Здравствуйте!
Добрался до котла.
Повесил вместо датчика пламени резистор на 1.3Ком начал вываливаться сразу в аварию LME горит красным.
Между выводами уф датчика бесконечное сопротивление, попробовал колхозный метод по проверки датчика, зажигаешь зажигалку рядом с лампой и должно появится свечение. Свечения нет. Не знаю даже, рабочий способ или нет.
Еще способ, визуальный, если на электродах имеется фиолетовый налет, значит датчик вышел из строя. Налет действительно есть.
По паспорту для проверки нужен микроамперметр, подойдет ли для этого цифровой мультиметр китайский?
Электролиты есть, а какое-то напряжение нужно подавать на уф-датчик? Или просто замкнуть цепь микроамперметром и параллельно к амперметру подключить конденсатор? И что использовать для засветки датчика?

Допустим датчик не годный, можно ли какой-то более дешевый аналог подобрать, цена на эту стекляшку 32К.
По паспорту наработка датчика 10 000 часов, котлу уже 10 лет))).

Warning notes

Engineering notes

Mounting notes

To avoid injury to persons, damage to property or the environment, the following warning notes should be observed!

Do not to open, interfere with or modify the unit!

• All activities (mounting, installation and service work, etc.) must be performed by qualified staff

• Before making any wiring changes in the connection area of the LME…, completely isolate the burner control from the mains supply (all-polar disconnection)

• Ensure protection against electric shock hazard by providing adequate protection for the burner control’s connection terminals

• Check the connecting lines of the air pressure switch for short-circuits (connection terminals 3, 6 and 11)

• Press the lockout reset button / operation button only manually (applying a force of no more than 10 N) without using any tools or pointed objects

• Fall or shock can adversely affect the safety functions. Such units must not be put into operation, even if they do not exhibit any damage

• Each time work has been carried out (mounting, installation, service work, etc.), check to ensure that wiring is in an orderly state and make the safety checks as described in «Commissioning notes»

• When used in connection with actuators, there is no position feedback signal from the actuator to the burner control

• When used in connection with actuators, the requirements of EN 676 must be observed

• The running times of the actuators must match the burner control’s program. An additional safety check of the burner control together with the actuators is required

• When substituting burner controls type LGB… or LMG… by LME…, the AGQ1… or

AGQ2… ancillary unit must be replaced by the AGQ3…

• Ensure that the relevant national safety regulations are complied with

Installation notes

• Always run the ignition cables separate from the unit and other cables while observing the greatest possible distance

• Do not mix up live and neutral conductors

• Install switches, fuses, earthing, etc., in compliance with local regulations

• The connection diagrams show the burner controls with earthed neutral conductor.

In networks with nonearthed neutral conductor and ionization current supervision, terminal 2 must be connected to the earth conductor via an RC unit (type reference

ARC 4 668 9066 0). It must be made certain that local regulations are complied with (e.g. protection against electric shock hazard) since AC 230 V / 50 Hz mains voltage produces peak leakage currents of 2.7 mA

• Make certain that the maximum permissible current rating of the connection terminals will not be exceeded

• Do not feed external mains voltage to the control outputs of the unit. When testing the devices controlled by the burner control (fuel valves, etc.), the LME… must not be connected

• In the case of burners with no fan motor, an AGK25 must be connected to terminal

3 of the unit, or else the burner cannot reliably be started up

• For safety reasons, feed the neutral conductor to terminal 2. Connect the burner components (fan, ignition transformer and gas valves) to the neutral distributor as shown below in figure 7101a05. The connection between neutral conductor and terminal 2 is prewired in the base

Wiring of neutral conductors!

Electrical connection of flame detectors

It is important to achieve practically disturbance- and loss-free signal transmission:

• Never run detector cables together with other cables

– Line capacitance reduces the magnitude of the flame signal

– Use a separate cable

• Observe the permissible length of the detector cables (refer to «Technical data»)

• The ionization probe is not protected against electric shock hazard

• Locate the high-voltage ignition electrode and the ionization probe such that the ignition spark cannot arc over to the ionization probe (risk of electrical overloads) and that it cannot adversely affect the supervision of ionization

– Must be a minimum of 50 M

Ω between ionization probe and ground

– Soiled detector holders reduce the insulation resistance, thus supporting cree-

page currents

• Earth the burner in compliance with the relevant regulations; earthing the boiler alone does not suffice

Resetting the burner control

Limitation of repetitions

(only LME11…)

• Burner control must be reset

• All contacts in the line are closed, request for heat

• Air pressure switch «LP» must be in its no-load position or CPI or wire link 2

• Fan motor or AGK25 is closed

• Flame detector is darkened and there is no extraneous light

• Safety shutdown from the operating position takes place should mains voltage drop below about AC 175 V (at U

N

= AC 230 V)

• Restart is initiated when mains voltage exceeds about AC 185 V (at U

N

= AC 230 V)

After no more than 24 hours of continuous operation, the burner control will initiate automatic controlled shutdown followed by a restart.

If the connections of live conductor (terminal 12) and neutral conductor (terminal 2) are mixed up, the burner control will initiate lockout at the end of «TSA».

If lockout occurs, the outputs for the fuel valves, the burner motor and the ignition equipment will immediately be deactivated (< 1 second).

In the event of lockout, the LME… remains locked and the red signal lamp (LED) will light up. The burner control can immediately be reset. This state is also maintained in the case of mains failure.

When lockout occurs, the burner control can immediately be reset. To do this, press the lockout reset button for about 1 second (< 3 seconds). The LME… can only be reset when all contacts in the line are closed and when there is no undervoltage.

If no flame is established at the end of «TSA», or if the flame is lost during operation, a maximum of 3 repetitions per controlled startup can be performed via «R», or else lockout will be initiated. Counting of repetitions is restarted each time a controlled startup via «R» takes place.

The multicolor signal lamp (LED) in the lockout reset button is the key indicating element for visual diagnostics and interface diagnostics.

LED

Both «EK…» and LED are located under the transparent cover of the lockout reset button.

There are 2 diagnostics choices:

1. Visual diagnostics: Operational status indication or diagnostics of the cause of fault

2. Interface diagnostics: With the help of the OCI400 interface adapter and the

ACS400 PC software or flue gas analyzers of different makes (refer to Data Sheet

N7614)

Visual diagnostics:

In normal operation, the different operating states are indicated in the form of color codes according to the color code table given below. Interface diagnostics is activated by pressing the lockout reset button for at least 3 seconds (refer to Data Sheet N7614).

If, by accident, interface diagnostics has been activated, in which case the slightly red light of the signal lamp flickers, it can be deactivated by pressing again the lockout reset button for at least 3 seconds. The instant of switching over is indicated by a yellow light pulse.
