Kromschroeder IFD258-3/1Q (84621410) burner control unit

Krom schroder IFD258-3/1Q 84621410 automatic burner control unit ignites and monitors directly ignited industrial gas burners of unlimited capacity. As a result of its fully electronic design it reacts quickly to various process requirements and is therefore also suitable for frequent cycling operation.

Kromschroder 84621410 IFD258-3/1Q gas burner safety control box can be used for atmospheric burners or forced draught burners in multiple burner applications, where a central control system is used for pre-purge and for monitoring. The burners may be modulating or stage-controlled.

Kromschroeder IFD258-3/1Q 84621410 gas burner control box is suitable for operation in grounded and ungrounded systems.

The program status and the level of the flame signal can be read directly from the unit. The switch-off threshold can be set using a potentiometer.

The behavior in the event of flame failure during operation can be selected using a switch. Either an immediate fault lock-out or a restart occurs.

Kromschroder 84621410 IFD258-3/1Q burner control wiring

1. Kromschroder 84621410 IFD258-3/1Q automatic gas firing device is suitable for hard wiring only. Do not reverse phase and neutral conductor. Different phases of a three-phase current system must not be installed at the IFD.
2. No voltage may be connected to the valve and ignition outputs.
3. Do not use unused terminals as support terminals.
4. The signalling contacts for operating and fault signals do not meet the requirements for safety extra low voltage (SELV/PELV).
5. The burner should be adequately grounded. Incorrect wiring and an insufficient ground connection can cause damage to the equipment during single-eletrode operation.
6. In the case of single-electrode operation, only ignition transformers of type TZI or TGI may be used. The use of pulse-spark or high-frequency ignition devices is not permitted.
