Damper System Operation Getting Started

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:
