Protective Trip and Warning Functions
•
Any relay outputs configured as a Control Relay open
•
Any relay outputs configured as a Trip Alarm close
•
Any relay outputs configured as a Normal Relay are placed in their
Protection Fault state (if so programmed)
Start Inhibit Protection
This protective function allows you to limit the number of starts in a given time
period and limit the operating hours for an electric motor. A start is defined as
the E300 Electronic Overload Relay sensing a transition in current from 0 A to
30% of the minimum FLA rating of the device. The Blocked Start protective
function is set by Starts Per Hour (Parameter 205) and/or Starts Interval
(Parameter 206).
Blocked Start Trip
The E300 Electronic Overload Relay trips with a blocked start trip indication if:
•
No trip currently exists
•
Blocked Start Trip is enabled
•
The number of starts within the past hour equals the value set in Starts Per
Hour (Parameter 205)
•
The time between starts is less than the value set in Starts Interval
(Parameter 206)
IMPORTANT
The Protection Fault State of Relay 0, Relay 1, Relay 2, Digital Module 1 Output
Relays, Digital Module 2 Output Relays, Digital Module 3 Output Relays, and
Digital Module 4 Output Relays are defined by the respective parameters:
•
Output PT00 Protection Fault Action (Parameter 304)
•
Output PT00 Protection Fault Value (Parameter 305)
•
Output PT01 Protection Fault Action (Parameter 310)
•
Output PT01 Protection Fault Value (Parameter 311)
•
Output PT02 Protection Fault Action (Parameter 316)
•
Output PT02 Protection Fault Value (Parameter 317)
•
Output Digital Module 1 Protection Fault Action (Parameter 322)
•
Output Digital Module 1 Protection Fault Value (Parameter 323)
•
Output Digital Module 2 Protection Fault Action (Parameter 328)
•
Output Digital Module 2 Protection Fault Value (Parameter 329)
•
Output Digital Module 3 Protection Fault Action (Parameter 334)
•
Output Digital Module 3 Protection Fault Value (Parameter 335)
•
Output Digital Module 4 Protection Fault Action (Parameter 340)
•
Output Digital Module 4 Protection Fault Value (Parameter 342)
