Internal Events

Asset Alarm

This alarm is triggered under the following conditions:

• When the Number of Contactor Cycles value for a starter or SILSafety Integrity Level according to standard IEC 61508.* starter on the island exceeds 90% of the life of the device (as calculated based on a combination of multiple factors, including the utilization category, voltage, and FLA setting)

• When the Mirror Relay Operations Counter for a SIL interface module (SIM) on the island equals or exceeds 90% of the life of device (100,000)

Corrective Action:

Check the device diagnostics for each device. The one triggering the alarm is the one with the highest number of operations. Schedule maintenance to replace it.

Device Temp Threshold Alarm

Device temperatures are monitored by reading their internal temperatures. A device internal temperature alarm is triggered for a device if the internal temperature read exceeds its defined threshold.

Corrective Action:

Verify that the equipment design meets the ambient temperature requirements for the product. Cycle the island power. Replace the device if cycling power is unsuccessful in clearing the alarm.

CPU Load Alarm

Triggered when the CPU load read from the device exceeds 60%.

Corrective Action:

Cycle power. If the alarm is still present, contact your next level of support. The device may need to be replaced.

Avatar Alarm

A device within the avatar has experienced an internal event such as the following:

• Communication Event

• AFE Communication Loss

• Control Voltage Out of Range

• DAC Communication Loss

• DAC Over Temperature

• DAC Output Event

Corrective Action:

Cycle power. If the alarm is still present, contact your next level of support. The device may need to be replaced.

Device Data Not Updated Alarm

Indicates a potential perturbation of communication between devices.

Corrective Action:

Verify that all installation guidelines are followed in the setup of the equipment.
