CHECK FOR WELDED CONTACTS IN
OVERLOAD RELAY
This feature permits the maintenan e
man to he k for welded relay onta ts
by simply depressing the white operator
lo ated at the top of the overload relay
onta t housing. When the relay is in the
reset ondition, an audible “ li k” will be
heard when the operator is depressed,
indi ating that the onta ts are
operating normally. A ontinuity he k
an also be made by dis onne ting the
ontrol wiring from the terminals of the
relay and pla ing a bell set or a
resistan e-measuring instrument in the
ir uit. Conne ting either of these a ross
the relay terminals will indi ate the relay
onta t is losed until the onta t- he k
operator is depressed, opening the
ir uit.
The ex lusive manual onta t operation
he k gives positive assuran e that
onta ts have not welded due to short
ir uits in the ontrol wiring.
300/400-Line starters and onta tors require
virtually no orre tive maintenan e. Preventive
maintenan e will assure many years of
dependable on-line servi e.
1. Always remove power from devi e before
performing any maintenan e.
2. Keep magnet mating surfa es free of
a umulated dirt or dust.
3. DO NOT OIL OR GREASE the magnet mating
surfa es.
4. Conta ts are arefully designed for maximum
life. They need only
be repla ed when nearly all the
silver tip is gone and the onta t tip support is ex
posed. DO NOT FILE the onta ts. Filing or
otherwise dressing the onta ts only results in lost
tip material and redu es onta tor or starter life.
5. The ultimate tripping urrent of the installed
relay heater an be adjusted ±10% by using
Perform steps 1 through 5 under
“Coil Removal”.
2. Remove magnet from molded
over and movable arm.
3. Remove return spring from enter
of movable arm.
4. Remove molded over from
movable arm.
5. Depress and slide movable
onta t, spring, and spring seat from
movable arm.
6.
Remove s rews holding stationary
onta ts in pla e and remove
stationary onta ts
7. Reassemble devi e by reversing
pro edure
Do not attempt to remove or
repla e ar traps in ar hute over.
When rea
ar hute over will only fit one way and
is marked “TOP”
orner. Magnet and movable arm will fit
either way but will be quieter if
reassembled the same way they were
taken apart.
