Page 33 Each plug is designed to connect one external device or a small group of external devices, such as gas valves, to the LMV5. This being the case, each group of plugs on the front of the LMV5 provide line voltage and grounds so that an additional terminal strip is not necessary.
Page 34 The sole purpose of the FE is for termination of low voltage cable shields. The FE is bonded to the Reference Ground through capacitors on the LMV5 circuit board with the exception of the CANBus where it is bonded directly.
Page 35 It is extremely important that the shield of the CANBus cable is properly terminated. The shield of the CANBus cable is terminated to the LMV5 by using a special strain relief, part number AGG5.110. This strain relief also has a wire that should be connected to the shield terminal on the LMV5.
Page 36 PLL52 Module) so that the entire shield has continuity with terminal X51.1 which is the shield connection on the LMV5. This is achieved by clamping the shield on both cable segments with the metal clamps provided on the cable entry of each actuator. Clamps for the CANBus shield are also provided on the PLL52 module.

Page 57 Section 4 Parameters Parameters Introduction 4-1 The Siemens LMV5 BMS has a number of parameters (settings) that can be adjusted to suit the wide variety of applications that exist in the burner / boiler and industrial heating market. These parameters are broken up into three main groups by password access.
Page 58 Typical Settings Although the LMV5 has many parameters that can be adjusted, most burners / boilers only need a few parameters adjusted to operate properly. If the burner / boiler has been shop tested, the number of parameters that must be adjusted is reduced even further.
Page 59 The LMV51 has many more capabilities than what is listed above, and the LMV52 has many more capabilities than the LMV51. In order to make its many features user friendly, an LMV5 Parameter worksheet was created. This worksheet is Section 4-2 and carries all pertinent information concerning the parameters of the LMV5.
Page 60 If attempted, memory can be permanently damaged. An AZL52 can be used on any LMV5, (LMV51, LMV52 ) with no problems. The parameter set that the LMV5 uses for operation is stored in the LMV5 itself. When a parameter is changed (via the AZL5 or ACS450), the actual change in memory (parameter set) occurs in the LMV5 and not the AZL5.
Page 61 Press Enter, and the parameter set will be written from LMV5(Z) to AZL5(Z). Note: The AZL5(Z) does not need to be blank. The BurnerID in the LMV5 will overwrite it. An LMV5 will always overwrite the BurnerID in the AZL5.
Page 62 Setting Fuel Trains A number of different fuel train options exist for the LMV5. There are several trains for gas and several trains for oil. The following schematics describe the various options available for parameters (FuelTrainGas and FuelTrainOil). For gas, Pilot GP2 is normally used. For Light Oil, LO w Gasp is normally used.

Page 66 Addressing SQM4 Actuators Before actuators can be operated by the LMV5 they must be addressed and the direction or rotation must be set if it was not previously set. Depending on direction of rotation and home position set in the LMV5, the actuator may rotate as soon as it is addressed.
Page 67 Note: Check rotation of ALL actuators BEFORE commissioning combustion curves. This includes the oil actuator BEFORE commissioning the combustion curves on gas. If the direction of rotation is changed for any actuator, ALL combustion curves (both fuels) MUST be deleted. LMV5 QSG Rev 4 Sec 4 Pg 11 www.scccombustion.com...
Page 68 After the special positions are set, the burner can be lit-off. Please see below for the recommended light off procedure. The LMV5 can hold the burner in the pilot phase (Interval 1, phase 44) as well as a number of other phases with the “Program Stop” function. See parameter worksheet under Params & Display >...
Page 69 On most new installations, the Fuel-Air ratio curves are not set by the burner OEM, and must be set at start-up. If this is the case, the LMV5 will automatically set Point 1 (low fire) to the ignition position that was previously set. Point 1 can be changed without changing the ignition position if a low fire different from ignition is desired.
Page 70 If points are deleted from an existing curve, the reverse of what was previously explained happens. Although not recommended, a curve could consist of two points. One point at low fire and one point at high fire. The LMV5 would simply draw a line between the two points and that would be the combustion ‘curve’.

Page 72 MaxTmeMod should be set to a high number (30 min) so that it has no effect. 3. Time based stepping start The LMV5 will be held at low fire until a certain time elapses, and then a step-up in load will be taken. This continues until the ThresholdOFF value is reached.

Page 74 Special Features In addition to the capabilities mentioned above, the LMV5 also has many special settings that are very useful in some situations. These special settings are detailed in the next section, section 4-2. This section details the special settings (parameters) that are used most frequently. These are: NumFuelActuators Permits the LMV5 to run dual fuel with a single actuator.

Page 127 1) The wiring on the AGG5.210 transformer, specifically how the four pin connector X52 is wired to the LMV5. Most problems occur on Pins 3 and 4 of the transformer. Pin 3 on the transformer and terminal X52.4 on the LMV5 should be wired to PE (Protective Earth or Panel Ground).
Page 128 The second largest category of wiring problems concerns the grounding and the shielding of LMV5 components. The LMV5 has three different types of ground, each with a different function. The three types are: 1) Protective earth or chassis ground (PE)
Page 129 If an analog signal does not exist on the previously motioned terminals when the mode is selected (0 mA when 4-20mA is selected, for example) the LMV5 will fault. See section 3-3 for wiring. If the incorrect mode of load controller is selected for the connected instrumentation or analog signal, the LMV5 will fault.
Page 130 If a cycling switch is placed in this loop, and cycles off, the LMV5 will lockout. 3) If an external load controller (such as a RWF40) is used, or the LMV5 load controller is in any external load controller modes (ExtLC modes 1, 5, 6), then a cycling switch should be put in series with the burner on /off switch wired to X5-03.1.
Page 131 Thus, power will be removed from the high and low gas pressure switch commons when the gas valves open. 4) If terminal X4-01.4 (alarm) is energized when a fault does not exist on the LMV5, this will cause a manual lockout of the LMV5.
Page 132 The QGO20 sensor can take up to two hours to achieve operating temperature on the first start-up. Anytime the LMV5 system / PLL52 has power and parameter O2 sensor is set to activated, the PLL52 will try to maintain the QGO20 at approximately 1292...
Page 133 However, if one input or both inputs are configured for a sensor, (set to Ni1000 or PT1000) and that sensor is not wired in or is not reading, the O2 trim will not activate. LMV5 QSG Rev 4 Sec 5 Pg 7 www.scccombustion.com...
Page 134 “O2 Module not active or not Available”. Check the CANBus wiring to the PLL52 Module. If this wiring is not correct the LMV5 will not auto detect the PLL52 Module. Point must lie 0.5 % O2 above O2 Monitor Curve When setting the O2 Control Curve, messages are received that say “Point must lie 0.5 % O2...
Page 135 When the points on the O2 control curve are set, the LMV5 will prompt at every point with press enter after the O2 value has stabilized. Pressing enter then sets the %O2 for the O2 ratio control curve.
Page 136 Also ensure that the safety loop (X3-04 Pin 1 and Pin 2), and the burner flange (X3-03 Pin 1 and 2) are closed. The LMV5 will not standardize if an alarm is present. Note: When standarization is activated in the LMV52, the air actuator should drive to prepurge position before the run / stop contact closes and the LMV52 puts out 19.5mA.

Page 213 4) The ability to view and save trends (particularly useful for tuning PID loops) 5) A “dashboard” to view all of the LMV5 inputs and outputs as well as the operating state. The pages following the installation and set-up procedure will explain how to execute these additional functions that the ACS450 offers.
Page 214 9) After the connection at the user level is successful, disconnect from the AZL5 and then reconnect at the service or OEM level, if desired. Remember that a password will be necessary to access the LMV5 on a service or OEM level, and that the password is case sensitive.

Page 216 LMV5, ACS450 will not permit the .par file to be uploaded to the LMV5. The exception to this is if the burner ID on the LMV5 is blank. If the burner ID is blank, then the upload is permitted. If the burner ID is different, two options are available. The next two steps (11 and 12) detail these options.
Page 217 11) Change the burner ID on the LMV5 to match the burner ID contained in the .par file. This can be done via the ACS450 or though the AZL5 directly. The OEM password is required to do this with either method.
Page 218 3) Locate the correct .bin file. The ACS450 will prompt for the file later in this procedure. The .bin file that is necessary for the update is shown below. Contact Siemens to obtain the .bin file if the correct file is not available on the PC.
Page 219 Type a appropriate name in front of the .tbd extension. Thus a valid name would look like : siemens.tdb Notice that the * is no longer in the name. 2) After the name is typed in, click on Open. Also click on Yes when the window appears asking if you would like to create the file.
Page 220 When connected to the AZL5, the ACS450 can provide an overview screen or “Dashboard”. This provides an useful summary of the LMV5 inputs and outputs, as well as the operating state of the LMV5. The following steps outline the procedure for viewing the ACS450 “Dashboard”.
