TROUBLESHOOTING TABLE

 

SYMPTOM

 

SOLUTION

 

6. Continued

 

4.  If the Temperature Compensation Option is 

installed, verify correct temperature input signal. 
Verify that the temperature input is connected 
correctly.

 

5. Contact 

Factory

 

7.  Incorrect Temperature Reading

 

1.  Verify Temperature Transmitter specifications 

match with MicroTrans

EQ

 ID Label 

(Current/Voltage, Temperature Range)

 

2.  Verify Temperature Transmitter is connected 

correctly to the MicroTrans

EQ

 (see Section 3.2).

 

3.  Verify Temperature Transmitter signal at the 

MicroTrans

EQ

 connector J2 is correct. 

 

4. Contact 

Factory

 

8.  No Output signal or Incorrect Output 

signal. Display is reading correct 
value.

 

1.  Verify Process Output S2 & S4 switches are in the 

correct position for the application (see Section 4.1 
and the figure in Section 3.1.

 

2.  Disconnect Output signal wires and verify output 

signal at MicroTrans

EQ

 connector J2 is correct.

 

3.  Verify correct Operating Range (see Section 5.2)

 

4.  Perform Output Cal (see Section 9.7)

 

5. Contact 

Factory

 

9.  Incorrect Process Output Values after 

changing Area Factor, Altitude, or 
Temperature Value.  Display readings 
are correct.

 

1.  Re-Enter Operating Range Value in Field Menu 

(see Section 5.2) 

2. Contact 

Factory

 

10.  Unstable Display and Process Output 

at very low flow. 

 

1.  Increase Display and Process Filter

 

2.  Decrease Lockdown Value

 

3.  Increase Lockdown Delay Value

 

4. Contact 

Factory

 

11.  “AZ Error” text on display 

1.  Turn Power Switch S3 Off and On to reset the

 

AutoZero valve
