Automatic burner control DGAI. 131F Dungs with ignition control for gas burners without blower
- These automatic burner controls DGAI. 131F are designed for ignition control for gas burners without fan for intermittent operation with capacities up to 350 kW. Suitable especially for direct ignition or stainless steel burners.
- Flame detection by ionization.
- Program sequence control by electronic timers.
- Electronic ignition with ignition transformer DZÜ 2.
- Ignition and flame monitoring with common electrode or with separate ignition and ionisation.
- Classification EN 298 AMLLXN.
- Note: This series is no longer part of the Dungs main product line.
Functional description DGAI. 131F
When the regulator receives a heat request, voltage is applied to the gas solenoid valve and the ignition control generates sparks via the DZÜ 2 ignition transformer. The ignition switches off
immediately on receipt of the flame message. If no flame is generated during the safety interval of 5 seconds (SZA), fault interlock is performed. If a flame occurs when the regulator is switched
on, the program sequence is blocked. On flame loss during operation, the gas valve is switched off within 1 second (SZB).
Fault release: By means of an integrated button or externally via NOC from terminal 7 to N.
Ignition and flame detection using DZU 2
The ignition control system is integrated on the PCB. Approximately 5 ignition sparks are created per second at 200 V by capacitor discharge via a thyristor on the primary coil of the ignition
transformer. This is increased to 10-15 kV by the ignition transformer. Plug the DZU 2 directly into the electrode which carries out ignition and flame detection. Due to the direct connection
between the ignition transformer and the ignition electrode, no high-voltage cable is required. Line loss and radio interference are minimized. The DGAI. 131F can be operated with separated
ignition and monitoring electrodes for end-point monitoring. Tie the black wire of DZU 2 to ground and connect the monitoring electrode to terminal 8.
