Operation
• All tools are accounted for. If you
cannot locate a tool, do NOT energize
the equipment until the tool is found.
• Settings for protective relays are correct
2) Setting of Adjustable Protective Devices
Controllers may contain protective devices,
such as solid-state motor protection relays,
overcurrent relays, incomplete sequence
timers, and other devices critical to the
proper operation of the starter. Due to the
wide variation in job site parameters, these
devices are not set at the factory. It is the
purchaser’s responsibility to ensure that all
adjustable devices are properly set before
energizing the equipment. Warranty is void
if adjustable devices are not properly set
prior to initially starting the equipment.

WARNING
Failure to properly set adjustable devices may
result in equipment damage, personal injury,
or death.

CAUTION
Some control circuit configurations may
require control jumpers to let the contactor
close during the test procedure. Do NOT
jumper any isolation switch contacts such as
ISa or ISb. Using jumpers for these contacts
may result in equipment damage or injury to
operating personnel.
b. Electrically operate the contactor
several times. Inspect the armature
plate to verify that it fully contacts the
magnetic cores.
