Notes on installing the cover and adjusting the cover open
switch
1. Use a 0.050-inch hex driver to insert a 4-40 set flat socket screw (5) into the
cover assembly, at its correct location. Refer to the illustration. Before inserting
the set screw, apply Loctite 425 to the set screw threads. Insert the screw until
only two or three threads are visible.
2. Snap the cover assembly into the hinges. Close the cover.
3. The switch is normally wired open in series with the cover lever switch that is
also normally open. Connect an ohmmeter across the black and white wires,
Positions 3 and 4 on the six-pin wire harness connector (J6). The cover lever
switch must be closed in order for the ohmmeter to register the closing of the
cover open switch. As you turn the set screw counterclockwise, the switch will
actuate and the meter reading will switch from open circuit to a very small
resistance. Turn the set screw an additional 1/2 turn (180º).
Note: Before the adjustment, you must remove the shrink tubing from
the cover open switch lever. This will provide access to the hole
in the lever through which the hex driver can get at the set screw.
Replace the shrink tubing after adjusting the set screw.
