Regulator function:
Under the settings for AI1 is the regulator function. Here, the most common parameters for the pump
control function are configured.
There are additional functions that can be selected by clicking on the corresponding tabs "Pump settings",
"flow interface" and “additional options”.
Variable start level: By setting a variable start level, you allow the PUMA control itself to select the level for
start, within the limits you have defined. For example: The start level is set to 1m and the variable start level
is set to 0.1m. When the level in the station reaches 1m, the variable start is initiated which can be
depending on 1cm to 10cm. Thereby the pump does not start in the same place twice in succession. The
function can i.a. used in connection with the reduction of fat edge formation.
Antal fejl før pumpe suspenderes: Errors before pump is suspension: The PUMA control uses auto-
acknowledgment of all faults. If the same error occurs repeatedly, all depending on the value entered - for
example overcurrent on the pump, then the pump is suspended, and you must manually reset the error. If
the setting selection is set to 0 then the pump is never suspended.
Leak indicator timer (minutes): Can be used in connection with leakage faults on the inlet pipe. If the setting
choice in minutes exceeds the time between 2 pump starts, then it is assumed that there is a reduced inlet
to the pump station and thereby there is a risk of a leak on the inlet pipe. This is a warning and not an alarm
that can be read on the PUMA status word register 92: bit 12. The PUMA control does nothing but report the
warning, the error has no functional consequence in the control.
Interlocking enabled: Approves that the pump control can interlocked from either SCADA system or via SMS.
Can be put in PUMA status word register 92: bit 20 and read in PUMA pump word register 70: bit 12.
Start level: Here you enter the desired start level for the pump
Stop level: Here you enter the desired stop level for the pump
delay in seconds: The function is used if you want a delayed start-up of the pump. The pump start is delayed,
the entered value in seconds, after the start level is reached. The function is used i.a. in connection with the
mixer function, where you want a function where first the mixer starts up and then it must take some time
before the pump is started.
