What to do if there is a current signal fault in metso automation kajaaniMCAi?
If the MCAi reading and the current signal value do not match, ensure that the current signal cables are correctly connected before replacing the electronics of your Metso Automation Measuring Instruments.
How to fix a leak in the microwave antenna of Metso Automation Measuring Instruments?
If you observe a slow drift of the measurement signal in one direction for your Metso Automation Measuring Instruments, it indicates a leak. Replace the antenna along with its cable to resolve this issue.
What to do if there is antenna contamination in metso automation kajaaniMCAi?
If the antenna of your Metso Automation Measuring Instruments gets cleaned periodically, especially when the wood species changes, the upwards drift caused by contamination may disappear.
How to resolve issues related to chemicals content in metso automation kajaaniMCAi Measuring Instruments?
A substantial increase in the chemicals content may attenuate the signal level below the low limit set for the self-diagnostics. The signal level can be increased by performing a new start-up (section 6.A) at the new, higher signal level. Large variations in the chemicals content may also cause error in the measurement, so you can use chemicals compensation to eliminate the error; see instructions in section 9.B or 12.C.1 (HART communicator).
What to do if material is attached to the fork-type sensor of metso automation kajaaniMCAi Measuring Instruments?
If you find string or other material attached to the fork-type sensor of your Metso Automation Measuring Instruments, install a deflector plate to divert these materials past the sensor. This kind of problem appears either as a drift in the measurement or as a rapid level change.
Why is there a temperature measurement error in metso automation kajaaniMCAi?
If the Pt-100 sensor connector is disconnected, defective Pt-100 sensor cable, defective Pt-100 sensor, or fault in Electronics Unit can cause temperature measurement error. First make sure that the Pt-100 sensor connector is securely connected to the Field Connection Board of your Metso Automation Measuring Instruments.
What causes low signal due to temperature in Metso Automation Measuring Instruments?
A substantial drop in process temperature may attenuate the signal level below the low limit set for the self-diagnostics. The signal level can be increased by performing a new start-up (section 6.A) at the new, higher signal level.
What causes a reference channel fault in metso automation kajaaniMCAi Measuring Instruments?
This fault in Metso Automation Measuring Instruments is always caused by the Electronics Unit. Replace the Electronics Unit and perform a new start-up as instructed in section 6.A or in chapter 12. (HART communicator).
