Details

PRINCO’s L2740 Versa-Point™ gives you the safety and convenience of remote mounting plus the flexibility of either four independent set points or
zone control with two additional set points.

Remote adjustability minimizes the need for personnel to climb high tanks, silos, bins, or enter other hazardlous locations.

The distance between the sensor assembly and the control unit can be as great as 3000 feet. The control panel and sensor assembly are connected
by ordinary three-conductor cable. When set up as a four-point level controller, it is an ideal multiple point level alarm for applications requiring high alarm, high-high alarm, low alarm, and low-low alarm, all operating from a single probe.

As a zone control with two additional level points, it is ideal for lift stations, batching operations, and industrial sumps. Both set points, which define the zone as well as the two level points, are independently adjustable.

Mode of operation for zone control may be selected for either pump-up or pump-down. Likewise, the level points, whether high or low, may always
be operated fail-safe. The zone may occupy virtually any portion of the overall range, from 1 to 100 percent. Location of the level points may also be anywhere in the overall range, outside or inside the zone.

All set points and zone limits may be independently set for either high or low fail-safe.
