Valve monitoring function
According to the EN 12566-3 European standard, the function of all parts that are necessary for a proper function of the plant have to be monitored. This standard is the base for any CE marks on sewage treatment plants sold in the European union. The Sequetrol® starter plus now offers a reliable, self-learning monitoring for solenoid valves. This is realized by the accurate, in-build pressure sensor. The control unit will detect both, a valve that does not open and a valve that does not close. Even if two 3/2 valves are operated.
“Cash-Lock” function to enhance payment behavior
Most customers pay in time - but some don’t. If you want to avoid time and trouble solving these issues, you can use the so-called “Cash-Lock” function. If no payment is received, the control unit stops the plant after a predefined number of days. As soon as you receive payment, you send the customer a unlock PIN . If the unlock PIN is entered within the due date, the control unit won’t stop the plant. Simple and efficient!
Output timing parameters and ECO-modes
To save blower runtime and thus energy, it’s possible to distinguish between reduced, normal and holiday 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 the absence can be entered to keep the ECO-mode active during this period.
The full menu structure is adaptable according to your needs.
Some examples: It’s up to you if the serviceman can delete the operating hours of the particular outputs. You decide if the end customer can operate the outputs manually. Do you want to allow servicemen to change the ON/OFF times of the outputs?
Like this, every sewage treatment plant manufacturer will get the control unit he needs.
The Sequetrol® starter plus contains a detailed event log, that stores the events together with the time & date of the occurrence, the in- and output state and the measured pressure.
The logged events are: Mains failure, low battery, high water level (via float switch and digital input), low and high pressure, valve function (opening and closing), and Cash-Lock.
