Unlocked Code
To lock out the keypad, enter a numerical “password” between “1” and “9999” in
Keypad Lockout (CP-98), then press the “enter” key. This numerical password will flash
briefly on the screen, then the screen will display “LOC”. To unlock the keypad, enter
the same numerical password in Keypad Lockout (CP-98). The number will flash briefly
on the screen and then the screen will display “ULOC”. Control Parameters and
Monitor Parameters may be monitored during lockout, however, Control Parameters
can not be changed during lockout. The Clear/7 procedure will default Keypad Lockout
(CP-98) to “ULOC” (unlocked).
CAUTION:
Make certain that you record your password in the space provided on page 3-6, as your
password becomes transparent once you have entered it. If you forget your password,
you can use the Clear/7 procedure to revert back to the default “ULOC” (unlocked).
Please note, however, that the Clear/7 procedure will revert all of the Control
Parameters back to their original default values and you will lose any changes that you
have made to the Control Parameters. Therefore, make certain that you have recorded
all Control Parameter changes in the space provided in Appendix D before you use the
Clear/7 procedure. Refer to
Troubleshooting: Troubleshooting , page 4-11 for
instructions on the Clear/7 procedure. If you are uncertain how to enter a Control
Parameter, review the
Operations: Keypad section, page 3-3.
