6.2.13 Clearing Option Unit Detection Results
The alarm A.E7 (option unit detection fail) occurs when turning ON the power for the first
time when the SGDH is used without option unit after the SGDH has been used with option
unit.
The following operation does not permanently reset the alarm A.E7. Restarting again after
performing the following operation will clear and reset the alarm A.E7. Then, the operation
of SGDH without option unit is enabled.
Because the parameter is set for the SGDH with an option unit, change the setting or initialize the
parameter value (Fn005 of auxiliary function mode) as required.
Using the Hand-held Digital Operator
1. Press the DSPL/SET Key to select the auxiliary function mode.
2. Select the parameter Fn014. Press the Left or Right Cursor Key to select the digit. Press
the Up or Down Cursor Key to change the number.
3. Press the DATA/ENTER Key. The following display will appear.
4. Press the DSPL/SET Key. The display will change as shown below and the option unit
detection result will be cleared.
5. Press the DATA/ENTER Key to return to the auxiliary function mode display.
This completes the clear of the option unit detection results.
