• Observe the current regulations on accident prevention
and safety for electrical devices during operation and
mainte-nance of the device!
• Before interfering with the system, always switch off the
voltage!
• Note that in systems under pressure, piping and valves
may not be loosened!
• Take suitable precautions to prevent inadvertent

A temperature sensor (RTD) connected via a temperature transmitter is adjusted to give an output of 4ma at 60 deg and 20 ma at 600 deg. This output (4-20ma) from the transmitter is connected to an IGBT-inverter to control a high speed (-12,000 to +12,000 RPM) DC motor. And in the inverter it is programmed as, for 4ma the motor speed will be -3,000 RPM and for 20ma the motor speed will be +10,000 RPM. The question is : If the motor speed is +5,500 (RPM), what will be the temperature? (-sign indicates that the motion is in reverse direction).
