Wiring Strain Relief

Tie down points and ratcheting tie wraps are provided to secure the wiring to the PCB mounting plate.

This helps prevent wire strain from being transmitted to the connection at the terminal block and to keep

the wiring from chafing on the cover when tightening and under vibration. Failure to secure the wiring

could result in intermittent connections resulting in intermittent operation or shutdown conditions. Allow

for additional wire service length between the tie down points and the connectors to reduce strain on the

wire at the connector interface and to allow the black pluggable connector to be removed.

Shield Installation Notes

• Wires exposed beyond the shield should be as short as possible, not exceeding 50 mm (2 inches).

• The shield termination wire (or drain wire) should be kept as short as possible, not exceeding 50 mm

(2 inches), and the diameter should be maximized where possible.

• Installations with severe electromagnetic interference (EMI) may require additional shielding

precautions. Contact Woodward for more information.

• Do not ground shield on both ends, except where permitted by the control wiring diagram.

Failure to provide shielding can produce future conditions that are difficult to diagnose. Proper shielding

at the time of installation is required to ensure satisfactory operation of the product.

Position Feedback

There are two outputs for valve position feedback on each of the QuickTrip’s three valve modules (12

outputs total). Each of the two outputs features redundant connections. Both TRIP outputs and both RUN

outputs operate as normally open. The outputs can be wired to either switch load from positive supply or

switch load to ground. The user must supply the external 24 V supply for the output to function properly.

If using the Woodward ProTech TPS logic solver, the voltage may be supplied using the on-board discrete

power terminals (24 VDC, 0.050 A).
