Chapter 3: Additional System Details
38 M47-17028-EN
The 59 Series control unit receives messages from the computer and sends the message to the testing
system to perform the required operation. While testing, the controller receives data from the load and
position transducers on the frame and sends the data to the computer. A frame interface board mounted
inside the control unit provides signal interfacing between the controller and the system components.
Communication between the 59 Series control unit and the computer is accomplished through an
Ethernet Frame Interface (EFI) that is mounted inside the 59 Series control unit.
For detailed information on the computer system, please refer to the computer manufacturer’s literature
that was provided with the system. For more information on the controlling software, refer to the
software’s On-line Help system or to the manual provided.
Electrical panel
System electronics are mounted on an electrical panel. The panel is mounted inside the front of the
frame base. The electrical panel houses:
• A motor starter for the pump motor, with overloads
• A frame interface board
• A +/-12VDC power supply for the frame interface board
• A 59 Series control unit that houses the conditioning cards and digital signal processing card
• A +5/+12/-12VDC power supply to provide power to the 59 Series control unit
Computer systems are typically purchased from Instron with the testing system, however they may be
customer supplied. If this is the case, refer to any information provided by the computer vendor in
regards to its operation, warranty, etc. Instron is not responsible for customer supplied equipment.
Disconnect the electrical power supply before removing the covers to electrical equipment.
Disconnect equipment from the electrical power supply before removing any electrical
safety covers to replace fuses, inspect or clean the system. Do not reconnect the power
source while the covers are removed. Refit covers as soon as possible.
