INSTALLATION

Power consumption: Approx. 180 VA

Stand-by consumption: Approx. 18 VA

Operating temperature: -20 to +55°C (-4 to +131°F)

Charge: 0 to 55°C (32 to 131°F)

When the ambient temperature is less than 0°C (32°F), the

battery is not charged.

However, the ambient temperature reaches

within 0 to 55°C (32 to 131°F), the battery is automatically

charged.

Operating humidity: 30 to 85 %RH (non-condensing)

Vibration: Passed test condition below

•Fixed frequency endurance test

Frequency: at resonant frequency

Endurance: 30 min.

Direction: X, Y, Z

•Sweep endurance test

Frequency: 10 to 1000 Hz

Cycle: 20 cycles

Rate: 1 Oct./min.

Endurance: approx. 4 hr. 30 min.

Direction: X, Y, Z

Mounting position: All directions

Do not mount the actuator with its output stem on the

upside if the actuator is to be exposed to dripping water and

rain.

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 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 1/200 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 0.08 mA step (16 mA

/ 200 = 0.08 mA), the output stem rotates 0.45° (90° / 200

= 0.45°).

(Even for output stem 45°setting, resolution is 1/200 =

0.45°step)
