4.4 ELECTRICAL TESTING
VERIFY PROPER VOLTAGE
The TFT Ball Intake Valve RC has built in circuit protection to guard against a circumstance where the unit’s movement is blocked
before reaching its full travel limits. Without this circuitry the motor would stall, overheat, and could be permanently damaged.
IMPORTANT
- When mechanical installation and electrical connections are complete, perform the following test to verify voltage
supply is adequate and the current limiting feature is functioning.
1. Apply power to Valve Control.
2. Press OPEN or CLOSE button and hold until valve reaches stop position. Continue to hold button down.
3. Once movement is stopped, manually turn override knob in opposite direction while continuing to hold button
down. If knob can be turned, then voltage supply is adequate. If knob can’t be turned and motor continues
to operate, then the current limit was not reached because the voltage supply or wiring is not adequate.
NOTE: Override knob will only turn in one direction.
To ensure proper voltage to the Ball Intake Valve RC, the wiring needs to be checked for proper gauge for the installed length of
wire, and for proper termination. Also, ensure that the power source supplying the BIV RC and the grounding are adequate (other
electrical loads on a shared circuit with the BIV RC may cause a low-voltage situation).
In addition to motor damage, a further consequence of low voltage could be that the valve will not open or close properly or fully.
SET TRAVEL STOPS
When proper voltage is verified, perform the following to set the full travel limits.
1. Apply power to Valve Control.
2. Press CLOSE button and continue to hold until valve is fully closed. Motor must stop by current limit method. If motor continues
to operate see proper voltage section above.
3. Press OPEN button and continue to hold until valve is fully open. Motor must stop by current limit method. If motor continues
to operate see proper voltage section above.
4. Position indicator lights will now track valve movement.

ASSEMBLY
The handwheel is shipped from the factory on the right hand side of the valve. The hand wheel can be switched to the left hand side
for convenience or if it interferes with other equipment on the pump panel.
To move the handwheel to the opposite side, remove the retaining ring on the end of the shaft. Pull the shaft out of the gear box. As
the shaft is withdrawn, grasp the small key on the shaft so it does not get lost. Remove and switch the two plastic bushings that come
out of the sides of the gearbox. The bushing with the large hole is installed on the same side as the handwheel.
Look through the gear box and note approximate position of the keyway in the worm inside the gear box. Slide the shaft into the
gearbox on the opposite side of the gear box with the key oriented the same as the keyway. A small dab of grease will keep the key
place. Rotate the shaft until the key finds the keyway and push the shaft in until it stops. Reinstall the retaining ring. Do not over
expand the retaining ring.
