Excitation Failure Detection
About Excitation Failure Detection
The Limits tab for each channel input allows you to set upper/lower limits and actions, and Excitation Failure
Mode and action settings.
Note:
You can also use the Station Setup Limit Detectors panel (listed under Detectors) to set limits and
actions for all inputs.
Series 493 and 494 Conditioners include circuits that can detect an excitation failure. The most common
cause of an excitation failure occurs when you unplug a sensor. Other causes include damaged cables,
sensors, or conditioner hardware.
Settings
You can use the Station Manager application to configure excitation failure detection for each sensor input.
These settings allow you to turn on/turn off excitation failure detection and define the action taken (Series
494 Hardware only) if the hardware detects an excitation failure.
Message log
Each time an excitation failure is detected, a message is written to the message log. This occurs even when
excitation failure detection is disabled.
Excitation Failure Mode Settings
You can use the Limits tab on the Station Setup window to set the Excitation Failure Mode for each sensor
input.
