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...
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.

Installation 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.
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“. 8.1.1 Formula for the calculation of the maximum actuator cable length Max.

® When using actuators with MotorLink the max cable length is 50m regardless of the result of the above mentions formula. Actuators with MotorLink ® Do not use the PE wire / green/yellow wire! cable cross 3 wire 3 wire 5 wire 3 wire 5 wire...
10.1 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.
10.2 Motor line card WCA 3M4 and WCA 3M8 The motor line cards WCA 3M4 and WCA 3M8, allows connection of 4 and 8 motor lines respectively either ® ±24V standard or MotorLink WCA 3M8 – motor line card with 8 motorline WCA 3M4 and WCA 3M8 has 4 and 8 motor lines respectively for connection of either ±24V standard or X1 –...

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. 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.
Power supply card – WCA 3P6 10.4 Mains and protective earth is connected to the MotorController via the power supply card. On the standard version of the MotorController the power supply card enables connection of weather station or other sensor. S4 X1 Connection to mains.
Example of an error message ”7 blinks – 1sec. pause – 2 blinks – 1 sec. pause – 1 blinks”. 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.
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).
