If a load warning condition exists, the corresponding load segment LED with the alarm condition is illuminated amber, while the green load segment LED for that particular load segment is not illuminated. • Voltage Out of Range o Overvoltage of 10% to 20% (amber alarm LED), overvoltage of greater than 20% (red alarm LED) o Undervoltage of 10% to 20% (amber alarm LED), undervoltage of more than 20% (red alarm LED) When an alarm condition occurs, the front panel display automatically changes to show the circuit with the alarm condition, regardless of the present display setting. The automatic scrolling function is disabled when an alarm condition exists. If an alarm condition displays and you scroll to display another circuit that does not have an alarm condition present, the circuit without an alarm is displayed for 10 seconds and then switches back to the alarmed circuit. If an alarm condition displays and you scroll to another circuit with an alarm condition, the display remains on the last circuit selected with an alarm until the alarm condition clears or you scroll to a different circuit. If multiple circuits have alarm conditions at the same time, the last circuit to activate an alarm is displayed. Current alarms NOTE: The values in the table below are expressed in amps. The front panel display does not show values in tenths.
