OPERATION
CONTROL
The Eaton 2DD Smartwire I/O pack produces both an input and an
output when connected to a robotic welding cell. When the unit is
powered on and operating, the remote output will produce a
24VDC "running" signal. If dry contact is made between the input
and 24V source line the Fan Running Light will illuminate green.
Starting remotely prevents the local panel button from stopping
the unit, as a maintained start signal will take precedence. For
further details consult the "Smartwire Connections Diagram" in
section "F" of this manual.
NOTE: when the unit's Alarm Light is illuminated the remote
output will change to a pulsing high/low at a rate of approx-
imately 1hz. For remote activation, the Robotic Welding Cell
start/stop simulator feature may be utilized (see section "F" of this
manual).

Functions
A. POWER
Light (white): indicates the unit has power, is online,
and available for operation. Blinking light indicates that filter
cleaning is in progress.
B. ALARM
Light (red): indicates one of two potential issues with
the unit. Blinking light indicates the filter differential pressure
has surged above the maximum DP Alarm set point for two
hours continuously and the filter should be changed. Solid
light indicates that the fan's Variable Speed Starter (VSS) has
faulted.
C. FAN RUNNING
Light (green): indicates the unit is operational
and fan is running.
D. RESET DRIVE ALARM
Button: resets the VFD fault. Review the
Troubleshooting Section for further information on this
feature.
E. START/STOP FAN
Button: starts the fan operation when the
unit is online, and also stops the fans if already operational.
NOTE - Fans will NOT stop if the unit has been remotely started.
