Selection Guidelines
-
When to choose: Applications requiring comprehensive power monitoring, power quality analysis, and breaker/contactor control.
-
Voltage Monitoring: Connect voltage sensors (PTs) to voltage inputs.
-
Current Monitoring: Connect current sensors (CTs) to current inputs.
-
Power Quality Analysis: Configure harmonic analysis parameters in Toolbox ST.
-
Control Outputs: Use for breaker trip/close or contactor control.
-
DNP3 Configuration: Configure for substation communication.
-
Compatibility: Fits all Mark VIe VME64x racks. Requires ControlST v6.5 or higher.
Operational Precautions
-
Wiring: Follow GE wiring diagrams—correct polarity for voltage, current, and control connections.
-
Voltage/Current Inputs: Verify PT/CT ratios and scaling during commissioning.
-
Power Quality Testing: Verify harmonic analysis and THD readings.
-
Breaker Control Testing: Test trip/close outputs during commissioning.
-
LED Diagnostics: Green = normal; Amber = fault; Red = module fault.
-
Fault Log: Access 500-event log via Toolbox ST—review power quality snapshots.
-
Hot-Swap: Remove/insert slowly under power.
-
Spare Stock: Maintain 1 spare per 3–4 racks.
-
Firmware Updates: Ensure the GE IS215PCMIH1A is in “standby” mode.
-
ESD: Handle by edges with grounded wrist strap.
