CONTROLLERS TYPES G.. OR.. Series 03N AUTOMATIC CONTROL SYSTEMS FOR OIL BURNERS APPLICATION The electro-mechanical controllers of this series are designed to control oil burners in non-permanent applications. These controllers are suitable for : − monoblock burners − power washers − hot air generators − steam boilers − furnaces Due to the models technical and constructive features and to their variety they can be used also for the automation of cookers, and of plants employing oil burners generally, whether in domestic or industrial applications. These controllers replace integrally the 03 electro-mechanical series FEATURES Table 1 shows the main features of this series. Other important features are: − two independent safety contacts for valve driving − electrical service life at max. declared load > 250.000 operations; − Easy installation and connection.

Both bases are provided with screw terminals which Upon request: 110V 50/60Hz allow a safe and easy connection. It’s advisable to use M4 24V dc and ac 50/60Hz screw for fastening purpose. 12V dc and ac 50/60Hz Operating temperature -10°C ÷ +60°C Protection degree (with base) IP 40 Times – Pre-purge time (TV @ 20°C): 15/20 s – Safety time (TS @ 20°C): 5/10 s – Response time in case of flame failure: <1s Power consumption (@220V-50Hz): 6,5 VA (@12V/24V ): 1VA Internal Fuse – For 220V e 110V supply voltage: 6,3 A time-delay – For 24V e 12V supply voltage: 10 A time-delay External fuse – For 220V e 110V supply voltage: 4 A fast-blow – For 24V e 12V supply voltage: 10 A fast-blow Weight including connection base: about 240 g Max. contacts rating (@220V): Imax Fig.2 – Thermostat: 6,0 A cosϕ > 0,4 – Motor: 2,0 A cosϕ > 0,4 ACCESSORIES – Ignition transformer: 2,0 A cosϕ > 0,4 The following indications must be considered in order to – EV1: 0,5 A cosϕ > 0,4 choose the suitable flame detector for the controller and the application type: – EV2: 0,5 A cosϕ > 0,4 – Preheater: 0,5 A cosϕ = 1,0 Controller Type Photocell – Lockout signal: 1,0 A cosϕ = 1,0 - G22, GF2, GF3 Max. contacts rating (@12V e 24V): Imax FC8/R 1,5..5,5 lux – Thermostat: 10 A cosϕ > 0,4 Frontal side FC8/A 1,5..3,0 lux – Motor: 4,0 A cosϕ > 0,4 FC8/V 5,5.. 10 lux – Ignition transformer: 3,0 A cosϕ > 0,4 – EV1: 1,5 A cosϕ > 0,4 FC7/R 1,5..5,5 lux – EV2: 1,5 A cosϕ > 0,4 Lateral side FC7/A 1,5..3,0 lux – Lockout signal: 1,0 A cosϕ = 1,0 FC7/V 5,5…10 lux - OR1, OR2, OR3 CONSTRUCTION Frontal and lateral side FC11/R* 1,5..6,5 lux The plastic enclosure protects the controller against mechanical damage caused by crash, tempering , dust and Frontal and lateral side FC13/R 1,5..6,5 lux dirt of external ambient.
