6. To calibrate the 4-20mA output range, first change the following

jumpers with power ON, then calibrate:

• E6-E9 to the current position (left)

• E10, E14, E13, E17 to the current position (top)

E17

E13

E14

E10

Step Enter Command Code (BTW 2): and Read in BTR:

1 0080H word 4 = 0FFF

2 8080H word 5 = 0FFF

7. To verify 4-20mA range, enter command codes 0400H and 8400H.

Then apply these codes for current:

Step Apply Code for Current (BTW 3-6): and Read Verification Code (BTR 10-13):

1 000H (4mA) 000H

2 0800H (12mA) 0800H

3 FFFH (20mA) FFFH

8. To store the calibration data in EEPROM, follow these steps:

Step Enter this Command Code (BTW 2):

1 0800H

2 8800H

3 0000H

ATTENTION: To avoid possible injury or machine damage

when you return the QI module for service, make sure you

reset the jumpers to the original pre-calibration settings.

9. If there is no error in the BTR status byte, you completed the procedure.

Reset jumpers, re-assemble the module, and return it for service.
