About the 269PLUS-DO-225-100P-HI-125VDC
269PLUS-DO-225-100P-HI-125VDC is a motor protection relay system from the 269 Plus Motor Protection system series by GE Multilin. This system is intended to be used in conjunction with a variety of 3-phase AC motors. The system provides protection from electrical and thermal harm to the motor via resistor thermal detectors (RTDs) and current transformers (CTs). The power input to the control is either 80- 300 VDC or 65-265 VAC and 50-60 Hz. The maximum power consumption is 20 VA and 100 ms at 120VAC/125 VDC. The RTD sensors for this device are 100 ohm Platinum sensors. They have a display accuracy of ±2°C, and they have a setpoint range 0 - 200°C. The sensors have a dead band at 3°C. The sensors also have 25% of the resistance at 0°C.
Once the system is properly set up, it is ready to be programmed by the user. Programming is completed using the 12-key pad on the front panel. The 48-character alphanumeric LCD display is key to ensuring that the system is properly programmed. When programming, it is important to understand what functions the individual keys perform. The actual values key is used to look up specific values determined by the system. These values can include phase current data, metering data, and statistical data. The various arrow keys on the front panel are used to navigate the menus as well as to adjust parameters. The help key allows a user to display specific information regarding the specific parameter or menu they are accessing
