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.
2
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
th
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).
2
Connections for Interbus-S, Profibus, Modbus and CAN-
BUS 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

2
(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
2
regulator strategy, it is also possible to regulate burners with frequent load
changes.

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.

10
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).

12
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
st
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
nd
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.
th
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:10sec).Thisrestartcanbepreventedbysettingtheperiod
to0.
n the case of firing systems according to EN 676 the parameter must
be set to "0”.
Thestandardsettingiswithoutrestart.
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).
st
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
2
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
2
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

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:

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

The operator is alerted by the display (running text) that the output regulator

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).
