4-48 Description of Features
1503-UM054C-EN-P – June 2013
The 7-segment display will display the flashing character ‘7’ +
‘Decimal Point’.
Watchdog Timeout – Fatal Error
This is a fatal Fault condition which indicates that the
Enhanced module program has crashed and is no longer
executing correctly. In this case the watchdog timer has been
allowed to time out.
The 7-segment display will display the flashing character ‘8’ +
‘Decimal Point’.
The IntelliVAC Plus unit has eight (8) hardware inputs that can be
programmed either for use by DeviceLogix (see Chapter 9) or for use
by external devices on DeviceNet.
Each of the eight (8) inputs has an associated Yellow LED on the
front panel of the IntelliVAC Plus unit. The LEDs will turn on when
the corresponding hardware input has a valid input voltage. For a
description of the voltage levels which will cause the input LEDs to
turn on see Table 3.A.
The IntelliVAC Plus unit has two (2) hardware outputs that can be
programmed either for use by DeviceLogix (see Chapter 9) or for use
by external devices on DeviceNet.
Each of the two (2) outputs has an associated Yellow LED on the front
panel of the IntelliVAC Plus unit. The LEDs will turn on when the
corresponding hardware output has been turned on. For a description
of the load ratings which the outputs can sustain see Table 1.B.
