LevelMaster 7100 Quick Start 

This guide includes basic steps for a new general-purpose 
installation and setup in an unclassified area. For hazardous 
location installations refer to online publications. 

 

IMPORTANT NOTE:

 Installations may involve single or multiple 

interconnected units and mixed board types. For multi-unit 
installations, determine intermediate and last units in the 
connecting bus to terminate the RS-485 bus correctly.

DANGER – Bodily injury:

 Configure the LevelMaster before 

inserting into the tank. Follow your company policies and safety 
guidelines to complete installation. 

Install LevelMaster components 

With the sensor positioned and supported horizontally: 

 

Wrap Teflon

®

 tape, or another sealing material, around cord 

connector and tank port bushing threads. 

 

Slide the components into the bottom of the LevelMaster in the 
following order: Cord connector, tank port bushing, floats. If using 
two floats, slide the oil float on first (see Figure 1.)  

 

Slide and tighten the float clamp at 1 inch above the bottom of 
the casing.  

Assemble local communication cable 

Connect the converter cable and adapters based on board type 
and ports available on the laptop (see Figure 2.)  

 

Connect the RS-485 cable adapter to the RS-485-to-RS-232 
converter cable.  

 

If using a laptop without RS-232 ports, connect the RS-485-to-
RS-232 converter cable to the RS-232-to-USB converter. 

Connect to the LevelMaster  

 

IMPORTANT NOTE: 

Ensure MasterLink 2.0 is already installed in 

the PC or laptop. MasterLink has context-sensitive online help. 
Click 

Help

 on the screen of interest for details. 

To configure the LevelMaster, connect to the electronic board: 

 

Remove cover from the electronic enclosure and pull the 
electronic board up gently without disconnecting it from the 
sensor assembly. 

 

With a small slotted screw driver, remove the connectors from the 
onboard communication and power terminals. Save these 
connectors for wiring. 

Use the local communication cable to connect the 
laptop to the electronic board.  

 

Insert the red wire connector to the cable assembly battery. 

 

Start 

MasterLink

 on the laptop.  

 

At the main screen, add a location for the new unit: 

a.

 

Right-click inside the screen (white area) and select 

Add 

New Location

b.

 

Enter up to 25 characters for a location name. 

c.

 

Click
