Actuator Does Not Control To The Proper Position; Table 9-5 Troubleshooting Control Action On Actuator - Honeywell HercuLine 10260A Installation, Operation And Maintenance Manual

9.2.4 Actuator does not control to the proper position.

Table 9-5 explains how to troubleshoot the actuator for the correct control operation.
Step
1 Check the connectors to the Motor
Positioner Board.
2 Check that cables are plugged into the
correct headers on NCS output board.
3 Check NCS Output signal.
4 Check input signal.
5 Check CW/CCW jumper
6 Check/Recalibrate
7 Replace CAT/PAT Board.

What to Do How To Do it or Where to Find the Instructions
Check to make sure connectors are securely
seated in headers on Motor Position board. See
Figure 4-5.
Check to make sure connector is seated in header
J4 on NCS board. See Figure 4-6.
On NCS Output Card, using a DVM, check that
the voltage across the pins of W11 (Figure 4-4) is
in the range of 0 to 1.25 Vdc. Check that voltage
is increasing for CCW operation and decreasing
for CW operation.
Using a DVM verify that the input signal at TB-30
to 31 (Figure 3-11) is in the range of 1 Vdc to 5
Vdc. If not check for the dropping resistor.
Upon change of input signal, if actuator travels to
0 % or 100 % check to make sure CW/CCW
switch and jumper (Figure 4-6) are in correct
positions.
Refer to Section 4 to recalibrate actuator. First
check Section 4.6 for proper positioning and
calibration of Non-contact Position Sensor.
Refer to the replacement procedure in Section 8 –
Replacement/Recommended Spare Parts.
