10 Description of modules
10.1 WSA 5PS power supply module 20A
Each 20A section has a WSA 5PS
power supply module.
The module contains:
- one motor line (S1 X1) for ±24V
standard motors
- two free configurable inputs for
connection of e.g. wind/rain sensor
WLA 330 or keypad for comfort
ventilation
- one output for additional power
supply to sensors
- output for fault signal
- connection of power supply
- touch screen for configuration,
commissioning and maintenance
For connection of ±24V standard motors (total max 20A) and espagnolette actuators type
WMB 801/WMB 802/811/812.
All motors on motor line ‘S1 X1’ will run/be operated simultaneously.
Connection / cable diameter: flexible max 6 mm² / solid max 10 mm².
Cable length: see the chapter "Cable Sizing".
Examples with 20A power consumption
a) 20 pcs. WMX 824-1
b) 10 sets of 2 pcs. WMX 824-2
c) 4 pcs. WMU 885-1
d) 2 sets of 2 pcs. WMU 885-2
Connection of motors on motor line S1 X1
For connection of wind/rain sensor type WLA 330 or WLA 340, rain sensor WLA 331, keypad, Fire Alarm System etc.
For wind direction depending SHE - see chapter 10.2, section X3.
Data
2.1 Input
2.2 Input
2.3 GND / 0V
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 )
Input threshold is defaulted to ”1200” equal to 6.2V, given at approx. 6kΩ.
The threshold can be set in the interval 0..4095 bit, approx. 5.2mV/bit
