Keypad Lockout (CP-98) displays the present status of the keypad lockout. When the
keypad is locked, then “LOC” is displayed:

When the Keypad is unlocked, then “ULOC” is displayed:
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).
CP-79, Setpoint Lockout Mask, determines which setpoints are disabled when the
keypad is locked out. If CP-79 is set to "0", then none of the setpoints (CP-01 through
CP-04) are disabled. If CP-79 is set to "1", then all four of the setpoints are disabled. If
CP-79 is set to "2", then CP-02 and CP-04 are disabled while CP-01 and CP-03 remain
enabled.
