with the battery status indicator; ON with full charge and

OFF with the power removed.

Open collector: 30 V DC @ 100 mA

Saturation voltage: 1 V DC

■ Speed & Thrust

Acceleration or deceleration is not included in the speed.

Acceleration or deceleration respectively requires approx. 0

to 2 sec.;takes longer with faster speed.

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.
