TERMINOLOGY • 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 PSN repeats starting the motor at the maximum torque for several items. If the stem is still stuck after that, the PSN outputs an alarm signal (LED turned ON) and stops power supply to the motor. - In order to reset the PSN, 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 motor is stopped until the temperature decreases to an acceptable level. This electronic actuator 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. • Sealing Spring The PSN is incorporated with springs to maintain sealing pressure when the valve is fully closed. Choose an appropriate sealing pressure. These springs provide the same pressure at both fully closed and fully open positions. Do not apply a greater pressure to the spring than specified.
