Grundfos CU 362 User Manual

• The red indicator light on the operating panel lights up (only in
case of alarm).
• "Current alarms" appears as the first line below the pit graphics.
• The alarm relay operates.
• The indication is maintained as long as the system has an active
alarm. An alarm is active until it has been reset, either
automatically or manually via "Current alarms" in the status
display.
• An alarm cannot be reset until the fault causing the alarm has
been corrected. Example: An overtemperature alarm cannot be
reset until the pump has cooled.
Float switches and mixer only appear if they are installed
in the system.
