3-2-9. Constant voltage output mode voltage shortage alarm (VPF signal)
Open collector output. Connect the external voltage between the VPF terminal (pin No. 10 of CN71) and the DG
terminal (pin No. 5 or pin No. 7 of CN71).
Use twisted or shielded signal wires.
3-2-10. Constant current output mode current shortage alarm (CPF signal)
Open collector output. Connect the external voltage between the CPF terminal (pin No. 9 of CN71) and the DG
terminal (pin No. 5 or pin No. 7 of CN71).
Use twisted or shielded signal wires.
3-2-11. Input voltage shortage alarm (ACF signal)
Open collector output. Connect the external voltage between the ACF terminal (pin No. 8 of CN71) and the DG
terminal (pin No. 5 or pin No. 7 of CN71).
Use twisted or shielded signal wires.
