If An Error Occurs Repeatedly - NF DP015S Instruction Manual

8.1.3 If An Error Occurs Repeatedly

If an error message repeatedly appears even though you removed the cause of the error, the error
may be resolved by restarting the power unit.
If the error still exists, the product or the power unit in the product may be faulty. Repair is needed
in this case. Contact the seller (NF Corporation or our agent) from whom you purchased the product.
Even though one of the power units is faulty, the product can be used by disconnecting the faulty
power unit and using the rest of them.
The following shows how to restart and disconnect the power unit in the case of an error.

4. If the error still exists, press the [PU-ON] soft-key again to open the power unit energization

faulty. Move the cursor to this power unit, then press the ENTER key. The check mark on this
power unit is removed, showing
mark as is. Select [OK].
6. The power unit energization setting is updated, and only the power units with the check mark
are restarted. When the error message window is displayed again, press the ENTER key.
7. Repeat the step 4 and later ones until errors are resolved. After the error is resolved, the product
can be continuously used using the power units with the check mark.
