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 not exceed 6A.
X9
Solid state output, for transmission of fault signal
Data:
9.1 Fault – Open contact = Fault, Closed contact = OK
9.2 Fault – Open contact = Fault, Closed contact = OK
Data
Max. voltage: 30 Vp (peak)
Max. current: 150 mA
Typical On- resistance: 15Ω
Max. On-resistance: 18 Ω
Max. switching speed: 2 ms
X10
Connecting wind / rain sensors of type WLA 330 or WLA 331.
Wind / rain sensor must be connected on both X10 and X7.
Data:
10.1 Common Open
10.2 Common Close (Rain)
10.3 GND / 0V
X10 has highest priority over X2/X4 and X3/X5.
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 of approx. 1mA (min. 0.9mA, max. 1.1mA)
Connecting wind/rain and rain sensor
WLA 330 and WLA 331– the sensors settings are set on the sensor.
DIP switches 1-3 on WLA 330 must be set in relation to windspeed tolerances. See the guideline for WLA 330 for
DIP switch settings.
