For systems used in the open air, the protection shall conform to at least IP 54 when installed in accordance with the installation and operating instructions. For systems without enclosure, equivalent protection shall be provided by the appliance in which it is installed. 6.5.3 Electrical components Shall be according to EN 13611:2007+A2:2011, 6.5.3. 6.6 Protection against internal faults for the purpose of functional safety 6.6.1 Design and construction requirements 6.6.1.1 Fault avoidance and fault tolerance Shall be according to EN 13611:2007+A2:2011, 6.6.1.1. 6.6.1.2 Reset device Shall be according to EN 13611:2007+A2:2011, 6.6.1.2 with the following modification: SIST EN 1643:2014

The VPS shall prevent the opening of the valve and operation of the ignition system when the detection limit is exceeded. Interruption of the mains supply and its restoration shall not affect the safety of the programme sequence. If mains interruption and its restoration result in automatic recycling and overriding of any interlock, the VPS shall restart from the beginning of the programme sequence. 7.101.2 Programme sequence The programme sequence for the VPS shall enable ignition and opening of the valves to operate the burner below the detection limit, and shall prevent ignition and opening of the valves when the detection limit is exceeded, in accordance with 7.101.5, followed by a lock-out. The lock-out may be executed on the system application direct or by the VPS itself. An automatic start-up attempt by a control function shall not override the lock-out conditions. Any gas necessary for the operation of the VPS may be discharged into the combustion chamber during the programme sequence if the maximum release volume, expressed in litres per switching sequence, does not exceed 0,083 % of the burner heat input referred to the nominal volume flow, expressed in cubic metres per hour. NOTE 0,083 % is based on the quantity within 3 s. However, when the VPS is used as an alternative for pre-purge or post-purge, discharge of the gas necessary for the operation of the VPS into the combustion chamber might not be allowed; the gas shall be vented into the atmosphere at a safe location. If the actuating energy in the safety circuit fails, the VPS shall close the main gas valves and any ignition gas valve or give a shut-down signal to the automatic gas-burner control system. 7.101.3 Timing The leakage testing time and the pressure pump time (if applicable) shall be specified in the installation and operating instructions. Adjustment of safety critical timing is permitted but shall be possible only by means of tools. Where these times can be adjusted using an existing scale on the component, the scale shall be accurate to ± 10 % of the indicated value. The means of adjustment shall be readily identifiable (e.g. colour-coded). SIST EN 1643:2014
