Installation

This section provides information and procedures for the LevelMaster installation. Instructions provided in this section are
designed for a typical installation. Although there may be other methods of installation, it is recommended that technicians
perform the procedures in the order presented in this manual.
IMPORTANT NOTE: Read through this chapter before beginning installation and establish an installation strategy.
For safety installation requirements make sure to review section 1.3, Safety requirements for installation. It is very
important to refer to any instructions, drawings or wiring diagrams that are included with the LevelMaster. The
detail part of any assembly will typically use the documentation that accompanies the unit. If a discrepancy exists
between this manual and documentation that accompanies the unit, the unit's documentation will take precedence.

Site planning and requirements

Review the planning considerations and requirements for installation described in this section.
Installation options
There are several configuration options to install the LevelMaster. Before starting the installation, verify which configuration is
required to ensure that all components are available and that proper guidelines are followed. See section 2.5, Installation
scenarios for descriptions.
The two main installation scenarios are the general purpose installation and the hazardous location installation. The main
difference between the two types of installation is the additional safety barrier required for the hazardous locations (see section
3.1.4, Hazardous locations installation requirements). Both types of installation typically have the following:
LevelMaster: single or multiple LevelMasters (multiple units connected on an RS-485 bus)
A control system (host controller): a flow computer or remote controller used for automation and level control
IMPORTANT NOTE: The installation and configuration of the host controller (remote controller or flow computers)
is beyond the scope of this manual. Only pertinent details to their interface and communication configuration with
the LevelMaster are included in this manual. Refer to the user manual and the help files in PCCU32 for details. If
using third-party control equipment, consult their respective user manuals.
General planning
Before installing the LevelMaster(s) determine the following:
Company and site-specific policies regarding access to the tank(s) and connection to the LevelMaster once it is installed
inside of the tank. Local operator connection to the installed LevelMaster may be required for final verification or initial
monitoring or troubleshooting. Follow company safety guidelines and procedures applicable to local connections and
physical access.
Number of technicians required to install the unit and conduct the commissioning efficiently. Installation may require more
than one person depending on the height of the tank (length of the sensor), the weight of the unit, and the distance to
additional units in other tanks and to other devices (flow computers, remote controllers).
General purpose installation requirements
The following is required for first-time installation:
The appropriate number of floats and type: Float number and type vary depending on the liquid type or composition. Order
the appropriate float kit, if it was not shipped with the sensor. LevelMasters with batteryless floats require electronics board
part number 2104836-001 or later.
When planning to connect to additional units on an RS-485 bus, determine which units to configure as intermediate sensors
and which unit terminates the bus. RS-485 bus termination may be configured on hardware (onboard termination pin
jumpering) or on software depending on the type of electronics board on the LevelMaster. Jumper-based termination
requires access to the board. Ensure it is done prior to board installation or while the enclosure is still removed.
MasterLink software version 2.0 or later can be used for all board versions and it is required for support of batteryless floats.
It contains default or generic configuration files for every sensor length available.
