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 fieldbus interface for KNX.
If additional motor lines, inputs or fieldbus connection is required a Plus version of the MotorController is necessary.
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.
