Contact Ports
The contacts port is formed using six (6) pins numbered from left to right (see fig.
1), which can be connected to an external monitoring system (such as a BMS) in
order to monitor the operational status of the ATS 16.
The external equipment must respect the voltage and current characteristics of
contacts port.

The contacts port provides the following pins:
•Pin 1: common contact.
•Pin 2: “Source B” active contact (if the contact between “pin 1” and “pin 2” is
closed, output is supplied by “Source B”).
•Pin 3: “Source A” active contact (if the contact between “pin 3” and “pin 1” is
closed, output is supplied by “Source A”).
•Pin 4: “Source A” status OK contact (if the contact between “pin 4” and “pin 1”
is closed, “Source A” is present and regular).
•Pin 5: “Source B” status OK contact (if the contact between “pin 5” and “pin 1”
is closed, “Source B” is present and regular).
•Pin 6: Status OK contact (if the contact between “pin 6” and “pin 1” is closed,
ATS 16 functioning status is regular).

ATTENTION: The pins of the contact port are able to carry maximum current of
8A and maximum voltage of 250Vac.
