Here below there is a typical connection of the START/STOP input to
an external system output.
The pump operation is I/O signals dependent so you must always plug-in the
NOTE
provided mating connector to start the pump.
MS120 Single Stage Rotary Vane Pumps User Manual/87-900-150-01 (C.00)
Interlock/Status: N.O. Solid State Relay contact – It is closed as
soon as the rotational frequency exceed the threshold defined
with Win102 (plus histeresys defined by Win105 as % of Win102).
START/STOP: If the inverter is managed by remote signals, it
commands the pump starting. This Input is 0.24V active high. To
activate the input (and starting the pump) it should be tied to
24Vdc (pin9), a non active state could be obtained either leaving
the input not connected or connecting it to GND.
More in detail:
- Active state:
- Non Active state: Vinput ≤ 4V or Isink ≤ 0.1 mA
