PUREX EXH SYSTEM ACCEPTANCE TEST PROCEDURE
6.3 Exhaust Fan EF1-3 Inlet, Outlet, and Vortex Damper Testing
6.3.1 Ensure that the actuators for all inlet, outlet, and vortex dampers are properly
mounted on pedestal bases and disconnected from the damper actuation linkages.
6.3.2 Ensure that all four limit switches are installed for each actuator and that the
initial actuator stroke will be limited to approximately three and one-half inches.
Limit switch mounting positions (right-hand side of the actuator barrel or left-hand side of the
actuator barrel) are established with actuator barrel being viewed from the motor end.
6.3.3 Ensure that type RP1 limit switches are mounted on the left-hand side of the
actuator barrel and RP2 limit switches are mounted on the right-hand side of the
6.3.4 Ensure that all wiring for actuator motors and limit switches is installed,
connected, and ready to be energized.
6.3.5 Whenever electrical leads are lifted and landed,

6.3.6 If, during limit switch and actuator testing, any unexpected conditions are
encountered or if any unexpected equipment operation is noted, then immediately
stop testing, inform the Test Director of the problem, and resume testing only
when directed to do so by the Test Director.
6.3.7 Lift the 24 Vdc supply wire for the actuator controller at terminal TS5-EF1-3-1.
6.3.8 Lift the 2.2 KQ "pull-up" (PU) resistor at terminal TS5-EF1-3-3.
6.3.9 Lift the 2.2 KS2 "pull-up" (PU) resistor at terminal TS5-EF1-3-11.
6.3.10 Lift the 2.2 KM "pull-up" (PU) resistor at terminal TS5-EF1-3-15.
6.3.11 Connect the Hall Effect limit switch test box test wire from TB-1 +24 Vdc to
6.3.12 Connect the Hall Effect limit switch test box test wire from TB-1 DC COM to
