7.
Wire test light as shown using a neon bulb. Adjust each contact position by
bending
N
o support strap until light just blinks out when center strap goes from
N
'c
to
N
' o strap. Obtain smallest possible center strap motion with light out.
8. Remove jumpers and test light leads and recheck for no strap pressure on
cam lobes with unit at zero reading. To check for this condition have machine idle
under power and trip one side of each unit at a time. If there is an appreciable
movement of the center strap on the side of the unit where the contacts are not
transferring, it is a sign of strap pressure on cam lobes at zero reading. When this
check indicates an incorrect adjustment, the contacts for that position should be
adjusted individually on the machine by bending the
N
'C
support strap until
contact pressure is relieved with zero reading in both sides.
