*Alarm 86, illegal configuration, will result if value is not inputted
correctly.
†For size 038, enter “034” for SIZE.
For size 048, enter “044” for SIZE.
For unit size 078, enter “074” for SIZE.
For unit size 088, enter “084” for SIZE.
For unit size 104, enter “‘108” for SIZE.
NOTES:
1. Calibration of the pressure transducers is not required unless prob-
lems with the transducers occur or the standard PSIO is replaced. To
calibrate pressure transducers:
a. Disconnect from system.
b. Hang in the atmosphere.
c. Read pressure. Pressures before calibration must be in the
range of ±3 psig (atmosphere).
d. Press .
e. Reattach to system.
2. Upon completion of the factory/field configuration step, move to the
DTRS (Data Reset) subfunction. Press , and all revised
inputs will be loaded. This procedure takes approximately 40 sec-
onds. The display returns to the default rotating display.
