Chapter 2 Operation of Diagnostic
DC330 Components
Description: Enables an input/output checking for each component.
• A maximum of 8 items of input and output can be operated simultaneously.
• If any components which are prohibited from being output simultaneously are
selected, the component input first is turned off and the other component input
next is turned on. (Priority is given to the component input later.)
• If there are two or more components which are prohibited from being output
simultaneously, turn off all the applicable components and then turn on the
component input later.
Procedure:
1. Enter the Diag (C/E) mode, and select [Diag. Menu Fault Diag.] in the same hierarchical level using
the " ↓ " key.
2. Select the [Fault Diag. DC140 Monitor] screen in a lower level using the " → " key.
3. Select the [Fault Diag. DC330 Components] screen using the " ↓ " key.
4. Select the [DC330 Components Component Input] screen in a lower level using the " → " key.
5. Show the chain-link No. input screen using the " → " key again.
• To set the chain-link No., move the cursor using the " ← " or "→ " key and change a numerical
value using the " ↑ " or " ↓ " key.
When the cursor is positioned at the left end of the chain-link No., pressing the " ←
" key allows you to return to the [DC330 Components Component Input] screen in an
upper hierarchical level.
6. The chain-link No. is fixed by pressing the "FEED / SELECT" key. Then, "*" is marked at the right
end of the changed value. (A maximum of 8 items can be registered by repeating the steps 6 and
7.)
7. When the chain-link No. has been fixed, check the number of registered items using the "FEED /
SELECT" key again, and execute the component.
• When 8 items are registered, the deletion confirmation screen [Max Over.Must Del If OK press
SEL] is shown for restricting the number of registered items. Then, complete the registration
using the "FEED / SELECT" key.
• If there is any applicable chain-link No. and monitoring is started, you are brought to the
monitoring list screen. (The monitoring list screen is a DC menu under the [DC330 Components
Component List] screen.)
• The information displayed as I/O is a chain-link No., input/output, counter (shows the
accumulated number of changes of High/Low only at input), status indication (Input: "High/Low"
indication at a connector level; Output: "On/Off" indication), in the order from left to right of the
lower field.
• For any component in progress, "*" is marked at the right side of the status indication.
8. If there is no applicable chain-link No., the NG screen is displayed as shown below. In this case,
press the "FEED / SELECT" key to return to the chain-link No. input screen.
