Location Wiring
The wiring schematics differ within the LevelMaster depending on site
location. Non-hazardous sites do not require the use of a barrier board,
while hazardous sites do require one. The following instructions make
the assumption that the LevelMaster is installed in a hazardous site.
Additionally, the following information details the wiring schematics for
three different types of hosts: XSeries Flow Computer (XFC), XSeries
Remote Controller (XRC) and LevelMaster Controller (LMC). It is
possible to connect directly to the LevelMaster utilizing only a laptop that
is running MasterLink
®
software wherein the user plugs the computer
directly into the LevelMaster’s electronic board using a converter cable
(P/N 2100241-xxx).
The LevelMaster also has the ability to be daisy chained to additional
LevelMaster devices. Currently, the maximum number of LevelMasters
that can be daisy chained together is four within a Class Division 1
Group D area.
For all installations, use cable (P/N 2011648-001) or an equivalent cable
with a twisted, shielded wire for communications.
