Configure one of the Ptxx Input Assignments (Parameters 196…201) to
Emergency Start and activate the corresponding digital input.
Table 52 - Emergency Start (Parameter 216) Input PTXX Assignment (Parameters 196…201)
The user can also use a network command to activate the Emergency Start
feature. For the EtherNet/IP communications module, the user would set the
Emergency Start bit to 1 in Output Assembly 144. See
for more information on EtherNet/IP
communications.
When the Emergency Start feature is active, the following actions occur in the
E300 Electronic Overload Relay:
•
Protection trips are ignored
•
Output relays configured as Trip Relays are put into closed state
•
Normal operation resumes with any Normal or Control Relay assigned
output relay
•
The Emergency Start Active bit is set to 1 in Device Status 0
(Parameter 20) bit 6
