Chapter 10—Alarms PowerLogic™ PM5500 series user manual

Alarms setup overview

You can use the meter display or ION Setup to configure unary, digital or standard (1-Sec) alarms. To configure logic and custom alarms, you must use ION Setup.

NOTE: If you make changes to the basic power meter setup, all alarms are disabled to prevent undesired alarm operation.

NOTICE

UNINTENDED EQUIPMENT OPERATION

After modifying any basic setup parameter:

•Verify all standard alarms settings are correct and make adjustments as necessary.

•Re-enable all configured alarms.

Failure to follow these instructions can result in incorrect alarm functions.

Built-in error-checking

ION Setup dynamically checks incorrect setup combinations. When you enable an alarm, you must set up the pickup and dropout limits to acceptable values first in order to exit the setup screen.

Alarm priorities

Each alarm has a priority level. Use priorities to distinguish between events that require immediate action and those that do not require action.
