4. PARAMETER ENTRY
There are two methods of data entry: • Direct numerical number entry
• Tabular Input from a table menu.
If menu with direct numerical entry is selected use Up button to increment digit
value from 0-9. Use Dn button to move cursor to another digit position. When
desired value is entered use ENT button to accept (save in the EEPROM) new
value.
If menu with tabular entry is selected, the available menu options can be set
with the Up and Dn buttons and are accepted by pressing ENT button.
Note: During data entry the input values are checked for acceptability.
If data is not acceptable, it is rejected and a message is generated
indicating that the new data has not been accepted.
4.1 Submenu Program protection
After power has been turned on, programming parameters may only be changed
by turning program protection "OFF". There are two ways to turn off the
program protection:
1. If program protection code (PP-code) is on "0" (factory default), the
program protection is turned off by pressing ENTER key.
2. If a PP-code (1 to 255) other than "0" has been entered, this code must be
entered in order to turn the program protection "OFF".
The PP-code can be changed after the program protection has been turned off.
In order to protect device configuration parameters when changing the PP-code
the old PP-code must be entered after ENTER has been pressed.
Press ENTER key after entry of old PP-code.
