Page 64: Valve Proving
7.5.2 Valve proving Valve proving is active only when firing on gas. Valve proving designed to detect leaking gas valves and, if necessary, to prevent the valves from opening or ignition from being switched on. Lockout is initiated, if required. When making the valve proving test, the gas valve on the burner side is opened first to bring the test space to atmospheric pressure.
Page 65: Valve Proving With Separate Pressure Switch (P Lt) X9-04
Caution! The OEM must set the evacuation, filling and test times for atmospheric or mains pressure on every plant in compliance with the requirements of EN 1643. It must be ensured that the 2 test times are correctly set. It is to be checked whether the gas required for the test may be fed into the combustion chamber (on the relevant application).
Page 66: Valve Proving Via Gas Pressure Switch-Min X5-01
7.5.4 Valve proving via gas pressure switch-min X5-01 Step 1: t80 – evacuation of test space. P LT (Pmin) Gas valve on the burner side is opened to bring the test space to atmospheric pressure. Step 2: t81 – atmospheric pressure test. When the gas has closed, the gas pressure in the test space must not exceed a certain level.
Page 67: Safety Phase (Phase 02)
7.5.4.2. Safety phase (phase 02) The safety phase is an intermediate phase which is completed prior to triggering lockout. The relays of the fuel valves and the safety relay (fan) are deenergized, but lockout does not yet take place. The alarm relay is not yet activated. If possible or permitted, safety checks or repetition counter checks are made whose results decide on the transition to Lockout phase or Standby.
Page 68: Special Functions During The Program Sequence
7.5.5 Special functions during the program sequence 7.5.5.1. Reset / manual lockout The system can be manually locked by simultaneously pressing the Info button and any other button on the AZL2... This function enables the user to interlock the system from any operating level, that is, to trigger unalterable shutdown.
Page 69 Resetting by pressing the button by the Reset connection terminal on the LMV36... basic unit (X8-04, pin 1) If the unit is in the lockout position, a reset can be made by pressing the button for 1…3 seconds. Longer or shorter pushes on the button are ignored so that the system maintains the lockout position.

Page 71: Repetition Counter
7.5.5.4. Repetition counter Repetition counters are available for different types of errors. They are used to set the number of errors permitted until lockout occurs. The last error initiates lockout. When setting the number of errors to 3, for example, a repetition (restart) takes place after the first 2 errors, and after the third error, the system initiates lockout.

7.5.5.5. Start without prepurging (as per EN 676) When using valve proving and 2 fuel valves of class A, prepurging is not required (conforming to EN 676). Prepurging can be deactivated via parameter. Parameter Gas: Prepurging 0 = inactive 1 = active Fuel 1 gas: Prepurging 0 = inactive 1 = active...
Page 74: Gas Shortage Program
7.5.5.6. Gas shortage program Valve proving via gas pressure switch-min (parameter 236 = 2) Since gas pressure switch-min is not located between the fuel valves, the gas shortage test cannot be made in phase 22. Therefore, when performing valve proving on startup, the gas shortage test is made at the end of the filling time (end of phase 82).

Page 76: Continuous Fan
7.5.5.10. Continuous fan With burners that can be damaged by heat (e.g. several burners using the same combustion chamber), continuous purging may be required. In that case, the fan operates continuously in all phases. For that purpose, the fan motor contactor is to be connected to X3-05, pin 3, tapped after the unit fuse and the safety loop.
Page 77: Test Function For Burner Approval - Loss-Of-Flame Test (Tüv Test)
7.5.5.11. Test function for burner approval – loss-of-flame test (TÜV test) The purpose of this test is to verify the detection time required in the event of loss of flame when applying for burner approval. When starting the test, the fuel valves are shut to determine the time (resolution of 0.2 seconds) until the basic unit detects loss of flame.

Page 109: Electronic Fuel-Air Ratio Control
Electronic fuel-air ratio control 11.1 General Electronic air-fuel ratio control is used to control the burner’s actuators depending on burner output. It is possible to connect 2 actuators and, optionally, 1 VSD. Resolution is 0.1° with the actuators and 0.1% with the VSD. Output can be regulated in increments of 0.1% in modulating mode or with a maximum of 3 stages in multistage mode.
Page 110: Prepurging
11.2.3 Prepurging This position is approached in phase Traveling to prepurging (24). The position can be set via the following parameters: Parameter Actuator 501.01 No-flame positions fuel actuator: Prepurge position 502.01 No-flame positions air actuator: Prepurge position 503.01 No-flame speeds VSD: Prepurge speed 504.01 Fuel 1: No-flame positions fuel actuator: Prepurge position 505.01...
Page 111: Modulating Operation
11.3 Modulating operation In modulating mode, it is possible to operate 2 actuators and 1 VSD. The burner‘s output can be regulated between 20.0% (low-fire) and 100.0% (high-fire) in increments of 0.1%. Since the actuators are never allowed to operate simultaneously, the output is increased in small steps of 1%.
Page 112: Traveling Speed/Maximum Curve Slope
11.3.2 Traveling speed/maximum curve slope The time required to modulate from low-fire to high-fire can be set via parameter 544. In connection with the actuator’s ramp in the basic unit, the following positioning angles or speed changes between maximum 2 curvepoints can be covered: Modulation Modulation Modulation...
Page 113: Entering The Running Position
Between the ignition time (P0) and the low-fire point (P1), a speed differential of up to 40% can be set for the VSD, independent of the selected ramp. This means that the period of time from ignition to low-fire can vary between 4…32 seconds (5...40 seconds ramp).
Page 114: Limitation Of Modulation Range
11.3.5 Limitation of modulation range If the modulation range shall be further restricted from 20 to 100% against the defined curve, 4 parameters are available to define a new low-fire and high-fire position. Parameter Lower output limit undefined = 20 % Fuel 1: Lower output limit undefined = 20 % Upper output limit...
Page 115: Setting The Minimum And Maximum Output
11.3.6 Setting the minimum and maximum output For changes regarding setting of the minimum and maximum output after the curve settings, note the following: After leaving the curve settings with completely defined curvepoints, proceed in modulating operation by setting the minimum / maximum output (parameters 546 / 545 or 566 / 565).
Page 116: Multistage Operation
11.4 Multistage operation This operating mode is only available when firing on oil. There is a choice of 2-stage and 3-stage operation. Hence, the burner’s output can be modulated via 2 or 3 stages. Modulation is accomplished by adjustment of the air actuator or the VSD and by switching the fuel valves for adjusting the amount of fuel.
Page 117: Adjustment Of Output
11.4.3 Adjustment of output When the output increases, the system moves from the curvepoint of stage 1 (P1) to the switch-on point of stage 2 (P2on). If the switch-on point is exceeded, the valve for the second stage is switched on. Then, the system moves to the curvepoint for stage 2 (P2). When the output decreases, the system moves from the curvepoint of stage 2 (P2) to the switch-off point of stage 2 (P2of).
Page 118: Limitation Of Modulation Range
11.4.6 Limitation of modulation range If the modulation range for stage 1 and stage 2, or stage 3, shall be further restricted, 4 parameters can be used to define a new low-fire and high-fire position.

When mounting the actuators, it must be made certain that the mechanical link to the controlling elements is form-fitted! LMV...
Page 121: Referencing
12.3 Referencing An incremental transducer is used for position feedback. This means that referencing of the actuators must be performed after power-ON. In addition, at the end of each shutdown in phase 10, the actuators are referenced to ensure that individual stepping errors, which could lead to shutdown, do not accumulate.

Tolerance limit of position monitoring (0.1°) Index 0 = fuel Index 1 = air...
Page 123: Reference Run
12.3.1 Reference run Different reference runs are made to unambiguously determine the actuators’ permissible working range. This means that, in the event of a power failure during referencing, the actuator is prevented from travelling to a range outside the optical feedback system or from running against a mechanical stop.
Page 124 Example of actuator with counterclockwise rotation: When referencing in the CLOSED position, the actuator first travels a certain distance into the working range (toward the OPEN position). Then, it travels to a position representing maximum -7.7°, thereby crossing the reference mark for the fist time. Then, the actuator moves in the other direction again and detects the inner ramp of the reference mark.
Page 125: Direction Of Rotation
12.4 Direction of rotation With the SQM3…actuator, the direction of rotation can be selected on an individual basis. Parameter 602.00 Actuator's direction of rotation Index 0 = fuel 0 = counterclockwise 1 = clockwise (exclusively for SQM3...) 602.01 Actuator's direction of rotation Index 1 = air 0 = counterclockwise 1 = clockwise (exclusively for SQM3...)
Page 126: Monitoring The Actuator Positions
12.5 Monitoring the actuator positions To monitor the actuator’s current positions, an optical incremental transducer with a resolution of 0.7° is used. The correct position of the drive shaft is ensured by comparing the motor steps made with the position obtained from the incremental transducer.

Page 128: Changing The Error Detection Band For Monitoring The Actuator Positions
12.6 Changing the error detection band for monitoring the actuator positions The error detection band can be changed via parameter 606 or 610. A change is to be made only when using SQN13.17… or SQN14.17… actuators which, due to their mechanical design, require greater tolerances. For these types of actuators, set parameter 606 or 610 to 2.2°.
Page 129: Protection Against Mixup Of Actuator
12.9 Protection against mixup of actuator Mixup of actuators can be detected through appropriate installation (using different reference marks for the air and fuel actuator: OPEN / CLOSED / 0° / 90°). With at least one of the actuators, the reference mark not used must be blocked by a mechanical stop.
Page 130: Fan Control
13 Fan control 13.1 Function principle Optionally, the LMV36... system can be operated with a VSD or PWM fan. Control is accomplished via a DC 0…10 V interface. For control of the fan’s speed, a safety- related speed feedback signal is required. With pneumatic fuel-air ratio control, the speed feedback signal is not evaluated.
Page 131: Vsd Control X74 Pin 3
To enable the VSD to bring the fan motor’s speed to the correct no-load speed, the motor contactor’s drop out delay time must be about 25 seconds. Example: Siemens Micromaster 440 +24 V Setpoint 0...10 V Figure 82: Connection of VSD to the LMV36 It is possible to set the VSD control to 0 via the analog output when the safety loop is open (including burner flange switch).

Page 133: Acquisition Of Speed
13.7 Acquisition of speed 13.7.1 Acquisition of speed with proximity switch The actual speed is acquired by an inductive proximity switch which scans a metal sensor disk. The sensor disk must be attached directly to the motor’s drive shaft. Speed acquisition is safety-related.
Page 134: Acquisition Of Speed With Hall Generator
Speed sensor Figure 84: Speed sensor Selection of fan motor Motor supplier: Selection of a motor with threaded hole M8 x 15 at the end of the fan motor’s drive shaft. Standard motor and machining (drilling hole and cutting thread M8 x 15). 13.7.2 Acquisition of speed with Hall generator If the speed is acquired via a Hall generator, the requirements for safety-related applications are the same as those for the speed feedback signal via sensor disk.
Page 135: Speed Control
13.8 Speed control The LMV36... controls the fan motor’s speed to the setpoint. To ensure that the speed can still be increased when the maximum speed is reached, the speed is standardized when the motor is controlled at 95%. Hence, with a speed setpoint of 100%, a speed increase of 5% is still possible.
Page 136: Speed Supervision
13.9 Speed supervision The fan’s current speed is acquired by the LMV36... and assessed from a safety point of view. If the fan does not operate at the speed setpoint, speed control makes a corrective action, trying to reach the setpoint. If it is not reached within a certain period of time, safety shutdown is initiated.
Page 137: Setting The Parameters Of The Vsd
13.10 Setting the parameters of the VSD If a control signal of 95% (9.5 V) is not sufficient for the burner to deliver its rated capacity, you can proceed as follows: Set the maximum frequency to 105.3% of the motor’s rated speed In the case of a motor frequency of 50 Hz, this means: Set the maximum frequency of the VSD to 50 Hz x 1.053 = 52.6 Hz (on the VSD).
Page 138: Standardization Of Speed
13.11 Standardization of speed Since the different types of fans operate at different speeds and signal handling should be as straightforward as possible, all speeds in the system are standardized between 0 and 100%. For this reason, the VSD module uses a parameter which contains the Standard speed (100% speed).
Page 139 Close the standardization When standardization is successfully completed, reset parameter 641 to 0. If standardization was not successful, parameter 641 assumes a negative value. The value provides information on the cause of fault: Value Error Remedy Timeout at the end of standardization during ramp down Timeout of standardization (VSD ramp down of the VSD time too long)
