Alarm Configuration

7.1. The Over Current Alarms (RSM-8R8-CM Series Only)

The Over Current Alarms are designed to inform you when current consumption reaches

or exceeds user-defined levels. Depending on the specific RSM-8R8-CM model, RSM-

8R8-CM units can have up to four Over Current Alarms (two sets of two alarms):

• The Over Current Line (Initial) Alarm

• The Over Current Line (Critical) Alarm

unitsorstandardRSMunits.

• TheOverCurrentAlarmsmonitortheloadoneachinputline.

The Initial alarms are used to provide notification when the level of current consumption

reaches a point where you might want to investigate it, whereas the Critical alarms can

provide notification when the level of current consumption approaches the maximum

allowed level. The trigger levels for the Initial alarms are generally set lower than the

trigger levels for the Critical alarms.

If the user-defined trigger levels for current load are exceeded, the RSM-8R8-CM can

automatically shut off power to non-essential devices ("Load Shedding") in order to

decrease current load. After Load Shedding has taken place, the RSM-8R8-CM can

also restore power to the non-essential devices when current load drops to user-

defined acceptable levels. For more information on Load Shedding, please refer to

Section 7.1.1.

To configure the Over Current Alarms, access the command mode using a password

that permits Administrator Level commands, and then use the Alarm Configuration

menu to select the desired alarm feature.

Note that the configuration menus for both Over Current Alarms offer essentially the

same set of parameters, but the parameters defined for each alarm are separate.

Therefore, parameters defined for a Critical Alarm will not be applied to an Initial Alarm

and vice versa.
