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).
