<div><p>The system enables service functions 50 through 70 when you select

manual mode and enter function 25 (service switch 1), then function 26 (service

<p>Functions 50 through 70 are now available.</p>
|
|
<p>You can disable the

|
service functions by selecting and entering either function 25 (service switch
|
|
1) or function 26 (service switch 2).</p>
|
|
<p>To disable functions 50 through
|
|
70, select function 25 and press Enter. Functions 50 through 70 are then no
|
|
longer available.</p>
|
|
<p><strong>Using Subfunctions</strong></p>
|
|
<p>To work with subfunctions,
|
|
do the following:</p>
|
|
<ol><li>Use the Increment or Decrement button to select the appropriate function
|
|
and press Enter. The function number appears with asterisks (**); for example,
|
|
<samp class="codeph">57**</samp>. The two asterisks indicate that subfunctions are available.</li>
|
|
<li>Press the Increment button. The first subfunction number appears; for
|
|
example, <samp class="codeph">5700</samp>.</li>
|
|
<li>As the subfunction number is displayed, press Enter. The system displays
|
|
data associated with the subfunction number.</li>
|
|
<li>Press the Increment button. The next subfunction number appears; for example,
|
|
<samp class="codeph">5701</samp>.</li>
|
|
<li>As the subfunction number is displayed, press Enter. The system displays
|
|
the data associated with the new subfunction number.</li>
|
|
<li>Repeat these steps to gather all the data that is associated with the
|
|
subfunction.</li>
|
|
<li>Use the Increment or Decrement button to return to the function display
|
|
with asterisks; for example <samp class="codeph">57**</samp>.</li>
|
|
<li>Press Enter to exit the subfunctions.</li>
|
|
</ol>

<p><strong>Function 51-System Processor Status</strong></p>
|
|
<p>This function

it. The failing processor must be replaced or the Repeat GARD function must

be cleared before that processor can be used again.</p>
