Chapter 3 Initial Setup
3.1 Controller Setup
Now is a convenient time to make any required switch changes before
mounting the Controller in its desired location.
If the pressure display units of measure are correct (see Figure 3-1), and you
do not want to change the degas power timer from the factory setting of 10
minutes, skip to
Process Control Setup on page 32.
Figure 3-1 Units of Measure Label
If you want to change the units of measure, the display rate, or the degas
timer, you must remove the top cover of the Controller.
3.2 Top Cover Removal
1. With power OFF, remove any cables from Controller rear panel.
2. Observe antistatic precautions to avoid damaging static sensitive
components inside the chassis. Use a grounded, conductive work
surface. Do not handle integrated circuits (IC) devices more than
necessary, and only when wearing a high impedance ground strap.
(A high impedance helps protect human life in case of inadvertent
contact with high voltage.)
3. Remove the four Phillips head screws identified in Figure 3-2. If the
unit is equipped with a rear bracket, remove the Phillips head screw on
the bracket, and slide the bracket off.
