When this error is displayed the trip unit uses its lowest
protection settings.
The rating plug error is generated under the following
conditions:
1. The rating plug is not installed.
2. The rating plug is not fully inserted into the trip unit.
3. The rating plug value is outside the range allowed for
the breaker’s sensor. For example, plugging a 4000A
rating plug in a 400A sensor circuit breaker will
generate this error or a 400A plug installed in a 4000A
Sensor Circuit Breaker
4. For IEC or Euro configurations, where the trip unit rating
is set programmatically, use of a rating plug other than
the UNIVERSAL type (The catalog number for a universal
rating plug is GTPUNIVU0000) will generate this error.
What this shows:
A Rating Plug error of some sort exists. The error can be
cleared by installing the correct rating plug.
BIM ERROR MESSAGES
The Breaker Information Module (BIM) is an electronic
rejection feature on EntelliGuard G Breakers only. When a
GTU powers up the first time in contact with a BIM, it
“absorbs” the BIM data and configures itself to match.
From that point forward every time the trip unit is powered
it will compare the data in the BIM against its own stored
values. Any mismatch will cause a BIM error and trip the
breaker.
NOTICE
BREAKER TRIP SOFTWARE REVISION 08.00.23 AND
GREATER.
If a BIM read fails the trip unit will not open the breaker,
instead it will modify its internal configuration to match
the AIC rating of the least capable breaker in the family.
The trip unit will periodically read the BIM after that, and
on a successful match the original settings will be
restored. While the BIM error persists a BIM Err
message will be displayed on the LCD.
What this shows:
There is a mismatch between the Trip Unit’s stored breaker
configuration and the breaker configuration read back
from the breaker’s information module (BIM). This can be
caused by swapping trip units between breakers, or by a
bad connection between the BIM and the trip unit.
BREAKER STATUS INDICATIONS
This is the Breaker Status display.
What this shows:
State of the circuit breaker contacts –
OPEN or CLOSED
Requires 24VDC for this option to
display. On older firmware this value
will be incorrect if the trip unit does
not have an external 24VDC source.
