The Type HGA11 is a hinged armature type, high speed auxiliary relay.
coil is energized, a magnetic flux flows through the armature pole piece and
attracts the armature.
armature.
These auxiliary contacts can be normally open or normally closed, and can
be used to make or break auxiliary circuits.

MECHANICAL ADJUSTMENTS

There should be at least 1/16 inch wipe on normally closed 11b11 contacts and
normally open 11 a11 contacts, as measured at the top of the moving contact carrier.
This is determined by operating the armature by hand and checking that there is at
least 1/16 inch movement of the top edge of the contact carrier after the contacts
have made.
When the armature is operated by hand, 11a11 contacts should make within 1/32
inch of each other, i. e. , with one contact just making, the gap of the other should
never be more than 1/32 inch.
There should be at least 1/32 inch clearance between the armature tailpiece and
the bottom inside surface of the cover for all back connected relays with cover.
special cover with cutouts in the sides is-available to check this clearance.

PICKUP TEST

Pickup is defined as the m1mmum voltage or current at which the armature
operates and seals firmly against the pole piece.
