Installation & Adjustment Procedures
4.1.1 The switch is in the fully closed position when the centerline of the
male blade assembly is aligned with the centerline of the Female Blade
Assembly.
4.2 Set the adjustable arm to the preliminary setting on the Operating Mechanism
drawing, adjustment may be necessary to achieve proper operation.
4.3 Be sure that all stops have been loosened to prevent binding during test operations.
5 Final Adjustment:
5.1 Before making any adjustments always check that none of the pinned joints have
slipped. If slippage occurs, correct it and repeat the operation to verify that adjustment
is really needed.
5.2 Open the disconnect switch with the operator.
5.3 The switch is in the fully open position when both blades are approximately 90
o to the
switch base.
5.4 If the switch does not fully open before the operator reaches the fully open position,
the adjustable arm radius is too short. Close the switch, match-mark the adjustable
arm and the pipe clevis, and loosen the bolts on the adjustable arm and pipe clevis.
Lengthen the adjustable radius arm approximately ¼”. Allow the pipe clevis to
reposition itself the same ¼”. Refer to Figure 8 .
5.4.1 Test operate and readjust as necessary.
5.5 If the switch is fully open before the operator reaches the fully open position, the
adjustable arm radius is too long. Close the switch, match-mark the adjustable arm
and the pipe clevis, and loosen the bolts on the adjustable arm and pipe clevis.
Shorten the adjustable radius arm approximately ¼”. Allow the pipe clevis to
reposition itself the same ¼”. Refer to Figure 8 .
5.5.1 Test operate and readjust as necessary.
5.6 If the switch has too much toggle in either open or closed position, loosen the pipe
clevis and adjust to allow for an even toggle amount in both positions.
5.7 All poles of the fully adjusted disconnect switch should operate together, although a
slight variance between poles is acceptable. The primary objective is for all poles to
fully open and fully close. Minor adjustments of the inter-phase pipe clevises may be
necessary for pole coordination.
5.8 Setting Toggle:
5.8.1 Toggle is obtained when the switch is in the either fully open or fully
closed position and the connection point between the adjustable arm
and pipe clevis has gone past the centerline of the vertical operating
pipe. The operating linkage will snap past this point.
5.8.2 If possible the switch should go into toggle in both the open and closed
positions. This is not always possible, it is most important that the
switch goes into toggle in the closed position to help prevent the
disconnect switch from to opening during a fault condition.
