9.2.2 Actuator Slidewire Output does not function.

Table 9-3 explains how to troubleshoot the actuator Slidewire Output failure.
Step
1 Check that the cables are plugged into
the correct headers on the NCS Output

What to Do How To Do it or Where to Find the Instructions
On the NCS Output Board insure that the
following are connected: (See Figure 4-7.)
J5 – BRN, BRN, YEL;
J7 – ORN, ORN, GRY;
J3 – RED, GRN, WHT:
J6 – RED, YEL, BLU.
J4 – ORN, YEL (If Motor Positioner board is
present.)
Using the Digital Voltmeter measure the voltage
from pin 34 to pin 36 on TB. This voltage should
be in the range of 1.000 Vdc to 20 Vdc. See
Figure 3-11.
Using a DVM measure the voltage between the
pins on W11. The voltage should be in the range
of 0 to 1.25 Vdc. See Figure 4-4.
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.
