4.2 Password Entry
Default = 100
Unauthorized entry to the “CHANGE SETTINGS?” mode is prevented by a password protection feature. If password
protection is not required, the password may be set to “000.” The user will not be prompted to enter a password when
the password is set to “000.”
1. Enter the password digit by digit. The password is a three-digit number, ranging from 000-999. The factory default
is 100.
2. If the wrong password is entered, re-enter the correct one. After three attempts to enter the correct password, a
recovery screen will appear. The screen will display a serial number that can be used for password recovery. A
password recovery service is available. Contact Limitorque service coordinator at (434) 528-4400.

4.3 New Password
The password may be changed from the default of 100 to a customer-selected value as indicated in Figure 4.5.
The new password becomes effective as soon as the operator answers “YES” to the “RECORD PASSWORD?” display.
NOTE: Take care to record the new password in a secure location to ensure its retrieval in the future, yet prevent
unauthorized access to the actuator “SETUP” routine.
If password protection is not required, the password may be set to “000.” The user will not be prompted to enter a
password when the password is set to “000.”
