Testing an Installed Sensor3 Rack
After finishing installation, use this procedure to perform a functional check.
Step 1:
Make sure power is disconnected at the main circuit breaker.
Step 2:
Open the door and set all the dimmer module circuit breakers to Off.
Step 3:
Remove the CEM3 and set the test switch to TEST.
Step 4:
Replace the CEM3 and close the door.
Step 5:
Apply power at the main circuit breaker
.
Step 6:
Observe the rack for obvious faults:
•
Flashing Sensor beacon
•
Any indication of shorting or burning from rack components
Checking individual dimmer operation
Step 1:
Open the dimmer rack door.
Step 2:
Set one dimmer module circuit breaker to On and check these functional
indications:
•
Signal LEDs on the dimmer modules lit
•
The dimmer’s lighting loads are on (if visible)
•
The rack cooling fan is running
•
Dimmer hum increases slightly
Step 3:
Set the circuit breaker to Off, and repeat
with each dimmer module in the
rack.
If all indications are normal after testing the dimmer modules, the rack is functional.
Step 4:
Remove power at the main circuit breaker.
Step 5:
Open the rack door, remove the CEM3 and set the Test switch to NORM.
Step 6:
Replace the CEM3 and close the rack door.
Step 7:
An Authorized Service Center (ASC) may now configure the CEM3 processor(s)
and test the dimming system using the facility control system.
Step 8:
Deliver all ETC documentation to the system operator.
N o t e :
Go over the Sensor3 installation checklist in
Appendix B: Sensor3 Installation
before energising the rack.
C A U T I O N :
Caution: With the test switch on TEST, all dimmers drive to full output. Your power
supply may not have enough capacity to operate the rack at full output. To avoid
tripping your main circuit breakers, make sure you have set all dimmer module
circuit breakers to Off before applying power.
W A R N I N G :
3-Phase Mains voltage is present inside the rack during this procedure. Do
not remove rack modules when power is applied.
