Actuator Cw/Ccw Operation Is Not Correct; Table 9-4 Troubleshooting Cw/Ccw Operation - Honeywell HercuLine 10260A Installation, Operation And Maintenance Manual

10260A Series Actuators Installation, Operations, and Maintenance Manual

9.2.3 Actuator CW/CCW operation is not correct.

Table 9-4 explains how to troubleshoot the actuator for proper CW/CCW operation.
Step What to Do
1 Check that the cables are
plugged into the correct
headers on the NCS Output
Board.
2 Check that the shaft turns
correctly for CCW drive.
3 Check that shaft turns
correctly for CW drive
4 Check/Recalibrate.
5 Replace the NCS Output
Board.

How To Do it or Where to Find the Instructions
On the NCS Output Board insure that the following are
connected: (See Figure 4-6.)
J5 – BRN, BRN, YEL
J3 – RED, GRN, WHT
W10 – jumper pins 1 to 2 – CCW
W10 – jumper pins 2 to 3 – CW
J4 – ORN, YEL (If Motor Positioner board is present.)
If actuator is used in CCW direction and input is increasing
measure, using a DVM, the voltage at W11 See Figure 4-4.
It should be increasing from 0 Vdc to 1.25 Vdc as input
increases and shaft rotates CCW. If this is not the case go
back to STEP 1 and check W10 jumper position. See Figure
4-6.
If actuator is used in CW direction and input is increasing
measure, using a DVM, the voltage at W11. See Figure 4-4.
It should be decreasing from 1.25 Vdc to 0 Vdc as input
increases and shaft rotates CW. If this is not the case go
back to STEP 1 and check W10 jumper position. See Figure
4-6.
Refer to Section 4 to check calibration and to recalibrate.
First check Section 4.6 for proper positioning and calibration
of non-contact sensor.
Refer to the replacement procedure in Section 8 –
Replacement/Recommended Spare Parts.
