Priming button
The pump control panel incorporates a button.
Press this button if the maximum capacity is required
over a short period, e.g. during start-up. When the
button is released, the pump automatically returns to
the previous operating mode.
When the buttons and are pressed simultane-
ously, the pump can be set to run for a specific number
of seconds at maximum capacity. The remaining
numbers of seconds will appear in the display. This
feature is useful when flushing the pump. The
maximum value is 300 seconds.
Press to stop the pump before the set time has
passed.
Indicator lights and alarm output
(DME 2 to 48, DMS)
The green and red indicator lights on the pump indicate
operation or fault.
In control variant AR, the pump can activate an external
alarm signal by means of a built-in alarm relay. The
alarm signal is activated by means of an internal poten-
tial-free contact.
The functions of the indicator lights and the built-in
alarm relay appear from the table below.
