Rockwell Automation 1771-QDC PLASTIC MOLD.MODULE - Manual (Page 292)

6–8 Calibration Instructions
Publication 1771-6.5.88 – July 1997
After calibrating inputs, calibrate outputs as follows:
•
change jumpers as required (with power ON)
•
enter command codes in BTW word 2
•
enter voltage codes in BTW words 3, 4, 5, and 6
•
read verification codes in BTR words 10, 11, 12, and 13
Important: Do not remove module from the I/O chassis or turn off
power. Loss of power voids the procedure and requires
that you repeat the entire calibration procedure starting
with inputs.
1. With the power remaining ON, connect the output wiring arm.
2. To calibrate the –10 to +10V dc output range, follow these steps:
Step Enter Command Code (BTW 2): and Read in BTR:
1 0020H word 4 = 000F
2 8020H word 5 = 000F
3. To verify –10 to +10V range, enter command codes 0100H and 8100H.
Then enter voltage codes:
Step Enter Voltage Code (BTW 3-6): and Read Verification Code (BTR 10-13):
1 000H (for 0 volts) 000H
2 0400H (for +5 volts) 0800H
3 7FFH (for +10 volts) FFFH
4. To calibrate the 0 to +10V dc range, first change these jumpers with
power ON: E11, E12, E15, E16 to the 0 to +10V dc position (bottom)
E16
E11
E15
E12
Step Enter Command Code (BTW 2): and Read in BTR:
1 0040H word 4 = 00FF
2 8040H word 5 = 00FF
5. To verify 0 to +10V range, enter command codes 0400H and 8400H.
Then enter voltage codes:
Step Enter Voltage Code (BTW 3-6): and Read Verification Code (BTR 10-13):
1 000H (for 0 volts) 000H
2 0800H (for +5 volts) 0800H
3 FFFH (for +10 volts) FFFH
