WINDOW MASTER WCC 103 Motor Controller

Safety regulations

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 from 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 MotorController is supplied by 230V AC.
• The manufacturer does not assume any liability for possible damage resulting from inappropriate use.

230V AC

• 230V AC can cause death, severe bodily injury, or significant property damage.
• The motor controller must be disconnected from the power supply before being opened, mounted, or performing any alteration of the construction.
• Power supply to the MotorController must be done via an external two-pole or multi-pole circuit breaker. The motor controller is to be supplied with a Phase conductor, Neutral conductor, and Earth conductor
• Applicable national regulations must be complied with.

Application

• The MotorController is solely designed for the automatic opening and closing of windows, flaps, and doors.
• Always check that the system complies with applicable national regulations.
• The cable cross-section will depend on wire length and power consumption. See chapter “Cable dimensioning”.

Cabling and electrical connection

• WindowMaster recommends powering the MotorController from its own group.
• 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 (24VDC) separate from the power current cables. Design cable types, lengths, and cross-sections per the technical information. Cable specifications are a guide only, the overall responsibility resides with the electrical contractor on site. Installation must be per the national electrical regulations.

Introduction to WCC 103

• WCC 103 is a motor controller that controls (opens/closes) 1 or more ±24V standard window actuators based on a signal from the connected components, e.g. comfort keypad (operating keypad) room sensors and weather sensors.
• We recommend always connecting the comfort keypad when sensors and other operators are connected so that users always, via the comfort keypads, can override the signals and open or close windows themselves should there be a need for more or less fresh air.

The MotorController’s construction

• The MotorController contains a 75W primary power supply (SMPS-switched mode power supply) and a printed circuit board with input, output and auxiliary supply (AUX).
• WCC 103 has 1 motor line to which ±24V standard actuators can be connected; the number of connected actuators depends on the actuator type; the following table lists the max number of actuators. Total power consumption for all connected motors incl. load on X7 (AUX max. 0.5A) may not, however, exceed 3A.

• The MotorController is fixed to the wall through the back plate’s Ø4.5 mm mounting holes.
• The motor controller should be mounted in a secure location so that it is protected against the effects of fire and smoke.

Installation

Cable routing
The safety regulations in these guidelines must be closely followed. Regarding low-power cable configuration, we refer you to the chapter “Cable dimensioning”. The cable cross sections listed in the table of cable lengths must not be reduced.

• The cables are led into the MotorController’s cabinet via cut-outs in the bottom.
• When routing cables, all applicable national regulations must be complied with.
• The MotorController is supplied with a 1.2 m cable with a Schuko plug.

Connecting cables in the motor controller

• Cables are to be connected per the chapter “Connection plan for WCC 103”, the short chapters, and other relevant paragraphs in these guidelines.
• Please ensure that connections are correctly executed – incorrect connections can lead to functional failure in the MotorController or external products.
• The installation must at all times adhere to the applicable regulations, standards, and guidelines.

Connecting protective earth and 230V AC
WCC 103 is factory-fitted with a power supply cable with a 230V Schuko plug with earth wire.

Installation of comfort keypad
The comfort keypad should be mounted in a visible position and within easy reach.

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:
If internal coverings are removed the live current parts are exposed.

Guidelines for mounting/installation

• the motor controller should be mounted on the wall in such a way that there is free access for service inspections
• 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’s supply cable lengths into account when laying the cables
• connect the cables by the drawings provided by the manufacturer
• route the cables in the building according to the regulations in this instruction
• check all system functions

Cable dimensioning

Cables should be routed in compliance with applicable regulations.

Max. cable length
The maximum permitted cable lengths from the motor controller to the actuators, taking into account the cable cross-section, are shown in the following table.

The formula for calculating max. actuator cable length
Max. cable length = permitted voltage drop 2V (UL) x copper’s conductivity (56) x cable cross-section in mm2 (a) Max. total actuator current per motor line in amperes (l) x 2

For ±24V standard actuators, the cable cross-section may not be less than 0.75 mm2, irrespective of the result of the above formula.

• Maximum actuator cable length: Always measured from the motor controller to the last junction box + actuator cable Permissible max. voltage drop in the line: 2 Volt
• Total actuator current: The sum of all the connected actuators max. current 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 of 0.75mm2 and 2A current consumption: (2 x 56 x 0.75) : (2 x 2) = 21m

Max. cable length – ±24V standard actuators
The actuator cable must have 2 wires minimum.

LED 1

| The yellow LED indicates an error on the motor controller. If the diode is off, there is no error/failure.

See chapter, “Status and troubleshooting via LED” for more information.

LED 2

| The green LED that shows the status of MotorController. If the diode lights constantly, there is no error/failure.

See chapter, “Status and troubleshooting via LED” for more information.

LED 4

| The green LED shows the status of the motor line.

If the diode lights for 2.4 sec, and is off for 0.8 sec (repeated continuously) there is no error/failure on the motor line. See chapter, “Status and troubleshooting via LED” for more information.

Status and troubleshooting via LED

• In the event of failure/error of the motor controller, one or more diodes will light and/or blink.
• On the WCC 103, there are 3 diodes – 2 green and 1 yellow – that can indicate errors on the motor controller.
• Irrespective of which diode lights or blinks, the indicator is based on a 3.2-second sequence that is repeated continuously. Each sequence is defined by 32 x 0.1 second time segments.
• If there are several errors on the MotorController simultaneously they are displayed by priority, i.e. error messages for the most critical failures are shown first and repeated until the failure is remedied. Then error number two is shown, which likewise is repeated until the error is remedied etc. The following overview shows the most frequently occurring errors, if an error other than those listed below is indicated, contact WindowMaster.

Yellow diode – LED 1
If the yellow diode lights, this indicates an error on the motor controller.

• Black = diode off

The error indicator on the yellow diode is a total error indicator. Detailed information on the error type can be decoded on the green diode.

Green diode – LED 2
If the green diode LED 2 (closest to X10) blinks, this indicates an error on the motor controller.

• Black = diode off

Green diode – LED 4
The green diode LED 4 (furthest from X10) indicates the status of or error on the motor line.

• Black = diode off

Commissioning and test run

In the event of error messages, refer to chapter “Status and troubleshooting via LED”.

MotorController fully installed, without operating power

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

With network power

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

Comfort keypad
Look closely at the actuators as they open and close – there must not be any obstacles in any position and the actuator connection wires must not be overstrained with pulling or pinching.

• Test every single comfort keypad.

Wind/rain sensor

1. Open the actuators with the comfort keypads.
2. Dampen the rain sensor, and the actuators close completely.
3. While the actuators are running, press the Open button on the comfort keypad. The actuators must neither open nor stop.

• If commissioning proceeds correctly, the lid of the MotorController may be fitted.
• If commissioning does not proceed correctly, i.e., there is an error in one of the test points, refer to chapter “Connection description” If necessary, re-test the cable routing by chapter “Connection plan for WCC 103”.
