Loading...How to troubleshoot a Vertiv Control Unit when the power indicator is off?
If the green power indicator on your Vertiv Control Unit is off, it could be due to two reasons. First, there might be no input voltage, so ensure that the unit is receiving power. Second, the internal input fuse might be open, in which case you should replace the rectifier.
What to do if the alarm indicator (red) is on for Vertiv Control Unit?
If the red alarm indicator is constantly on, it indicates a severe load sharing imbalance or that the rectifier output is disabled. To resolve this: turn off AC power to the rectifier (or remove it), wait at least 30 seconds until the LEDs are off, and then restore AC power (or re-insert the rectifier). If the problem persists, the rectifier needs to be replaced. Another possible cause is contradictory rectifier addresses, which also requires replacing the rectifier.
Why is the protection indicator (yellow) on in my Vertiv Control Unit?
A lit yellow protection indicator on your Vertiv Control Unit suggests several potential issues. It could be due to AC input under/over voltage, so ensure the AC input voltage is within the acceptable range. It might also be caused by PFC under/over voltage, or a moderate load sharing imbalance. For the latter, check if the rectifier is properly seated; if not, or if the problem continues, replace the rectifier. Also, ensure the rectifier is fully inserted into its slot. Finally, the rectifier might be in ECO Standby Mode when ECO Mode is active in the controller.
What does it mean when the alarm indicator (red) is flashing on a Vertiv Control Unit?
A flashing red alarm indicator on your Vertiv Control Unit means the fan is not operating, which causes the rectifier to shut down. The solution is to replace the fan.
