Figure 17. Spring Release Solenoid Armature Cap Adjustment
This adj us tment is to be pe
r
fo
rm
ed only after com­
pleting the spring release l atc h bi te ad j ustment
.
The purpose of this adjustment is to establish an arma­
ture gap of 3/16 (. 187) to 1 /4 (.250)
i
n ches
.
A suitable
feeler gage of optimum thickness, 7/32 (.218), should be
inserted in the armature gap. That is, the s
pa
ce between
the ground surfaces of the solenoid frame and ground "T"
s
hape
d
extensions of the solenoid plunger.
The
connecting
link
between t
h
e solenoid plunger and
spring release latch should be adjusted to maintain the
p
l unger in this position. The locking screw is released and
the adjusting cap shifted until the effective length of the
link supports the plunger within the indicated range.
MAINTENANCE AND TE:dTING
GENERAL
Thorough, periodic inspection Is important to satis­
factory operation. Inspection and maintenance frequency
depends on installation, site, weather and atmospheric
conditions, experience of operating personnel and special
operation requirements. Because of this, a well-planned
and
e
f f e c
t
ive maintenance program depends largely on
·28-
experience and practice.
ALWAYS INSPECT A BREAKER WHICH HAS IN·
TERRUPTED HEAVY FAULT CURRENT. All contacts,
arc runners, transfer stacks and arc chutes should be exam·
ined to determine if repair or replacement of parts is
required. Inspect for pieces of barrier stack and transfer
material in the cubicle as well
as
the circuit breaker.
