[5] Inspection of numeric display
After closing the power source, the 4-digit display unit displays the following contents.
Power ON

6.2 Maintenance inspection
The eqipment does not contain any consumable parts which may run down in a short time.
•
The standard guidline replacement period of smoothin capacitor is 5 to 10 years.
Since the standard replacement period may vary, depending upon the magnitude of output current,
ambinient temperature or operation rate, place an order or smoothing capacitor from the Service Cen-
ter of Mitsubishi Electric as required.
The EEPROM ( used for storage of setting data ) is serviceable for 100,000 re-writing, and the power
•
source ON/OFF operation is limited to 100,000 times or less.
For periodical inspection, check for the following items;
•
Check that the panel temperatute is not unusually increased due to heating element, direct sun-
•
shine, etc.
Check that the powder dust or cuductive dust does not enter the panel.
•
Check that the wiring terminal is not loosened, and that there is not any other failure.

When the DIP SW4 to SW10 are all turned on,

the contents shown left is displayed for 2 sec-
onds. (It is invalid to change the switch ON/
OFF after turn on the power source.)
When the DIP SW4 to SW10 are set to 0.2 to

4.0A, the contents shown left is displayed for 2
seconds. (It is invalid to change the switch ON/
OFF after the closing the power source.)
The error is displayed exept when the DIP SW4

to SW10 are set to the other than above.
In such a case, turn on the power source after
setting the DIP SW4 to SW10 correctly.
< Display of input signal level >
When the DIP SW2 is turon on, the the input
•
signal level is set to 0 to 5V (SW3=ON), or set
to 0 to 8V ( SW3=OFF ), by which the current
setting value is displayed for 2 seconds as
shown left.
When the DIP SW2 is turned off and SW3 is
•
turned on, the input signal level is set by key
operation.
In this case, the current setting value is displayed
for 2 seconds as shown left.
When the DIP SW2 and SW3 are turned off, the
mode is set to the built-in variable resistor.
