Description
The submenu in the display Alarm shows the following:
• Warnings caused by faults that still exist.
• Warnings caused by faults that have disappeared, but the
warning requires manual resetting.
• Alarms caused by faults that still exist.
• Alarms caused by faults that have disappeared, but the alarm
requires manual resetting.
All warnings and alarms with automatic resetting are automatically
removed from the menu when the fault has disappeared.
Alarms requiring manual resetting can be reset in this display
by pressing [OK]. An alarm cannot be reset until the fault has
disappeared.
For every warning or alarm, the following is shown:
• Whether it is a warning or an alarm
• Where the fault occurred: System, Pump 1, Pump 2, etc.
• In case of input-related faults, the input is shown.
• The cause of the fault and the alarm code in brackets, such as
"Water shortage (214)".
• When the fault occurred: Date and time.
• When the fault disappeared: Date and time. If the fault still
exists, date and time are shown as "--...--".
The most recent warning or alarm is shown at the top of the display.
