General Information Purpose

Intended purpose The FMS 4 / FMS 5 Combustion Management System is a control unit for FMS 4 / FMS 5 combustion systems.

Brief description

The FMS 4 adjusts up to four control elements as a function of a control variable (generally the burner load) according to freely programmable curves.

The FMS 5 adjusts up to 5 control elements as a function of a control variable according to freely programmable curves).

2 sets of curves (e.g. for oil or gas) can be filed as standard, with the option for 4 or 8 sets of curves.

Examples of possible control elements:

- Combustion air damper - Re-circulation fan

- Combustion air fan - Flue gas damper

- Fuel quantity - Flue gas fan

- Atomiser steam

Up to 20 points can be programmed for each channel. The display is relative between 0 and 999.

The FMS has two correction inputs for shifting the setting curves, allowing a feedback control (e.g. O control unit) to be connected up.

Each output is freely configurable, either three-point step control element output for direct actuation of a motor or constant output (on the FMS 5

the 5 channel is always constant). The constant output can be set to any of the following variables:

- Current signal 0 … 20 mA

- Current signal 4 … 20 mA

- Voltage signal 0 … 10 V

The FMS 4 also has a so-called monitor output. In addition an internal value (such as the load position of the burner or position of the gas control element) can be outputted by means of 4 … 20 mA signal).

The FMS has one serial interface for remote control/ display via PC (Windows software available separately) and for connection to other system components via BUS (e.g. fault message system, O control).

Connections for Interbus-S, Profibus, Modbus and CANBUS are available as options. Other BUS systems on request.

The FMS constantly monitors its own functioning and that of the control elements connected.

Each analog input (control variable and feedback or correction) is freely configurable via plug-in cards.

Alternatively:

- Potentiometer (1 5kS) - Step input (DPS)

- Current signal 0/4 … 20 mA - Namur transmitter as a two-wire system

- PT 100 - inductive sensor with switch terminals in three-wire system

The unit is of error-proof construction.

General Information Purpose

Application - internal output regulator (optional)

Application - internal O regulator

(optional)

The FMS contains a burner control unit with process control program.

Outputs:

- actuation of gas valves

- actuation of oil valves

- actuation of the ignition valve and ignition transformer

- fan release

- oil pre-heating

- fault signal

- signal outputs for oil and gas operation

(in the off condition, oil operation is always indicated)

The external signals to the control unit are via floating contacts or chains of contacts.

The following signals can be pre-set:

- 3 separate safety interlock circuits

- fault unlocking

- air pressure monitor

- gas pressure monitor (min.)

- flame signa

This software option makes it possible to calculate the burner's required load setting continuously for a specified target value (referred e.g. to temperature or pressure), through comparison with the actual value. This load setting can be notified internally to the electronic compound as the specified value.

This software function makes it possible to regulate one or several actuators independently of a switched-on O actual value. By using a self-optimising

regulator strategy, it is also possible to regulate burners with frequent load changes.

l (pilot flame monitor and ignition flame monitor)

- pre-ventilation and ignition release

- pre-ventilation suppression

- control release

- re-circulation release

- burner on

- fuel selection

General Information Using these instructions

Purpose of these instructions These instructions are concerned exclusively with commissioning and

servicing.

Further information, for example design examples, possible uses, software settings etc., is given in separate booklets.

Special information dealing with optional equipment on this unit is explained in separate booklets.

Preliminary clarification To make the best use of these instructions, proceed as follows:

Check whether the settings of your FMS meet the system requirements. You will find the settings on the sticker on the unit.

- Which physical quantities (current, resistance) and values does your FMS need on its inputs?

- Which physical quantities (current, voltage, relay signal) and values does the system expect on the outputs of the FMS ?

- Do the settings of the FMS match your requirements with regard to operating behaviour (pre-ventilation, feedback etc) ?

Should these matters not be clear, please read the section "Settings” (page 16-29)

Finding the appropriate section Determine what operation you wish to perform on the FMS.

When initially putting into operating or tracing the cause of a fault, a function test is first recommended. You must then decide whether you wish to program with the burner stationary or running and whether or not an entire curve is to be programmed.

Identify your current requirement from the table of contents and turn to the appropriate page.

Conventions Sub-headings

Serve as a guide if you can already handle the FMS and merely want to refer to certain information again.

Lines in italics after the sub-headings

describe what the current state of the system should be. If this is not the case, the subsequent operations will not show the desired result.

Lines in bold type indicate an action which you are to perform.

General Information Using these instructions

The figures and letters in brackets (1), (2), (3), (4), (5), (6), (7), (8), (A) and (B) relate directly to the picture of the front panel. They identify the part on which the specified action is to be performed or on which a reaction can be seen.

The lines in ordinary typeface below the procedural instruction describe the reaction of the system or unit following the operation.

The figures at the right-hand margin denote a paragraph in the "Fault Correction” section of these instructions. If the reaction indicated does not occur, please refer to this. It describes the possible causes of faults and how to rectify them.

___________________________________________________________________

The word in italics between two lines and the sign

are notes for a better understanding of the operation or notes on how to avoid incorrect operation.

___________________________________________________________________ ___________________________________________________________________

The lines in bold italics between two lines and the triangle

draw attention to dangers. The instructions given there must be followed. ___________________________________________________________________

If you now follow the operations step by step, paying attention to the instructions, you will automatically be working correctly. If any of the reactions indicated do not occur, there is a fault with the unit or the system. You should correct the fault first before proceeding.

Fault correction Follow the instructions identified by the figures given after the fault codes

and after the procedural instructions. You may find the solution to your problem there.

This section, however, makes no claim to completeness. Should the actions described there not have the desired effect, the unit or parts of the unit (e.g. front panel etc.) must be changed. If the fault still occurs you are dealing with a fault specific to the system.

General Information FMS Operating Principle

FMS Digital Inputs For the FMS to function according to the requirements of a combustion

system, the condition signals from the system must be relayed to the FMS.

These signals include:

Pre-ventilation suppression Air pressure monitor Gas safety interlock circuit Gas pressure > min. Oil safety interlock circuit Ignition flame Boiler safety interlock circuit Burner on Ignition position acknowledgement Fault reset High firing rate acknowledgement Re-circulation On Fuel selection Control release Flame signal Set-point switch over

(only with integral load control unit)

For use in burner control, the FMS emits 9 digital signals, which are converted by relay module (type 6 60 R 0016) into twelve output signals for 230 V:

Main gas 1 Ignition valve Main gas 2 Ignition transformer Oil Release ignition gas line Heated oil distribution Fan Oil operation signal Pre-ventilation / post-ventilation Gas operation signal Fault signal

___________________________________________________________________

FMS operating sequence The operating sequence described relates to a usual configuration of the (for diagram of example, unit. The various parameter settings can result in a somewhat different see appendix) sequence.

___________________________________________________________________

A signal is first sent to terminal 2 (burner ON), indicating when the burner is to start. The FMS then interrogates the safety interlock chain for the selected fuel and the air pressure monitor contact. If the fuel is selected via the fuel safety interlock circuits, the FMS performs a plausibility check. If it does not detect a satisfactory condition, a corresponding text message is emitted and the process control stops. If all signals are OK, the fan output is activated and the ducts run to their bottom stop as a check. The "pre-ventilation/post-ventilation” output is activated. Once all ducts have reached their bottom stop, they open for aeration. Any leakage test configured runs in parallel.

In the case of control elements, aeration is used to enter and to check the range limits. The fuel control element, after reaching its top position, runs back into the ignition position. All other ducts remain in the open position. The FMS now interrogates the high firing rate acknowledgement and the air pressure monitor. If these signals are OK, the parameterised aeration time runs. If a duct is configured for re-circulation, this opens with a time delay. On reaching the parameterised re-circulation delay time, the pre-ventilation time stops. As soon as the re-circulation duct has reached the aeration position, the aeration time continues. Once this time has elapsed the ducts run into the programmed ignition position (re-circulation fully closed). Once all ducts have reached ignition position, the FMS interrogates the ignition position acknowledgement. In gas operation the gas pressure monitors must also be in a satisfactory condition prior to ignition. The ignition transformer is now activated alone for the duration of the pre-ignition time (transformer start-up time).

General Information FMS Operating Principle

Start without pilot burner: The main valves open and remain activated together with the ignition transformer for the duration of the safety period. During this time the flame signal appears.

Start with pilot burner: The ignition valve and main gas 1 are opened. The pilot flame forms and

the flame signal appears. Once the 1 safety period has elapsed, the pilot burner burns on its own. The main gas 2 then opens and remains activated

in parallel with the ignition valve for the duration of the 2 safety period. When this period has elapsed the ignition valve closes again.

When ignition is completed the re-circulation duct and the flue gas damper run to the programmed point. Correction is activated. All ducts may run to the programmed base load point (depending on the setting selected). The FMS remains in the base load position until control release (terminal 4) is given.

Following control release the FMS follows the prevailing external load. A current signal proportional to the position of the compound is emitted as internal load (not on FMS 5). Withdrawal of the signal/control release during operation allows the compound to run at base or ignition load (configurable).

Withdrawal of the terminal 2 signal is followed by shutting off. The main valves close. (In gas operation, main gas 1 first, followed by main gas 2 with an approx. 5-second delay, in order to allow the monitoring line between the solenoid valves to burn out. In the event of a fault shut-off, however, they both close immediately). If configured for post-ventilation, the air ducts open again for this period. After the configured after-burning time the FMS again checks for a period of 5 seconds whether the flame has gone out. If not, a fault shut-off occurs. The FMS then goes into "OFF” mode.

Pre-ventilation suppression The pre-ventilation range can be skipped by means of the pre-ventilation through an external signal suppression signal (terminal 1). If the signal is present straight away at

burner start-up (terminal 2 signal), the control elements run directly to the ignition position. In order to enter the range limits, however, pre-ventilation should be performed once after "Clear Memory”. Pre-ventilation suppression can only occur, however, if this function is activated via parameters.

Automatic pre-ventilation When activated by parameters, the FMS starts after regulator switch-off suppression automatically without pre-ventilation. Pre-ventilation is only carried out now after

fault switch-off or power failure. Using this function is subject to the regulations applicable to the facility.

Range limits

A so-called servicing mode can be set via parameters. The control unit then runs until the stabilisation period. In this mode 5 successive starts are possible without the need for pre-ventilation and without a leakage test.

The 5 start is automatically followed by pre-ventilation and/or a leakage test.

It can be determined by way of parameters how long the FMS may take after a start signal (terminal 2) until ignition occurs. If this length of time is exceeded, a fault shut-off occurs. If the content of the parameter is set to 0, no fault occurs (= program monitoring time = T).

Automatic restart can be activated via parameters. The control unit attempts a one-off restart in the event of any fault marked with * after a factory-set period (standard: 10 sec). This restart can be prevented by setting the period to 0.

n the case of firing systems according to EN 676 the parameter must

be set to "0”.

The standard setting is without restart.

The control unit may optionally also perform the leakage test on the gas valves. The leakage test can per performed before ignition and/or after shut-off

The leakage test is performed by way of the main valves. The use of filling and discharge valves is also possible by means of relay switching.

The FMS offers the facility for using two curve sets for each fuel (e.g. summer/winter operation) or a mode with and without speed.

When using Option 4: Curve sets, it is possible to switch within one fuel selection from one curve-set to the other (flying curve change). Fuel change can only be performed via "Off”.

When switching the fuel selection switch over (terminal 75), the FMS first moves automatically to the base load position. Then the system switches off. Only then are the fuel selection and thus the curve set changed over. If the "Burner on” signal is still present, the burner starts with the new fuel. (This function is not available with Option 4: Curve sets).

In the 1 pre-ventilation after "Clear memory”, the FMS determines the maximum range of travel for each control element and stores this automatically. If no ranges limits have yet been determined, the setting (in the case of constant outputs the feedback setting) in pre-ventilation stands at 0 and 999 points respectively. At all further starts a check is made to see that these range limits are correct. Should the limit switches be shifted or the frequency converter setting changed after programming, the range limits must be re-entered.

If the range limits cannot be determined automatically, they can also be entered manually by way of parameters. If the FMS has no existing range limits, it automatically takes the top and bottom point of the curve as the limit. It then does not go beyond this.

General Information FMS Operating Principle

The internal load is the load value at which the compound currently stands. It therefore corresponds indirectly to the output of the burner. The internal load is displayed in addition to the external load signal. In the "load value” position therefore both the external load (left-hand) and the internal load (right-hand) are displayed.

The value of the internal load can be outputted via the monitor output, in order to connect further units (e.g. O control, only on FMS 4). When

connecting other units, it must be remembered that the signal in itself is not error-proof.

When switching over to "Load value” with the burner running the burner load can be set via the FMS. The load value can then be adjusted with the channel 1 toggle switch. The system follows this load value in the compound. Operating a switch other than channel 1 causes the unit to exit manual mode again.

The person commissioning the unit can adjust various functions of the

FMS

by way of parameters (e.g. post-ventilation time). The parameters are classified into various safety levels. With the exception of the lowest safety level these are accessible only with a password. The parameterisation can be undertaken both on the unit itself and by means of a PC and Windows software.

The FMS has 2 correction inputs. An analog signal (0/4 … 20 mA) can be connected to these for shifting the set curves (e.g. for O correction or air

temperature correction). The assignment of the correction to the individual output channels and the mode of operation can be adjusted via parameters.

If the FMS cannot perform a correction because a control element stop has been reached, it adjusts the internal load and hence the compound until the correction can take effect as required.

An output for controlling the speed of a combustion air fan or a re-circulation fan etc. can be monitored by switching the pulse output of a Namur transmitter directly to the FMS.

Continuous outputs and three-point step outputs have different feedback requirements. In the case of continuous outputs comparisons are made between output and feedback values in or to check the plausibility. The units therefore do not have to be intrinsically error-free in order to form the feedback signal. For availability reasons (minimisation of interference) the reproducibility of the values should be as good as possible.

For technical reasons this method cannot be used in the case of three-point step outputs. For this reason TÜV approved potentiometers must be connected directly as feedback to the FMS. These potentiometers must positively render the position of the damper.

Normally during pre-ventilation each control element runs as far as ist uppermost stop. Now, by means of parameters, a limit can be set for each channel that is not exceeded during pre-ventilation.

General Information FMS Operating Principle

Energy-saving mode for The brightness of the display can be adjusted to the ambient light running text display conditions by means of parameters.

In addition the display can be set to automatically revert to the lowest brightness level if not operated within a given period of time.

Separate ignition point In the standard version the ignition point is situated outside the accessible

range in order to set a separate fuel/air ratio. By means of parameters, however, the ignition point can be adjusted so that it lies on the compound curve.

Integrated power control unit An integrated power control unit is also available as an option. Where this (option) is used the actual temperature or the actual pressure is directly switched

instead of the load signal. The control parameters are adjusted via parameters. It is also possible to change the setting (daytime/night time

The integral output regulator is a PID controller with special combustion technology functions. It can be used as a fixed-value regulator or as a weather-dependent regulator. The following signals can be set:

- Actual value (analogue)

- External temperature or some other analogue signal for target value shifting

(only in weather-dependent regulators)

- Target value switching (via zero-potential contact)

Combustion enabling by the output regulator takes place internally in the FMS Boundary values that switch the burner on and off, need to be set via parameter

regulation - optimises combustion systems

- saves fuel

- minimises pollutants

The main purpose of O regulation is to compensate for perturbations that

affect combustion. In addition, the O regulation system monitors the

combustion's fuel/air ratio. A message is output at once if it strays outside the permitted limits. The following are the main perturbing factors that affect combustion:

Air: Temperature Contamination: Burner

Pressure Boiler Humidity

Fuel: Calorific value Mechanical systems:

Temperature Mechanical Viscosity hysteresis Density (free play) Gas pressure fluctuations

The O control unit is implemented as a free-standing software module.

The unit compares the residual oxygen content in the exhaust gas of a

combustion system measured by means of the LT1/LT2 Lambda transmitter (actual value) with the optimum residual oxygen content (target value). The target values are stored in the instrument in the form of an installation-specific curve. The control unit applies a correction until the actual value corresponds to the target. The calculated output value of the O control module is transmitted to the compound module as a correction

Significance of ID number The ID number comprises 8 characters, e.g. 664 V 0010

The two figures before the letter denote the unit, in this case a FMS 4. The letter denotes whether the unit is a VMS or a FMS. The penultimate figure provides information on the unit hardware. It also determines which connection diagram applies (see appendix).

Inputs The inputs can be configured on the backplane by means of plug-in

configuration cards. Any of the following can be connected up to each input:

- a potentiometer in the range from 1-5 kS

- a current signal 0 … 20 mA or 4 … 20 mA

- a step signal ("OPEN CLOSE" commands)

- a frequency signal (Namur transmitter), for details see appendix

- a PT 100 element

- flame sensor module (in preparation)

- a potentiometer module (in preparation) There is a plug-in card for each configuration. This is inserted into the

respective socket in order to configure the input.

Configuration sticker The factory setting is entered on a sticker on the side of the unit.

This corresponds either to the customer data or, if nothing was specified, the standard setting (see condition on delivery).

The EEPROM checksums and thereby the software version are also entered on this sticker, together with the configuration number and hence the hardware setting.

Configuration number The configuration number is a 15-digit number, constructed according

to a fixed code.

Settings Parameters

Parameter setting The parameter level can be accessed by turning to the "Parameter”

selector switch position. When working on level 1-4, this works only with the burner stationary (i.e. no signal on the digital inputs). Only level 0 is accessible with the burner running.

___________________________________________________________________

As a rule, the factory parameter settings are precisely tuned for the installation for which the unit has been designed. Therefore, it is only necessary to change parameter settings in exceptional cases.

___________________________________________________________________

Access levels The parameters are divided into four different access levels according to

function and safety classification:

Operating level (Level 0)

! Accessible without password, non-critical parameters that may possibly

have to be altered during operation.

Customer level (Level 1)

! Accessible with modifiable password (on delivery set at "0000”), access

to parameters, adjustment of which calls for technical knowledge, which are tailored to the system and which are not altered during operation.

Service level (Level 2)

! Accessible with a fixed password, but only to personnel specially trained

in parameterisation. Access to all parameters that are not fixed on the basis of standards and technical regulations.

Production levels (Levels 3 and 4)

! Access to all parameters (only possible through LAMTEC)

Each parameter level is protected by its own checksum. This checksum serves to show that no changes have been made (see page 78).

Leakage Test Mode of Operation

Integrated Leakage Test (option)

Leakage test flow chart

Integrated leakage test The leakage test checks whether the main gas valves are leak-tight. (option) The supply gas pressure is used for this purpose. Since the leakage test line

(space between the two main valves) burns empty in the event of a shut-off, this part is normally pressureless when starting (gas pressure > min. = 0). The FMS checks this. Main gas 1 is then briefly opened and gas flows into the test line (gas pressure > min. changes from 0 to 1). This pressure must then subsist for 30 seconds. The leakage test is then deemed to be completed. If the leakage test line is not empty at the start (e.g. as a result of a fault shutoff previously), main gas valve 2 is opened first. The leakage test line is thus vented (into the combustion chamber or over the roof, depending on the system, for suggested circuit see next page). A check is then conducted to see whether the line remains pressureless for 30 seconds. Otherwise the procedure is as described previously.

The leakage test can be performed before ignition and/or after shut-off. Selection via parameters.

The pressure monitor for the leakage test line must be connected to "Gas pressure >min” input (terminal 73). It also monitors the minimum pressure during operation. If another minimum pressure is to be monitored during operation, however, the pressure monitor is, for this purpose, to be looped into the gas safety interlock circuit.

The test line, however, must be designed so as to ensure that the test time of 30 sec. per valve is sufficient to reliably detect a leak of 0.1% of the fuel gas

consumption at maximum firing heat output, but at least 50 dm /h.

Calculation formula An (approximate) formula for calculating the leak test facility is compiled

below: Definitions: GDW gas pressure monitor

V1 gas-side safety shut-off device V2 burner-side safety shut-off device

barometric air pressure 1000 mbar lower switch point (falling) of GDW upper switching point (rising) of GDW switch difference of GDW gas flow pressure (supply pressure before V1) volume of gas line tested leakage quantity maximum admissible leakage quantity (limit) testing time (30 seconds, fixed)

That is, for a maximum gas flow rate of 50 m /h the formula is:

inserting the numerical value for in mbar. For a gas rate of flow Q of >50 m3/h the formula is:

inserting the numerical value for Q in m /h and for in mbar.

Examples: A. Assuming: = 20 mbar, gas rate of flow < 50 m /h: i.e. the gas line to be

tested must be no

greater than 20.8 dm

in order to be able to detect the leakage quantity demanded

B. Assuming: = 20 mbar, gas rate of flow = 200 m /h:

i.e. the gas line to be tested must be no

greater than 83.3 dm

in order to be able to detect the leakage quantity demanded of 200 dm /h.

Suggested circuit for venting the gas line over-roof in conjunction with the combustion management system

* If after shut-off the test line is not vented over-roof but is to be burned off into the combustion chamber, a timer relay with a delayed cut-out of 2 … 5 sec is to be used.

Output regulator (optional) Method of operation

Procedure description The burner's startup proceeds exactly as already described, except that an

enabling command to start the burner must have been provided by the output regulator. In other words, the actual value must be smaller than the set-point by an appropriate amount. The output regulator only operates once the burner has fired up and the signal "Enable regulation” (terminal 4) has been given. Load specification for the compound is then provided via the integral output regulator. It depends on the difference between the actual value and the set-point, and on the control parameters set. If the actual value exceeds the maximum value set, the output regulator shuts down the burner.

The load regulator is only active in "Automatic” mode.

Weather control If the output regulator is configured as "weather controlled”, the set-point

can be shifted between the parameters SetpointMin and SetpointMax by altering the value at the redundant feedback channel 1. When the regulator is weather-controlled, the outside temperature is taken into account when calculating the set-point. The operator can input a minimum and a maximum set-point, between which the outside temperature can determine the set-point (see diagram).

With the weather-controlled option activated, an external set-point specification can also be implemented.

Set-point switch-over The set-point can be switched over via a digital input. In versions with a

fixed set-point, this contact can be used to select between the two values entered in the parameters list.

If, in addition, weather control is activated, a selection is made between two pairs of limiting values (see Weather control and Limiting ranges). The parameters for Set-point 1 (for set-point switch-over) and Set-point min. 1 (for weather control) are equal. Similarly for the parameters Set-point 2 and Set-point min. 2. The relevant content is assigned in accordance with the configuration.

Activating the "Weather control” option and adjusting the variable parameters can also be used to implement external set-point specification. In other words, the set-point can be altered manually or automatically via a potentiometer (or switched through resistors). Thus, by connecting a double-throw switch, night-time reduction could be implemented instead of weather control. Night-time reduction and weather control can be achieved simultaneously by combining the weather controller with the setpoint switch-over. When the weather controller is active, the compound's feedback can no longer proceed completely redundantly.

Startup circuit The load regulator has a startup circuit, in order to brake the burner's start

load. The startup circuit is run during each new burner start. The internal load is held at a value adjustable by the user, for as long as the boiler is cold (actual value is below a user-adjustable limit). If the regulator's actual value is equal to or larger than the parameterised startup maximum temperature, this limit is overridden.

In order to prevent a situation where with an excessively large demand on system output, the boiler temperature necessary to override the startup circuit is not reached, a startup timer is also triggered in parallel (this timer can also be adjusted by the operator). Once the internal load's value reaches the parameterised startup load, the output limit is increased linearly step-wise up to the maximum load. The slope of this linear increase is calculated from the parameterised startup time.

Countdown until the internal load reaches the specified load

Normal operation

Ignition procedure

Basic load Ignition

Output regulator (optional) Method of operation

Thermostat and control region The thermostat function switches the burner on or off, as a function of the

temperature and/or pressure. However, this only happens if the burner has been enabled by the startup signal. The control region is formed by entering the regulator's set-point and the "Burner on” value (parameter). The shutdown hysteresis is divided into 3 regions. Generally speaking, the first section lies below the set-point. The second section lies above the setpoint and bounds the control region, whilst the third section also lies above the set-point and forms the rundown region. Thus, the control region can lie asymmetrically around the set-point.

Within the upper and the lower control region, the load regulator operates in accordance with its set parameters and specifications. If the regulator's actual value reaches the rundown region, a basic load demand is output to the compound. If the regulator's set-point exceeds the rundown region, the regulator is shut down. This takes place either through internal processing (if the controller is integral, i.e. FMS), or via a relay if the controller is an external device (VMS). A new startup can take place once the actual value falls below the switch-on point. This function can replace the control thermostat required in the system.

Manual control The output regulator's load specification can be overwritten by setting the

selector switch (2) to "Load” and pressing the Channel 1 switch (4) upwards. This manual load control is cancelled by pressing the Channel 2 switch downwards. The shutdown limit is non-operational in manual mode. Hence the manual mode can be used to test the safety limiter.

___________________________________________________________________ In manual mode, the load regulator's functions such as startup circuit

and control thermostat are switched off therefore always monitor the system continuously when using manual control.

Setting the output regulator The output regulator is only adjusted via the parameters.

Control region The regulator's set-point lies below the value "Upper control region”

"Burner on” value (parameter 802). The content of the parameter "Switch-on point” is subtracted from the setpoint, giving the switch-on value. The value of the "Upper control region” (parameter 803) is added to the set-point and forms the control region's upper limit. Thus, the control region can lie asymmetrically around the setpoint. The switch-on point can also be above the set-point; a negative value (<0) needs then to be input.

The rundown region is limited from above by the parameter "Burner off” (parameter 804). The parameter is added to the set-point. If this value is exceeded, the burner is shut down (either internally via the controller in FMS mode, or via a relay output in VMS mode).

The region between the "Upper control region” and the "Shutdown limit” is the rundown region. If the actual value reaches this region, the compound returns to base load.

It also follows from the above that in general, the value in "Burner off” is greater than the one in "Upper control region”. Otherwise there is no rundown region, and the burner is shut down directly when reaching the limit.

Regulator behaviour The load regulator attempts to adjust the actual value to the set-point.

A direct relationship between the internal load and the boiler's temperature is assumed. In other words, the higher the internal load, the faster the boiler's temperature rises. The load regulator would not function if the curves were programmed otherwise. Four parameters determine the regulator's behaviour:

Readjustment interval

The readjustment interval determines how often the deviation is monitored and a new adjustment calculated. Example: a value of 10 in parameter 808 means that this procedure is carried out every ten seconds. The value should correspond to the control section's lag time.

P-factor

The proportional factor acts directly on the deviation, i.e. the difference between the set-point and the actual value. The set factor is divided by 10 for the adjustment. Example: with a set-point of 500, an actual value of 460 and a P-factor of 12, this results in a proportionality fraction of +48.

( 500 - 460 ) C12

_______________

I-factor

The integral factor is calculated from the momentary deviation and the previous deviation from the set-point. The set factor is divided by 10 for the adjustment. Example: with a set-point of 600 and a momentary actual value of 620, this results in an actual deviation of -20. Assume the actual value was 622 at the last calculation, i.e. before the set readjustment interval, giving a previous deviation of -22. With the factor set to 5, the adjustment would be

-21 points (-42 x 0.5).

D-factor

The difference factor is calculated from the change in the actual value. It is also divided by 10. Example: the previous actual value (before the readjustment interval) was

600. The current actual value is 605. With a D-factor of 50, this results in a D-fraction of -25 points (-5 x 5).

Readjustment interval 10 s

Regulator behaviour All three fractions (P-fraction, I-fraction, D-fraction) are added together and

act as an adjustment to the compound regulator's load specification. The value is added to the momentary internal load. As long as the actual value is below the set-point, the P-fraction and the I-fraction are positive, i.e. both these fractions act to increase the load specification. Only the D-fraction is still negative in such a case (assuming the boiler's temperature is rising). A sufficiently large D-factor should be selected, in order to avoid an excessively large overshoot during burner startup. The D-fraction can also be increased by increasing the readjustment interval, since the boiler has more time for a change in temperature. If, despite a large set-point deviation, the burner is not driven to full load or base load respectively, the P-factor should be increased. The larger the readjustment interval, the quieter the compound but also the larger the actual value's deviation from the set-point and the slower the adjustment. The overshoot effect can result in a failure of the control mechanism, hence the readjustment interval should be so selected that the compound (the internal load) settles down.

Before commissioning

Adjusting motor As soon as the FMS is supplied with voltage, it attempts to drive the actuator limit switch motors to the lower boundary of the factory curve. If the end-bearing's

limit switches are not properly adjusted for this then the motor may hit the actuator's mechanical stop. ____________________________________________________________________

This can damage the motor or the valve. ____________________________________________________________________

Therefore: Check the position of the end-bearing limit switches in the motors, taking into account the motor output shaft's travel.

If in doubt, set a shorter travel. It can be readjusted later.

FMS Commissioning O regulation

Automatic functions control

during operation

Checks during burner start-up This tests whether during pre-ventilation, the O actual value has complied

with the air value (no smaller than 18 vol.% O and smaller than 24 vol.% O ).

After ignition, the O actual value should have reached a value of no less than

14% within 45 seconds. Reaching the threshold value is monitored. If one of the two values is not met, O regulation is deactivated. The regulator outputs

"Base value without regulation”.

O monitoring bands The O actual value is constantly checked during burner operation for one

maximum and two minimum permitted values. These ranges are located around the O target value as a function of the load.

If the actual values are outside these bands over a defined period of time, regulation is deactivated and the warning "Fault” is output. Thereafter, the regulator output (correction input) corresponds to "Base value without regulation” or "Base value for air shortage” as relevant.

Automatic functions control

during operation

The monitoring bands can be parameterised for 2 fuels, oil/gas, referenced to each fuel (parameters 923 to 934). In the case of more than 2 curve sets, these can be assigned to the individual curves via the parameters 912 and

913. The permitted deviation is calculated as a percentage of the target value. Two separate percentages can be specified for basic load and full load. The range between those is interpolated linearly.

Monitoring/shut-down times: 1st monitoring band 120 seconds; active

after "Regulator on” 2nd monitoring band 30 seconds; active

after "Burner on”

Factory settings: 1st monitoring band in the upper direction

Basic load (parameters 923/925) 60% Full load (parameters 924/926) 100%

1st monitoring band in the lower direction Basic load (parameters 927/929) 40% Full load (parameters 928/930) 50%

2nd monitoring band in the lower direction Basic load (parameters 931/933) 50% Full load (parameters 932/934) 70%

Dynamic probe test During active operation, the measured O value is monitored by the main

processor for any changes. If no greater fluctuation than 0.2 vol.% O is

detected over a period of 10 minutes, the fuel/air mixture is altered to force an air excess. If after 1 minute there is still no change in the actual O value,

the test is repeated with a higher air excess. If this does not cause a change in the actual value, this test is repeated yet again with an even higher air excess. If even this does not force a change in the actual O value, the regulator

deactivates itself and displays a warning notice. Thereafter the regulator output (correction input) corresponds to "Base value without regulation”.

Probe blockage Blockages in the probe can cause the measured value to increase slowly but

steadily, in such a way that the dynamic probe test is not triggered. The main processor monitors whether the actual O value drops by more than

0.2 vol.% O at least once within 15 minutes. If this is not the case, then a

dynamic test is triggered.

Note: O optimisation fault messages have no effect on the burner's function or that

of the combustion system. They only notify that:

O optimisation was deactivated.

Note error status and load value. If desired, it is also possible to have the burner shut down on "Air shortage” faults via parameter 897.

Correction output monitoring If the O correction output is constantly greater than 98% [980 points] over

60 minutes, the O regulator is deactivated for safety reasons. The base

value for "Deactivated regulation” is output. If thereupon the O value

increases significantly, then the O regulator is reactivated as soon as the O

value is (e.g.) at another load setting in the 1st monitoring band.

FMS Commissioning O regulation

Regulation strategy

The regulation strategies employed were specially developed and optimised for the circumstances prevailing in combustion facilities:

- Frequent output changes,

- long lag times.

During burner start-up, the O regulator remains on standby until it is

ensured that plausible O measured values are being displayed.

Factory setting 90 seconds after ignition this is adjustable via parameter 904.

The "Neutral value” is output during standby. It is calculated automatically from the range set. Ignition takes place with the neutral value. The neutral value depends on the selected correction mode; e.g. at -50% to +50%, the output correction value (neutral value) is 500, whilst at -30% to +70% it is 300.

Note: The neutral value corresponds to the basic setting of the

VMS/FMS without regulation.

In the case of fuel/curve switching during operation, the neutral value is output during the switch-over. An air advance can be set to the neutral value by means of parameters 702 to 704. O regulation is reactivated, with a time delay, once the switch-over is

completed. Factory setting 30 seconds, adjustable via parameter 903.

Various regulation strategies are available.

In the event of a fault, "O regulation base value deactivated” or "Base value

for air shortage” is output, depending on the cause.

Regulation strategy

With pre-setting for load O regulation by means of a comparison between target and actual values is

changes (standard regulator) only performed if no output change (load change) takes place ("internal

load” static). After a preceding load change, an target/actual value comparison is performed and an actuation step triggered only after expiry of the set lag time (parameters 898 and 900).

If the O actual value corresponds to its target value, the current correction

value, referenced to the load vale and the load direction, is stored in a table. The updated value is output at the next load change.

A pre-update is already carried out as from the 2nd target/actual value comparison, after a load change. As soon as the actual value gets close to the target value, the correction value is updated.

When the load changes, regulation is terminated immediately after target/actual value comparison and the neutral value, or if relevant the correction value obtained (updated) for this load point, is output D pre-setting!

Regulation after a target/actual value comparison is only performed again if the load is stationary and on expiry of the lag time.

In this type of regulation, the overshoot is automatically deactivated in the VMS/FMS. The actuators' hysteresis is compensated for by the load direction-dependent updating of the correction value.

Regulation strategy with pre-setting for load changes

1 Pre-ventilation/ignition

The correction is switched off; i.e. the neutral correction value is output.

2 O regulation on standby

The "Correction value with deactivated regulator” specified in parameter 901/902 is output.

3 Regulator takes over the neutral correction value,

or the updated correction value is output.

4 On expiry of the set lag time, the residual deviation between target

and actual value is corrected.

5 Load change

O regulation is suspended and pre-setting carried out - neutral

correction value, or the updated correction value is output.

6 Regulation is deactivated, e.g. by a fault

The correction value for deactivated regulator specified in parameter 901/902, or the one specified in parameter 917/918 for "Air shortage”, is output.

Regulation strategy

Parameter 896 can be used to select whether the pre-setting is always (at each load change) to be activated (factory setting Standard 1), or not activated (content 2).

Furthermore, the updating too can be turned off. It is then possible to select whether, at load changes, the neutral correction value or the "Base value without regulator” is to be output (parameter 896). The overshoot becomes active again when updating is turned off.

Extended regulation Regardless of the selected regulation strategy and the lag time set strategy (air shortage) (parameter 898/900), immediate and extensive action is taken by the

regulator to combat any air shortage occurring. The objective is to avoid air shortage and to correct any such shortage as quickly as possible.

Regulator overshooting and the resulting excess air are accepted as unavoidable.

F the electronic compound completely. The integrated O regulator remains deactivated.

Set parameter 896 to 0 "No regulator” or 3 " Only display ”.

Setting the correction The integrated O regulator is connected inline and upstream of the

range and correction mode FMS, as a free-standing program block. It acts exclusively on

correction input 1. The correction signal (actuation signal) transmitted to the FMS is 0...100% with a resolution of 0.1%. 0% corresponds to maximum excess air, 100% to minimum excess air. The factory setting is a correction mode of +60 / -40 when correcting for air-valve / fan and -60 / +40 when correcting for fuel and a neutral value (base setting with the O regulator switched off) of 50%.

This basic setting was selected on the assumption that over time, burner and boiler contamination during their operation would result in the installation's flow resistance increasing and thus a somewhat greater actuation range in the excess air direction could be of benefit.

If some other correction mode is selected by means of parameter 437 (expert level), the base setting also alters at the same time.

With correction mode Base setting

Inputting the Calculation of O target values as part of burner adjustment

O setpoint curve

Note: O -regulated operation is the normal operation. Unregulated

operation should only be considered to be the emergency situation. Hence, the objective of burner adjustment should be to calculate the optimised operation and to store the corresponding curves in the VMS/FMS. The O values calculated as part of burner adjustment are

now input as target values for O regulation.

The excess air required for unregulated operation is set via the base value without regulation (parameters 901/902). This is specified during Regulation off, Regulation in standby etc.

The O values calculated during burner adjustment are input and stored as

follows, regardless of whether the burner is off or in operation. The O target

values can be input arbitrarily. It is not necessary to observe any particular sequence.

Note: The P-factor (proportionality factor, parameter 899) is specified by

means of the parameter setting. The new correction is obtained from the two input quantities, deviation and P-factor. The former is then output to the FMS/VMS. The procedure is repeated after the lag time's expiry. If the internal load has changed during this time, the O regulator exits this

The calculated value should be input by means of parameter 898. Factory setting: 15 seconds.

The lag time can be adjusted to the load via parameter 900. The lag time gets shorter at full load, due to the higher gas velocities. Lag time shortening of 3 seconds is preset at the factory.

To calculate lag time at full load: proceed as described above.

Guideline for 2 or 3-draught boiler: Parameter 898 Z 12 seconds Parameter 900 Z 3 seconds

The P-factor should be so adjusted that a target/actual value deviation of

1...2 vol.% O is corrected within 4...6 steps without overshooting.

Repeat until the target value is corrected within ca. 4...6 steps. Check regulator setting at intermediate and full load.

Note: It is possible to achieve optimisation by means of the P-factor

(parameter 899) and the lag time (parameters 898 and 900), that inter alia also depends on the installation's properties; e.g. one may set a somewhat shorter lag time if the P-factor is reduced at the same time.

The correction is set via the parameter numbers 429-676, of which, however, only a fraction are generally released for use by the person commissioning.

The following settings are possible, expert level only (level 2):

Correction mode and input signal are quoted in the order and are set at the factory. Any change on site is possible only by parameter intervention at expert level.

Available correction modes The correction mode specifies how the correction should act.

Manifold settings are possible. Diagrams 1 and 2 show two typical correction modes for O correction.

Type 1: correction acting Type 1 is used if the correction is applied to a linear actuator,

on the target value e.g. a frequency converter shifting the combustion air blower's

rotation speed. The correction is directly added to, or subtracted from, the target value.

If the correction is applied to a fuel actuator, the effect is reversed so that 0% corresponds to the smallest target value. By using the expansion factor held in parameter 433 - Commissioning level - the correction effect can also be weighted across the burner's output.

curve's slope is taken into account before calculating the correction. Thus, a flat curve results in a small correction range, whilst a steep curve results in a large one.

ATTENTION: This is only meaningful if the curve rises monotonically.

ATTENTION: When applying O corrections, make sure that the combustion limits are

observed even with the maximum correction applied (100%). For details see page 67, "Checking the combustion engineering limits”.

FMS Commissioning Correction

_________________________________________________________

The correction mode indicates how the correction is intended to Aids act. A variety of settings are possible. Figure 1 and 2 show two typical correction modes for O correction.

Type 1 is used where the correction is made on a linear control element, such as a fan frequency converter. The correction is directly added to or subtracted from the set-point value.

Type 2 is used where the correction is made on a non-linear control element such as an air damper. Before determining the correction, account is taken of the steepness of the curve. A flat curve results in a small correction range, whereas a steep curve give a large range. If the correction is made to a fuel control element, the effect of the current is reversed, so that 0 mA corresponds to the smallest set-point.

_________________________________________________________

Do not use if parts of the curve are horizontal. _________________________________________________________

Setting the correction range: The correction range can be set between 0 and 999 via

parameter 517, commissioning level.

Example: A typical correction range for O regulation

is 200. This means: With a correction mode of +40% ... -60% (factory setting) and correction for a target value of +80, the actuation range across which the correction can be applied is

-120 points.

Recommendation: The correction mode and correction range

should be so chosen that the effect on the O value in the direction

of excess air is -2 to 3 vol.% O ,

and the effect in the direction of air shortage is 1 to 1.5 vol.% O

Recall set correction range Selector switch (2) to "Setting”

Selector switch (1) to "Status”

Press Acceptance key (3) Set correction range appears on the display on the respective channel. If two correction inputs act on one channel, the ranges are displayed alternately (e.g. 15 points)

If "OFF” appears on the display, no correction is activated for this channel _________________________________________________________

Take account of correction in subsequent programming The correction must be able to act without the FMS reaching the stop (0 or 999 or limit switch values).

If the correction cannot extend the adjustment travel because a channel does not reach the range limit determined for pre-ventilation, the burner output is increased or reduced until the correction can be extended.

FMS Commissioning Run to shut-off limits

Run to shut-off limits As each monitoring system the FMS has tolerances, which affect the

adjustment precision. With the FMS these tolerances can be affected by parameter settings. If the firing system is adjusted, it has to be ensured that also the flame burns reliably and stably in consideration of these tolerances. In order to prove this it is necessary not only to prove the compound settings to the adjusted setpoint, but to the so-called shut-off limits, i.e. with the actuator values, that the FMS can take due to the permissible tolerances without shutting off just yet. This inspection has to be performed for the whole load range and for every operating mode. This inspection can be abandoned if:

! the system is equiped with a failure-safe O - or CO-control, which causes

the shut-off of the burner due to an uncomplete combustion. or

! the system is equipped wiht a failure-safe O / CO- regulation, which

compensates the tolerances of the combustion. or

! it is guaranteed that the relevant operating mode gets as much excess air

over the full range, that the tolerances of the FMS do not have any effect. or

! the parameters of the FMS are set that way, that the tolerances to air

deficiency are 0 digits, i.e. there are existing only tolerances to excess air.

___________________________________________________________________

If You abandon the inspection of the shut-off limits due to one of these measures, You have to check the effectiveness of this measures, i.e. the O / CO- regulation respectively O / CO- control the stability of the

Due to the evidence of conformity to public and inspection authoroties and quality management , liability reasons etc. we would therefore strongly recommend that You always document the run to shut-off limits. You will find an example protocol in the appendix page 158. ___________________________________________________________________

___________________________________________________________________

Repeate this methode for all relevant operating modes (curve sets). As the case may be the above described inspection has to be executed in direction excess air instead of direction air deficiency if You cannot ensure that with the adjusted limits direction excess air, the flame burns reliably and stably and no CO arises from excess air. ___________________________________________________________________

The correction value can now be changed at will with Channel key 1 (6), with burner on. The manually selected correction value is maintained until the selector switch (2) is turned to some other position, or normal correction is activated by pressing Channel key 2 (4) downward. Adjustment of the correction range is possible via parameter 517 (with the burner operational). In the event of several fuels (curve-sets), the range can also be adjusted individually for each curve-set and channel via parameters 517 to 596 (expert level). To ensure that with deactivated O2-control the tolerance to the air deficiency side is not growing, the Parameters 917, 918 and 901, 902 have to be set to the corresponding value. This value depends on the selected correctional mode. Empirical formular (+correctional mode x 10.)-100 Example 1:

correctional mode +60/-40 Z the parameters have to be smaller than 500, i. e. every value

between 0 and 500 creates an exceed air ( 600 would correspond to the setpoint curve)

Example 2:

correctional mode +70/-30 Z the parameters have to be smaller than 600.

Tolerance limits direction The parameter values direction air deficiency have to be known to run the test. air deficiency The factory settings of the relevant parameters are noticed on the

configuration button. ___________________________________________________________________

If during the commissioning the factory settings of the dead band and the monitoring bands were changed, this has to be documented externally. The entries on the configuration button have to be set to status quo in nonblurable permanet manner. ( par example with water proofed permanent marker)

___________________________________________________________________ Tolerances in direction air deficiency do not exist if the following parameter

settings are kept : Z For fuel channels and recirculation channels dead band in positive direction

Z For air channels dead band in negative direction

parameters 32 - 36 = 0digits Furthermore the "Band shift in the event of a change in power" (par. 709 - 712) must have the same value as the monitoring band of the respective channel in direction air deficiency (pa,r. 62 - 76) for there will be no tolerances in direction air deficiency in the case of changing power.

We recommend the documentation in the form of a protocol. This protocoll may be included in the setting protocols of the burner.

FMS Commissioning Tips & Tricks

Programming 1 point If no separate fuel/air ratio is to be set for the ignition point Aids (ignition load point) (selectable via parameter 4= 0 or 2), proceed as described here.

________________________________________________________

For safety reasons "Setting” mode permits direct access to the control elements with the burner running. It is therefore essential to follow the safety rules laid down by the burner manufacturer.

"Setting mode” with the system running must only be undertaken by trained and experienced personnel, whilst keeping a constant watch on the system.

________________________________________________________

The first point entered after clearing the memory is always the ignition load point. This need not be the lowest load point, it is possible to enter ones lower than this. At least 1 point must be entered in order to form a new curve. A subsequent addition up to 20 points is possible at any time, see "Adding points” on page 47.

Instrumentation When commissioning systems with the FMS it is recommended that several for commissioning 5K potentiometers with ready-made connections and at least 2 current

transmitters be always carried, (particularly where the continuous outputs are used).

The current transmitter should be adjustable in the range 0 … 20 mA. A voltage range of 0 … 10 V would also be advantageous in order to be able to simulate the continuous voltage output of the FMS.

In addition 2 multimeters (measuring ranges: current, voltage, resistance) should be to hand when commissioning.

FMS Commissioning Tips & Tricks

Adjusting load ratings individually - when load points are to be adjusted without programming

a complete curve

___________________________________________________________________

When adjusting individual points it is normally only possible to freely adjust the set-point values. This is done by running to the load value (figure appears after the value). The associated set-point can be adjusted. The figure, which shows that the change is admissible, appears not only right at the programmed load point but also in the range ± 3 points around this. When stored, however, the value actually displayed is adopted.

At each adjustment of individual points it is therefore possible to shift the load value by up to 6 points.

___________________________________________________________________

Procedure for shifting the load value:

Undertake operations as described under "Adjusting individual points” but shift the load rating as required, Set set-point value

Store

If the desired load rating cannot be achieved in one operation:

Repeat procedure

- Output point is now the last curve entered

Entering an initial curve Since, prior to initial programming, the set-point EEPROM contains a

standard curve that very probably doe not correspond to the actual conditions of the system (ranges, set-point values), the following procedure is recommended for the initial curve:

Make sure that the signal wiring is correct

- see Function test and Manual

Clear memory

Leave FMS at "Setting”

Have system started up without control release (terminal 4)

After pre-ventilation, enter ignition load point

FMS Commissioning Tips & Tricks

_______________________________________________________________

Approaching control During operation the compound approaches the control elements from one elements from one side side in order to compensate for the mechanical hysteresis of the valves,

approaching all set-points from above.

Exception: The top point is never overrun and therefore approached

from below.

When setting, care should be taken to approach the valves in the same way. As a result the system values in automatic mode are reproduced in exactly the same way.

___________________________________________________________________

Entering settings Selector switch (2) to "Setting”

Run to desired set-point from above

if accidentally running below this point

Run above set-point and re-approach from above

Entering top setting Selector switch (2) to "Setting”

Run to desired set-point from below

if accidentally running above this point

Run below set-point and re-approach from below

___________________________________________________________________

Only in this way will you reach the same valve position and hence also the same combustion values in setting as later during automatic operation.

___________________________________________________________________

Ignition delay when setting When the ignition point is entered for the first time the facility exists for

observing the ignition process by entering a delay time. To do this, the time needed to run to the burner sight glass and to the boiler end respectively must be set in parameter 759. As soon as the question "Really ignite?” is confirmed by pressing the acceptance key, this time expires. On expiry the ignition is released. This time operates only if the FMS is on "Setting”.

Pre-setting load automatically Parameter 4 can be used not only to select the separate ignition point but

also to determine whether the load default is to be automatically pre-set during setting. If this is the case the load points (in addition to the ignition point) are fixed at the values 200 (corresponding to 4 mA at the load input), 250, 300, 400, 500, 600, 700, 800, 900 and 999.

It is then possible to switch only between these points by means of the load rating switch position. You cannot run to intermediate values during setting.

Storing a point causes the load default to skip to the next value (unless this is already taken up). In this way a curve can be entered without shifting to load rating.

FMS Commissioning Tips & Tricks

Entering the compound curves ___________________________________________________________________ with the burner stationary In order to be able to program the FMS without a flame, the fan must be in

operation (at least where a speed-controlled fan is actuated by the FMS)

___________________________________________________________________ Apply 230-V signal to fan

- e.g. Bridge terminal 81 and terminal 89 on relay R 18 (caution: as a result, terminal 92 also receives a voltage)

Disconnect "Burner On” signal (terminal 2) so that burner does not start

Enter curve Connect fan actuation again (e.g. remove bridge)

Keeping the re-circulation The pre-ventilation behaviour of the re-circulation duct according to the damper closed in pre-ventilation technical regulations on steal boilers [TRD] is incorporated into the software of

the FMS. That is, the re-circulation dampers always open with a delay. If the system subsequently requires the re-circulation to remain closed during pre-ventilation, this can be achieved by means of the pre-ventilation limit parameters (parameter 346-350).

Clear range limits Selector switch (2) to "Clear memory” Press Acceptance

- Selector switch to Automatic

Select pre-ventilation limit parameter for the re-circulation duct Enter CLOSE position of the re-circulation damper

Have range limits re-entered through pre-ventilation Now the re-circulation damper does not open during pre-ventilation

Setting the pilot burner ___________________________________________________________________ (servicing mode) A special function is incorporated into the FMS in order to facilitate setting of

the pilot burner. (The control unit runs only until the stabilisation time (main valves do not open).

By doing this, up to 5 ignition attempts can be performed without prior flushing or leakage test. Only after 5 starts does automatic flushing of the boiler occur according to the times set on the FMS.

___________________________________________________________________ Selector switch (2) to parameterisation Select parameter 787 Set content to "1”

- Servicing modus is active

Selector switch (2) back to Automatic Set pilot burner

(to do this allow the burner to start quite normally) when setting is completed Reset parameter 787 to "0”

Switching the burner on again via the target value

____________________________________________________________

If possible, only reset faults via short reset, otherwise the maintenance mode counter restarts, i.e. another pre-ventilation occurs.

____________________________________________________________

If the integral output regulator is used and a negative value is entered in parameter 802, it is possible to achieve a situation where the burner is switched on accordingly via the target value.

BE indicates that the signal is present on terminal 2, and all other

signals = 0 If the FMS controls a flue gas damper, this opens. It is possible to switch to "Setting”.

ZÜ indicates that pre-ventilation is finished and the ignition position relay EZ pulls on. The FMS is in the ignition position, but the flame signal is

absent. Switching to "Setting” merely causes the mode display to switch to EZ. Programming is not possible in this mode.

GL indicates that the burner is on (terminal 8=1), but the control release is EG absent (terminal 4=0). The FMS therefore remains in base load position.

Switching to "Setting” merely causes the mode display to switch to EG. Programming is not possible in this mode

NA indicates that the FMS is in post-ventilation mode.

All signals = 0 All air ducts open. When the configured time has elapsed, the FMS changes to "AU” mode.

AU indicates that the FMS is "OFF”. All control elements closed.

Selector switch on "Automatic”, all signals = 0.

EI indicates that the mode selector switch is on "Setting”.

Single points can now be altered or new curves can be entered.

SL indicates that the mode selector switch is set to "Clear memory”.

By pressing the acceptance key the existing curve is cleared and a new curve can be entered.

EV indicates that although the mode selector switch is on "Setting”

it is nevertheless performing the pre-ventilation routine. These is a signal on terminal 3.

_______________________________________________________________

If the selector switch is on "Setting” and there is a "signal on terminal 3”, the FMS nevertheless maintains its control function. The setting mode (display "EI”) is only activated when the pre-ventilation is completed and there is a flame signal and control release. The FMS can therefore only be programmed when the signal combination corresponds either to the "AU” and/or "BE” modes, or when the signal combination corresponds to the "Automatic” mode.

This mode is arrived at if the burner is switched off during a programming sequence and then restarts. The programming can be continued by operating a switch (change to "EI” mode”). Flame signal and control release are present.

"ES" Mode Should the burner skip to "ES" mode whilst programming is in progress (set - control) ___________________________________________________________________

This mode allows the electronic compound to run within curve sections already entered and thereby facilitates setting. If the load drops by 40 points, the FMS skips to "ES" mode, thereby controlling the outputs automatically.

"ES" mode is also started if the selector switch 1 is set to load rating and the channel 2 switch is pushed up.

Interconnection with The FMS offers the optional facility for using 4 curve sets. 4 curve sets option In this case 2 curve sets are firmly assigned to oil operation and 2 curve sets

to gas operation. The curve sets are then selected via terminal 75 (fuel selection) and additionally via the fuel safety interlock circuits. ___________________________________________________________________ Fuel Oil safety Gas safety Curve set selection interlock circ.

Order:

CRC 16 of level 0: adjustable without password

1: adjustable by person commissioning 2: adjustable by burner/boiler manufacturer 3: adjustable only by LAMTEC 4: adjustable only by LAMTEC

1 oil safety time in seconds

2 oil safety time in seconds

1 gas safety time in seconds

2 gas safety time in seconds Pre-ventilation time in seconds

On the FMS without pilot burner the statement of the 2 safety time contains

safety time. The statement of the 1 safety time is then irrelevant.

Calling up running Selector switch (1) to set-point time meter

Press Acceptance (3) and keep pressed

- a moving text appears giving the following data:

- total running hours

- running hours on curve set 1

- starts on curve set 1

- running hours on curve set 2

- starts on curve set 2

____________________________________________________________

Where the 4 curve set or 8 curve set option is used the running hours and starts on the additional curve sets are also displayed.

____________________________________________________________

The sum of the curve set 1 running hours and curve set 2 running hours does not necessarily give the running hours value displayed in total. The total counter relates to the FMS running hours. It runs as soon as the unit is connected to a voltage (this also provides the basis for the fault history).

The single running time meters relate to the burner running hours. These run as soon as the burner is in operation with the respective curve set (flame signal to the FMS)

What happens in the event If the processor detects a fault, it runs the outputs in the programmed direction, of FMS fault e.g. air on, fuel off, re-circulation closed

The fuel solenoid valves close. The fault signal relay pulls on with a few seconds delay. Automatic restarting may be possible, depending on the nature of the fault.

___________________________________________________________________

Reading off a fault Red fault LED lights up

Selector switch to "Status”

- Fault code is displayed

Note code Press Acceptance

- Plain text message appears on display incl. running time meter reading up

- Load rating at the time of the fault is displayed (externally and internally)

Note load ratings

Resetting a fault Selector switch to "Status”

Left-hand switch up

- the fault is cleared unless the cause is still directly present.

Alternative: FMS: Emit terminal 3 signal briefly (min. 2 seconds) via external switch.

Fault is cleared!

Calling up fault history The FMS stores the last 10 faults with the associated running time meter

reading.

___________________________________________________________________

Selector switch (1) to Status

- Instantaneous status appears on display

Channel 1 switch (4) up

- last fault code appears on display

- associated running time meter reading appears on display

Press Acceptance (3)

- text and running time meter reading appears on display

Channel 1 switch (4) up again

- penultimate fault code appears on display

- associated running time meter reading appears on display

In this way the fault history can be browsed through by operating the channel 1 switch ___________________________________________________________________

If you are sure that there has been a voltage on the FMS at all times since the last fault, the time of the fault can be determined by means of the current running time meter reading and the current time.

O regulation

O regulation perturbed In the event of perturbations, a warning message is displayed and the

O regulator is deactivated. The specified base value "Without regulation” or

the one for "Air shortage” is set. The display shows the running text "O regulation perturbed”.

The burner is not shut down as a rule.

The corresponding error code can be called up by setting the selector switch to Status. A plain text message about the cause of error appears after pressing the Acceptance key (3).

Air shortage perturbation If the actual O value is significantly smaller than the target value and

corrective action by the FMS/VMS cannot rectify this error, the regulator is deactivated and the base value for air shortage errors is output. If desired, an air shortage burner shut-down can be triggered by the FMS/VMS. This is achieved by setting parameter 897 to 1.

The error code is H360, "Error shut-down by O regulator”.

Resetting O errors O errors are automatically reset with each new burner start-up. This is

permissible, since a 100% O measurement test is performed at each

start-up. Manual resetting of O errors is possible at any time, as follows:

Set selector switch (1) to Status

- FMS in O regulation mode?

If not, switch over to O regulation mode

by pushing channel key 3 (4) upwards.

Press the Acceptance key (3) and

- call up the cause of error (mandatory!) Push key 3 (4) upwards

Calling up O regulation Switch over to FMS/VMS mode (compound regulator)

Selector switch (1) to Status

Switch channel 3 down

- In this way the fault history can be browsed through by operating the switch channel 2

___________________________________________________________________

The display of O history disappears automatically after 5 sec.

O regulator faults lasting over 30 sec are stored. They are only stored in

the EEPROM once the fault is cleared up or the FMS leaves the operating mode Regulation or Base load.

- at terminals 82-86 a testing current has to flow inboth directions. Otherwise the relay module switches all outputs off during the selftest and the FMS gets faulty.

- Impendance at a supply voltage of 230V # 100 kOhm 110V # 22 kOhm

As the case may be adequate loads have to be connected (e. g. ohmic resistance or RC modue) Outputs, which are not switched off by the FMS ( e. g. ignitionv valve at start without pilot burner) doesn't need any load.

925 see display text

Relay module 660 R 0016 since version V4.3: One of the outputs, which are tested during burner start (teminal 82 - 84) has recognised a fault. To diagnose the faults H 921 and H 925, you may change to the diagnosis mode. The changing will be done with plugging or unplugging the jumper B on the relay module (see chapter "Diagnosis Mode" on p. 120).

Fault 371 The monitor output of the FMS constantly monitors the current flowing

(terminals 47 and 49), (only if set to "Internal Load"). A current must flow at all times if the monitor output is configured to "Internal Load". If the output is not used, the terminals must be short-circuited.

___________________________________________________________________

Check wiring

Measure current (Maximum apparent ohmic resistance 600W)

Short-circuit terminals directly

Reset fault ___________________________________________________________________

If the current can no longer flow entirely via the negative input (terminal 49) because of an external earth connection, this fault will occur even though the output current is correct.

FMS Fault Correction Load signal (D) Aids

Load signal does not show Cause: load transducer not on minimum the minimum value

Run transducer down manually

_____________________________________________________________________________________________________

Load signal cannot be changed Check whether fault present

if so

Rest fault (selector switch on status switch up)

if not

- current input poles reversed

_____________________________________________________________________________________________________

When changing a point, Load rating was not run precisely to the point previously programmed. "Err" or >20 point appears on the display instead of "Point" Repeat process

but this time

Run precisely to load rating

It is possible that the digital display shifts after the load rating, if

- the load rating is right at the edge of the adjustment range

- there are marked fluctuations on the connection leads

For this reason: Run load rating to the middle of the adjustment range (flashing number after the load rating)

_____________________________________________________________________________________________________

Load signal cannot be set higher Load potentiometer wrongly connected (middle reversed with outer) than approx. 500, although the or 5kS potentiometer runs the internal wiring of the configuration cards causes the FMS to expect a over the full range current signal as load default

Check wiring Check that the correct configuration jumpers are inserted,

if not, change them
