TopWorx Defender IOM

The TopWorx Defender IOM is a Turbine Trip Switch System designed to provide reliable and accurate monitoring of valve or actuator position. It features 10 leverless limit switches, each with adjustable target cams for precise switch tripping points. The Defender IOM is suitable for both clockwise (CW) and counter-clockwise (CCW) rotation and can be easily calibrated using the included Calibration Unit or an ohmmeter.

PROCEDURE

1. Determine if crank is clockwise (CW) or counter-clockwise (CCW) rotation to close the valve (view the box from the

crank end). NOTE: CW & CCW distinctions are important so access to the locking screws on the Target Cams can be

accomplished with approximately 90 degree rotation of the crank.

2. Note position of the crank arm when valve or actuator is at desired confirmation point. Remove the Customer supplied

linkage rod from the DEFENDER’s crank arm. Loosen the locking screws of all Target Cams with a 5/32" hex wrench

just enough to allow rotation on the shaft.

3. Temporarily disconnect the circular electrical connector plug from the DEFENDER. Attach the DEFENDER Calibration

Unit plug in its place. The Calibration Unit LEDs will illuminate when the corresponding switch senses its target. If a

DEFENDER Calibration Unit has not been supplied, reference the Limit Switch System wiring chart and use an

ohmmeter to assess the switch wiper positions.

4. For CW rotation, position the crank arm to its closed or 0% position. Block the crank arm in a position which will simulate

the 10% position (or whichever closed switch tripping point has been selected by the customer).Rotate the Target Cams

of switches 2, 4, 6, 8 &10 to a position which just trips each switch as indicated by the Calibration Unit or ohmmeter.

Torque the corresponding Target Cam screws to 45 in-lb. Caution! Failure to torque the screws to the specified value may

result in Target Cam slippage and possible switch damage.

5. Position the valve or actuator to its open or 100% position. Block the crank arm in a position which will simulate the 90%

position (or whichever open switch tripping point has been selected by the Customer). Rotate the target cam of

switches 1, 3, 5, 7 & 9 to a position which just trips each switch as indicated by the Calibration Unit or ohmmeter. Torque

the corresponding clamp collar screws to 45 in-lb. NOTE: For CCW rotation switches 1, 3, 5, 7 & 9 are closed.

Remaining switches are open.

6. Reattach the linkage rod to the correct threaded hole of the crank arm. Cycle the valve or actuator to assure desired operation.

7. Reattach the circular electrical connector plug which interfaces with the Customer’s control system to the Limit Switch Unit.

MAINTENANCE

The DEFENDER Turbine Trip Switch System requires no maintenance due to environmentally sealed Leverless Limit Switches

and shaft bearings. Bearings are pre-lubricated at assembly for the life of the unit. The Calibration Unit requires only periodic

replacement of the 9V battery as needed.
