16 External Fault Configuration

Any Router or Remote I/O Unit digital or analogue input may be configured as an external fault input. An active low contact closure o the port indicates a ‘no fault’ condition, and open circuit on the port shall cause a fault to be reported and logged.

16.1 Router Digital Input as External Fault

To Program a Router Digital Input as External Fault Input:

1. Select input and program it for ‘External Fault’.

Menu: ConfigurationÆSystemÆRouterÆCtrlÆContacts

2. Change fault description as required.

Menu: ConfigurationÆSystemÆRouterÆCtrlÆContactsÆExternal FaultÆDesc.

Possible values: 18-character alphanumeric string

3. Any input that is not used should be configured as ‘Not-Conf’.
