Step 8 PNP/NPN mode selection
The L100 inverter supports PNP (Source) and NPN (Sink) modes to sequence
input current at the terminal. Select an appropriate mode to suit the circuit by
switching the PNP/NPN switch (SW1) on the control board. Refer to the
following information for more details. (Default: NPN)
PNP mode (Source)
Select PNP mode at the PNP/NPN switch (SW1). The default setting is NPN
mode. CM is the common ground terminal for all analog inputs at the terminal
block and P24 is the internal DC 24 V supply. If you are using an external DC 24
V supply, build a circuit that connects the external power supply (-) and the CM
terminal.
The guaranteed input voltages in the PNP mode (when using an external DC 24
V supply) are DC 19 to 25.2 V when the inverter is ON and below DC 7 V when
the inverter is OFF.
