Keybd off / Keybd on 227 / 226
Purpose: to prohibit access to the keyboard when running a critical function. The Clear key will
turn the keyboard on if it has been turned off.
Remarks: the Keyboard off instruction is used to prevent accidental operator interference during
a critical function. The Keyboard on instruction restores access to the keyboard functions.
The Clear key is a fail-safe, in case the keyboard is disabled and accidentally not re-enabled.
Example: setpoint 1 is set to trip continuously (upper register = lower register) and activate
function 1. Function 1 turns off the keyboard and reactivates setpoint 1. This effectively
disables the Clear key from re-enabling the keyboard because the keyboard is turned off 60
times a second.
Keybd off disable the keyboard
Set pt on, 1 re-arm setpoint monitor 1
