Oil burner controls  For oil atomizing burners of medium to large capacity  For multistage or modulating burners in intermittent operation  With or without air pressure supervision for checked air damper control  Flame supervision – with photoresistive detector QRB – or blue-flame detector QRC1 – or silicon photocell detector RAR9  Suitable for use with air heaters (WLE) The LAL and this Data Sheet are intended for OEMs which integrate the oil burner controls in their products! Use  For the control and supervision of oil atomization burners  For burners of medium to high capacity  For intermittent operation (at least one controlled shutdown every 24 hours)  Can be universally used with multistage or modulating burners  Suited for use with stationary air heaters (WLE) The flame supervision is ensured via a Photoresistive detectors QRB，blue-flame detectors QRC1 or Silicon photocell detectors RAR9.

Do not 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, completely isolate the plant from mains supply (all-polar disconnection). Ensure that the plant cannot be inadvertently switched on again and that it is indeed dead. If not observed, there is a risk of electric shock hazard  Ensure protection against electric shock hazard by providing adequate protection for the burner control’s connection terminals  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»  Press the lockout reset button only manually (applying a force of no more than 10 N), without using any tools or pointed objects  Do not press the lockout reset button on the unit or the remote reset button (input 21) for more than 10 seconds since this will damage the lockout relay in the unit  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  For safety reasons – self-test of the flame supervision circuit, etc. – at least one controlled shutdown must take place every 24 hours Mounting notes  Ensure that the relevant safety regulations are complied with  Connect the earthing lug inside the terminal base to burner ground using a screw with a lockwasher  Note! In applications involving air heaters (WLE), or in the case of oil burners with a maximum throughput of >30 kW/h, removing wire link B is not permitted. Installation notes  Always run high-voltage ignition cables separately, with the greatest possible distance to the unit and to other cables  Live and neutral conductors must not be mixed up  Install switches, fuses, earthing, etc., in compliance with local regulations  Make certain that the maximum permissible current rating of the connection terminals will not be exceeded  The insulation on internal wiring which is subjected to the mains voltage must withstand the electrical stress occurring during correct use 3/24 Building Technologies Division CC1N7153en 21.09.2016 Electrical connection of the flame detector It is important to achieve practically disturbance- and loss-free signal transmission:  Never run the detector cable together with other cables – Line capacitance reduces the magnitude of the flame signal – Use a separate cable  Observe the permissible cable lengths (refer to «Technical data») Commissioning notes When commissioning the plant or when doing maintenance work, make the following safety checks: Safety check to be carried out Anticipated response a) Burner startup with flame detector darkened Lockout at the end of safety time (TSA) b) Burner startup with flame detector exposed to extraneous light Lockout after 40 seconds at the latest c) With wire strap «B»: Simulation of loss of flame during operation. For that purpose, darken the flame detector during operation and maintain that state Lockout d) Without wire strap «B»: Simulation of loss of flame during operation. For that purpose, darken the flame detector during operation and maintain that state Repetition followed by lockout at the end of «TSA» e) Burner startup with response of air pressure switch Prevention of startup/lockout during prepurge time f) Burner operation with simulated air pressure failure Immediate lockout Engineering notes  Install switches, fuses, earthing, etc., in compliance with local regulations  Connect valves and other plant components as specified in the burner manufacturer’s documentation H N L EK2 AL 21 1 2 1(3) 3 R 4 5 6 7 BV2 BV1 Z SA 15 16 17 18 a z 20 19 9 LR 7153a03/0814 24 m LK 11 10 8 22 B v LP 14 12 13 23 LAL2 1 2 3 4 5 6 7 8 9 10 QRB... 22 24 + RAR...
