For use with our SPD control cabinets, we recommend the ZSP-5 level signaling set consisting of:
- Float level switch, so-called Float – 5 pcs. (10 m cables)
- Ø3 DIN 763 stainless steel A4 chain – 1 pc. (4 m)
- Long Ø4 stainless steel A4 shackle – 2 pcs.
- Ø10 stainless steel A2 hook – 1 pc.
- Cast-iron chain weight – 1–2 pcs.
- Upper Alarm float – signals that the permissible wastewater level in the tank has been exceeded and activates the optical signal on the control cabinet housing.
- Start 2 float – corresponds to the upper operating level in the pumping station at which the standby pump is switched on. The Start 2 float switches on when it is in the raised position.
- Start 1 float – corresponds to the upper operating level in the pumping station at which the first pump is switched on. The retention level in the tank is regulated by the distance between this float and the Stop float; note that the Start 1 float switches on when it is in the raised position.
- Stop float – corresponds to the lower operating wastewater level in the tank at which the pumps are switched off. The suspension level should be set according to the pump manufacturer's guidelines. The Stop float operates only in the lowered position.
- Lower Dry-Run float – protects the pump against overheating and air ingress.
NOTE! The working length of the floats should be at least 15 cm due to the stiffness of the cable in wastewater.
