It is sometimes necessary to determine the level of the Cencon Lock with which you are working. This can be done
by entering a command via the keypad. The lock level will then be displayed on the LCD. Use the following
procedure:
1) Power the lock by turning the dial to the left (counter clockwise) until EC is displayed.
2) Enter the # 1 keypad command. Then the lock displays a string of characters on the LCD, displaying two
characters at a time. The best thing to do in analyzing the lock level is to write down the entire string and then
pick out the portions of it that are significant to you, or if you are experiencing a problem with the lock, report the
entire string to the Tech Support group.
6. Place the stopper to its original position and close door after operation.
7. Turn the dial a minimum of one complete rotation to the left (CCW) to extent the bolt.
<Note!>
After opening and closing any lock, you should always check to ensure that the lock
is physically relocked (i.e., bolt fully extended and locked in place) by turning the
dial to the right. If the bolt does not retract, you can be assured the lock is secured.
Helpful Hint:
At any point while entering the combination during an opening sequence, if you
notice that an incorrect number was pressed on the keypad, you may clear the
entire operation and start again by pressing the star ( * ) key. This allows you to
return to the EC prompt without getting a wrong try error (lightning bolt).
Caution - Lock Out (LCO):
When the combination is incorrectly entered, a lightning bolt error will flash on the
display (with no other numbers following it). To clear this error and start again,
press and hold the star ( * ) key. Even in Shelved Mode, it is important to avoid
getting 5 wrong combination attempts in a row without a successful opening in
between because the lock will be put into Lock-Out condition, displaying, "LCO."
Clearing the LCO condition in Shelved Mode requires waiting 5 minutes and then
entering the correct combination.
▶ Changing Shelved Mode Combination
For Cencon Locks with a code level of 71
Mode combination. You may change the default Factory Combination of 50-25-50
to a new combination to be used while the lock is still in Shelved Mode. Once you
have changed the combination for the first time, you may want to change the
combination again to a different Shelved Mode combination. You can even change
it back to the Factory combination of 50-25-50.
