Installation & Adjustment Procedures
Operating Mechanism Adjustment (Three Phase
Installation)
1. Position all Grounding Switch poles closed and all Disconnect Switch poles open.
2. The Adjustable Arm setting on the Op-Mech Drawing is a calculated dimension.
Adjust as required for exact setting.
3. The Adjustable Arm radius is
too short
if the Grounding Switch does not open
fully (Blade in horizontal position). To correct:
•
Check for slippage
•
Return the switch to the closed position.
•
Operate the switch toward the open position to remove pressure on the
linkage.
•
Loosen Adjustable Arm and Clevis Bolts -
Figure 10: Top View of Adjustable Arm Assembly
•
Lengthen the Adjustable Arm radius approximately ¼”. Shorten the pipe to
allow the Clevis to reposition itself the same distance.
•
Re-tighten the Adjustable Arm and Clevis Clamping Bolts.
•
Test Operate. Re-adjust as necessary.
4. The Adjustable Arm radius is
too long
if the Grounding Switch reaches the fully
open position (Blade in horizontal position) before the switch operator reaches
the open position. To correct:
•
Check for slippage
•
Return the switch to the closed position.
•
Operate the switch toward the open position to remove pressure on the
linkage.
•
Loosen Adjustable Arm and Clevis Bolts -
•
Shorten the Adjustable Arm radius approximately ¼”. Lengthen the pipe to
allow the Clevis to reposition itself the same distance.
