4 Operating Description
4 Operating Description
(for specimen diagrams, see Appendix 9.8 Process Sequence Charts) A signal is first fed to terminal 58 (Burner On) indicating when the burner is to start.
The ETAMATIC then interrogates the boiler safety interlock circuit or the common safety inter­lock chain (ETAMATIC) and the contact of the air pressure monitor. If it does not detect an "OK" condition, the text of a corresponding message appears and the operating control stops.
If all signals are OK, the fan output is activated and the ducts run to their bottom stop as a check.
Once all channels have reached their bottom stop, they open for aeration. The leakage test runs in parallel (gas operation only).
In the case of control elements the aeration is used to enter and/or test the range limits. After reaching its top position, the fuel control element runs back into the ignition position. All other channels remain in open position. The ETAMATIC then interrogates the air pressure monitor. If this signal is OK, the parameterised aeration time runs. If a channel is configured for re-cir­culation, it opens with a time-delay. On reaching the parameterised re-circulation delay time, the aeration time stops. As soon as the re-circulation channel has reached the aeration posi­tion, the aeration time is resumed. When this time has expired all the channels run to the pro­grammed ignition position (re-circulation fully closed). After the lapse of the aeration time, all channels run to the programmed ignition position (recirculation closed)
4.1 Starting without pilot burner
The main valves open and together with the ignition transformer remain activated for the du­ration of the safety time. During this time the flame signal appears.
4.2 Starting with pilot burner
The ignition valve and main gas 1 (in gas operation) or the ignition valve alone (in oil operation) run open. The pilot flame forms and the flame detection detects the flame. The flame detection sends the signal to the burner control device.
On expiry of the 1 time) the pilot burner burns alone. Then main gas 2 or the oil valve opens and remains acti­vated in parallel with the ignition valve for the duration of the 2 closes again at the end of this period.
3 seconds after ignition, all channels run to the programmed base load point. The ETAMATIC remains in base load position until control release is given.
After control release the ETAMATIC follows the power control unit’s default setting. A shut off follows the cancelling of the signal of the terminal 58. The main valves close. In gas
operation, first main gas 1 and second main gas 2 closes with a delay of approx. 5 sec., in order to allow the test line between the solenoid valves to burn out. In the event of a fault shut­down, both close immediately.
If configured for post-ventilation, the air channels open again for this period. Thereafter the ETAMATIC is in the "OFF" mode.

Category = channel configuration and broken wire detection
In this parameter you define the type of actuator the respective output channel controls. This indirectly deter­mines the channel’s behaviour at pre-ventilation, at band shifting, at changes of the burner-firing rate and at drift compensation. This possibly may, affect special functions (e.g. if the channel is configured to recircula­tion or flue gas).
0 = Channel OFF (broken wire monitoring and indication in the display are active further on / channel switch off with P 366 - P 373) 1 = recirculation 2 = fuel 3 = combustion air 4 = flue gas 5 = mechanic compound 6 = atomizer steam (like fuel, but without pre-ventila- tion of the channel: switch off determination of range limits)
Behaviour of the actuators with FMS: steam = Remains CLOSE until the pre-ventilation time
has expired. After that the actuator runs to ignition position. REZI = Runs OPEN after the configured pre-ventila- tion time, even if terminal 6 has a signal. In reg- ular operation terminal 6 must have a signal. flue gas = Runs completely open in BE and remains open until ignition. Then the actuator runs to compound. At start without VO, ignition starts not until flue gas is completely open. mech. compound = Acts like air in VO.
Behaviour of the actuators with VMS: steam = Remains CLOSE until the pre-ventilation time
has expired. After that the actuator runs to ignition position. REZI = runs open to the configured number of points in VO = position, which the allocated air actua- tor must have reached (terminal 6 has signal). flue gas = Runs completely open in BE and remains open until ignition. Then the actuator runs to com- pound. At start without VO, ignition starts not until flue gas is completely open. mech. compound = Acts like air in VO.

delay with an air channel during pre-ventilation. There­fore an air channel is assigned to the recirculation flap (see P 428). The opening of this air channel now deter­mines the moment, when the recirculation flap shall open. Set in this parameter the number of digits the air channel has to reach, before recirculation becomes active.

As soon as the ETAMATIC is supplied with voltage, it attempts to drive the actuator motors to the lower limit of the factory set curve. If the end-bearing's limit switches are not properly ad­justed for this, the motor may hit the actuator's mechanical stop
WARNING! This may 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 may be readjusted later.

6.11.1 Setting the Correction Range and the Correction Mode
The correction value (control signal) transmitted to the electronic compound is 0…100% with a resolution of 0.1%. 0% corresponds to maximum excess air, 100% to minimum excess air. Factory setting is a neutral value of +60% to -40%. This means that the control range in the direction of excess air is 60% and in the direction of air deficiency it is 40%. The main focus of this base setting is that contamination of the burner and the boiler during the operational period would result in an increase in the installation's flow resistance. Thus a larger control range in direction excess air could be an advantage.
If another correction mode is selected via parameter 437, the base setting also changes at the same time:

Correction type 2 is used where the correction is applied to a non-linear control element, e.g. air damper. The curve's slope is taken into account before calculating the correction. A flatter curve results in a smaller correction range, whilst a steeper curve results in wider range.

7 Internal Burner Firing-rate Controller
7 Internal Burner Firing-rate Controller
7.1 Purpose
The internal power control unit allows the inserted burner firing-rate position to be continually determined for a specified set-point value (e.g. as a function of temperature or pressure) by comparison with the actual value. This position will be transferred to the electronic compound as a default value.
7.2 Brief Description
The integral power control unit is a PID controller with special combustion engineering func­tions. You can use it as a fixed value control or as a control by atmospheric condition. The fol­lowing signals can be pre-set:
Actual value (temperature or steam pressure)
Outside temperature or other analog signal for setpoint shift (only on control by atmo­spheric condition). The ETAMATIC must be equipped with the optional hardware for con­trol by atmospheric condition.
Setpoint switching (via floating contact). The burner-firing-rate controller releases the combustion internally.
Combustion is triggered internally by the power control unit.
7.3 Limit Ranges
You must set limit values in the parameters, which switch the burner on and off. If the burner shuts down and the actual temperature has not yet reached the switch-on threshold again, a display informs the operator that the power control unit refuses a start-up.
7.4 Light Writing "Actual Temperature is too high"
Press key 12 HAND to override this and start the ETAMATIC, if the maximum temper­ature has not exceeded.
Press key 12 HAND again to switch back to automatic mode.
NOTICE! The limit values should always be entered in the form of a difference from the set-point value.
7.5 Enter setpoint of power control
Up to software version A3i1023 you can change the setpoint with parameterisation only. From software version A3i1023 on you can change the setpoint of the firing-rate controller. This function works only if the burner is in operation
Press key 9 and 6 simultaneously the setpoint in the display is blinking.
Use keys 4 and 5 to change the value.
52
7 Internal Burner Firing-rate Controller
Press key 11 ENTER to confirm the new value
Press keys 7 and 8 simultaneously to leave this mode without changes.
WARNING! If you change the setpoint, regard that also the on and off switchpoints are shifted, because
they are defined as a difference value to the setpoint
7.6 Input Signals
The analogue inputs can be preset in various forms. Actual value:
as 0/4-20 mA current signal, terminals 4 and 5 (+), 3 (-)
as non active current signal 4...20 mA (two-wire connection), terminal 23, + 24V supply, terminals 4 and 5 input
as 0...10 V voltage signal
as 0...5 k resistance signal, terminal 4, 5 and 6
directly as PT 100 terminal 21, 20, 19 as three-wire connection
Outside temperature (setpoint-shifting) - only available if ETAMATIC has the option "control by atmospheric condition"
as PT100 as three-wire connection, terminals 39, 40, 41 (default)
as 4...20mA current signal, terminals 39 (-) and 40 (+), special option, please order separately
as non active current signal 4...20 mA, term. 23 + 24V supply, terminal 40 input
7.7 Operating Description
The start of the burner is described as above. Only the burner start release must be forthcom­ing from the power control unit, i.e. the actual value must be correspondingly below the set­point value.
The burner starts only when the "Burner On" detects the release are forthcoming from the load control unit. Only when the burner is ON and the "Control release" signal has been given does the power control unit function. The load default for the compound is then set via the integral power control unit. It is dependent on the difference between the actual and the set-point value and the adjusted control parameters. Should the actual value exceed the adjusted maximum value, the power control unit switches off the combustion.
The power control unit is only active in the "automatic" mode.
7.8 Steam Pressure
If you get a steam-pressure signal from a pressure transmitter on terminal 3, 4 and 5, you must short-circuit the PT100 input at terminal 19 and 21.
53
7 Internal Burner Firing-rate Controller
7.9 Control by Atmospheric Condition
If the burner firing-rate controller is configured as "controlled by atmospheric conditions" the setpoint value can be shifted between the parameterised setpoint minimum and setpoint max­imum by connecting another PT 100 temperature sensor to the terminals 39, 40 and 41. In the realize by atmospheric conditions, the outside temperature is a component of setpoint calcu­lation. This allows the operator to enter a minimum and a maximum setpoint, between which the outside temperature can determine the final setpoint value.
With the option "Control by atmospheric condition" you may realise an external setpoint pre­setting.
7.10 Set Point Changeover
You can switch the setpoint with the input "setpoint switchover". If you use a version with fixed setpoint value it is possible to select one of the two values, which are entered in the parame­ters 796 and 798 with this contact.
If you have activated the control by atmospheric conditions additionally, you can select be­tween two pairs of limit values (see control by atmospheric conditions and limit ranges). The parameters for setpoint 1 (for setpoint switching) and setpoint min. 1 (for control by atmo­spheric conditions) are equal. Likewise the parameters setpoint 2 and setpoint min. 2. The cor­responding content is assigned according to the configuration.
When activating the "control by atmospheric conditions” option and setting the adjustable pa­rameters, you may realise an external setpoint default. In other words, the setpoint can be ad­justed manually or automatically via a potentiometer (or switched through resistors). By connecting a change-over switch, you can implement a night-time reduction instead of control by atmospheric conditions. A control by atmospheric conditions and a night-time reduction can be realised simultaneously, if you combine the control by atmospheric conditions with the set­point switching.

7.11 Start-up Sequence
The firing-rate controller has a startup circuit, in order to slow down the burner's start firing­rate. The startup circuit is run during each new burner start. The internal firing-rate is held at a value (P 792 adjustable by the user, for as long as the boiler is cold (actual value is below a user-adjustable limit, P 791). If the controller’s actual value is equal to or larger than the pa­rameterised startup maximum temperature, this startup circuit is canceled.
In order to prevent a situation where an excessively large demand on system output, the boiler temperature necessary to cancel the startup circuit is not reached, a startup timer is also trig­gered in parallel (this timer can also be adjusted by the operator, P 793). Once the internal firing-rate reaches the parameterised startup firing-rate, the output is increased linearly step­wise up to the maximum firing-rate. The slope of this linear increase is calculated from the pa­rameterised startup time.

7.12 Thermostat and Control Range
The thermostat function switches the burner on and off on the basis of the temperature and/ or pressure value, but only when burner is released by the start signal. The control range is formed by entering the controller set-point value and the parameters P 802 (switch-on point), P803 (upper control range) and P 804 (burner OFF). The cut-off hysteresis is divided into 2 ranges. The first part lies above the set-point and forms the upper control range. The second part lies below the setpoint and forms the lower control range.
The control range may lie asymmetrically around the setpoint. The power control unit functions within the upper and lower control range according to its set-
tings in the parameters and the default values. If the actual value of the control unit reaches the shut-down range, the base load request is
emitted. If the control unit’s setpoint exceed the shut-down range a control shut-off occurs. This is done by internal processing. If the actual value drops below the lower control range, a re-start can occur.

7.16 Control Range
The control range lies around the setpoint. The content of the "Burner on" parameter is sub­tracted from the setpoint value to form the switch-on value. The value of the "Upper control range" parameter (P 803) is added to the setpoint value to form the upper limit of the control range. The control range may therefore lie asymmetrically around the setpoint.The shut-off range is upwardly limited by the "Burner off" parameter (P 804). The parameter is added to the setpoint value, too. If this value is exceeded, the burner is shut off.
The range between "Upper control range" and "Burner off" forms the shut-off range. If the ac­tual value reaches this range, the compound runs at base load. It also follows from this that the value in "Burner Off", is generally greater than that in "Upper control range". Otherwise there is no shut-off range and the burner is immediately shut off on reaching the limit. The burner 'ON' switching point also can be located above the setpoint. In this case the pa­rameter 802 has to be set negative (<0).
7.17 Checking of the Safety Limiter
To check and to test the Safety Limiter, the setpoint must be changed. In this case the shut­'OFF' range is offset, too and the Safety Limiter can be overrun in manual mode.

8 Control Mode
8 Control Mode
The firing-rate controller endeavours to bring the actual value into line with the setpoint value. In so doing, a direct correlation is assumed between the internal firing-rate and the boiler tem­perature, i.e. the greater the internal firing-rate, the faster the boiler temperature rises. Should the curves be programmed differently, the firing-rate controller will not function. Four parameters determine the control action.
Adjustment time
The adjustment time determines at what intervals the deviation is checked and the new adjustment is determined.
P term
The proportional term acts directly on the deviation, that is the difference between set­point value and actual value. P > higher step response
I term
The integral term is calculated from the instantaneous deviation and the previous devia­tion from the setpoint value. I > faster approximation to the setpoint danger of overshooting!
D term
The difference term is calculated from the variation of the actual values. It has acceleration and respectively slowing effects.
In practice the adjustment of the PID-controller orients itself on the given controlled system. With the characteristics of the controlled system you try to deduce acceptable data, i.e. the values are defined experimentally
P term, I term, D term are added together and act as adjustment on the load default for the compound control unit. The value is added up, starting from the instantaneous internal load.
As long as the actual value is below the setpoint, P term and I term are positive, that is to say both these term will increase the load default.
Only the D term is negative in such a case (assuming that the boiler temperature is rising). Use the D factor sparingly because it leads to a higher burden of the actuators.
In order to avoid excessive overshoot during burner start-up, the parameters should be adjusted to achieve a suitably large D-term.
If, despite a large setpoint deviation, the burner is not run at full load or base load, the P term should be increased.
The longer the adjustment time, the quieter the group. However, this also increases the actual value's deviation from the set-point value and leads to slower adjustment.

8.2 Leakage test
The leakage test checks whether the main gas valves are leak-tight. 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 without pressure when starting (gas pressure > min. = 0). The ETAMATIC checks this. Main gas 1 is then opened shortly 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 previous fault shut-down), main gas valve 2 opens first. The leakage test line is vented (into the combustion chamber or over the roof, depending on the system; for suggested circuit, see Appendix). It is checked, whether the line remains pressureless for 30 seconds. Otherwise the procedure is, as de­scribed previously.
The leakage test is performed before ignition. The pressure monitor for the leakage test line must be connected to "Gas pressure >min" input
(terminal 47). It also monitors the minimum pressure during operation. If another minimum pressure should to be monitored during operation, the pressure monitor is, to be looped into the gas safety interlock circuit, for this purpose.
However, the test line must be designed to ensure that the test time of 30 seconds per valve is sufficient for reliable detection of a 0.1% leak of the fuel gas consumed at maximum com­bustion heat output, but at least 50 dm

8.2.3 Standby
Standby mode
In this mode the ETAMATIC enables a switchback to ignition burner mode. The burner re­starts without pre-ventilation.
You can activate „standby mode“, if the internal firing-rate controller is active or if an external input or output command can be connected to LSB module or fieldbus (see parameter 812, level 4).
As soon as the burner firing-rate controller detects that a shutdown of the burner would be nec­essary, it closes the contact at the LSB or the appropriate bit will be set to high via field bus. This doesn’t lead to a shut down as it was up to now. Stand-by mode will be activated instead.
The stand-by mode drives the load value to ignition point and waits for ignition acknowledge­ment. Ignition valve and ignition transformer are switched on first. The recirculation channels run to CLOSE position. Ignition position has to be active. After an idle time (stabilisation time) the valve gas 1 (if fuel = gas) is closed for purging the gas system.
Afterwards all fuel valves but the ignition valve stay closed. If you have set the performing of a leakage test after operation at fuel gas, it will be started now.
Afterwards the ignition transformer will be shut off. Only the ignition valve will remain open.

Specification of the burner sequencer function "Standby Mode"
The sequencer is now in stand-by mode with active ignition flame. Ignition position acknowl­edgement must apply all the time.
As soon as one of the following incidences happen, the parameterised ignition sequence of the fuel is executed without switching on the ignition transformer:
boiler pressure or boiler temperature have lapsed to that point, where the burner would
start again (with internal firing-rate controller) – as soon as the LSB contact (terminal 1) opens again – as soon as the command is transferred via fieldbus This may occur after leakage test, before operation, with fuel gas and without the transformer
leading time (analogue changing via pilot burner ignite the new fuel)
Fig. 8-6 Sequence at oil operation
WARNING! At combustion plants with just one flame detector, you have to ensure, that the main flame is
always ignited by the pilot flame. Otherwise You have to use one flame detector for the main flame and one for the pilot flame.
If the "Burner on" signal will be removed during stand-by mode, the ETAMATIC switches off. This shut-off proceeds like a shut-off out of the mode base load/control mode with all it’s pa­rameterised procedures.
In oil operation the output for the oil pump stays active. LSB module address 31 input 1
WARNING! Since it's not sure how long the standby mode applies, a separate ignition flame monitoring
must be approved for continuous operation, or main flame and ignition flame will be monitored together with one flame scanner, approved for continuous operation.

9.2 Flame Monitoring
9.2.1 Integral flame monitoring (option)
Purpose
The integral flame monitoring system is primarily used for standard applications (e.g. oil or gas flames at a burner in a combustion chamber) because of it’s limited adjustment possibilities.
NOTICE! We recommend the LAMTEC flame monitoring systems (like F 200 K 2 or f 250 with FFS 05
or FFS 06), if you have other requirements for the flame monitoring (e.g. combustion of coal dust). You will find information on this devices in the corresponding manuals (DLT7600, and DLT7502 / DLT 7503).
The task of the flame monitoring device is to scan the burner’s flame in combustion plants un­affected from any condition in the combustion chamber (e.g. glowing nogging) and to release the closing of the fuel valves at a flame blow out with an internal control command of the burn­er control system.
The flame monitoring device has the following tasks: – Scanning the burner flame unaffected of the conditions in the combustion chamber (e.g.
glowing nogging)
internal release of the control command to close the fuel valves at a flame blow out with
the burner control system You may connect the following LAMTEC flame sensors: FFS 06, FFS 05 UV, FFS 06, FFS 06 UV (with the following sub-types FFS 05, FFS 05 UV in
version for Ex zone 1 or Ex zone 2).

Self Monitoring
Signal processing with two separately constructed and alternately activated transmission
channels. – Continuous comparison of the output levels for anticoincidence. The transmission range of the digital frequency analysis covers signal transmittance between
10Hz or 25Hz (factory configuration) and 200 Hz. Mains frequency signals and their harmonics are filtered, with a filter bandwidth of 3 Hz.

9.2.2 General Information of the Optical Flame Monitoring
Notes on assembly and installation The processes that occur during combustion give rise, inter alia, to a pulsing component of
the flame's radiation (flame flickering), whose oscillations (flame frequency) are relatively rap­id at the flame's root (i.e. near the burner's mouth) and become slower toward is tip.
For individual monitoring, the flame sensor should be aligned in that way, that the first third of the flame is observed.
The flame sensor's correct alignment is essential for achieving a high degree of availability and/or selectivity.
WARNING! We recommend to lay the supply cable, including their extension, on separate cable trays to
keep mains and control lines as well as high-energy power lines and equipment separated from each other (e.g. ignition lines, ignition transformer, electrical motors, contactors). More­over, avoid any parallel cable routing together with mains cables in trays

The sensor's circuit components are located on PCBs in a cylindrical housing with a spray­proof, axial optical aperture.
The sensor meets the requirements of protection class IP 65. Optical flame sensor FFS 06/FFS06-UV (standard for ETAMATIC) The sensor's circuit components are located on PCBs in a cylindrical housing with a spray-
proof, lateral optical aperture. The sensor meets the requirements of protection class IP 65. The computing circuit for all sensor types is located in the ETAMATIC. Cabling from the sensor to the ETAMATIC is 5-pole, static-screened with the sensor housing's
potential (operating earth connection), a six commisioning.
WARNING! If the ETAMATIC is used with an integral flame monitor, terminal 53 may not be connected to
any other components
th
cable is for measuring the flame signal during
Optical flame sensor FFS 05 … ; FFS 06 The optical flame sensors are supplied together with a connecting cable of ca. 2 m length. The
line between the sensor and the flame monitoring unit may be extended up to a distance of 500 m. For implementing an on-site extension we recommend a separate screened, five-wire extension cable that can be connected to the sensor cable via an FG 24 (with ex-applications) or FG 21 connector box, e.g.
cable type: LiYCY (blue, red, green, yellow, white) 5 x 1 x 0.5 mm
WARNING! If the option "integral flame monitoring" is deactivated subsequently in the ETAMATIC (e.g. an
external flame monitoring should be used), up to base version 4.0 the automatic flame guard plug-in card has to be removed from the ETAMATIC, from base version 5.0 on the bridge 450 (beside the 96-pole plug) has to be switched.
The cable's screening may not be used as a low-frequency carrying operational link. The sen­sors should be so mounted at the inspection aperture, that the burner's flame is properly vis­ible across the entire combustion facility's "operating range”. For selective monitoring, the inspection aperture should be so placed that the sensor covers the monitored flame's root (near the burner's mouth). Attention should be paid to the fact that with extended tube collars the part of the flame, which is covered by the sensor, becomes restricted. If necessary, the inspection aperture should be sealed with a suitable protective glass sheet.
9.3 Avoiding EMC Effects
2
(AWG 20)
The proper installation normally prevents from the EMC-adverse effects. In exceptional cases it may be necessary by not traceable and /or not removable sources of interference to find an adequate grounding point for the shielding.
1 In exceptional cases it is possible, that through the protected earth an interference level is
injected into the shielding. Unmotivated fault shut-downs (especially with low wanted sig-
72
9 Appendix
nal) or temporary extraneous light may occur. In this cases the following may help beside the fault clearance of the protected earth.
a disconnection of the flame sensor shielding from the protective earth terminal at the
ETAMATIC and the connection with the GND of the flame sensor (terminals 22 or 44)
In rarely cases the shielding may be disconnected like described in section a) and the
sensor housing may be grounded at the burner plate.
2 Adverse effects through coupling into the laid cable may be eliminated normally only with
the correct laying and in some cases with an adequate grounding point.
3 Adverse effects straight to the flame sensor may be suppressed with the reduction of the
sensitivity when there is a sufficient flame signal.

9.7 Tips and Tricks
Oil pressure does not build up in time. Extending the transformer pre-energise time (P 782) starts the pump sooner.
9.7.1 Set pilot burner
Setting the "Service mode" parameter (P 787) causes the ETAMATIC operating program to run only up to the stabilisation time. But up to 5 successive starts can be attempted without pre-ventilation and without leakage test. After setting the pilot burner, set parameter back to 0
NOTICE! Resetting a fault with a total reset clears the internal counter for the service mode. The next
start-up, pre-ventilation again.
9.7.2 Post-measurement of safety times
If it is required to measure the installation's safety times at a later time (e.g. as part of an in­stallation's acceptance tests), it is not sufficient to disconnect the magnetic valves before start­up. This is recognised by the ETAMATIC's self-testing circuit, and results in emergency shut­down.
Disconnect the ignition position's acknowledgement function (term. 46). Start-up and wait until the ignition position is reached. On the self-test's completion (ca. 5 sec), the magnetic valve can be disconnected. Reconnect the ignition position acknowledgement function.
The installation starts up.
