CHANGING OUTPUT SHAFT
DIRECTION OF TRAVEL
Direction of travel is defined as the direction
of output shaft travel produced by an increasing
signal. Direction of travel is determined by
looking at the end of the output shaft. Unless
otherwise specified at the time of order, the
factory set output shaft travel is to extend in
response to an increasing signal.
The following procedure should be followed
to check or change the direction of travel of the
output shaft.
This is up to a three procedure process
depending on the actuator control option. The
procedures are as follows:
1. Interchange limit switch wires.
2. Calibrate position feedback signal.
3. Test/calibrate the Demand input signal.
CAUTION
Be sure the actuator is disconnected
from the line voltage and the auxiliary
switches are disconnected from
the external power sources before
proceeding with direction change
procedure.
Interchange Limit Switch Wires
1. Remove the control module cover.
2. To reverse the output shaft direction of travel,
the wires to the common terminals of travel
limit switches S3 and S4 must be interchanged.
The common terminals are those located
furthest from the switch labels and nearest
to the power transformer (see Figure 4, this
page).
3. For extend output shaft travel on an increasing
signal, the orange wire must be on the
common terminal of S4 and the brown wire on
the common terminal of S3.
4. For retract output shaft travel on an increasing
signal, the brown wire must be on the common
terminal of S4 and the orange wire must be on
the common terminal of S3.
5. Locate plug P4 on the control board. It is a
three wire plug with a grey, blue and yellow
wire attached to it. See Figure 6, page 18, for
the location of plug P4.
6. For extend output shaft travel on an increasing
signal, plug P4 must be attached to the
terminal labeled CW. Note that this is a locking
type plug and must be located properly in its
receptacle. The tapered side of the plug must
be against the tapered side of the receptacle.
See Option 5 or 7 wiring diagram, page 7 or 8.
7. For retract output shaft travel on an increasing
signal, this plug must be attached to the
terminal labeled CCW.
8.
If the direction of travel of the output shaft is
changed; the feed back signal, the feedback
potentiometer, and (for Option 7) the input
signal must be recalibrated. See instructions
beginning on page 16.
9. End of procedure for the control option 3 drive.
For options 5 and 7, continue to Feedback
signal calibration procedure (page 16).
