3.5.2 View the Existing Settings
All the existing setup data may be viewed on the LCD display by following a simple step-by-step dialog that may be
selected in the following languages: English (default), Spanish, French, German, Italian, Portuguese, Russian, Malay,
Mandarin, and Katakana.
1. Enter the “SETUP” mode as detailed in Section 2.1.1, Entering the Setup Mode.
2. Select the dialog language. Toggle “NO” to scan the language options. Select “YES” when the desired language
appears on the LCD.
3. Scan menu selections on LCD and select “YES” when “VIEW SETTINGS” appears.
4. Scan through the series of displays and answer “YES” or “NO” at the appropriate prompts. Each display shows the
state or value of the existing settings. See Figure 3.22.
NOTE: The “VIEW SETTINGS?” mode can be accessed without entering a password, but no changes to the settings can
be made in this mode.
3.5.3 Entering the Setup Mode
To customize the actuator, view settings, or view diagnostics, the user must enter the “SETUP” mode. A three-digit
password is required to customize the actuator. All actuators are supplied with the same default password (100). See
Sections 4.2 and 4.3, Password Entry and New Password for entering and changing password. Main power must be
applied to execute the setup procedure. It is recommended that the actuator be mounted to the valve before commis-
sioning the actuator.
Enter the “SETUP” mode as follows:
1. Place the red knob in the “STOP” position.
2. Within 10 seconds, place the black control knob in the “YES” position, then the “NO” position, then again in the
“YES” position (in quick succession—approximately one-two seconds).
3. The LCD will display “SETUP?” for 10 seconds. If no action is taken within the 10 seconds, the unit will return to
“STATUS OK.”
4. Using the black knob, answer “YES” or “NO” to the questions appearing on the LCD display.
NOTE: While in the “SETUP” mode, if there is a lapse of 15 minutes from last action, the unit will return to the
“SETUP?” display. Any changes that have been made will be stored.
