10.MAINTENANCE AND INSPECTIONS
Troubles Check points
Display does not come out. Is instrument correctly inserted in the case?
Are power terminals correctly connected?
Is power sufficiently supplied?
display
Memory error. If this still appears after putting power again , repair the unit.
display
A/D conversion error. If this still appears after putting power again, repair the unit.
display
Auto-tuning error. The display can be released by entering any key operation.
Be sure to check the following points, then try auto-tuning again.
Is a sensor correctly connected? Does process value indicate normal?
Is control output normal? Does temperature correctly rise(or fall)?
display
display
Unstable process value
Is the sensor normal? (Does another unit make the same error?)
Is the sensor correctly connected?
Is the type of sensor correctly setup?
Is correct value installed for the sensor correction value?
No noise mixing?
Unable to start Is the process value appropriate for any of the run steps after selecting PV Start?
Insufficient control Value setting of PID constant, control sensitivity and fuzzy strength all proper?
Temperature does
not increase(or decrease)
Is output terminal correctly connected?
Is control type correctly set up?
If any of the troubles still exists after following the above instruction, or for any other cases, contact our Sales
