Protective Trip and Warning Functions
Chapter 6
Analog-based Protection
The E300 Electronic Overload Relay’s Analog I/O Expansion Modules scan up
to three analog signals per module. This information can be used to trigger an
over analog level Trip or Warning. The analog-based protection features can be
used with the following analog applications:
•
Monitoring motor winding and bearing temperatures that are measured by
RTD sensors
•
Monitoring liquid, air, or steam flow
•
Monitoring temperature
•
Monitoring weight
•
Monitoring levels
•
Monitoring a potentiometer
•
Monitoring PTC or NTC thermistor sensors
Analog Trip Enable (Parameter 187) and Analog Warning Enable (Parameter
193) are used to enable the respective analog-based protective trip and warning
functions.
