The custom notification provides the capability to define notifications for any points for the early detection of faults.
To navigate to the Custom Notification dashboard from the home page, click View Chiller next to a chiller in the Chiller Status table or click a chiller from the navigation tree. On the Chiller dashboard, click the Custom Notification tab.
Name | Description |
---|---|
Category |
Category includes all the points covered under each component of the chiller. Click the Add icon to expand the list of points inside the category. The points included are only real time points, it does not include any calculated points (like CPI), external API points (Weather data), or physical readings data points. |
Point Description |
The point description lists available data point descriptions under each category. For example, in the Evaporator category, there are points like evaporator pressure, evaporator saturation temp, and evaporator small temp difference. |
Low Limit |
The low limit indicates the lower threshold that you can set up for notifications. It is the minimum of the range that you can configure. |
High Limit |
The high limit indicates the upper threshold that you can set up for notifications. It is the maximum of the range that you can configure. |
Operating Range |
The operating range is a reference range that can be set up by an admin or user for reference. The operating range is optional and not mandatory, it is used as a point of reference. |
Unit |
The unit indicates the unit of the points. The unit is configured by the unit selected on the site setup
form (SSF):
This is a non-editable section. The references are based on the inputs of SSF. |
Primary Condition |
The primary condition checks if the chiller is on or off. For water-cooled chillers, the primary condition is % MOT- FLA. For scroll chillers you should check if any of the compressors are running. The purpose of the primary condition is to check if the chiller is online or offline. Many of the thresholds should be executed only if the chiller is on, so there is a primary condition available that can be enabled on the thresholds. There are options to edit the value of the primary condition. There is an option in the table for select primary condition to be applied to all categories and points. Select the Primary Condition box to indicate that the primary condition is applicable. Clear the checkbox to indicate that the primary condition is not selected for point of the category. |
Pre-Condition |
A pre-condition is an additional check that can be checked for the points in addition to the primary condition. If there are any pre-populated conditions set up, the pre-condition appears in the list. To add a new pre-condition, click Add Pre-Conditions. For more information see Adding pre-conditions. |
Time Delay |
The time delay allows for conditions to be checked for a period of time. From the Time Delay list, select the intervals of minutes: 0, 15, 30, 45, 60, and 120. When you select a time delay for any point, a window opens where you can apply the same time delay to all points. Select Yes or No. If you want to reset the time delays, click Reset. The time delay selection allows the rule engine to check for the entirety of the time range selected for any breach of the threshold condition. For example, if you select a 15-minute time delay for an evaporator pressure with an upper and lower limit, the rule engine checks if the thresholds (upper or lower limit) are breached for a time of 15 minutes and if the condition is true, a notification is sent out. |
Click Edit to edit any notifications. When you enable the edit button you can make changes to the notifications.
