Alarm Configuration
To configure the Over Current Alarms, 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.
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. The Current Alarm Configuration menus offer the following parameters:
• TriggerEnable: Enables/Disables the trigger for this alarm. When Disabled, this
alarm will be suppressed. (Default = On.)
Notes:
• When an alarm is generated, to cancel an alarm without correcting the
condition that caused the alarm, simply toggle the Trigger Enable parameter
Off and then back On again.
• The Trigger Enable, Notify on Clear, Email Message and Address 1, 2 and 3
Parameters all include "Copy to All Triggers" options that allow you to enable/
disable the corresponding parameter for all VMR/NPS alarms. For example,
if the Over Current Alarm's Trigger Enable parameter is set to "On (Copy to All
Triggers), then the triggers for all other VMR/NPS alarms will also be enabled.
• AlarmSetThreshold: The trigger level for this alarm. When current load exceeds
the Alarm Set Threshold, the VMR can send an alarm and/or begin load shedding
(if enabled.) Note that the Alarm Set Threshold is entered as a percentage of
maximum capacity and is applied to both Over Current Branch Alarm and Over
Current Line Alarm (if present.) (Defaults: Initial = 80%; Critical = 90%.)
• AlarmClearThreshold: Determines how low the current load must drop in order
for the Alarm condition to be cancelled and for load shedding recovery (if enabled)
to occur. The Alarm Clear Threshold is entered as a percentage of maximum
capacity and is applied to both Over Current Branch Alarm and Over Current Line
Alarm (if present.) (Defaults: Initial Alarms = 70%; Critical Alarms = 80%.)
• ResendDelay: Determines how long the VMR will wait to resend an email
message generated by this alarm, when the initial attempt to send the notification
was unsuccessful. (Default = 60 Minutes.)
• NotifyUponClear: When this item is enabled, the VMR will send additional
notification when the situation that caused the alarm has been corrected. For
example, when Notify Upon Clear is enabled, the VMR will first send notification
when it detects that current consumption has exceeded the trigger value, and then
send a second notification when it determines that the current consumption has
fallen below the trigger value. (Default = On.)
• EmailMessage: Enables/Disables email notification for this alarm. (Default = On.)
• Address1,2,and3: These parameters are used to select which of the three email
addresses defined via the "Email Messages" menu (see Section 5.9.11) will receive
the email alarm notification messages generated by this alarm. The Address
parameters can be used to select one, or any combination of the addresses defined
via the Email Messages menu. (Default = All On.)
Note: If Email addresses have been previously defined, then the text under the
parameters will list the current, user selected email addresses.
