- Power consumption: approximately 12 VA.
- Working environment: liquid fuel.
- Operating mode: intermittent.
- Operating temperature: -5ºC...+60ºC.
- Purge duration: 16 seconds.
- Safety time: 10 seconds.
- Time before ignition: 15 seconds.
Device and комплектация
The burner manager has a compact, detachable design that attaches to the base with a latch. The body material is heat-resistant, durable plastic. Protection of electrical components according to IP 40 standard is provided by installation.
The device includes an electronic flame signal amplifier, relays, a microcontroller controlling the command sequence.
A convenient button with a built-in multi-colored indicator is located on the front panel for locking/unlocking the device. A flashing lamp indicates emergency situations. A three-color LED and a special well-thought-out coding system make it easy to identify the causes of failures. The button has a socket for an interface adapter or extension cable connection.
Flame memory control
Siemens provides flame combustion control, working in conjunction with a photoresistive QRB sensor (yellow flame) and a blue flame QRC sensor (oxidizing flame).
Functionality and features:
- Remote reset (restart) of the automation is possible;
- Instant (less than 1 second) shut-off of fuel supply when the lock is activated;
- Recognition of low voltage in the network, shutdown when the minimum limit (165 Volts) is reached with subsequent automatic start-up when network parameters are restored;
- Availability of a shunting contact for the heating element;
- Fuel heater timing control function;
- Accurate execution of program commands thanks to digital signal processing;
- Controlled automatic restart of the automation every 24 hours of operation;
- Limited number of repetitions (no more than 3 starts) within a single controlled start;
- Convenient system for reporting current operation and emergency failures using a three-color lamp or software.
