DESCRIPTION

Valves

The Combined Valve and Ignition (CVI) system controls and performs all the functions required for safe ignition, flame supervision and for safely regulating the gas flow to the pilot and/or main burner.

The CVI consists of a gas valve of the VK41.. series and a dedicated ignition control of the series S4565, S4575 and

S4585 which is connected directly on to it.

Ignition control

The S4565, S4575 or S4585 220/240 Vac series ignition controls can be directly electrically connected to a VK41.. series gas control.

The S4565/S4575 ignition controls are not intended for direct exposure to flame envelope.

S4565, S4575 and S4585 ignition controls give excellent performance and a high reliability standard. There are versions available for different ignition systems:

The S4565/S4575 ignition controls are approved on the

North American standard ANSI Z21.20 Automatic Ignition

Systems.

S4565, S4575 and S4585 systems function in accordance with EN 298.

SYSTEM OPERATION

General

Lock-out reset

The S4565A, B, P and Q ignition controls can be reset by either depressing the internal/external reset button (suffix A and B) or by interrupting the permanent live connection

(suffix P and Q).

If a first reset is not succesful, wait at least 15 seconds before attempting another one.

NOTE 1.: When first starting, the ignition control can be in the lock-out condition; depress the reset button to free the ignition control. After a manual reset an extended prepurge/waiting time will occur.

NOTE 2.: If during normal use the reset button is pressed, the gas valves drop out and the ignition control starts a new sequence after releasing the reset button.

NOTE 3.: If permanent alarm output: neon indicator with integral resistor >150 kΩ (max 1 mA)

NOTE 4.: If an automatic return high limit thermostat is used, the high limit switch in the application needs a longer return time than the trial for ignition time of the ignition control. This in order to provide non volatile lock out.

S4565A, B, P, Q

Suffix A, B, P and Q (see Fig. 7.)

When there is a call for heat a self check period (Tc) plus waiting period (T w

) elapse before built-in igniter and gas valve are switched on.

The ignition spark ignites gas and resulting flame is detected by the flame rod.

Ignition is switched off after extended ignition time and flame establishment.

If flame is not established within the safety time (T s

), the ignition control locks out.

If the flame is lost during normal run, the ignition control repeats the start sequence.

SYSTEM OPERATION S4565AD, BD, CD, DD, PD, QD, RD, SD, TD “2000” SERIES

General

The S4565AD, BD, CD, DD, PD, QD, RD, TD ignition controls can provide both closed-loop sparking and sparking to ground.

The S4565SD ignition circuit and rectifier provides closedloop sparking.

Lock-out reset

The ignition control can be reset by either depressing the internal/external reset button (suffix AD, BD, CD and DD) or by interrupting the permanent life (suffix PD, QD, RD and

TD).

NOTE 11.: When first starting, the ignition control can be in the lock-out condition, depress the reset button to free the ignition control. After a reset an extended waiting time will occur.


NOTE 13.: If permanent alarm output:neon indicator with integral resistor >150 kΩ (max 1 mA).

Do not connect any electrical load to the heat demand input, it will influence proper functionality.

) the status signal must be logic “0”.

• After the waiting time (T w signal must be logic “1”.

) and without flame the status

• After flame detection the status signal must be “50 Hz”.

• If after the safety time (T s

) there is no flame detection, the ignition control goes to volatile lock-out. The status signal is logic “0”.

• If high limit (LM) opens during operation the status signal becomes logic “0”. The ignition control makes a restart but the status signal stays logic “0” during the safety time (T s

).

This is the high limit indication status. The ignition control goes to volatile lock-out. The comfort boiler control has to store this status in a semi permanent memory in order to achieve non volatile lock-out. Line voltage interruptions may not cause data loss.

General

The S4565PV, QV, RV, TV ignition controls can provide closed-loop sparking, sparking to ground or combined sparking and flame sensing.

Lock-out reset

The S4565PV, QV, RV, TV ignition controls can be reset by interrupting the permanent live or by pressing the reset button for at least 1 s.

The S4565RV, TV versions with prepurge can be reset by interrupting the heat demand for at least 1 s.

The application of this type of control is therefore restricted to those applications where resetting by switching off the heat demand is allowed by European appliance standards. Reset of an appliance in lock-out must occur by means of a conscious manual action and not by means of automatic devices like thermostats or timers.

STATUS OUTPUT APPLICATION

The lock-out status data from the S4565PV, QV, RV, TV ignition controls can be read by the microprocessor in the comfort boiler control and stored in its EEPROM.

The relay contact is controlled by the microprocessor and activates the S4565PV, QV, RV, TV.

During the start sequence the status output gives status information of the S4565PV, QV, RV, TV.

The status information can be found under chapter

SPECIFICATIONS paragraph:“Opto coupler status output” on page 41

If the signal of the status output does not correspond to the specifications, the comfort boiler control can shut off the ignition control.

Atmospheric ignition control S4585D (see Fig. 73.)

After false flame check during self check time (T c

) a built-in igniter and pilot gas valve are switched on.

The ignition spark ignites gas and resulting flame is detected by the combined flame/ignition rod.

Ignition is switched off immediately after flame is established and main gas valve is then energized.

If the flame is lost during normal run, the main gas valve is de-energized and re-ignition of pilot occurs.

S4585D

Fan assisted ignition control S4585D (see Fig. 73.)

When there is a call for heat, fan is energized through no air position of air proving switch after self check time (T c

).

When sufficient air flow is proven by air proving switch, a built-in igniter and pilot gas valve are swiched on.

The ignition spark ignites gas and resulting flame is detected by the combined flame/ignition rod.

Ignition is switched off immediately after flame is established and main gas valve is then energized.

If air flow is not proven by air proving switch automatic ignition controller will remain in a waiting mode with fan energized.

If the flame is lost during normal run, the main gas valve is de-energized and re-ignition of pilot occurs.

No flame indication

If no flame indication is built in, the indicator ligths up if there is no flame detection within the no flame indication period

GENERAL CONSIDERATIONS

To ensure reliable long term operation, mount ignition control at a position in the appliance with a low ambient temperature and a low radiation.

The ignition control should be externally fused.

High temperatures will affect product life.

After installation wait at least 1 hour before connecting to mains.

NOTE 22.: Electrical rating of connected controls and air proving switch should be appropriate for the load that is switched by the ignition control.

NOTE 23.: Power interruptions will cause program restart.

NOTE 24.: The flame connection pin of all types is protected against electrical schock. The gas pressure switch as mentioned in this instruction sheet is a functional device.

NOTE 25.: If the ignition control incorporates an EMC filter, disconnect the ignition controller from mains before performing a dielectric strength test.

WARNING

Honeywell is not responsible for damage, injury due to mis wiring.

After installation the ignition control can become wet due to condensation.

Do not connect wet device to mains

59 EN2R-9031 0211R14-NE

EMC GUIDELINES

The ignition cable has to be determined for lowest emission.

Do not lead ignition cable close to other cabling.

To suppress Radio Frequency Interference (RFI) the ignition control including spark igniter cabling should be mounted in sufficient shielded environment.

EN2R-9031 0211R14-NE 60

ELECTRICAL CONNECTIONS AND WIRING

IMPORTANT

Take care that installer is a trained experienced service person.

Disconnect power supply to prevent electrical shock and/or equipment damage.

Turn off gas supply before starting installation.

Wiring must be in accordance with local regulations.

The appliance manufacturer’s instructions should always be followed.

Before installing or replacing any control check that type number is correct for the application.

Ensure combustion chamber is free of gas before start up.

Conduct a thorough check out when installation is completed.

At the first start the ignition controller can be in lock out; depress reset button to free control.

CAUTION

Do not connect the ignition control to power supply when it is not connected to the gas control.

Wiring

• Use cable which can withstand 105°C ambient.

• Use cable which is proven against moisture.

• Wiring between ignition control and spark sensing probe should have good quality insulation, suitable for the temperatures encountered.

If ignition frequency q 25 Hz or pulse energy

> 45 µAs the ignition cable and its connections shall have a protection against electrical shock hazard.

For single rod applications, the ignition/sensing cable and its connections shall have protection against electrical shock hazard.

Label all wires prior to disconnection when servicing ignition controls. Wiring errors can cause improper and dangerous operation.

If electronics components are installed in an area subject to water (dripping, spraying, rain etc.), means shall be provided to protect these components.

Flame relay output is not accessible when the normally closed output is present.

Fusing

In order to prevent unsafe conditions at too high current, the ignition controls have an integral non replaceable fuse.

This fuse will be blown long before the maximum 16 A external fuse switches off.

Spark gap

Max. allowable spark gap 3.5 mm

Supply voltage polarity

WARNING

If ignition control (without the phase neutral

independent operation feature) seems to operate normally but does not detect flame, check for right polarity of power supply (line, neutral).

Checking flame current

• The minimum value should be in accordance with specified value.

• To check flame current connect a dc micro-Ampèremeter between flame sensing wire and flame sensing rod.

• Meter connections polluted with e.g. alkaline substances lying close to earth can cause flame current simulation.

Make sure no false flame current can flow from meter connections to earth.

• If flame current is insufficient check that the flame sensing rod is fully enveloped by the flame and that burner and ignition control are reliable grounded.

• If there is no sufficient flame current due to phase-phase mains it is recommended to use an ignition control with the phase neutral independent operation feature. If this is not available, it is recommended to use a AT7030A or

AT7030B flame detection transformer. See also instruction sheet EN1R-9136 for the AT7030 transformer.

Flame sensing wiring

The S4565/S4575 and S4585 ignition controls are equiped with flame sensing by ionisation current based on the flame rectification principle.

Via a high ohmic source a high voltage is applied to the flame rod.

Because of the high impedance the flame rod connection is safely accesible according to EN 60730.

Since the flame sensing input is very sensitive and the current detection threshold is only a few tenths of microamp, care must be taken that no spurious current flows.

The flame rod wire must have creepage to earth of at least 10 mm.

Contacts of the flame rod wire must not be imposed to fluids or dirt.

WARNING

Short µA meter during ignition, to prevent damage of the µA meter in single rod application.
