Gas Burner Safety Control DKG 972

For 2-stage atmospheric gas burners

Flame detection:

— Ionisation probe

— Infrared-flicker detector IRD 1020.1

— UV flame sensor UVD 971

INTRODUCTION

The burner control box DKG 972 controls and supervises

atmospheric burners for gas. They are approved and certified

according to the applicable European standards and

regulations.

The microprocessor-based programming sequence ensu-

res extremely stable timings independent of voltage varia-

tions, ambient temperature and/or switch-on cycles. The

built-in information system not only provides a continuous

monitoring of the actual state of the box (very helpful es-

pecially for monitoring the start-up phase) but also informs

about the cause of a possible lock out. The lock out cause

is stored in such a way that it can be retrieved even after a

power failure.

The control box is designed for maximum safety in case of

fluctuations in the voltage supply. If the mains voltage drops

below the permitted level, operation is interrupted and the

control box automatically prevents the start sequence from

being repeated. In this way, the safety of the system is not

put at risk by a drop in the mains voltage. This low-voltage

protection works not only during start-up but also perma-

nently during operation.

CONSTRUCTIONAL FEATURES

The control box circuitry is protected by a flame resistant,

transparent plug-in type plastic housing. A central fixing

screw locks the control box to the wiring base.

The plug-in control box incorporates the microprocessor

based timer, flame check and reset circuits.

Manual reset from lock out and set to lock out is provided by

a push button with an integrated LED information system.

A variety of cable entry points provides complete flexibility

for electrical wiring.

The wiring base S98 is equipped with spare- and extraterminals

and allows together with a variety of cable entry points utmost

flexibility of electrical wiring.

The DKG 972 are compatible with the TFI 812.

Different are only the pre- and post-ignition times.

Honeywell DKG 972-N mod.10

Honeywell Satronic DKG972-N mod.10 предназначены для контроля и управления работой газовых горелок, дизельных горелок,теплогенераторов, газовых котлов

Для 2-х ступенчатых атмосферных газовых горелок

Особенности Satronic DKG 972-N mod.10:

— Программирование последовательности операций с помощью DKG972-N mod.10 гарантирует высочайшую стабильность розжига независимо от колебаний напряжения, окружающей температуры и/или циклов включения.

— Встроенная информационная система не только обеспечивает непрерывный контроль реального состояния устройства (что особенно важно для мониторинга фазы запуска), но сообщает о причине возможного автоматического отключения.

— Информация о причине отключения записывается в энергонезависимой памяти.

— Автомат розжига обеспечивает максимальную безопасность в случае колебания напряжения электросети. Если напряжение питания упадет ниже допустимого уровня, то операция прерывается и автомат блокирует повторную попытку запуска. Эта защита от падения напряжения действует не только при запуске, но и постоянно во время операций.

— Защелкивающийся прозрачный корпус из огнеупорной пластмассы, крепится на монтажной плате фиксирующим винтом.

— В корпусе автомата размещены микропроцессорный таймер, детектор пламени и электросхемы сброса.

— Кнопка со встроенным светодиодом предназначена для блокировки и ручного сброса при блокировке.

В случае неисправности светодиод зажигается и горит немигающим светом. Каждые 10 секунд это освещение прерывается флэш-кодом, указывающим причину ошибки, поэтому до сброса повторно выполняется следующая последовательность.

honeywell DKG-972 задумки

Добрый день . Есть котел водогрейный-ROSSEN. автоматика собрана на honeywell DKG-972.Все хорошо. было бы. Если котел не отключался после набора температуры. При недостаче температуры котел переходит на большое пламя. когда достигается заданная температура происходит переход на малое пламя. если и дальше происходить набор температуры происходить полное отключение. Это не хорошо. было бы лучше если котел оставался на растопочной горелке. Потому что в основном сбой происходят при розжиге горелки.Надо бы оставить растопочную горелку, но не могу оставить защиту по пламени для растопочной горелки.подумаем вместе ,как это можно сделать.

Обратиться с претензией к производителю.

Ваш покорный слуга делал всевозможные доработки автоматики таких котлов. Вот, например: http://kotelna.tk/index.php?put=1-1-7-18 (внизу страницы)

Последний раз редактировалось Stentor; 02.07.2020 в 18:59 .

Кажется, я понял, в чём дело. Там есть и регулирующее реле температуры, выключающее горелку, и аварийное?
Наверное, изготовитель котла поместил контакты регулирующего реле температуры, выключающего горелку, в цепь электропитания «топочного автомата»:

. А по логике, это реле должно размыкать только электропитание газовых клапанов.

Последний раз редактировалось Stentor; 02.07.2020 в 18:58 .

Это обман потребителя. Автомат горения одноступенчатый, первая ступень предназначена только для розжига, чтобы не было хлопка.
Автомат горения для двухступенчатых горелок должен управляться двумя термостатами, первой и второй ступени. Здесь и предельный, и регулирующий термостаты тупо рвут питание автомата. Различие только в том, что предельный термостат с блокировкой.
Ничего здесь сделать нельзя.

Надо просто пару проводов перебросить.

Последний раз редактировалось Stentor; 02.07.2020 в 18:58 .

Уверены, что получится? Не будет аварии по пламени на малом горении? Производитель до этого не додумался?

Не додумался? А много ли он думал?
Да там в схеме ошибки прямо в глаза бросаются.

Последний раз редактировалось Eugene.A; 22.09.2019 в 17:38 .

пока меня тут не было уйму постов накидали. Это уже хорошо.
Конечно. разработчикам все по фиг. им бы только котел отключался по любому случаю. Было бы и то большим плюсом. если бы они на этот котел поставили нормальный трансформатор розжига,а не эту игрушку от бытового котла.
Ладно а теперь к вопросу. Хорошо что ещё Eugene.A схему залил. По схеме видим что второй выход ТРМ командует с большим и малым пламенем. Если цепь есть идет большое горение если нет то остается только малое. А вот первый выход ТРМ дает разрешение котлу работать до предельный температуры. Которую мы сами же задаем. Это предел рабочей температуры. а аварийный предел контролируется с термостатом. И так если разрывается цепь на первом выходе ТРМ на 9 ую клемму контроллера перестает поступать напряжение. И котел уходить в режим ожидания. Меня интересует что там внутри контроллера твориться за этой 9 ой клеммой?

1.2 Lock-out diagnoses
In case of a failure the LED is permanently illuminated. Every
10 seconds the illumination is interrupted by a flash code,
which indicates the cause of the error. Therefore the following
sequence is performed which is repeated as long as the unit
is not reset.

2. Flame detection
The following types of flame detectors are suitable:
– Ionisation probe, temperature resistant material, well
insulated (material and insulation same as for ignition
electrode).
– Infrared-flicker detector type IRD 1020.1 with mounting
flange M 93 or the UV solid state flame sensor UVD 971.
Flame detection using an ionisation probe is only possible
in conjunction with mains supplies which provides a neu-
tral earth connection.
Connecting the IRD 1020.1 or UVD 971 the correct wiring
has to be observed.
2.1 Stray light monitoring
The stray light check is performed at the end of the pre-
purge time for thr duration as mentioned in the table of
timings.
APPLICATION FEATURES
1. Information system
The information system is microprocessor based and re-
ports on all aspects of burner control box operation and
flame supervision. It informs continuously about the actual
programming sequence the unit is just performing. Besides
monitoring of the programming sequence it also allows to
identify errors during start-up of operation without any
additional testing devices. The automatically performed
diagnosis is a valuable tool which facilitates service/
maintenance work and therefore saves costs. The analyses
of the error cause can be done directly on stage or if not
possible afterwards as the lock out reason is stored in a non-
volatile lock out mode memory.
The information system communicates with the outside
world using a LED (the used Flash-Code is similar to the
Morse-Code). The messages are optically transmitted by a
appropriately flashing LED. Using an additional terminal
(optional), the messages can be recorded and displayed in
easy readable form.
1.1 Programming sequence display
The built-in microprocessor controls not only the pro-
gramming sequence but the information system too. The
individual phases of the programming sequence are
displayed as Flash-Code.
The following messages can be distinguished:

3. Lock out and reset
The unit can be reset or brought into lock out mode in two
different ways:
Internal
In the lock out case the unit can be reset by pushing the built-
in button meaning a new start-up cycle is performed.
External
Instead of using the built-in lock out button the same
function can be achieved by using an external button which
connects terminal 9 with A (see also circuit and block
diagram).
If the  pushputton (internal or external) is pressed during
normal operation or during the start sequence for more then
3 sec. and afterwards released, the control box will perform
a shutdown.
Please note
The unit can only be brought to lockout mode or
be reseted if power is applied to the unit.
4. Low-voltage protection
at 220 / 240V (110 / 120V) nominal voltage
The mains voltage has to be more than 187 V
eff
  (94 V
eff
 ) in
order to allow the unit to perform a start-up.
The mains voltage is not only monitored in the start-up
phase but also permanently during operation. If the voltage
drops below < 160 V
eff
  (80 V
eff
 ) during start-up or run time
the control box proceed to safety shut-down and goes into
a waiting status. If the voltage rises again, the control box
performs automatically a start-up as soon as the mains
voltage is > 187 V
eff
 (94 V
eff
 ) .
5. Safety
The design and control sequence of the DKG 972 controls
will comply with the currently applicable standards and
regulations (see also TECHNICAL DATA).
6. Mounting and electrical wiring
Wiring base:
– 3 earth terminals with additional terminal for burner
earthing
– 3 neutral terminals with internal permanent connection to
neutral terminal 8
– 2 independant spare terminals (S1 and S2)
– extra terminals A, B and C are standard (wiring base S98
12-pin)
– 2 slide-in plates and 2 easy knock out holes plus 2 knock
out holes in the base bottom faciliate the base wiring
Please note
To assist trouble-free operation the main neutral
connection terminal 8 in the wiring base must be
fully tightened. The terminal screws are already in
the undone position. To connect a wire to the
terminal, the screw only needs to be fastened.
General: The control box and detector probes should not be
subjected to excessive vibration.

INSTALLATION INSTRUCTIONS AND MAINTENANCE
1. Important notes
– The controls must be installed by qualified personnel
only. The relevant national regulations have to be
observed.
– On commissioning the wiring has to be carefully check-
ed according the appropriate diagram, Incorrect wiring
can damage the unit and endanger the installation.
– The fuse rating has to ensure that the limits specified in
TECHNICAL DATA will not be exceeded. If these precau-
tions are not observed, the effect of a short circuit can
cause severe damage to the control and installation.
– For safety reasons a minimum of one control shutdown
every 24 hours has to be observed.
– Disconnect the mains before the control box is plugged
in or out.
– The control box is a safety device and must not be
opened!
2. Function control
For safety reasons the flame detection system should be
tested on commissioning the installation as well as after a
service or longer shut-down.
a) Attempt to start with gas valve closed:
– At the end of the safety interval
-> Lockout
b) After a normal start, with the burner in operation, close
the gas valve:
– After restart at the end of the safety interval
-> Lockout
DKG 972
3. Fault finding
The built-in information system facilitate the trouble shooting
in the case of problems occurring during start-up or during
operation.
A list of possible lock out messages can be found in
APPLICATION FEATURES chapter 1.2.
Please note:
The control box is locked in lock out mode
and the reasen for the lock out is displayed
until the control box is reset, either by an
internal or external reset (see also subject “3.
Lock out and reset").
Removing the control box from its wiring base or by
interrupting the supply line may not reset a lock out. Therefore,
by applying power, it needs 2-3 secs. before the control box
goes to lock out again and the cause of the last lock out.
Error Possible fault
Burner not working - Thermostat circuit open
- Faulty electrical wiring
- Mains voltage < 187 V (< 80 V)
- Terminal A continuously on
   power (e.g. terminal A is used as
   a support terminal)
After 2-3 secs. after applying - Control box has not been reseted
power. the unit goes to
lock out
Burner starts, - stray light signal during waiting
flame not established, time
lock out - no ignition or no fuel
Burner starts, - no or too low flame signal (min.
flame established, valves see TECHNICAL DATA)
after safety time, - wrongly wired, phase and neutral
lock out reversed
- Ionisation probe dirty, broken or
has contact to frame ground
- too little light on flame sensIor
