Alarms

Use alarms to send reports to Remote Manager when unusual changes occur in sensor values. Alarm reports are sent when a sensor reaches an alarm value during a sensor reading, even if it is between reporting intervals.

Connect Tank sends alarm reports as follows:

• High alarm: Sends an alarm report when the input value is greater than the high threshold.
• Low alarm: Sends an alarm report when the input value is less than the low threshold.
• Delta high alarm: Sends an alarm report when the input value increases too much between two consecutive readings.
• Delta low alarm: Sends an alarm report when the input value decreases too much between two consecutive readings.
• Rising edge: Sends an alarm report when the device wakes on a digital input change from low voltage to high voltage.
• Falling edge: Sends an alarm report when the device wakes on a digital input change from high voltage to low voltage.

For example, with high alarms enabled and configured, Connect Tank is configured to read sensor input values every hour and scheduled to send reports twice every day, at 8:00 and 20:00. An input value suddenly reaches its high threshold at 11:00. When Connect Tank wakes at 11:00 to take a reading, it sends a high alarm report to Remote Manager.

Alarms are available for the following:

• Analog: 4-20mA Current Loop Input
• Analog: Voltage Input
• Digital: Input
• Digital: Pulse Counter

For Connect Sensor+, an alarm is also available for the following:

• Modbus protocol: Enable and configure the Modbus protocol
