What the Vibration Safety Switch Does

The
vibration safety switch
in
Figure 12: Vibration Switch, page 47
is an important safety fea-
ture. If properly adjusted, the switch will momentarily actuate as a result of repeated machine
movement caused by an out-of-balance condition.
below illustrates the effect of the
vi-
bration safety switch
actuation.

When the machine leaves Milnor
®
, the actuator arm is tie-wrapped to prevent damage (except on
30015, 30020, and 30022 models).
This tie wrap must be removed after the machine is set in-
to position but before the machine is operated.
Adjustment of this switch from the factory setting is not recommended; however, it should be
checked for proper functioning and adjusted if its proper setting is lost.
As shown in
Figure 12: Vibration Switch, page 47
, the unit consists of a
sensitive micro-switch
with an extended actuating arm supporting an eccentric weight. The weight may be adjusted by
moving it up and down on the arm and by rotating it on the arm. In addition, the
micro-switch
it-
self may be tilted from side to side.
The sensitivity of the switch increases as the eccentric weight is raised on the actuating arm
and decreases as the weight is lowered.
The unit should be adjusted so that the actuating arm will always reset by itself, this being accom-
plished by rotating either the switch or the weight to give just enough bias to cause the switch to
reset. Check the adjustment by moving the arm to the left then slowly releasing it. Make sure the
micro-switch clicks when the arm is
slowly
released, thus indicating that it has reset. In the re-
leased position, the arm should rest
lightly
but definitely against the stop on the
micro-switch
case that prevents any further arm movement to the left.
