CEM+ Status Messages
If the CEM+ detects an error, it will flash the beacon and display the appropriate error message on the
LCD display. A CEM+ will only display error messages for the same rack it is in. You can't see other
rack's error messages from a single CEM+.
Errors are also displayed in the WYSILink Message Log on Emphasis Control Systems and WYSILink PCs
on the network. You can also view rack error messages in the Sensor+ Connect interface on Emphasis
Control Systems or by browsing into a CEM+ using Internet Explorer 6 on a PC on the network.
View error messages on the CEM+ LCD display:
1. Open the door of the rack with the blinking beacon. The CEM+ will display the message [Rack
Errors].
2. Press
that number are displayed at the top of the display.

Possible Corrective Action
Lower dimmer room temperature.
Lower dimmer room temperature.
Raise dimmer room temperature.
Use About Dimmer to check the specific
error.
Check DMX512 port input cable and
termination.
Check input frequency.
Check fan and air filter for obstruction.
Check DMX512 source devices and input
cables.
Check airflow
Check line feed.
Re-seat the CEM+ and try again. If
problem persists, replace the CEM+.
