Pressing the RESET key resets the coast counter to zero, returns the
display to the total count display, and returns the TMD to Run mode
(NORMAL LED is lit).
Password protection is used to restrict access to the setup and calibration
settings. The SW1 DIP Switch on the display board enables or disables
the password protection software (refer to Section “DIP Switch
Settings”). If the TMD is password protected, settings may be viewed
but not changed.
If the switch is set to enable password but no password has been defined,
the display will show PSWD N when you SCROLL down from the Run
screen. If you do not define a password, protection is not enabled and
the system will go to the calibration screens when you SCROLL down
again.
Follow this procedure to define a password. The procedure begins at the
PSWD N display.
1. Press a value key then press ENTER.
The display changes from PSWD N to PSWD Y indicating that you
want password protection. The Y will be flashing.
2. Press ENTER
3. Press the SCROLL down key.
The display changes to PSWD=. The counter shows 000 and the
first digit will be flashing.
4. Press the VALUE keys to scroll through the range 0–9.
5. When the digit you want is showing, press ENTER.
The next digit in the counter will be flashing.
6. Repeat the process of scrolling the counter and entering the digit
until your password is defined.
The range for each of the three digits in the password is 0–9, so your
password can be from 000 to 999.
7. To activate the password, put the TMD into Run mode and wait at
the Run screen for 30 seconds.
If password protection is active, the display will show PSWD= when
you SCROLL down from the Run screen. If you want to make any
changes to calibration settings, you must enter the password. The
display changes to PSWD Y and you can proceed to the calibration
