CAUTION:
The power must be off during this procedure so as to avoid
damage to the actuator.
Do not make adjustments to the mechanical end stops when
actuator is in motion.
All steps below must be completed before normal operation.
Instructions - Fully-open and fully-closed position limit switches
Actuators come standard with two limit switches, LS1 for fully-open and LS2
for fully-closed positioning. Two auxiliary limit switches (LS3 & LS4) are
optional for fully-open and fully-closed position feedback.
