8.2.1 Operating mode selection
MAGDOS DE
The rotary switch
⑥
defines the stroke rate (0..100/min) infinitely variable in internal mode.
External mode is activated by turning to the left-hand stop (beyond the detent). A dosing stroke is executed
for every incoming pulse in external mode.
IMPORTANT!
Pulses are not saved when the dosing pump is driven at more than the maximum pulse rate (see Technical
Data). When driven at higher pulse rates, the pump does not continue running at a constant maximum
frequency but rather dosing strokes are omitted.
MAGDOS DX
In addition to the functions of the MAGDOS DE, optional functions can be selected for external operation
with the MAGDOS DX. The additional selector switch has the following settings:
①
Pulse 1:1
②
Pulse multiplication 2 / 4 / 8 / 16 / 32 / 64
③
Pulse division 2 / 4 / 8 / 16 / 32 / 64
④
Signal input 0..0.20 mA or 4..0.20 mA
⑤
Pump stop at “0”
8.2.2 Digital display (optional)
The display shows the different operating modes and possible error messages.
