CTV-PRB004-EN 27
Low-Voltage Starter Types
Environmental specification
• 32°F to 104°F (0°C to 40°C) operating ambient temperature.
• Altitude to 3,300 feet (1,000 m), amperage derate of 1 percent per every 300 feet above
3,300 feet.
• Humidity, 95 percent non-condensing.
Dimensions
Typical dimensions for the unit-mounted Adaptive Frequency Drive are shown in Figure 19 and
Figure 20. Always consult the submittal drawings for as-built dimensions.
Motor-AFD mutual protection
The chiller unit-controller capabilities allow the control/configuration interface to, and the retrieval/
display of AFD-related data. AFD standard design features controlled through theTracer
AdaptiView™ include:
• Current limited to 100 percent.
• Motor overload protection.
• Motor over-temperature protection.
• Phase loss, phase reversal, and phase imbalance protection.
• Undervoltage and overvoltage protection.
• Output speed reference via IPC3 communication bus from the chiller controller to the AFD.
Digital data display
The following points are digitally displayed at the chiller controller:
• Output speed in hertz
• Output speed in rpm
• Input frequency
• Input/output line voltage
• Input/output kW
• Input/output current
• Average output current in percent RLA
• Load-side power factor
• AFD transistor temperature
• Fault
