NOTE: If the Interface Module displays only one zero (i.e. “0”), then the program lockout
connector is not jumpered. For wiring instructions, see Section 3.2: Wiring.
3. Enter either the program or supervisory mode access code. The default
program mode access code is 2100. Select the enter key.
The monitor is now in either program mode or supervisory mode. The
program mode LED is turned on.
NOTE: The Interface Module can be taken out of program or supervisory mode at any time
by entering an invalid access code in the Program Mode Access function. Further, the
access code (2100) is provided initially. However, this code can be changed through the
use of the New Access Code function. For security reasons, this function can only be
implemented when the monitor is in supervisory mode. For more information on New
Access Code, contact the factory.
Program Mode Time-Out (11)
The Program Mode Time-out function is used to change the duration of time the monitor will
stay in program mode once the Program Mode Access function is entered (see Program Mode
Access). If a key is not pressed within the time programmed in this function, the monitor will
drop out of program mode. Every time a key is pressed, the timer will restart. The default for
this function is 120 seconds. This value can range from 10 to 1000 seconds. To change the
program mode time-out value, perform the following steps:
1. Select the function key.
The monitor displays “F-----”
2. Select function number 11. Select the enter key.
The monitor displays the function’s current value.
3. Enter the new time-out value. Select the enter key.
NOTE: The Program Mode Time-Out function serves two purposes. The fi rst is that when the
monitor is in program mode and a key is not pressed within the time-out delay, this
function will take the monitor out of program mode. The second purpose is that when
the monitor is displaying something other than the machine position, and is or is not
in program mode, and a key is not pressed within the time-out delay, this function will
force the monitor to display the current machine position.
