To perform RCM self-test for additional inlets, press / or

RCM SNMP Operations
Make sure you have the correct version of SNMP MIB. The PX3 supports
the RCM feature as of firmware version 2.5.20. See
Downloading SNMP
MIB
(on page 439) for details.
RCM Trap
An
InletSensorStateChange trap is sent when the RCM state sensor
changes.
InletSensorStateChange is the generic trap sent for all inlet
sensors. The specific trap for RCM has the object typeOfSensor set to 27.
Included with the trap are measurementsInletSensorValue (the residual
current value) and
measurementsInletSensorState (the RCM state that
caused the trap).
RCM Residual Current and State Objects
The
inletSensorMeasurementsTable contains entries for RCM residual
current and states.
Use index sensorType = 26 to retrieve the row for residual current.
Column measurementsInletSensorValue contains the residual current.
Use index
sensorType = 27 to retrieve the row for RCM state. Column
measurementsInletSensorState contains the RCM state enumeration
value.
Setting RCM Thresholds
The inletSensorConfigurationTable contains a row for configuring RCM
thresholds. Use index
sensorType = 26 to reference the row. Columns
inletSensorUpperWarningThreshold, inletSensorUpperCriticalThreshold
and
inletSensorHysteresis set values for RCM warning, critical and
deassertion hysteresis respectively.
Note: The PX3 triggers events when residual current values are above
(but not equal to) thresholds. For example, you would set the critical
threshold to 29mA to specify the IEC 62020 IΔn of 30mA. See
Compliance with IEC 62020 (on page 706).
Running RCM Self-Test
To initiate RCM self-test using SNMP, set column
rcmState to value 29 in
table
rcmSelfTestTable.
