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 verifi ed, 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.
4.5 BALL INTAKE VALVE RC MANUAL OVERRIDE
11/16" [18 mm] Hex
The Ball Intake Valve RC is motor driven but also has an override
handwheel for operating the valve manually. The override
handwheel may also be used in the event of power failure. If
electrical power is supplied to the control panel then the LED valve
position display will track the valve’s position as the handwheel is
moved. If the handwheel is moved while there is no power to the
electric controls than the LED valve position display will be in error
when the electric power is reconnected. The LED valve position
indicator will self correct the fi rst time the valve is cycled under
electric control.
If more compactness is desired the override handwheel may be
removed. The drive shaft has a hex so a wrench or socket may
be used for manual override. If the manual override handwheel is
removed assure that the correct size wrench or socket is available
in the event of power failure.

Crank Handle Off set
When equipped with a crank handle, two off set positions are available to adjust
the swing radius of the crank and knob as shown in fi gure 4.6. The longer off set
position off ers reduced eff ort to operate the valve. The shorter off set is available
to avoid interference with other equipment on the apparatus. To change the
off set, remove two 1/4”-20 x 1/2” button head cap screws from crank. Place
crank in desired position and replace screws. Apply Blue Loc-Tite thread locking
compound to all of the screw threads.
