Installation & Adjustment Procedures
Final Switch Adjustments (Tuning):
1. The operating mechanism is intended to fully open and fully close the disconnect switch
by rotating the vertical operating pipe approximately 180
o
using an operator (manual or
electrical). The interphase pipe controls the individual operation of each switch pole, using
a push/pull control. The reach rod translates the motion of the vertical operating pipe to
the interphase linkage. The adjustable arm controls the total amount of switch operation
available.
For easiest adjustment start with the reach rod connected to the drive phase and the
interphase pipe disconnected from the other two phases. Once the drive phase is properly
adjusted, connect the interphase pipe and continue tuning the other two phases, one at a
time.
2. Switch Operating Devices:
2.1 Worm gear operator (HOGO – High Output Geared Operator) (Optional)
2.1.1. The operator handle is factory set to rotate clockwise to open the switch.
2.1.2. The weight of the vertical operating pipe should be supported by pipe collar
) by maintaining the 1/4 - 3/8” gap (
2.1.3. When the switch is properly adjusted the operator handle should hang freely in
both the open and closed positions to permit the use of a customer supplied
padlock. Refer to
2.1.4.
Caution:
Be aware that there is an adjustable stop on the operator.
Do not
over
operate as damage will occur to the operator.
