FUNCTIONS
INPUT SIGNAL SPECIFICATIONS
■ DC Current: Input resistor incorporated (not removable)
■ Forced Operation: External contact signal input terminals
provided for compulsory opening or closing operation
Rating: 5 V DC @ 2.5 mA
• 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.
OUTPUT SIGNAL SPECIFICATIONS
■ Position Signal: 4 – 20 mA DC
Load resistance: ≤ 300 Ω
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.
• Sequential Control Signal: "Full-open", "full-closed" and
"alarm"
Open collector: 30 V DC @ 100 mA max.
Saturation voltage: 1 V DC
INSTALLATION
Power consumption: 180 VA
Stand-by consumption: 30 VA
Operating temperature: -20 to +55°C (-4 to +131°F)
Operating humidity: 30 to 85 %RH (non-condensing)
Vibration: Passed test condition below
•Fixed frequency endurance test
• 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.
Acceleration: 2 G (19.6 m/s )
2
Frequency: at resonant frequency
Endurance: 30 min.
When the high temperature protection is activated in a high
temperature ambient, adjust the timer to a longer interval.
• Motor Preheat Function
Direction: X, Y, Z
•Sweep endurance test
Acceleration: 2 G (19.6 m/s
Frequency: 10 to 1000 Hz
Cycle: 20 cycles

)
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).
Rate: 1 oct./min.
Endurance: approx. 4 hr. 30 min.
Direction: X, Y, Z
Maintain the power-supply voltage ON when this unit is
used in the ambient temperature below 0°C or 32°F.
• Resolution
Mounting position: All directions
Prevent water from accumulating around the output stem.
Weight: Approx. 26.5 kg (58.42 lb)
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°).
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

0.3°step)
