Setting up the Trip Unit

Current alarms can be configured to actuate relay outputs
when they go into pickup. They also have status flags that
can be monitored over Modbus.
The ON setting determines the level, as a percent of rating
plug current, where the current alarm will pickup.
If the highest measured phase current exceeds the pickup
threshold for more than 60 seconds, the alarm will activate.
Setting range is 50% to 100%.
Once in pickup, if the highest measured phase falls below
the OFF threshold for more than 60 seconds, the alarm will
drop out.
The Output Relay assigned to the Current Alarm does not
latch. It tracks the state of the current alarm.
The OFF Setting cannot be set higher than the ON setting.
ALARM 1 and ALARM 2 operate identically, and
independently.
NEUTRAL POLE (ENTELLIGUARD G ONLY)
Neutral Pole setting determines the
overcurrent protection setting for the
neutral pole of a 4 pole breaker.
This screen may be displayed on a 3
pole breaker, in which case it is
recommended that it be set to off.
There is no way for a 3 pole breaker
to open the neutral pole, so there is
no added protection provided by
enabling this feature.
The available settings are OFF, 50%,
63%, and 100%. This determines the
percentage of the Long Time pickup setting that will apply
to the neutral pole.
For example, if the Long Time Pickup is set to 1.0 and the
Neutral Pole is set to 50%, the Long Time Pickup setpoint
for the Neutral is 50%.
The neutral pole screen is not available on PB1, PBII,
WavePro, AK, AKR or Conversion Kit trip units.
BELL ALARM LOCKOUT (PBII AND WAVEPRO ONLY)
WavePro, AKR and PB1 has a factory
installed Bell Alarm with Lockout
option that is triggered by the
mechanism, not the trip unit. So no
special configuration is needed on
AKR or PB1.
PBII fire the lockout on command
from the trip unit.
This screen will appear on Power
Break II trip units only.
The setting defines what functions
will trigger the Bell Alarm with Lockout (the factory default
is 15):
• OFF – Disabled/OFF
• 1 - Shunt Trip
• 2 - UVR Trip
• 3 - Over Current Trip
• 4 - Protective Relay Trip
