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
