Row Bit Definition
1
STARTING Asserts when protected motor is starting (current is greater than 2.5 times motor rated full load current).
RUNNING Asserts when motor is running.
STOPPED Asserts when motor is stopped (current is less than 3% of motor rated full load current).
JAMTRIP Load-Jam Trip.
LOSSALRM
LOSSTRIP
Load-Loss Alarm and Load-Loss Trip. Assert when the relay detects a load-loss as defined by that
function and its settings. These Relay Word bits are inactive if the function is disabled by relay settings.
46UBA
46UBT
Phase Current Unbalance Alarm (46UBA) and Trip (46UBT). Assert when the relay issues an alarm or
trip in response to a current unbalance condition, as defined by that function and its settings.
2
49A
49T
Thermal Alarm (49A) and Trip (49T). Assert when the relay issues a thermal element alarm or trip due
to locked rotor starting or running overload conditions.
THERMLO
NOSLO
TBSLO
ABSLO
Motor Lockout Conditions. Asserted by the thermal element (THERMLO), starts per hour function
(NOSLO), minimum time between starts (TBSLO), and the antibackspin timer (ABSLO).
