B: Freeway 1300 LED Panel and Alarm Functions
DC 900-1537B 65
When an audible alarm is heard, check the LED indicator panel to determine the source
of the fault condition. If the fault condition is a fan, temperature, or voltage out of tol-
erance condition, you should schedule a maintenance shutdown as appropriate to cor-
rect the fault.
If all indicators on the LED panel are green and the alarm is sounding, one of the power
supplies is defective. The red LED that is illuminated on the rear of the Freeway indi-
cates which of the two power supplies must be replaced. Appendix C describes how to
replace a power supply.
