Section 4: Set-up/Start-up Procedure
Set-up/Start-up Procedure
4.7.3.6 With the LOCAL – OFF – REMOTE Switch set to LOCAL, push the OPEN
PUSHBUTTON and allow the Actuator to travel to the Open position,
rotated fully counterclockwise.
4.7.3.7 Push down and slide Target for OPEN LS-1 counterclockwise until it is
off the switch in the counterclockwise direction.
4.7.3.8 Now, push down and slide the Target for OPEN LS-1 clockwise until the
CLOSE light just goes out.
4.7.3.9 Push the CLOSE PUSHBUTTON and allow the actuator to rotate
clockwise to the fully closed position and check to see CLOSE LS-2 is
operated; the OPEN light should go out. Cycle the actuator open and
closed a few times checking the setting of CLOSE LS-1 and OPEN LS-2.
4.7.4 Open Limit Switch Adjustment
4.7.4.1 With the actuator in the Open Position, rotated fully counterclockwise,
the Target for OPEN LS-1 will need to be adjusted.
4.7.4.2 Reconnect electrical power to the unit.
4.7.4.3 Push down on the Target for OPEN LS-1 and move counterclockwise
until it is off of the switch in the counterclockwise direction. Both the
OPEN and the CLOSE lights on the PBM (Pushbutton Module) should be
illuminated at this point.
4.7.4.4 Now, push down and slide the Target for OPEN LS-1 clockwise until the
CLOSE light just goes out. It is important to always adjust a Target in
the opposing direction of the valve travel to get an accurate setting.
4.7.4.5 With the LOCAL – OFF – REMOTE Switch set to LOCAL, push the CLOSE
PUSHBUTTON and allow the Actuator to travel to the Close position,
rotated fully clockwise.
4.7.4.6 Push down and slide Target for CLOSE LS-2 counterclockwise until it is
off the switch in the clockwise direction.
4.7.4.7 Now, push down and slide the Target for CLOSE LS-1 clockwise until the
OPEN light just goes out.
4.7.4.8 Push the OPEN PUSHBUTTON and allow the actuator to rotate
counterclockwise to the fully open position and check to see OPEN LS-2
is operated; the CLOSE light should go out. Cycle the actuator open
and closed a few times, checking the setting of CLOSE LS-1 and OPEN
LS-2.
4.7.5 Four Limit Switch Models
4.7.5.1 If your unit utilizes four switches LS-3 OPEN and LS-4 CLOSE, adjust
in the same manner except you will need to use a continuity tester
on the terminal strip to detect switch operation. LS-3 is connected to
terminals A31, A32 and A33. LS-4 is connected to A35, A36 and A37.
Look at these switches on the wiring diagram for exact configuration.
