Weight: Approx. 26.5 kg (58.42 lb) PERFORMANCE Insulation resistance: ≥ 100 MΩ with 500 V DC (signals to power supply voltage to sequential signals to metallic housing) Dielectric strength:
  • 2000 V AC @ 1 minute - signals or metallic housing* to power supply voltage - power supply voltage to sequential signals - signals or metallic housing* to sequential signals
  • 500 V AC @ 1 minute - signals to metallic housing * Short between signals and metallic housing FUNCTIONS
  • Error Detection When the position signal is deviated from the input signal but the output stem is stuck due to overload or certain malfunction, the PRP repeats starting the motor at the maximum torque for several times. If the stem is still stuck after that, the PRP outputs an alarm signal (LED turned ON) and stops power supply to the motor. In order to reset the PRP, apply several times 0% and 100% input signals in turn, or turn off and on the power supply.
  • Abnormal Temperature Increase Protection When the incorporated temperature sensor detects an abnormal temperature increase in the motor, the alarm LED blinks (repeating 0.5-sec. ON – 0.5-sec. OFF) and the power supply to the final control element motor is stopped until the temperature decreases to an acceptable level. The PRP is designed to resume automatically power supply to the motor. It takes longer to resume normal operation when ambient temperature is higher.
  • Restart Limiting Timer This unit is equipped with a timer protecting the motor from overheating. The timer prevents the motor from restarting for a certain interval once the motor has been stopped within deadband. When the high temperature protection is activated in a high temperature ambient, adjust the timer to a longer interval.
  • Motor Preheat Function When this unit detects a temperature lower than 0°C or 32°F (approximate) on the surface of its motor, this unit supplies current to the motor in order to warm up and maintain its surface temperature at 5°C or 41°F (approximate). Maintain the power-supply voltage ON when this unit is used in the ambient temperature below 0°C or 32°F.
  • Resolution The ratio that the stem of the unit rotates according to input signal. E.g. Resolution is 1/300 for the specification that input signal is 4 to 20 mA, output stem 90°, direct or reverse action. As the span of input signal is 16 mA (20 – 4 = 16 mA), when input signal is changed by 0.053 mA step (16 mA / 300 = 0.053 mA), the output stem rotates 0.3° (90°/ 300 = 0.3°). (Even for output stem 60°setting, resolution is 1/300 = 0.3°step) It is not true that input signal = output signal. (Not input signal 4.00 mA DC = output signal 4.00 mA DC, there is difference around ±0.012 mA DC.)
