When connecting to Totalflow equipment (flow computers or remote controllers), PCCU32 software is required. Adding and

setting up the LevelMaster application is required for communication between the Totalflow devices and the LevelMaster.

Hazardous locations installation requirements

In addition to general requirements in section 3.1.3, above, the installation and grounding of the LevelMaster in hazardous

locations require the following:

Intrinsically safe Totalflow CSA-certified barrier board

Grounding must meet the requirements as specified in the National Electrical Code (NEC) or the Canadian Electrical Code

(CEC).

LevelMaster sensors are CSA-certified for installations in hazardous locations when connected through Totalflow CSA-certified

barrier boards in accordance with the Totalflow certification drawings (see Figure 5).

Class 1, Division 1, Group D when connected through Totalflow CSA-certified barrier boards. One barrier board supports up

to four level sensors, with a maximum distance of 500 feet.

Class 1, Division 1, Group C, D when connected through Totalflow CSA-certified barrier boards . One barrier board

supports up to three level sensors, with a maximum distance of 500 feet.

IMPORTANT NOTE: Figure 5 shows the barrier enclosure (not the actual barrier board). The barrier board

required depends on the location classification. Two board options are available for Class 1, Division 1 locations.

For Group D, barrier boards must be part number 2100336-001. For Group C and D, barrier boards must be part

number 2100336-002. Barrier boards are sold with their enclosure. Replacement barrier board kits are also

available. Contact ABB for details.

Unpack and inspect

The LevelMaster is shipped in a specially designed shipping carton which contains the sensor unit, electronics board with

enclosure, mounting components, parts list, wiring and interconnect diagrams. If an intrinsically safe barrier is provided, it and its

associated hardware are shipped in a separate carton.

IMPORTANT NOTE: If there is any damage to the shipping carton, keep the carton and packing materials until the

contents are inspected and found to be damage-free.

Inspect all of the shipping cartons for damage.
