iPWM/LIN
connection
Installation and operating instructions Wilo-Para
Connecting the iPWM/LIN signal cable (accessories)
• Connect the signal cable plug to the iPWM/LIN
connection (11) until it snaps into place.
iPWM:
• Cable assignment:
1 brown: PWM input (from controller)
2 blue or grey: Signal earth (GND)
3 black: PWM output (from the pump)
• Signal properties:
- Signal frequency: 100 Hz – 5000 Hz
(1000 Hz nominal)
- Signal amplitude: Min. 3.6 V at 3 mA to 24 V
for 7.5 mA, absorbed by the pump interface.
- Signal polarity: yes
LIN:
• Cable assignment:
1 brown: 12 V DC to 24 V DC (+/-10 %)
2 blue or grey: Signal earth (GND)
3 black: LIN bus data
• Signal properties:
- Bus speed: 19200 bit/s
CAUTION!
The connection of mains voltage (230 V AC) to the com-
munication pins (iPWM/LIN) will destroy the product.
• At the PWM input, the maximum voltage is 24 V
pulsed input voltage.
