Signal cable connection

Connector is designed as an AMP Mini Superseal 3P CA (external view of the pump
connection)
84
Assignment
Live wire (L)
Protective earth conductor PE
Neutral conductor (N)
Check the presence and integrity of the seal on the connector before installa-
tion.
Connect the cable plug to the mains power socket (Fig. I, Item 13) until it snaps
into place.
Ensure that the connecting cable does not contact either the pipes or the pump.
Exclusively connect the power supply to 230 V (phase to neutral conductor)!
Signal frequency: 90 Hz – 5000 Hz (1000 Hz nominal value)
Signal amplitude: Min. 4 V at 3.5 mA to 24.5 V for 10 mA, absorbed by the pump
interface
Signal polarity: yes
Electric strength 30 V DC/24 V AC
Input resistance of the voltage input > 10 kΩ
Bus speed: 19200 bit/s
