Spectrum Controls 1771sc-IMI16 - Manual (Page 7)

Using the Indicators
For Troubleshooting
The front panel of your module contains one green module active indicator and
16 red channel active indicators (Figure 4). After successfully communicating
with the PLC, the module will illuminate the green module active indicator.
The 16 red status indicators illuminate when the associated input channel is
active (on).
This module contains no user-serviceable parts, and should be returned to the
factory for repair if necessary.
Note that these modules contain components which are susceptible to damage
from electrostatic discharge (ESD). An electrostatic charge can accumulate on
the surface of ordinary plastic wrapping or cushioning material. In the unlikely
event that a module should need to be returned to Spectrum Controls,
please ensure that the unit is enclosed in approved ESD packaging (such
as a static-shielding / metallized bag or black conductive container).
Spectrum Controls reserves the right to void the warranty on any unit that is
improperly packaged for shipment.
For further information or assistance, please contact your local distributor, or
call the Spectrum Controls Customer Satisfaction department at (425) 746-
9481 from 8:00 A.M. to 5:00 P.M. Pacific Time.
