      How the 'Under voltage' alarm works

      When the voltage of a cooler is below the Minimum Start Compressor Voltage, the SCS Controller can switch off the compressor to protect the asset and trigger an alarm to alert the site manager or staff.

      Review the fault logic for the "Under Voltage" alarm in the following graph:

      To check the present voltage for a cooler and any related alarms, or to update the parameters for 'Minimum Start Compressor Voltage' and 'Maximum Run / Start Compressor Voltage' connect to the SCS Controller with Field app.
