1 Set the shutter arm's position along the shaft
to distance "A" (using a feeler gauge) or
distance "B" (using a calliper gauge) and
tighten one of the set screws just enough to
hold the adjustment.
2 Plug an extension
connection PCB and the head cable or PCB
output.
3 Apply power and cancel the pan/tilt reset by
pressing the "Menu" and "Enter" keys on the
control panel. Allow the reset to complete and
then navigate the control menu to UTIL / AdJ /
HEAd / bEAM / AdJ. Press the drive lever
against the inside stop and tighten the set
screws.
4 Check the adjustment with the "IN" and "OUT"
commands: when selected, the drive arm
should be about 0.5 mm (0.02 in.) from the
inside and outside stops, respectively. (If the motor turns backwards, the extension
cable is reversed at one end.)
