Sequetrol starter

• Outstanding price-performance ratio
• World first self-learning membrane blower monitoring and protection by power monitoring (no pressure measurement needed to monitor the pressure high / low levels of a membrane blower)
• Suitable for fixed-bed, vortex floating-bed and continuous sewage treatment plants
• Pulsed blower operation helps to save energy compared to 24 / 7 operation
• Special eco-mode can be easily activated during night / weekend / holiday
• Menu structure adaptable to customer needs
• Acoustic mains failure alarm according to special German requirements
• Installation and connection possible without opening the casing
• optional 2/4G - SMS alarm forwarding

The Sequetrol^® starter is designed as a highly comfortable and adaptable Control Unit with the price of an entry level device. The unique blower monitoring and protection function as well as adjustable timing parameters for the particular outputs, qualify the starter as a perfect Control Unit for fixed bed and floating vortex bed plants.

Blower monitoring and protection function

Monitoring blower functionality is critical for any Sewage Treatment plant operator, as the blower serves as the core component of the system. In the event of diffuser or tubing blockages, early detection allows the operator to shut down the blower proactively, potentially preventing damage and reducing maintenance costs.

Normally a small tube must be installed between an expensive pressure sensor and the air hose of the blower to monitor the pressure and the blower. Sequetrol^® starter does not need this installation as it monitors the energy consumption of the particular membrane blower, learns its “fingerprint” and thus detects any malfunction or overload of the blower.

Output timing parameters and ECO-modes

The ON and OFF times for each output can be preset and later changed in the menu. Several outputs can be coupled for sludge removal: In this case the blower will be switched on when the valve to the sludge removal is open. Another option is to activate the second (e.g. sludge) output at a certain time, for example at 6 am and 11 pm.

To save blower runtime and thus energy, it’s possible to distinguish between reduced and normal load. For example, during holidays or weekends the blower ON times can be reduced. This ECO-mode can be programmed for nighttime or weekends respective weekdays. Moreover, for holidays the length of absence can be entered to keep the ECO-mode active during this period.

Menu structure

The menu structure is flexible to meet your needs. For instance, you may configure, whether the serviceman can delete the operating hours of outputs, if manual control of outputs is enabled for end-user accounts or whether serviceman can modify ON/OFF time parameters of the outputs.

Outputs and Inputs

The Sequetrol^® starter is equipped with three outputs and one digital input. The blower output is led out to the mains socket. Thus, the blower can easily be connected by end customers. The valve output can be connected by a screw-type terminal inside the plant and lead out through a cable grommet. The third output is a low-voltage (5VDC) alarm output suitable for our BonFlash alarm lamp or BonAlarm alarm forwarder.

Moreover, one alarm float switch can be connected. Thus, flooding of the tanks can be detected.

Standard models are available in any quantity. Please consult the Order Reference table for standard models. Besides the standard models, customer specific versions / configurations are available at an MOQ of 100 units per year. Please refer to the Order Reference table for customer specific models.

On request and at reasonable quantities, customer specific Control Units based on Sequetrol starter^® can be derived. For example, another casing, a different I/O configuration, another electric socket type or no electric socket, other communication technologies like LoRa^® and similar changes can be performed.
