The safety function is a feature of the actuators, which is mandatory by law or customer requirement, to close or open the valve in case of a power failure. endobj . 1426 0 obj If the motor is forced to draw too much current (in this case probably by excessive mechanical resistance in the valve mechanism) then the windings will overheat and are likely to eventually develop an open circuit failure. All the AME actuators have the possibility to choose either voltage input signal from the controller (U) or current signal from the controller (I) on a DIP switch. My Boiler Wont Switch Off Danfoss Motorized Valve When the central heating system is switched on the danfoss motorised heating valve is opening the central heating water valve to allow the radiators to heat up, however when the central heating system switches off the danfoss motorised valve will shut off the water valve and stop circulation to the radiators as it should do but fails to send the signal to the boiler to shut down into standby mode, subsequently, the boiler and central heating water pump continue to run while not heating the radiators or hot water.Fitting a new danfoss motorised valve solved the problem.https://www.amazon.co.uk/Danfoss-HPA2-Actuator-4-Wire/dp/B003QZKN26/ref=pd_sbs_60_1?_encoding=UTF8\u0026pd_rd_i=B003QZKN26\u0026pd_rd_r=42ac493d-0c1e-11e9-9334-2994f224cbbe\u0026pd_rd_w=h0x4s\u0026pd_rd_wg=1lkQw\u0026pf_rd_p=18edf98b-139a-41ee-bb40-d725dd59d1d3\u0026pf_rd_r=3QB3CCSPH0R6KCBK5DMQ\u0026psc=1\u0026refRID=3QB3CCSPH0R6KCBK5DMQ I have right or not?)
