10.2 LED operation indicators
Three light-emitting diodes (LED) indicate the status of the
pump.
Green:
Operation and stroke indicator
In Auto mode, the green LED indicates the operational readi-
ness of the pump. It works in combination with a stroke indica-
tor; during pump operation, the LED flashes in accordance with
the current stroke frequency.
Yellow:
Operation and pre-alarm indicator
In manual operation, the yellow LED lights steadily.
If the level monitoring is connected, the pre-alarm is indicated
by a flashing yellow LED.
Red:
Stop and dry run indicator
If the pump was stopped (manually or via external stop), then
the red LED lights steadily. If the level monitoring is connected,
the dry run is indicated by a flashing red LED.
In case of type
RS 204.1
, the red LED lights also when the
vent valve opens.

NOTE !
The “dry run” error message suppresses the “pre-alarm”
message. This means that if the pump runs dry while the
2-stage level monitoring is activated, then only the red
LED will flash.
10.3 Key operation
Operation of the pump is performed with 2 keys:
START
STOP
STOP/START key
After connection to the power supply, the pump is switched
ON/OFF using the STOP/START key.
AUTO
MANU
AUTO/MANU key
The AUTO/MANU key is used for selecting between Manual
and Auto operation (external control).
In case of type
RS 204.1
, this key is also used to activate
manual venting (see Chapter 10.7.1).
10.4 Stroke length adjustment
Using the knob for stroke length adjustment, you can mechani-
cally adjust the effective stroke to a value between 0…100%.
CAUTION !
Stroke length adjustment may only be performed while the
pump is running.
