Lockout & Error History
The Tx controller stores in its memory the 16 most recent Lockouts (Loc) and Blocking Errors (Err); these errors
can be accessed from the Installer Menu via settings 2-34 (Lockout History) and 2-35 (Blocking Error History).
The History submenus indicate which Lockout or Error occurred, and the time interval between each occurrence.
Navigate the Lockout and Error History submenus as follows:
1. Navigate to Installer Menu setting 2-34 (Lockout History) or 2-35 (Blocking Error History). From this
screen the display indicates how long ago the most recent error occurred; see Figure 17-5a.
2. Press the "OK" button to display the most recent error, and the time between it and the preceding error;
see Figure 17-5b.
3. Press the UP button to display the next most recent error, and time between it and the preceding error; see
Figure 17-5b. When you have reached the end of the recorded errors, the display will indicate "End 0".
To exit the History submenu, press the "OK" button; see Figure 17-5c.
