2. Installation Requirements
– ENSURE:
All components have been installed correctly in accordance with the installation manual and all
wiring has been connected referring to EDM NII Series wiring drawings. (except main cover and
activator on the main cover)
The door should be easily moved open and closed by hand without abnormal sounds.
Confirm that wires and cables do not touch moving components such as belt or hanger roller
assembly.
Run / Program mode se
lecting switch should be set in ‘Run’ position to execute the teaching
operation.
3. Executing Self learning cycle (TEACHING)
Self learning cycle is executed after installation by turning the mains power switch ON for the first
time. The door will close (*1) to the full closed position, then open automatically (*2) at slow speed.
When the door has reached to the full open position, the first stage of the teaching cycle is complete
and the door will start to close at normal speed.
Activate the sensor and check the door will open smoothly. Here, the breaking position is located at
the center of doorway is automatically calculated. After a few cycles, the operator will optimize the
braking point taking into consideration operating speed, breaking force and door weight.
Teaching data such as the door stroke and braking position will be stored within the control unit,
even if the mains power is OFF.
Once the mains power is turned ON, the stored data will be reloaded when the door reaches the
fully closed or open end position.
Motor torque value during teaching mode will be the same as factory default values. Or if
re-teaching, will be the same as basic setting code values held within the memory. For max torque
when teaching switch application code ‘dL’ OFF.
(*1) If the door does not close, check Red LED (sensor indicator) is ON. If Red LED is ON, this means
there is an activation signal being received. Once reaching the full open position, after the sensor
signal is off and the hold open time is complete, the door will close and return to full closed position.
(*2) If teaching stroke
setting (Basic Setting Code ‘b’) is changed from factory default setting. The
teaching function will not be automatic. It is required to be activated by a sensor or test button, after
door has reached full closed position. The door will open at programmed teaching speed. On
Activation of sensor before fully closed, the door will re-open at slow speed.
