Diagnostic Relay
A normally closed relay contact, rated at 220 Vac 6 A or 30 Vdc 5 A, is available on
the terminals of the diagnostic relay port via its connector.
The following figure shows the 2 terminals of the diagnostic relay connector:
The contacts of the relay are open whenever an error is detected (internal or
external), and the Fault LED is ON. In fact the status of the diagnostic relay provides
an electric information when the Fault LED status provides a visual status when an
error is detected (internal or external).
