Alarms are categorized as A- or B-alarms to differentiate between different priority levels
with A-alarms being more serious than B-alarms. The relay contacts can be configured to
output either A- or B-alarms.
Table 8: Pump and process alarm
Alarm Configurable Value Description
Pump leakage Yes A-Alarm Active when leakage is detected in the pump. Must only be
activated for pumps that are equipped with a leakage sensor.
High pump
temperature
No, fixed A-Alarm, stop
pump
Active when the pump motor is too warm due to over current.
Always stops the pump.
High sump level Yes A-Alarm Active when the level switch gives a signal due to high sump
level.
Level sensor error Yes A-Alarm Active when the level sensor malfunctions or for example:
• Reports a water level above the start level at the same
time as the pump snores
• Freezes the signal and stays at the same level below the
start level at the same time as the water reaches the high-
level switch
• Is not connected and the water level reaches the high-
level switch
• Is connected but not installed in the sump and the water
level reaches the high-level switch
As long as this alarm is active, the level sensor signal is ignored
and the drive operates using the level switch.
High sump level Yes A-Alarm Active when the level sensor reports a water level 12% above
the start level (0.6 m (1.97 ft) with 0–5 m (0–16.4 ft) sensor
range).
The process alarms Pump leakage, High sump level (level switch), Level sensor error, and
the High sump level (level sensor) are configured in the P1-21:Sensor max level,
P1-22:Leakage alarm setup, P1-23:Hi lvl alarm setup-Dig, and P1-24:Hi lvl alarm set. -

Alarm log
If an alarm is reset or triggered, then it is registered with an alarm code, time stamp, and
information in the alarm log. The time stamp is set from a cyclic timer that always runs
when the drive has supply voltage. When the timer reaches its maximum value of
600 hours, it is reset. This function gives a relative time between alarms but no absolute
time. The alarms in the alarm log are kept between power off and power on, but the timer
is reset on each power off. For more information about alarm log entries, see the
P0-50:Alarm log in Software parameters (page 52). See also P0-13:Trip log in Fault
codes (page 47).
Alarm state
The alarm code in P1-19:Alarm state is the sum of all active alarms.
When an alarm is reset but still active, the alarm disappears from the relay output, display,
and the P1-19:Alarm state parameter. Each item in the alarm register corresponds to one
alarm. The last information in each item shows if the alarm is reset or if it is a new alarm.
For active alarms, 16 is added to the sum of active alarms. For example, if the alarms
