IMPORTANT

If you remove the vent/drain plugs when 

disassembling EJ

130

 and EJ

440

 

transmitters, install the plugs again before 

reassembling the cover flanges with the capsule 

assmbly. 

8.4.4  Replacing the Process Connector 

Gaskets

This subsection describes process connector 

gasket replacement. (See figure 8.5.)

(a)  Loosen the two bolts, and remove the process 

connectors.

(b)  Replace the process connector gaskets.

(c)  Remount the process connectors. Tighten the 

bolts securely and uniformly to a torque shown 

below, and verify that there are no pressure 

leaks.

8.5  Troubleshooting

If any abnormality appears in the measured values, 

use the troubleshooting flow chart below to isolate 

and remedy the problem. Since some problems 

have complex causes, these flow charts may 

not identify all. If you have difficulty isolating or 

correcting a problem, contact Yokogawa service 

personnel.

8.5.1  Basic Troubleshooting

First determine whether the process variable 

is actually abnormal or a problem exists in the 

measurement system. 
If the problem is in the measurement system, 

isolate the problem and decide what corrective 

action to take.
This transmitter is equipped with a self-diagnostic 

function which will be useful in troubleshooting, 

and the transmitter equipped with an integral 

indicator will show an alarm code as a result of self-

diagnosis.  

See subsection 8.5.3 for the list of alarms.
