Displays and messages
Tripping of the inverse-time delayed overload release and the short-time delayed overcurrent
release is shown by the displays and messages in the table below.
Table 12- 2 Overload release (displays and messages)
3RA61/3RA62
3RA64/3RA65
(Device version with IO-Link)
•
The mechanical "overload release" display
(TRIP ) is white.
•
The "Group error" LED is red.
•
The signaling contact "Overload" indicates
overload (contact 95/96 is open and contact
95/98 is closed).
•
The message "overload tripped" is signaled to
the controller via IO-Link.
Short-circuit release is signaled by the displays and messages in the following table.
Table 12- 3 Short-circuit release (displays and messages)
3RA61/3RA62
3RA64/3RA65
(Device version with IO-Link)
•
The handle is in the TRIPPED position and
•
The handle is in the TRIPPED position and
•
The "Fault" signaling contact 95/96 is open.
•
The "Group error" LED is red and
•
The message "circuit breaker tripped" is
signaled to the controller via IO-Link.
