Getting Started
System Startup
Before system startup, you should be familiar with the test fixtures, test
controller or electrical console, PC workstation, hydraulic power unit, and other
system components. This includes reading all of the sections in this Operation
Manual and the various additional documents supplied with the system. If
applicable, also read the vendor manuals supplied with the system. Observe all
safety practices and operating procedures to ensure proper use of the system.
Control console
The console power can be turned on after verifying that the following installation
procedures have been completed:
• cable connections are made and secured with proper strain relief,
• the power source is ready,
• the components are properly grounded, and
• the hydraulic power unit is shut off.
PC workstation
The cabling between the test controller and the computer should be checked for
proper routing and secured using attachment screws where necessary. It is
important that the physical integrity of these connections be maintained to ensure
safe and accurate operation of the system. When turning on power to the
computer, be sure that auxiliary equipment is also turned on at the appropriate
time. Refer to the test controller documentation for information regarding the
rear panel connectors provided for computer-controlled operation.
Hydraulic power unit
Ensure that electrical power is supplied to the HPU. Then turn on the HPU in low
pressure and check for leakage or improper operation. The cooling water supply
should also be checked for leakage or improper operation. When first starting up
the system or after the system has been idle for an extended period of time, run
the HPU for about 30 minutes or until the hydraulic fluid is up to
operating temperature.
Actuators
After checking the electrical and hydraulic power unit connections, the actuator
position control electronics (the Set Point control on the selected controller)
should be checked for signal polarity and control. This is accomplished by
performing the following steps:
1. Clear the area around the piston rod of obstructions.
2. Select the desired control mode (typically displacement).
3. Clear any active interlocks.
4. Apply hydraulic pressure by completing the following steps:
