SF Series Lock-up – Lock-up After Brief Power Interruption
Product: SF Series
Problem: Logic does not properly reset after momentary power interruption
On certain units of the SF 150, 250, 300, 400 and 500 series a very brief momentary interruption in the AC power line may cause the unit not to return to a normal operating status. This is not a problem if the power is off for more than a few seconds, since this gives the logic plenty of time to reset all parameters.
Symptoms are that there are no front panel alarms, the fans are running, but no power is applied to the driver. Please contact BEXT for further assistance.
