (yellow diode is lit).

Commissioning and test run

In case of hardware error please see Chapter 13 “‘Hardware error”. To configure the MotorController press „↑“ and „↓“ (on the input card) at the same time for 10 seconds, see chapter 11. We recommend that the software of the motor controller is updated the annual maintenance check!

The MotorController is completely installed, without the operating voltage applied

Check all mechanical and electrical components for damage.
Check all screw and plug connections for tightness and/or firm seating
Check that all external components are installed: 1) ±24V actuators: check polarity

With mains voltage
Adhere to the relevant regulations!
Connect the mains cables and reapply the mains voltage.

Ventilation keypad
Closely observe the actuators during opening and closing. They must not be impaired in any position by the building structure. Observe that the actuator cables are not being subject to pulling or pinching. Check each ventilation keypad individually.

Wind/rain detector

Open the actuators with the comfort ventilation keypads.
Wet the rain sensor, the actuators will fully close.
While the actuators are running, press the Open button at the keypad. The actuators must neither open nor stop! Exception: If a manual override time (Man. operation after auto comm.).

If the start-up was successful, mount the door of the MotorController. If the start-up was unsuccessful (error with one of the test run processes), please see chapter 10 “Description of cards”. If necessary, check the wiring in accordance with the cable plan – see chapter 9 “Cable plan for connection to WCC 3xx”.

Maintenance

The MotorController and ventilation system should be checked, serviced and, if necessary, repaired at least once per year by the manufacturer or an authorized partner Remove all soiling from the units of the ventilation system. Check fastening and clamping screws for firm seating. Carry out a test run of the entire system (see chapter 14 ‘Commissioning and test run). Only have defective units repaired in our factory. Only install original spare parts. Check the operational condition at regular intervals. We recommend a WindowMaster service contract is taken out to ensure the right function of the ventilation system. We recommend that the software of the MotorController is updated the annual maintenance check! The expected minimum lifetime for the MotorController is 10 years.
