CONTACTS PORT
The contacts port is formed using eight (8) pins numbered from left to right (see fig. 9), which can be connected to an external
monitoring system (such as a BMS) in order to monitor the operational status of the ATS.
The external equipment must respects the voltage and current characteristics of contacts port.
Fig. 9: Focus on contacts port.
The contacts port provides the following pins:
Pin 1: supplies +12V d.c. and a maximum 100mA current usable as user needs.
Pin 2: GND.
Pin 3: common contact.
Pin 4: “INPUT B” active contact (if the contact between “pin 4” and “pin 3” is closed, output is supplied by “INPUT B”).
Pin 5: “INPUT A” active contact (if the contact between “pin 5” and “pin 3” is closed, output is supplied by “INPUT A”).
Pin 6: “INPUT A” OK contact (if the contact between “pin 6” and “pin 3” is closed, “INPUT A” is present and regular).
Pin 7: “INPUT B” OK contact (if the contact between “pin 7” and “pin 3” is closed, “INPUT B” is present and regular).
Pin 8: Status OK contact (if the contact between “pin 8” and “pin 3” is closed, ATS functioning status is regular).
The following diagram shows the fuctioning of the contacts port.

ATTENTION: the pins of the contact port are able to carry a 1A maximum current and 48V maximum voltage.
