4. INSTALLATION OF LIN-300 SERIES MODULES
4.1 Preliminary considerations
•
LIN-300 Series modules are signal condi-
tioning units which, when supplied with 24VDC
and paired with matching sensors, deliver a 4
to 20 mA linearized raw output signal repre-
senting a distance which can be used by
AGMS and ZOOM systems, ZPU-5000, PCU-
5000, PCU-100 Programmable Monitor, or
third-party instrumentation.
•
The sensor is connected to the LIN-300
module through a triaxial cable with an SMA
connector, while power input and signal output
share an extension cable connected to the
LIN-300 M12 socket.

•
LIN-300 modules are usually installed in pairs on a mounting plate enclosed in a wall-mounted protection
box.
•

DC
power input is required to power up the LIN-300 modules. Power can be provided from an
external source, such as from an XPSP-224P External Power Supply panel.
•
The extension cable can be assembled on site, using 4-conductor shielded cable and an M12 connector,
or a standard molded M12 cable assembled can be used. The standard cable offered by VibroSystM is a
molded M12 cable, 30m (100 ft.) long, and is rated for a maximum operating temperature of 80
° C (176 ° F).
Since this cable is not calibrated, it can be cut.
•
Installation of the LIN protection box, protective conduits, and triaxial cables should be completed before
proceeding with the installation of the M12 extension cable, and connection of the LIN-300 modules.
•
A flexible conduit must be installed between the LIN-300 protection box and the location of the power
source and data-receiving instrumentation. This conduit, attached with liquidtight connectors and
supported by conduit clamps, will protect the M12 extension cable.
•
Cable length from LIN-300 signal conditioner to instrument should not exceed 300m (1000 ft.) for the 4-
20 mA output signal.
A connection that has not been correctly tightened or has become loose can cause erratic
readings. To ensure correct system operation, all connections must be correctly
tightened.
