Maximum Pumps Running
This function defines the maximum number of pumps that can be run at the
same time.
Maintenance Run
This function is used to prevent prolonged periods of inactivity that degrade the
pump. The function triggers the pump to run after defined periods of inactivity.
Power On Delay
When multiple pumping stations are powered on at the same time, there is a
risk of a main power overload. To avoid the same start time, for example after a
power failure, a random start delay is applied to all pumps.
5.4 Profiles
This function requires use of analog sensors. There are four profiles.
The profiles activate different behavior of the pumping station depending on
the time of day, for example, to take advantage of lower nighttime energy tariffs.
A manually activated profile can be used for site visits or maintenance runs.
The parameters that are included in the profiles are also available in the other
levels of the menu system. When these parameters change, for example the
stop level, the profile that is active also takes on the same changes. The
parameters for Profile 1 are affected because this default profile is used most
frequently.
The time parameters define the daily timer that activates and deactivates the
profile.

5.5 Alarms
The alarm function monitors the status of a pumping station. Severe alarm
conditions can start or stop the pumps for protection, and raise alarms.
5.5.1 Alarm lamp and buzzer
A +24 V output is provided to control an alarm lamp and/or a buzzer.
The alarms that are activated for this function trigger the output signal.
5.5.2 Relay output
The control relay is an output that is provided for general purposes. The alarms
can be configured to activate the relay.
