    Important safety instructions Read and follow the operating instructions and safety instructions carefully before starting operations! All modifications must be done by qualified technicians! Warns that failure to observe the precaution may cause electric shock Warns that failure to observe the precaution may cause personal injury or damage to property.
  • Page 7 All work, carried out at opened HYDROVAR, may only be performed by qualified and authorized staff. Furthermore, care must be taken not to short circuit the neighbouring components when connecting the external control wires and all cable ends which are not in use are isolated. The HYDROVAR contains electronic safety devices which switch off the control element in the event of faults, whereby the motor has zero current but remains energised and comes to a halt.
  • Page 8 Transport, Handling, Storage, Disposal: • Check the HYDROVAR immediately upon delivery/receipt of dispatch for damage or missing parts • The HYDROVAR unit must be transported carefully and by competent personnel. • Avoid serious impacts NOTICE! The use of the WEEE Symbol indicates that this product may not be treated as household waste.

  • Page 10: Product Overview

    Product Overview 3.1 Hardware Configurations The HYDROVAR Modul Concept consists mechanically of two main parts, the Power Unit and the Control Card. In its basic configuration (consists only of the Power Unit) the HYDROVAR can be used as “Basic Inverter” without the need of the Control Card. In that form the HYDROVAR can be used as a sequence pump in a multi pump system, but also as a simple soft starter for single pump applications.

  • Page 11: Cascade Relay

    3.2.3 Cascade Relay One pump is fitted with a HYDROVAR “Master Inverter” and up to 5 full speed slave pumps can be switched ON and OFF on demand. For this purpose an additional relay card with 5 relays is used in the “Master Inverter”. Each Relay can be activated or deactivated depending on how many pumps are connected.

  • Page 12: Cascade Serial

    3.2.4 Cascade Serial In this mode there are various possibilities to combine the different versions of the HYDROVAR, which will be explained on the following pages. In general each of the pumps is equipped with a HYDROVAR unit. All units are connected via the RS485 interface and are communicating via standard MODBUS-Format (fixed with 9600 Baud, RTU, N81).
  • Page 13 To increase the operating safety of such a system, also a second “Master Inverter” could be used: RS 485 extended up connection to 8 pumps Full-featured Possibility: Each pump is equipped with a “Master Inverter” RS 485 extended up connection to 8 pumps In this mode it is possible to run all pumps in multi-controller mode and synchronous mode as well!
