DLC3010 Digital Level Controller

September 2014

Coupling

If the digital level controller is not already coupled to the sensor, perform the following procedure to couple the digital

level controller to the sensor.

1. Slide the access handle to the locked position to expose the access hole. Press on the back of the handle, as shown

in figure 2, then slide the handle toward the front of the unit. Be sure the locking handle drops into the detent.

2. Set the displacer to the lowest possible process condition, (i.e. lowest water level or minimum specific gravity) or

replace the displacer by the heaviest calibration weight.

Note

Interface or density applications with displacer/torque tube sized for a small total change in specific gravity are designed to be

operated with the displacer always submerged. In these applications, the torque rod is sometimes resting on a stop while the

displacer is dry. The torque tube does not begin to move until a considerable amount of liquid has covered the displacer. In this

case, couple with the displacer submerged in the fluid with the lowest density and the highest process temperature condition, or

with an equivalent condition simulated with the calculated weights.

If the sizing of the sensor results in a proportional band greater than 100% (total expected rotational span greater than 4.4

degrees), couple the transmitter to the pilot shaft while at the 50% process condition to make maximum use of available

transmitter travel (±6_). The Capture Zero procedure is still performed at the zero buoyancy (or zero differential buoyancy)

condition.

3. Insert a 10 mm deep well socket through the access hole and onto the torque tube shaft clamp nut. Tighten the

clamp nut to a maximum torque of 2.1 NSm(18 lbfSin).

4. Slide the access handle to the unlocked position. (Press on the back of the handle as shown in figure 2 then slide the

handle toward the rear of the unit.) Be sure the locking handle drops into the detent.
