TERFERENCE ON THE BYPASS LINE An alarm condition exists when there is interference on the bypass line such as voltage peaks or harmonic distortion while the voltage and frequency are correct WARNING in this case the inverter is not synchronized with the bypass line so if the bypass is forced using the SWMB switch from remote controls or from the panel incorrect switching between voltages may occur in phase opposition 2 MANUAL BYPASS SWMB ON or CABLE FAULT The SWMB manual bypass switch is inserted and prevents the return to normal mode The load is powered by the bypass line input and is therefore not protected by the UPS CABLE FAULT only for UPS units in parallel configuration the logic has detected an error in the signals exchanged between the UPS connected in parallel and has therefore switched the whole system to bypass 3 BYPASS VOLTAGE ERROR or SWIN OFF The alarm exists if the input voltage of the bypass line is incorrect the SWIN input switch is open 4 POWER VOLTAGE ERROR or SWIN OFF The power supply voltage is incorrect and so the battery is discharging An alarm condition exists if one of the following events occurs the power voltage or frequencies of the rectifier power supply line are in an acceptable range see General Characteristics the SWIN input switch is open the rectifier does not recognise the voltage due to an internal fault 5 PREALARM LOW VOLTAGE ON BATTERY An alarm exit
