System Overview

Infusomat® fmS 2.3 gb 1 - 7
Mains Operation When the unit is connected to mains the unit supply voltage is
switched on for the duration of the switch-off delay time. If the
microprocessor recognizes a sufficient mains voltage for charg-
ing, the voltage supply is maintained. In this case only a battery
balance is carried out, because a key was not pressed. The current
battery capacity and the battery operting hours are displayed in
the LCD. The unit is switched off when the ON/OFF key is pressed
for at least 2 seconds. Thereby the self-holding is triggered and
the alarm latch is reset with a delay. After another 20 seconds the
unit is switched off, because the pulses are missing. If the Infuso-
mat® fmS is switched off in mains operation with the ON/OFF key,
the internal mains voltage is still present.
