Alarm Configuration

Both the Over Temperature (Initial Threshold) alarm and the Over Temperature (Critical Threshold) alarm offer the following parameters:

•Trigger Enable: Enables/Disables the trigger for this alarm. When Disabled, this alarm will be suppressed. (Default = On.)

Note: To cancel an alarm without correcting the condition that caused the alarm, simply toggle the Trigger Enable parameter Off and then back On again.

•Alarm Set Threshold: The trigger level for this alarm. When temperature exceeds the Alarm Set Threshold, the MPC can send an alarm (if enabled) and/or begin Load Shedding (if enabled.) For more information on Load Shedding for the Over Temperature Alarm, please refer to Section 7.2.1. (Initial Threshold: Default = 90°F or 32°C, Critical Threshold: Default = 100°F or 38°C.)

•Alarm Clear Threshold: Determines how low the temperature must drop in order for the Alarm condition to be cancelled and for Load Shedding (if enabled) to occur. For more information on Load Shedding for the Over Temperature Alarm, please refer to Section 7.2.1. (Initial Threshold: Default = 80°F or 27°C, Critical Threshold: Default = 90°F or 38°C.)

Note: The System Parameters menu is used to set the temperature format for the MPC unit to either Fahrenheit or Celsius as described in Section 5.3.

•Resend Delay: Determines how long the MPC will wait to resend an email message generated by this alarm, when the initial attempt to send notification was unsuccessful. (Default = 60 Minutes.)

•Notify Upon Clear: When this item is enabled, the MPC will send additional notification when the situation that caused the alarm has been corrected. For example, when Notify Upon Clear is enabled, the MPC will send initial notification when it detects that the temperature has exceeded the trigger value, and then send a second notification when it determines that the temperature has fallen below the trigger value. (Default = On.)

•Email Message: Enables/Disables email notification for this alarm. (Default = On.)

Note: The Email Message parameter offers four different options: On, Off, On (Copy to All Triggers) or Off (Copy to All Triggers). If either of the "Copy to All Triggers" options is selected, then email notification for all other alarms will be switched On or Off as indicated by this parameter. For example, If "Off (Copy to All Triggers)" is selected, then Email notification will be disabled for all other alarms too.
