IndicatorsThe diagnostic indicators visible along the edge of the power supply indicate the status of the unit as follows:AC Normal – Mains power is connected.Heartbeat (flashing slowly) – The processor is functioning normally.DC Out on – The 24V DC output is supplying power to the load.General fault – The battery charge voltage is too highEarth fault – The 24V DC supply is connected to earth.Battery low – The battery voltage is below 21 Volts.Battery disconnected – The battery is disconnected or the charging circuit hasreached higher impedance than it should.7. CommissioningOnce all connections have been made and checked for safety, ensure that batteries are correctly connected and switchon the mains power.Check that the AC Normal LED is on.Check that the Heartbeat LED is flashing slowly.Check that power is being supplied to the load with a volt meter. A voltage of 24V +/- 1V should be read.Remove the mains power and ensure that the batteries continue to supply power to the load.With the mains removed, the AC Normal indicator should switch off after approximately 30 seconds.Switch the mains back on and disconnect the battery. The load should continue to operate and the Batterydisconnected LED should light.This completes the basic commissioning checks.Q4C19C93RV1L17R109T2GNDOUT ONDCBEATDISCONBATHRTBATFLTLOWACFLTNORMGEN+slot slotslotAC NormalHeartbeatGeneral faultDC Out onEarth faultBattery lowBattery disconnected |
