• OLIP MCM INVERTER , Motor Current meter

    ◆ Motor Type : 3-phase, AC (not suitable for DC motors), fixed and variable speed motors.

    ◆ Operating Temperature : 0 – 40⁰ C (32 – 104⁰ F)

    ◆ High Voltage Models (>480 Vac) : Three Cat II Voltage Transformers*: 0.5% accuracy; 100 V, 110 V, or 120 V secondary voltages

Features

MCM provides both mechanical (unbalance, misalignment, roller bearings, etc.) and electrical (loose windings, short circuits, etc.) anomaly detection as well as electrical parameters such as voltage and current imbalances and power factor. In addition, it can detect changes in the load the motor is experiencing due to anomalies in the driven equipment or process such as cavitations or plugged filters and screens. Since it doesn’t require any sensor installation on the motor itself or associated load, MCM is especially attractive for inaccessible driven equipment and is applicable to most types of pumps, compressors, and similar loads.

Description

Motor Condition Monitor for Inverter Driven Motors

MCM continuously identifies existing and developing faults on electric motors and their driven equipment. MCM utilizes an intelligent, model-based approach to provide anomaly detection by measuring the current and voltage signals from the electrical supply to the motor. It is permanently mounted, generally in the motor control center and is applicable to 3-phase AC fixed and variable speed motors. Accompanying MCMScada Software or OLIP Enterprise Server (OPC Server) is used to view the data.

Technical Specifications

General Information
Motor Type 3-phase, AC (not suitable for DC motors), fixed and variable speed motors.Motor current (load) and voltage frequency (speed) variation must be less than 15% during 6 sec data acquisition period.
Environmental
Operating Temperature 0 – 40⁰ C (32 – 104⁰ F)
Humidity Up to 90% RH, non-condensing
INPUTS
Power Input Required 100-240 Vac, 47 – 64 Hz, 19 VA, 200 mA or 120-300 Vdc, 19 VA, 200 mA (use UL listed fuse with proper voltage rating)
MEASUREMENT VOLTAGE INPUTS
Low Voltage Models (≤480 Vac) Can tap directly off voltage lines to motor
High Voltage Models (>480 Vac) Three Cat II Voltage Transformers*: 0.5% accuracy; 100 V, 110 V, or 120 V secondary voltages. Voltage Transformers’ frequency range has to cover inverter’s voltage frequency variation.
MEASUREMENT CURRENT INPUTS 3 Hall-effect Current Sensors*: selected based on the power of the motor to be monitored; secondaries to be 50-400 mA output, 30 Vac SELV.Note: Hall-effect Current Sensors need external power sources, generally installed in the motor control panel, too.
