Auxiliary Contact Setup
Procedure
See
for part numbers required for this procedure.
To facilitate the set-up procedure, the contactor is held closed mechanically
with a clamping fixture (
). It is important that the contactor is held
closed tightly with the armature plate against the magnet cores when gauging
the overtravel and auxiliary positioning.
To aid in closing the contactor mechanically, a clamping fixture is
recommended (PN-195987).

1. Loosen the nuts on auxiliary assembly retaining bolt. This requires
loosening and removal of the first nut that secures a ground wire at this
location. Leave the nut loosened enough to permit the assembly to slide
along the adjustment slot as shown in
IMPORTANT
This procedure applies to adjustment of existing auxiliaries and
installation of new auxiliaries. Under normal conditions,
auxiliaries last at least 1,000,000 operations. If auxiliary contacts
must be replaced, discard the entire assembly and install a new
assembly. Discarding the entire assembly is easier than replacing
one contact block.
