SEISMIC TABLE Operation in EE185

Seismic Table Safety and Operation

The importance of lab safety cannot be emphasized strongly enough. The lab instructor is ultimately responsible for the students' safety. If you practice lab safety, students will be more willing to do so also.

In almost every state, instructors—as well as the school—are legally liable for student injuries. In case of an accident, being able to prove that lab safety has been taught, and that safety rules are enforced, becomes your legal protection.

Unfortunately the lack of formal safety training and inadequate maintenance procedures could expose you to accidents—and lawsuits. In an effort to help the lab instructor, a safety plan for the above test or experiment has been written below. Although these guidelines carry no legal weight, they can provide instructors with a general overview for lab safety. OVERVIEW During any seismic table testing process, there may be instances when concrete shards or specimen pieces may fall from the structure. In order to reduce exposure to injury for instructor, student and spectators, the following procedures will be in place during the testing procedure. The testing may be stopped at any time if any of the procedures are not followed. WINDOW PROTECTION Some sort of window protection will be required to keep foreign material from penetrating glass in observation decks. This can be either permanent or temporary. CAZ (Controlled Access Zone) The entire main floor of EE185 will be designated as the CAZ. During the testing and immediately afterward, access will be limited only to the MTS operator/Instructor. Only after it has been deemed safe, will observers be allowed in the CAZ.

BARRIER/CAUTION TAPE LOCATION

Barriers or caution tape will be placed at the lab double door to restrict access to the lab from the east. The large rollup door will be opened and used for observation overflow, but caution tape will restrict access to the lab through this door. Access to EE285A, the observation deck, will be via the pedestrian door and up the staircase to the deck. This area will be limited to 20 people, due to egress policies that will be enforced. Once the experiment starts, there should be minimal movement of people to avoid distractions to the operator. When the testing is completed, the instructor will determine if it is safe for access to the main lab floor. EXTENT OF SHAKE Due to the size and weight of the structure under test, the actual shaking will continue until the required frequency and amplitude have been reached. Safety of the students and facility will not be compromised by any additional testing other than the scheduled and predetermined frequency and amplitude. No “shake till it breaks”. EMERGENCY EGRESS In case of a catastrophic failure, the MTS operator/Instructor will have available to him, the emergency abort button for the MTS. After depressing this button, he is to immediately exit area through the west rollup door. There is a reinforced concrete wall for his protection without leaving the general area. NOISE PROTECTION There is no requirement for noise protection; observers will either be out side or behind glass on the second floor observation deck. ADDITIONAL SAFETY PROTECTION The MTS Machine operator/Instructor will be required to have a hard hat and safety glasses on during the testing. Again, observers will be far enough away to not require additional safety measures. AFTER SEISMIC TEST If after the successful test there is visible damage, it will be the responsibility of the MTS Operator/Instructor to determine if the structure is still safe. If it is determined that the structure is unsafe, then the MTS operator/Instructor will make provisions to secure structure until the damaged structure can be safely removed.

IN CASE OF CATASTROPHIC FAILURE

• MSDS Sheets are attached to safety plan (See format below) • MTS Operator/Instructor would determine Emergency call to:

o University Police Department 278-2132 o Fresno Fire Department Dial 9-1-1

CLEANUP

Clean up can be accomplished by placing fluid material in a container and sent to an appropriate waste disposal facility • Hydraulic Fluid can be cleaned up with:

o Fire retardant sawdust o Diatomaceous earth o Sand

BEFORE RUNNING PUMP

Ensure that the “OUTPUT PRESSURE” selector (5-6-7) is in the “LOW” (6) position.

Alternate Pump use by switching between both Pumps, Switch (10-11-12) will change pumps to evenly distribute the use between the two Pumps.

Make sure that all three “EMERGENCY STOP” buttons are in the released state, and ensure the “STOP” button on panel (4) is also released.

EMERGENCY STOP BUTTON LOCATIONS

(One at Panel, One at Vickers Pump, one at Console and one remote portable switch)

TO START PUMP

Make sure “RECIRC PUMP” in the “AUTO” (1) position.

Turn “OUTPUT PRESSURE” to “START” (7), and then turn selector to “LOW” (6) and allow pump to run for about 30 seconds in “LOW” (6), after which time selec-tor can be turned to “HIGH”(5).

To add second pump, turn “PUMP SELECTOR” to “BOTH” (11).

TO TURN OFF PUMP

Turn “OUTPUT PRESSURE” to “LOW” (6).

Press “STOP” (4) button and leave button depressed.

NOTE: If “FILTER DIRTY” (8) light comes on, system can be “RESET” (9), notify Technician if the light comes on just in case the light was caused by something else.

7

Starting up System

The login for the computer is “administrator” password is “admin”. There is also a password that is required to load the firmware and for any updates. This is usually done by the MTS Technician or by the Department Technician. This account is used only for upgrades and loading of firmware. The other passwords required to get into Tuning, Configuration, and Calibration will be addressed later.

Do not change any parameters in the “Network Settings”

Do not delete the “MTS_RT Account as this contains all the con-necting information from the computer to the MTS FLEX SE box.

System Loader and Station Manager and

Station Builder Icons

NOTE: PC must be up and running pr ior to starting the MTS FLEX-SE Controller. The On/Off switch for the MTS is on the back of control-ler. (System Loader must be loaded only the first time the computer is turned on.) Then Station Manager should be loaded.

8

Open Configuration ( In System Manager)

Under Configuration is a file called ftse.cfg, this is the file that

configures the Table Operation. Choose an existing Parameter Set

to use or to modify, just remember to “Save As” and do not write

over the original Parameter Set.

9

Station Manager

You can have the same configuration with different parameters, but each set of parameters must be saved in its own file. Examples are:

Tuned for a specific mass

Tuned for the table only with no mass present.

Windows for a specific Researcher.

Software Operation

1. Check Box marked “Exclusive Control” , if you do not check it the computer will not have control of the MTS.

2. The system incorporates interlock circuitry that allows for the ces-sation of a test if there is a system malfunction or operator error. Check Box marked “Reset Interlock 1”

3. Observe/Change limits of the Table:

3-1. Display/Station Setup

3-2. Channels

A. Stroke-Displacement limits set to 5”

B. Load-Force limits set to 55kips

3-3. If tuning is required, change from Operation to Tuning (Password “Tuning”), Then select parameters from “Tuning Fork”

Valve Tuning

4. Check valve response by metering output and spool position.

4-1. Display and Meters

4-2. Pull up Load, Stroke, Output, Spool Position, and

Command as shown below:

4-3. If it is a well-balanced Valve, Spool Position should be at

zero. Note: To get Spool Position to zero, valve tuning is

needed!

4-4. Stroke and Command should be equal, to have the output

(voltage to 5v) = 0.

This is for better performance of the Valve (Error=0).

If Stroke doesn't equal Command, manually match them

by clicking Manual Command on Station Controls.

First Enable then match Stroke and Command, then

Disable, Close Manual Command Box.
