Input and output signals - Time Control
The FlexxPump 125 can be switched off completely by switching off the supply voltage.
The settings will not be lost. The elapsed time until the next scheduled lubrication cycle
is automatically stored by the FlexxPump 125 in the integrated microelectronics. After
reapplying the supply voltage, the FlexxPump 125 automatically checks itself and conti-
nues to operate according to the set values.
After a longer standstill of the FlexxPump 125 the manual execution of the "Quick-
Check" is recommended (chapter 6.3.8).
The output signal at PIN 4 can be tapped for further processing (e.g. indicator light
or external control). The maximum permissible output current must not exceed I
max
<
20mA. No inductive load (e.g. relay) may be connected!
