IMPORTANT NOTES
– MOTOR PROTECTION: NII Control Box will now find the error and stop the motor by
itself to prevent overheating of the motor by overload.
Previous to this NII Control Box version, if Error E1 (Opening Safety) or E2 (Closing Safety) happened
continuously, the control box would register an E0 Error. Should E1 or E2 Error continue to happen and not
be resolved, an E0 Error would register 5 times in a row, at which point the Control Box would stop the motor.
An E0 Error would be shown on the LED display and the door would be in a failsafe stopped position.
With this New Control Box version, it will now stop the motor when an E1 or E2 Error happens 5 times in a
row. This is for added protect of the motor. Please note an E0 Error will no longer be applicable to this type of
overload situation.
IMPORTANT - To return back to normal operation:
1. To recycle the doors and reset Error protection (failsafe mode) switch mains power Off/On.
2. Please look to solve the cause of error. E1 and E2 Errors are mainly resolved by reducing the physical
resistance on the door. Note the door must run freely and easily.
Doors should be easy to push open by hand. Travel must be smooth and without noise.
Previous to this NII Control Box version, incase teaching distance is less than 150mm, an E0 Error would be
registered automatically, this would be added to other continuous E0 Errors and the motor would continue to
operate.
With this New Control Box version at the first E0 error, the door would assume in a failsafe stopped position.
Just in case rollers are not sitting on the rail correctly.
This motor protection features is always activated.
When the motor stops, green and red LED blinks at the same time
Buzzer for error notice can be used when switching Application Code setting
‘d0’ on.
