Alarm settings
WM20 manages two alarms. The following is defined for each alarm:
• variable to be controlled (Variables), selectable from all measured electrical variables
excluding the maximum power values
• alarm activation threshold (Set1)
• alarm activation delay (On delay)
• alarm deactivation threshold (Set 2)
To set the alarms, see "Settings menu" on page 24, to check the status of set alarms,
see "Information menu" on page 31.
Up alarm (Set 1 > Set 2)
If Set 1 > Set 2, the alarm is activated when the controlled variable exceeds the value of
Set 1 for a time equal to On delay and is deactivated when it falls below Set 2.
