Frequently Asked Questions - App comando Bruciatore G2.22 R LX SIME

What is the App comando Bruciatore G2.22 R LX used for?

The App comando Bruciatore G2.22 R LX is a microcontroller-based oil burner control designed for startup, supervision, and control of forced draft oil burners, suitable for 1- or 2-stage intermittent operation with oil throughput up to 30 kg/h (standard) or above.

What flame detectors are compatible with this burner control?

It works with photoresistive detectors QRB... for yellow-burning flames and QRC... for blue-burning flames. Minimum required detector current with flame is 45 μA, and maximum without flame is 5.5 μA.

What is the power supply requirement?

Mains voltage can be AC 230 V +10%/-15% or AC 120 V +10%/-15% at 50 to 60 Hz (±6%). Power consumption is 12 VA.

How do I reset the burner control after a lockout?

Press the lockout reset button for about 1 second (less than 3 seconds). The control can be reset immediately only when all line contacts are closed and no undervoltage exists.

What does the multicolor LED indicate during operation?

Green steady = flame OK in operation; Green flashing = flame not OK; Yellow = oil preheater on; Flashing yellow = ignition phase; Red steady = lockout; Red flashing (with code) = cause of fault.

How can I diagnose the cause of a lockout?

After lockout (red LED steady), press the reset button for more than 3 seconds to enter fault diagnostics. The LED will blink a red code (e.g., 2 blinks = no flame at end of safety time). Refer to the error code table in the manual.

What is the designed lifetime of this burner control?

The designed lifetime is 250,000 burner startup cycles, which corresponds to approximately 10 years under normal heating conditions. After reaching this limit, the control must be replaced by authorized personnel.

Can I use this control with an oil preheater?

Yes, it has a bridging contact for oil preheater and monitors the preheater time. If the preheater's release contact does not close within 10 minutes, the burner control will initiate lockout.

What safety checks should be performed during commissioning?

Perform these checks: (a) Darken flame detector – lockout at end of safety time; (b) Expose detector to extraneous light – lockout within 40 s; (c) Simulate flame loss during operation – repetition followed by lockout after 3 attempts.

What are the environmental operating conditions?

For LMO14/24: temperature -5...+60 °C; for LMO44: -20...+60 °C. Humidity <95% r.h. Condensation, ice, and water ingress are not permitted. Storage and transport: -20...+60 °C.

Function

Preconditions for startup	Burner control is resetReset button «EK1» or «EK2» not usedAll contacts in the line are closed and there is demand for heatNo undervolt ageF lame detector is darkened and there is no extraneous light
Undervoltage	Safety shutdown from the operating position takes place should mains voltage drop below about AC 165 V (UN = AC 230 V) or AC 75 V (UN = AC 120 V)Restart is initiated when mains voltage exceeds about AC 175 V (UN = AC 230 V) or AC 95 V (UN = AC 120 V)
Time supervision oil preheater	If the oil preheater's release contact does not close within 10 minutes, the burner control will initiate lockout.
Controlled intermittent operation	After no more than 24 hours of continuous operation, the burner control will initiate automatic controlled shutdown followed by a restart.
Control sequence in the event of fault	If lockout occurs, the outputs for the fuel valves, the burner motor and the ignition equipment will immediately be deactivated (<1 second). In the event of lockout, the LMO... remains locked and the red signal lamp (LED) will light up. The burner control can immediately be reset. This state is also maintained in the case of mains failure.
	Cause	Response
	Mains failure	Restart
	Voltage has fallen below the undervoltage threshold	Safety shutdown, followed by restart
	Extraneous light during prepurge time (t1), 5 s before fuel valve (BV1) release	Lockout at the end of prepurge time (t1)
	Extraneous light during waiting time (tw)	Prevention of startup, lockout after 40 seconds at the latest
	No flame at the end of safety time (TSA) Lockout at the end of safety time (TSA), blink code 2
	Loss of flame during operation	Max. 3 repetitions, followed by lockout
	Oil preheater's release contact does not close within 10 minutes	Lockout
Resetting the burner control	When lockout occurs, the burner control can immediately be reset. To do this, press the lockout reset button for about 1 second (<3 seconds). The LMO... can only be reset when all contacts in the line are closed and when there is no undervoltage.
Ignition program with LMO14.113x2 and LMO24.113x2	If the flame is lost during safety time (TSA), the burner will be reignited, but only until the end of safety time (TSA). This means that several ignition attempts can be made during safety time (TSA) (see Control sequence).
Limitation of repetitions	If the flame is lost during operation, a maximum of 3 repetitions can be made. If the flame is lost for the fourth time during operation, the burner will initiate lockout. The repetition count is restarted each time controlled switching on by control thermostat or pressurestat (R) takes place.

Operation, display, diagnostics

Operation

Lockout reset button «EK» is the key operating element for resetting the burner control and for activating / deactivating the diagnostic functions.

The multicolor signal lamp (LED) in the lockout reset button is the key indicating element for both visual diagnostics and interface diagnostics.

Both «EK» and LED are located under the transparent cover of the lockout reset button.

There are 2 diagnostic choices:

1. Visual diagnostics: Operational status indication or diagnostics of the cause of fault.
2. Interface diagnostics: With the help of the interface OCI400 and PC software ACS400 / ACS410 or flue gas analyzers of different makes.

Visual diagnostics:

In normal operation, the different operating states are indicated in the form of color codes according to the color code table given below.

Operational status indication

During startup, status indication takes place according to the following table:

Diagnostics of the cause of fault

After lockout, the red signal lamp (LED) remains steady on. In that condition, the visual diagnostics of the cause of fault according to the error code table can be activated by pressing the lockout reset button for more than 3 seconds. Pressing the reset button again for at least 3 seconds, the interface diagnostics will be activated. Interface diagnostics works only if the AGK20... lockout reset button extension is not fitted. If, by accident, interface diagnostics has been activated, in which case the slightly red light of the signal lamp flickers, it can be deactivated by pressing again the lockout reset button for at least 3 seconds. The instant of switching over is indicated by a yellow light pulse.

The following sequence activates the diagnostics of the cause of fault:
