Communication Parameters. The following is list of the parameters that the SMP-3 overload relay can communicate to
an adapter.
[Average Current]
This parameter is the average value of the
three-phase current passing through the SMP-3
overload relay. The accuracy of the average current
reported to a communication adapter is
±
5%
Parameter # 1
Parameter Type Read Only
Units Amps
[FLC Setting]
This parameter is the actual Full Load Current (FLC)
setting established by the eight FLC DIP switches.
Parameter # 2
Parameter Type Read Only
Units Amps
[Thermal Capacity Utilized]
This parameter indicates the amount of the overload
relay’s thermal capacity which has be utilized. The
value is based on the maximum phase of current and
the time it is present.
Parameter # 3
Parameter Type Read Only
Units Percent
[Current Unbalance]
This parameter indicates the level of unbalance
between the three phases of current. The value is
based upon the magnitude unbalance between the
three phases.
Parameter # 4
Parameter Type Read Only
Units Percent
