Input / Output Terminals

External Fault Input (Terminal 1)

The Fault Input terminal permits a fault signal from external equipment to be indicated on the Noby-220i

iR2

control panel. The LED indication is non-latching i.e. the LED follows the Ext. Fault Input status. The

polarity of the input is programmable. The factory setting is for a +12V signal to be applied to the terminal to

bring up a fault indication. Note that connecting external equipment also requires a ground reference

connection i.e. 0V from the external equipment must be connected to 0V on the Noby-220i

iR2 (Terminal 4).

From normal standby User Mode enter the following key sequence:

Engineer Access Code-1 Select Toggle Fault Input Polarity Option

LEDs Off= +12V applied*

LEDs On= +12V removed

* Factory default setting

• The green Power LED flashes rapidly upon successfully entering the Engineer Access Code-1.

• The LEDs surrounding button indicate the current option status.

• Toggle button to set/unset the desired option.

• Press to accept OR press to quit without updating the option.

Fault Output (Terminal 2)

A 12V/20ma open-collector output signal. Normally high (12V), it falls to 0V upon detection of any fault

originating at the local panel only i.e. does not include the Ext. Fault Input, i

interlink bus faults, or any fault

originating at a remote panel. Note that connecting external equipment also requires a ground reference

connection i.e. 0V on the Noby-220i

iR2 (Terminal 4) must be connected to 0V on the external equipment.
