5-6.2 OPERATIONS COUNTER
All HK-VSR Vacuum Motor Starter Replacement Units are equipped
with a mechanical operations counter (Figures
3-3
). As the starter
opens, the counter advances the reading by one.
5-7 LEVERING DEVICE
The purpose of the levering device is to move the starter between
the Test and Connected positions. The levering-in mechanism is
located on the starter truck on the 5HK-VSR.
THIS VACUUM STARTER REPLACEMENT IS NOT DESIGNED
TO OPERATE A SEPARATE EXTERNAL AUXILIARY SWITCH
(MOC SWITCH).

structure. 5HK-VSR starters utilize a levering-in interlock design
that is very similar to the design used on HK breakers.
5-6 MISCELLANEOUS ITEMS
5-6.1 GROUND CONTACT
The ground contact is an assembly of spring loaded fingers for all
5HK-VSR Vacuum Motor Starter Replacement designs providing a
disconnectable means for grounding the starter chassis, after it
has been inserted into a switchgear cell (Figure
5-7
). The ground
contact is located on the underside of the chassis next to the
secondary contact block. An extension of the switchgear ground
bus is secured to the cell floor in such a position to engage the
ground contact automatically, when the starter is pushed into the
Test position. It remains engaged in all positions from Test to and
including Connect.
