Chapter 2 Operation of Diagnostic
DC140 Monitor
Description: Monitors an analog component and checks its output.
• In the input function, each analog sensor is monitored periodically and the value is displayed.
• In the output function, the output to a component in a fixed/variable value is performed. However,
there is no component available for the output function.
• 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.)
• Two or more output values of an output component cannot be changed
simultaneously.
• Two or more items of input/output cannot be selected, executed, or stopped
simultaneously. (However, it is possible to stop all items simultaneously.)
• Even if any output value of an output component is changed, it is not reflected to
the NVM value.
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 and then the [DC140 Monitor Component Input]
screen in a lower level using the " → " key.
3. 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 [DC140 Monitor Component Input] screen in an
upper hierarchical level.
4. 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 4 and
5.)
5. 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 [DC140 Monitor Com-
ponent List] screen.)
• The information displayed as monitoring and output is chain-link No., Input/Output, input value
(monitored value)/output value (output level), in the order from left to right of the lower field.
• For any component in progress, "*" is marked at the right side of the input or output value.
