Standard
±24V
Example with max. 3A current
consumption
a) 3 pcs. WMX 826-1
b) 2 sets of 3 pcs. WMX 504-3
c) 1 pc. WMU 883-1
d) 2 pcs. WMU 861-2
X2 Input for connection of comfort keypad
Data:
2.1 Open
2.2 Close
2.3 GND / 0V
With the factory-set values the input is:
"Active" if resistor is less than 5kΩ
"Inactive" if resistor is greater than 8kΩ.
Input has pull-up current of approx. 1mA (min. 0.9mA, max. 1.1mA)
if input short-circuits.
Example: Comfort keypad connected to input X2
Long press (>500ms): open/close actuator, actuator runs to end stop
Short press:
X3 Input for automatic control.
Data:
3.1 Open
3.2 Close
3.3 GND / 0V
X3 must be controlled by a potential/volt free contact.
X3 has lower priority than X2.
X3 is blocked for 30 minutes after X2 has received a command (from production code 11BM03KW).
AUX, power supply for weather station, for example. See "X10" for a description of connection of rain/wind
X7
sensors.
Data:
7.1 24V
7.2 0V
Maximum 500 mA
Main power must be switched off, before connecting any kind of external equipment to X7!
Connected consumption must be included in the controller's total load, which must mot exceed 3A.
