Abbey House 19-21 Fleet Street Pemberton Wigan WNS ODU England ISS.1.02/96 APPLICATION NOTES FOR FULL SEQUENCE CONTROL BOARD (OEM Copy) This document may be updated at any time without notificatioa It is therefore advised that a check is made to see if there is a later release copy.

1 Introduction 1.1 The FX30XXX1 is an electronic full sequence control (FSC) board designed for combustion appliances. 1.2 It is a dual fan speed controller allowing two air rates for the appliance under control. It incorporates, by design, features to allow many variations of the board as will be explained later under "Nomenclature". 1.3 It provides electronic ignition and flame detection by means of an ionisation probe which can also be configured as the spark electrode. Otherwise the spark and flame electrodes are kept separate. The control is also available with a volatile or...

2.3 IB2:- Air Pressure Switch terminal. 2.4 IB4:- Terminal for safely lockout device which is supplied with each board for panel mounting in the case of a non-volatile lockout board. This device carries with it an integral reset button. In the case of a volatile lockout control, this terminal is not present as it is replaced with an on-board volatile lockout device (a PTC thermistor). 2.5 IBS:- When a change-over to a different preset fan speed is required, 24 V d.c. is applied to pins 1 & 2 of this pin header for 2-speed RSF application. The fan is thus switched between high and low...

2.8 IBS:- Lockout indicator4. A neon indicator connected to this terminal will light up if a lockout has occurred, or if the lockout device is missing or faulty. The neon may flicker during ignition but will extinguish after flame detection. 2.9 TAG1:- Flame detection electrode. Not required for a single probe arrangement If flame is not established within a specified safety time, the board proceeds into lockout 2.10 TAG2:- ignition electrode, hot end. In the case of a single probe control, this terminal also detects the flame. 2.11 TAG3:- Ignition electrode, earth end. Not required for...

3.1.2 2nd Letter:- Lockout mode/Safety time. L - Non-volatile lockout with 5 seconds safety time. M - Non-volatile lockout with 10 seconds safety time. N - Non-volatile lockout with 15 seconds safety time. V - Volatile lockout with 10 seconds safety time. W - Volatile lockout with 15 seconds safety time. 3.1.3 3rd Letter:- Probe(s) arrangement D - Dual probe. 3.2 It therefore follows that at least 32 versions of the FX30xxx configurations are possible. Not all of these are viable commercially and it will be expected that the actual number of variants will be much less. There...

4 Classification. 4.1 The classification of this control is:- FMRLXK or FMRVXK depending on variant Please refer to nomenclature on page 5. Supply Voltage Tolerance +10, -15 % 5.2 Power Consumption:- (Excluding all peripherals) Maximum Peak 75 VA 5.5 ignition:-Maximum Spark Frequency 50 Sparks/Sec. Minimum Spark Frequency No limit Where there have been design revisions, please note that the specification refers to that of the existing current issue of the design which may be different from the original specification.

Spark Energy (gross) 20 mj Maximum Length of Lead 1.5 m Type of Lead EHT Multi-strand with break down voltage of at 5.6 Spark Gap:-Recommended Setting 3 +1,-0 mm Maximum Minimum 5.8 Flame:-Type of detection Ionisation. Flame Current Sensitivity:- 2.0 pA Nominal Probe Voltage 230 V a.c (No condensation) Enclosure:- Depends on application but a minimum of IP40 is recommended. The enclosure must be of one of the following:-I) All-metal construction with earthing provision to the main frame of the appliance, ii) Totally non-conductive construction with no...

Board Mounting:- Any attitude but not upside down. 5.10 Exclusions To Use. 5.10.1 The FX30xxx is currently not phase sensitive but the FX30SFT is. It is therefore not suitable for applications where phase-sensitivity is necessary for safety requirements. In such cases, however, provided double insulation wiring (cable with an overall sheath) is used for connection between a) The FX30 and the safety gas valve b) The overheat protection device it will be possible for the FX30 to be used. 5.10.2 This control is not meant for inter-building controls application.

TCfflTCf CONTROLS_ Flame Probe Connection to the FX30SPT is via the special 10-way connector obtianable from Abbey Electronics. The board should be wired as shown above for Permanent Pilot application. The flame should be sensed on the pilot For direct burner ignition (DBI) use GV1 as the burner. For dual probe (separate spark/flame sensing) operation connect SR to earth. For single probe (combined spark/flame sensing) connect SR to FP. The spark electrode will thus sense flame as well. The OEM should observe all the normal rules and regulations governing electrical wiring and safety. MRTL...
