12. Positions 4,5,6 on SW2 are for the three North sensors (the silkscreen on
some dolly boards may be marked South). Use the same procedure (steps 6
through 9) for the North sensors adjusting R4, R5, R6 if necessary.
13. Use the same procedure (steps 6 through 9) for the West sensors (positions
7,8,9 of SW2) adjusting R7, R8, R9 if necessary.
14. After all of the sensors have been calibrated, set SW2 to position 0. The
Sensor assemblies will be raised and the RUN LED will turn on.
15. Pull off the Reset jumper JMP1 (located above rotary switch SW2). All of
the LEDs will turn on in rapid succession indicating that the microproces-
sor has been reset. Reinstall the jumper.
16. Switch the MCB controller to Remote and target the pedestal from the con-
troller (refer to the controller User Manual). After the pedestal targets suc-
cessfully, only the green OK LED on the Dolly Board should be on.
17. If the red ERR LED flashes after targeting, this indicates that one or more
sensors are incorrectly set. In normal operating mode, the “light meter”
LEDs are used as individual sensor indicators as marked on the board.
Therefore, one or more of these LEDs will be on to indicate which sen-
sor(s) need calibration. Repeat the adjustment for that particular sensor (or
sensors) and reset the microprocessor by removing and reinserting the
jumper JMP1.
Never use the Reset jumper JMP1 unless the calibration procedure has just
been completed. Otherwise, the automatic tracking thresholds will be
replaced by the prior starting thresholds which probably are no longer
optimum. If the jumper is accidentally reset, it is necessary to perform a
complete calibration as described above.
If you did not remove the covers earlier, replace the window in the North cover
and skip step 18.
18. Power down the pedestal and remove the jumper plug from the Stop switch
harness for each cover. Replace the East, West and North covers as
described earlier in this chapter.
