EBL512 G3 V. 3.0.X - FIRE ALARM SOLUTIONS OPERATING INSTRUCTIONS107If you get “No reply from control unit.....” the control unit don't exist or don't answer.31.4. DISPLAY CURRENT CONSUMPTION IN UNIT (H5/A4)POWER SUPPLY (CONTROL UNIT)Voltage: The 24V measured by the CPU on the main board. Corresponds to the output voltage at the power supply outputs onconnector J3.Earth voltage: Measured from 0V (connector J4:2) to earth.Current from power supply: The total current consumption (including the charging current at 24V) for the selected control unit(c.i.e.) when it is connected to the mains (230 V AC), i.e. this function is not working by battery backup.BATTERYVoltage: The battery voltage at connector J4:4-5.Charging current: The battery charging current for the selected control unit (c.i.e.).Temperature: The temperature detected by the battery temperature sensor.Resistance in battery circuit: During the battery capacity check the resistance in the battery circuit is measured. A resistance >500 mΩ will result in a "Low battery capacity" fault. Checked every 15 minutes.a) Log on to the c.i.e.b) Navigate to menu A4.c) Write control unit number and press .d) Please wait.e) To exit the menu press or ESC.The information is automatically updated every 5th second.Power supply (control unit xx)Voltage: xx.xx VEarth voltage: xx.xx VCurrent from power supply: xxx mABatteryVoltage: xx.xx VCharging current: x mATemperature xx°CResistance in battery circuit: xxxxx mΩ
