SPIDER - A Universal Pump Control

A universal control, with many applications. SPIDER pump control can control several pumps with alternating operation, with only one level switch connected. On the same level switch, a high level or defective pump function can also be alerted.

SPIDER pump control can also be connected to a standard pressure transmitter or other level meter with 4-20mA signal with optional measuring range. With analog level signal connected, SPIDER can perform a valid pump flow calculation that has not been seen before, and based on this function, the need for pump service can be predicted.

SPIDER GPRS modem with “FAST RESPONS” function

SPIDER pump control comes as standard with a built-in modem with multi-protocol, which automatically detects whether Modbus or Comli is communicated via the SCADA-system.

All SPIDER registers are of the same data type, so only one telegram needs to be transmitted to get updated data. The SPIDER GPRS modem includes the “FAST RESPONS” function and is designed to support future IoT requirements. SPIDER can be delivered with both 2G and 4G modems. SPIDER has a built-in powerbank, so no need for external battery backup in case of power failure.

  • Advanced 1- and 2-pump control, where faulty pump is automatically taken out of operation.
  • Built-in GSM / GPRS modem with “FAST RESPONSE” (available in two variants 2G or 4G)
  • Multiprotocol, Modbus & Comli. SPIDER even detects what the SCADA system uses.
  • 288 local logs per analog input, with freely defined time interval in seconds
  • Status word with counter function for errors / alarms
  • Connection of a graphical 2.4 ”OLED display, which is“ clicked ”directly on the SPIDER
  • Connection of HMI 7 ”graphic color touch display, via serial HMI interface.
  • Validated flow calculation, where the pumps’ “true” capacity is calculated, also for parallel operation
  • Inlet flow calculation showing the inlet profile to the pump station
  • Emergency control function via level rocker if the pressure transmitter is faulty.
  • Pump service indication, where SPIDER tells when the pump is to be serviced due to reduced capacity
  • Built-in power bank, for alarm in case of voltage failure – no external battery.
  • Function for overflow calculation with number, duration and quantity indication
  • Function for daily exercise of pump so that it does not get stuck during prolonged downtime
  • Function for daily depth pumping, so possibly. floating layers can be avoided
  • Possibility of varied starting level, so that fat build-up is avoided
  • Communication with frequency converter via Modbus (Danfoss FC202, Schneider Altivar Process and ABB)
  • Communication with Siemens MAG6000 flow meter via Modbus
  • Communication with energy measures via Modbus for KWh, Cosphi, Amp, Volt data for SCADA.
  • Connection of SPIDER – I / O module, with even more inputs and outputs
  • Configuration of SPIDER via Danish AcowaZoo PC software

The SPIDER Pump Control is very flexible and can be used in many different applications, such as:

  • Control of Pumping stations
