11. Select – setup wizard (1).
12. Select – Follow prompts to select out of service, (1 – safe mode).
13. Select – travel control, enter.
14. Select – psi value on the tag, enter.
15. Enter value 5 psi over max value on actuator tag, enter.
16. Select – Fischer enter/OK.
17. Select - 667 Type/model, enter.
18. Select – size on actuator tag enter.
19. Select – Yes if the heater has a volume booster or No if there is not a
volume booster, enter.
20. Select – send, 1/enter (configuration being sent).
21. Select – factory defaults yes, enter.
22. Run auto travel calibrate – OK, yes.
23. Cross over adjust, select – manual, enter.
24. Next (0 - 100% seeking high drive stop, then 100% - 0% seeking lo drive
stop, then 0 – 50% while adjusting output bias is occurring.
Note - During the bias setting portion, the 475 HART Communicator can
lockup in an endless loop. The only way out is to turn off the Milliamp
generator and start over. However, if there is a volume booster, unscrew the
screw another ½ turn or so when that screen comes up. If there is not a
volume booster, tweak the air a couple psi when that screen comes up. These
are the only two things that are proven to work to get past a lockup scenario.
25. Crossover adjustment source, select analog, 1/enter.
26. Adjust the current source until feedback arm is at crossover point (verify 12
mA on generator), enter. (12mA should put feedback arm at crossover point.
Feedback arm should be perpendicular to the actuator stem at cross over
point. Cross over point is when the pin in the feedback arm changes the
direction it is moving, usually mid travel 50%).
27. Seeking hi and lo drive stops
