i-on Range Installer Menu OptionsPage 129System Voltage This option displays the dc voltage present on the expanderPCB just after the mains transformer and principal voltageregulator. If it shows anything other than 13.6V then thisindicates that there may be either a mains “brown out” or thatthe expander is running on its standby battery.Aux 1 Voltage This option shows the voltage on the 12V line of the Aux 1terminals.Aux 2 Voltage This option shows the voltage on the 12V line of the Aux 2terminals.Comms O/P voltage This option shows the voltage on the 12V positive terminal ofthe plug-by communications connector.Bus Voltage This option shows the voltage on the 12V line of the system busgoing out of the expander.Load Current This shows the total current drawn by Aux 1, Aux 2, CommsO/P 12V supply, and the bus out 12V supply.Mains Condition This option shows the condition of the mains power at theexpander. It shows “Healthy” when mains is present or “Missing”when mains is absent.Battery 1 Status This option shows the condition of battery 1. “Health” meansbattery present, in good condition and charged. “Low” meanbattery present but discharged. “Missing” means battery is notconnected.Battery 2 Status160This option will be present if you have an EXP-PSU connectedto the system and have enabled its battery 2 inDetectors/Devices – Wired Expanders - Edit Expanders– (seepage 55).
