## Q330 and Packet Baler

## Equipment Installed in TA Vault

## VSAT Antenna and PV Array Examples

## Seismometers

- Borehole Installations
- KS54000i
- CMG3-TB
- Surface Installations
- STS-1/VBB
- STS-2
- CMG-3T
- FBA-23 (Accelerometer)
- Episensor (Accelerometer)

## Seismometers

- Basic Information
- NEVER move a seismometer without locking the mass.
- Prevent temperature changes to seismometer and inside vault.
- Eliminate seismic noise near seismometers.

**Notes:**
Air movement around seismometers causes noise.

## Seismometers

- Operator Maintenance Requirements
- Depends on the type of seismometer
- Monitor the data quality
- Check the mass positions (if data is available)
- Center the masses (not possible on all seismometers)
- Align the seismometer if it has been replaced (surface instruments only)
- Troubleshoot problems

## Seismometers

- STS-2
- Monitor the data for problems
- Check mass positions on status screen
- Center all masses if any mass is more than + or- 5 volts from zero. Use the current procedure provided by GSN Maintenance
- Center the masses whenever power is lost to the seismometer
- Troubleshooting
- If data is noisy or spiking, check for moisture problems and re-level the instrument
- If there is no seismic or mass position data, this is most likely due to a faulty Host Box
- Request help from ASL

## Grounding

- Grounding is for protection of personnel and reliable equipment operation.
- Lightning or equipment failures can cause voltage transients that can damage equipment or kill you.
- All equipment is grounded to one place: Single Point Ground
- Maintain the integrity of the grounding system installed with the GSN equipment.

**Notes:**
Create a lightning presentation.
Explain Tranzorb, enhancement, hemisphere of influence.

## Grounding

- The importance of correctly installing and maintaining a reliable grounding system is explained.
- Exothermic welding connections are demonstrated.

## System Software

- Training conducted by Software Engineers and Field Engineers.
- On hardware systems configured for the specific stations.
- Running the station operational software.

## Quality Control

- Quality Control analysts explain how they verify seismic content of the data.
- Field Engineers and Quality Control analysts demonstrate and explain the capabilities of data analysis software.

## System Maintenance

- Training is conducted by Field Engineers on hardware configurations for each specific station.
- Test systems are setup for any unique hardware configurations.

## Trouble Shooting

- Conducted by Field Engineers to locate common problems.
- Present solutions for possible temporary repairs to keep the station operational.

## PRIMARY PROBLEM TROUBLESHOOTING POINTS

-    Before contacting ASL for technical assistance with a station problem please insure the following troubleshooting  procedures have been completed.

## Is power available at all equipment locations? Has there been a commercial power outage?

If power is available but a component is not functioning, are fuses blown?

Verify normal operation of all LED’s on the system and make notes to inform GSN Maintenance if they are ON or OFF or FLASHING.

- If power is available but a component is not functioning, are fuses blown?
- Verify normal operation of all LED’s on the system and make notes to inform GSN Maintenance if they are ON or OFF or FLASHING.

**Notes:**
There is a list in this document package of normal light indications.

## Note status of Radio or Modem comm- link LED’s if you have this hardware.

Inform GSN Maintenance of any electrical storms that may have been in the area when the problem started.

If you are not familiar with the above  actions ask for guidance from GSN Maintenance.

## LIGHTS ON THE QUANTERRA SYSTEM(Example of a Troubleshooting Checklist)

**CPU** Central Processing Unit Board
- FAIL (red) **OFF = Normal Operation**.
- STATUS (yellow)** FLASHING = Normal operation**.
- RUN (green)** FLASHING = Normal operation**.
- SCON (green)** ON = Normal operation**.
**MVME 712/M** Interface Module
- Visible through a hole in the front panel are two lights (yellow and green) **ON = Normal operation**.
- The light in the terminator connector on the front panel (green) **ON = Normal operation**
**QPWR** Quanterra Power Module
- The top light (yellow) **OFF = Normal operation**.
- The top light is a blown fuse indicator for the incoming power and will also illuminate when the top power switch is turned off.
- The center light (yellow) **OFF = Normal operation**.
- The center light is also a blown fuse indicator. ON = 24 VDC power is lost to the QAP modules.
- The bottom light (green) **ON = Normal operation**.
- If the bottom light is not illuminated, there is less than 20 VDC available at the input connector.
**QDP** Quanterra Digital Processor Modules
**All 3 (red) lights Flashing brightly each second = Normal operation**.
- All 3 lights on continuous = CPU has Reset.
- Lights flashing rapidly = Memory failure.
- Any light flashing dimly indicates that the Digital Processor is trying to send data but the CPU is not accepting the channel.  This could also mean a QAP module failure.
**QVI** Quanterra VME Bus Interface Modules
**The top light (green) ON For 1 second duration at each minute = Normal operation**.
- This occurs when the 1 PPM (1 Pulse Per Minute) signal is received from the GPS receiver.
- Note: The GPS receiver will not output signals until it has locked onto a satellite.
**Middle light (yellow) Flashing brightly and rapidly once each second = Normal operation**.
**The bottom light (red) Flashing brightly and rapidly once each second = Normal operation.**
