WARNING
FIRE OR EXPLOSION HAZARD
CAN CAUSE SEVERE INJURY OR DEATH
When auxiliary switches control combustion
equipment, incorrect wiring of the switches can
allow the burner to come on at high fire. Check
auxiliary switch wiring and cam adjustment be-
fore turning on the system. Watch the controlled
equipment through one complete cycle. Shut the
system down immediately if switches do not
correctly sequence the equipment.
Checkout
Use the controller to run the motor fully open and then
fully closed. Make sure that the auxiliary equipment starts
and stops at the desired points in motor rotation. When
checkout is complete, return the controller to the desired
setting.
