MTS Landmark™ Tabletop Load Units - Product Information
Connecting Cables
Your controller manual should have cabling information about the connections described in this
section. Most controller manuals provide the signal pinouts of the connector, assembly numbers for
standard MTS cables, and cable specifications for cables you may build.
Prerequisite
You must have either a cable assembly drawing of your test system, or you must know the system
controller well enough to determine each type of cable connection.
Cable connections
The following load unit components are connected to the test controller via cables:
l
The force transducer (load cell).
l
The load unit control panel; the control panel contains the emergency stop and crosshead lock
signals.
l
The servovalve.
l
The actuator manifold. The actuator manifold might include a proportional valve or solenoid
valves. Controllers can have two connectors (one for each HSM type) or one connection that
can be configured. See your controller documentation.
l
The displacement sensor (also called a linear variable displacement transducer or LVDT).
l
For axial/torsional load units with hydraulic rotary actuators, the encoder (rotational sensor).
For axial/torsional load units with electromagnetic rotary servo motors, the servo motor and the
encoder are connected to the enclosure. The enclosure is connected to the controller.
Another connection is the ground connection. The ground connection is located on the back of the
control panel. This is usually connected to a chassis ground on a console or the controller chassis.
