Dimmer Module Indicators

LOAD LED ON :   The dimmer is on at some level. This led dims up and down proportionally with the dimmer control level.
LOAD LED OFF : The control to this dimmer is off. The dimmer is off.

 

STATUS LED OFF : There is no DC power getting from the control module (s) to the dimmer module. The dimmer module will not operate.
STATUS LED GREEN : Normal Operation
STATUS LED YELLOW : This dimmer module is in Overtemp Warning.
STATUS LED RED : This dimmer module is in Overtemp Shutdown.
The Overtemp Warning  or Overtemp Shutdown condition would only occur if:
A.  The rack is not fully populated -- with either dimmer modules and / or airflow modules.
B.  The air filters in the door are clogged with dirt / dust.
C.   The rack fan is not operating.
D.  The dimmer rack is operating beyond it's maximum ambient operating temperature specification.

In the unlikely event that a rack encounters an overtemp condition,  is strongly recommended that users minimize rack use, and call technical services at (503) 404-5500 8am-5pm PST if they are  unable to isolate and rectify the cause of this potentially equipment damaging condition.
