LOCAL PROGRAMMING
Local Adjustment
The local adjustment is available for FY500. The interface consists of a liquid crystal display and
magnetic tool. The positioner must be powered with at least 9.6V and 3.8 mA to operate the display.
Certain procedures require up to 20 mA of current.
Two jumpers are located on the main board to select the local adjustment (W1 jumper) and write
protection (W2 jumper).
Before beginning calibration ensure Local Adjustment jumper is in proper position (ON) on the main
board. The factory default is (ON) position.
The local adjustment holes are located below the identification plate.
1. To access the local adjustment, loosen the screw and turn the plate to the side.
2. The hole marked with (Z) allows to move forward through the programming tree to the next
menu item or increments the currently shown value in the digital display. Holding down the
magnetic tool causes the value to increase at a faster rate.
3. The hole marked with (S) allows to select or accept the value or parameter option currently
displayed.
WARNING
Do all changes and configurations very carefully since all modifications in the
parameters are recorded automatically and do not need user confirmation to save the
configuration.
