Alarm Configuration

7.8. The Plug Current Alarm (VMR Only)

The Plug Current Alarm allows you to monitor current consumption at each of the VMR's

switched outlets and generate an alarm when current exceeds a user-defined "High"

threshold or falls below a user-defined "Low" threshold. The Plug Current Alarm can

also be applied to user-defined Plug Groups in order to generate an alarm when total

current consumption for the given Plug Group rises too high or falls too low.

Note: Current and Power Monitoring features are not available on NPS units.

If desired, the Plug Current Alarm can also be configured to automatically shut off

individual plugs or user-defined Plug Groups, whenever current consumption rises

above a user-defined threshold value.

To configure the Plug Current Alarm, access the VMR command mode using a

password that permits Administrator Level commands and then use the Alarm

Configuration menu to select the desired alarm feature. The Plug Current Alarm allows

the following parameters to be defined:

• TriggerEnable: Enables/Disables the trigger for this alarm. When Disabled, this

alarm will be suppressed. (Default = On.)

• PlugHysteresis: This parameter can be used to prevent the Plug Current

Alarm from generating excessive "Alarm" and "Clear" messages when current

consumption fluctuates back and forth across the trigger value. Basically, the Plug

Hysteresis parameter allows you to define a margin at both the Low Threshold and

High Threshold that the current level must cross in order to clear an alarm.

(Default = 0.5 Amps)

Plug Hysteresis Example: Assume that the Low Threshold for Outlet A1 is set at 5

Amps, the High Threshold is set at 12 Amps and the Plug Hysteresis value is set at

1 Amp. When the current goes high or low, the VMR will respond as follows:

• Low Alarm: If the current drops below 5 Amps, the VMR will generate an Alarm.

The Alarm will not be cleared until the current rises above 6 Amps

(5 Amp Low Threshold + 1 Amp Hysteresis Value = 6 Amps.)

• High Alarm: If the current rises above 12 Amps, the VMR will generate an Alarm.

The Alarm will not be cleared until the current drops below 11 Amps.

(12 Amp High Threshold - 1 Amp Hysteresis Value = 11 Amps.)

• PlugThresholds: Defines current consumption level(s) that will trigger alarm(s) at

each switched outlet. The Plug Thresholds can be configured to trigger an alarm

when current consumption rises above a user-defined "High" value and/or when

current consumption falls below a user-defined "Low" value. This allows you to

define a "normal" current range for each outlet, allowing the Plug Current Alarm to

be triggered whenever current consumption strays outside of this range.

(Default = undefined.)
