Do not unplug the connectors of the SP Guard while still being under volt-
age. There exists the risk of igintion!
All connectors are protected against mechanical influences thanks to the
housing covers. Do not operate the pump without its covers!
Outputs at the SP-Guard (S1 - S4)
The outputs S1 - S4 of the SP-Guard are provided with push-pull driver out-
put stages (transistor connection between +Vcc and GND). Correspondingly,
the high level is at 1 V below the power supply voltage level and the low level
is at approximately 1 V.
The maximum current rating is 40 mA.
The outputs are protected by means of semiconductor fuses.
