Lockout & Error History
The Vmax 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 17-5(a).
2. Press the “OK” button to display the most recent error, and the time between it and the preceding error;
see Figure 17-5(b).
3. Press the UP button to display the next most recent error, and time between it and the preceding error; see
Figure 17-5(b). 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 17-5(c).
