Actuator Cw/Ccw Switch Does Not Operate Correctly; Table 9-7 Troubleshooting The Cw/Ccw Switch - Honeywell HercuLine 10260A Installation, Operation And Maintenance Manual

9.2.6 Actuator CW/CCW Switch does not operate correctly.

Table 9-7 explains how to troubleshoot the actuator CW/CCW Switch.
Step
1 Check that the CW/CCW Switch and
the jumper on the NCS Output Board
are correct.
2 Continue Step 1.
3 Check terminal wiring.
4 Check Non-contact Sensor.
5 Replace CW/CCW Switch.
6 Replace NCS Output Board.

What to Do How To Do it or Where to Find the Instructions
Verify that when the CW/CCW Switch is toward
the CCW position that jumper W10 on the NCS
Output Board is between pins 1 and 2. See Figure
4-8.
Verify that when the CW/CCW Switch is toward
the CW position that jumper W10 on the NCS
Output Board is between pins 2 and 3. See Figure
4-8.
Using the wiring label located on the cover of the
actuator verify that the wiring to the units is
correct.
Verify that the NCS sensor is positioned correctly.
Position actuator to 0 % SPAN for CCW drive
(100 % SPAN for CW drive) and make sure NCS
spoilers are in zero position. (See Figure 4-4.)
Using a DVM, measure voltage between pins on
W11. Voltage should be between 0.01 V and
0.02 V in ZERO position and should increment as
actuator goes CCW.
See Section 4 to recalibrate.
Refer to the replacement procedure in Section 8 –
Replacement/Recommended Spare Parts. Or if
an external controller is being used refer to it's
Operators Manual.
