  • Up to 8 + 1 relay outputs
  • Individually equipped according to customer requirements
  • Multi-language menu
  • GSM-module as option

Why use the Sequetrol control unit?

  • Water-level control without expensive and unreliable float switches means no more electricity carrying parts in the cesspool.
  • Reliable technology proven in thousands of sewage treatment plants
  • Up to 8 + 1 relay outputs (8 x 230VAC, 1 x low voltage) for an easy connection of accessory devices
  • Event protocol with event, date & time and program step
  • Individually equipped according to customer requirements
  • Sequence program can be easily created and modified with the PC software MenuMaker 2
  • Password protected operating levels
  • Updateable firmware and software
  • Rechargeable batteries for mains failure alarm

Water-level control

The innovative water-level sensing by pressure measurement allows cost-effective detection of pre-set water levels without the use of failure-prone float-switches.

State machine

The Sequetrol® control unit is especially suited for sophisticated SBR control algorithms with normal and eco mode and multiple programs for different numbers of inhabitants or different plant types. The programs can be chosen on-site. This can help to reduce the number of different control units on stock.
The program can be triggered by the daytime, so day / night mode or similar is possible.
The Sequetrol® has an in-build memory for event logs and for an electronic operating book. The operating book will store basic information about the regularly performed owner maintenance checks. The event logs as well as the electronic operating book can be transferred from the Sequetrol® to a PC using a special memory key.
The menu is prepared for up to five languages. The languages can be switched on-site.
The menu access can be restricted in up to three different access levels (user, service, admin).

Interfaces and connectors

The optional analogue input can be used for a further optimization of the wastewater treatment process. Properties, such as the turbidity of the treated water can be analyzed.
Up to four external digital signals can be monitored and processed within the control algorithm.
Up to 8 relay outputs for 230VAC offer a comfortable connection of solenoid valves, diaphragm blowers, submersible pumps or other loads.
The optional GSM module can be used to monitor the plant together with the BONNEL Aquavisor® telemetry server.
All electrical connections are made using reverse polarity protected plugs with IP54 rating. Of course the type of connectors can be changed according to customer requirements.

Equipment

The extent of the system functionality and the design of the front panel of the Sequetrol® control unit can be tailored to match your individual needs.
The Sequetrol® control unit is equipped with features as acoustic signaling of predefined conditions, rechargeable batteries to signal mains failure and non-volatile EEPROM memory for programs, event logs and an electronic operating book.
