LOW AIRFLOW
Airflow is low. Check fans and air filter for obstruction.
CLEAN YOUR FILTER
This is a reminder to clean your air filter. It appears
when the “Clean Time” clock has counted down to
zero.
Reset the “Clean Time” counter to the
number of hours you want between filter
cleaning.
PHASE (A, B or C)
HEADROOM
Incoming line voltage on phase (A, B or C) has dipped
below the configuration-defined Headroom level.
Reduce the load on the indicated phase
through repatching or lowering output
levels of associated dimmers.
CONFIG MISMATCH __
Configuration error.
Transfer configuration data from another
rack.
DIM__BRKR _TRIP
The circuit breaker on dimmer ___ has tripped.
Check circuit for cause of circuit breaker
trip, such as too many lamps on the
dimmer, or bad cabling.
SCR __ STUCK ON
The SCR in dimmer ___ has failed on. Replace dimmer module.
RCD __ TRIP
The RCD in ___ has failed tripped. Replace RCD module.
DIM __ REMOVED
Module has been removed from the rack. Reinsert or replace module.
LOAD __ CHANGE HIGH
Load is currently higher than the recorded load for this
dimmer.
Rerecord the load, or check for additional
or higher wattage lamp(s) on the circuit.
LOAD __ CHANGE LOW
Load is currently lower than the recorded load for this
dimmer.
Rerecord the load, or check for missing or
burned-out lamp(s) on the circuit.
LOAD __ NO LOAD
A load is recorded, but there is currently no load
present on this dimmer.
Rerecord the load, or check for missing or
burned-out lamp(s) on the circuit.
BACKPLANE COM ERR
Lack of communication between CEM+ and
backplane
Power down the rack and re-seat the
CEM+.
CONFIG CHANGE FAIL
Change made to group configuration is not valid
For common causes, see note below.
Review any edits and correct invalid
requests. Re-send configuration to group.
Note:
Common causes for a configuration to be rejected and subsequent configuration
failure notification are:
• ELV or HELV modules with a mode set to something other than “reverse
phase” or “off”
• Minimum volts for a dimmer set are greater than the maximum scale volts
• Two dimmers in the configuration with the same dimmer number
• A controllable dimmer with a number of “0”
• An uncontrollable dimmer with a number other than “0”
• And EDMX or sACN port with data loss behavior set to “crossfade to”
• DMX Port B output enabled but DMX Port B is not enabled in the last rack
• A configuration with more than 1536 dimmers including DMX Out
• A configuration with dimmers patched to more than 4 sACN universes
For assistance with determining or correcting any of these issues, contact ETC
Technical Services.
